d79380ac1d ath79: ZTE MF286R: add comgt-ncm to DEVICE_PACKAGES
When adding support to the router's built-in modem, this required
package was omitted, because it was already enabled in the image
configuration in use for testing, and this went unnoticed.
In result, the modem still isn't fully supported in official images.
As it is the primary WAN interface, add the missing package.

ff9264fabc ath79: add support for Sophos AP100/AP55 family
The Sophos AP100, AP100C, AP55, and AP55C are dual-band 802.11ac access
points based on the Qualcomm QCA9558 SoC. They share PCB designs with
several devices that already have partial or full support, most notably the
Devolo DVL1750i/e.

The AP100 and AP100C are hardware-identical to the AP55 and AP55C, however
the 55 models' ART does not contain calibration data for their third chain
despite it being present on the PCB.

Specifications common to all models:
 - Qualcomm QCA9558 SoC @ 720 MHz (MIPS 74Kc Big-endian processor)
 - 128 MB RAM
 - 16 MB SPI flash
 - 1x 10/100/1000 Mbps Ethernet port, 802.3af PoE-in
 - Green and Red status LEDs sharing a single external light-pipe
 - Reset button on PCB[1]
 - Piezo beeper on PCB[2]
 - Serial UART header on PCB
 - Alternate power supply via 5.5x2.1mm DC jack @ 12 VDC

Unique to AP100 and AP100C:
 - 3T3R 2.4GHz 802.11b/g/n via SoC WMAC
 - 3T3R 5.8GHz 802.11a/n/ac via QCA9880 (PCI Express)

AP55 and AP55C:
 - 2T2R 2.4GHz 802.11b/g/n via SoC WMAC
 - 2T2R 5.8GHz 802.11a/n/ac via QCA9880 (PCI Express)

AP100 and AP55:
 - External RJ45 serial console port[3]
 - USB 2.0 Type A port, power controlled via GPIO 11

Flashing instructions:

This firmware can be flashed either via a compatible Sophos SG or XG
firewall appliance, which does not require disassembling the device, or via
the U-Boot console available on the internal UART header.

To flash via XG appliance:
 - Register on Sophos' website for a no-cost Home Use XG firewall license
 - Download and install the XG software on a compatible PC or virtual
   machine, complete initial appliance setup, and enable SSH console access
 - Connect the target AP device to the XG appliance's LAN interface
 - Approve the AP from the XG Web UI and wait until it shows as Active
   (this can take 3-5 minutes)
 - Connect to the XG appliance over SSH and access the Advanced Console
   (Menu option 5, then menu option 3)
 - Run `sudo awetool` and select the menu option to connect to an AP via
   SSH. When prompted to enable SSH on the target AP, select Yes.
 - Wait 2-3 minutes, then select the AP from the awetool menu again. This
   will connect you to a root shell on the target AP.
 - Copy the firmware to /tmp/openwrt.bin on the target AP via SCP/TFTP/etc
 - Run `mtd -r write /tmp/openwrt.bin astaro_image`
 - When complete, the access point will reboot to OpenWRT.

To flash via U-Boot serial console:
 - Configure a TFTP server on your PC, and set IP address 192.168.99.8 with
   netmask 255.255.255.0
 - Copy the firmware .bin to the TFTP server and rename to 'uImage_AP100C'
 - Open the target AP's enclosure and locate the 4-pin 3.3V UART header [4]
 - Connect the AP ethernet to your PC's ethernet port
 - Connect a terminal to the UART at 115200 8/N/1 as usual
 - Power on the AP and press a key to cancel autoboot when prompted
 - Run the following commands at the U-Boot console:
    - `tftpboot`
    - `cp.b $fileaddr 0x9f070000 $filesize`
    - `boot`
 - The access point will boot to OpenWRT.

MAC addresses as verified by OEM firmware:

use   address     source
LAN   label       config 0x201a (label)
2g    label + 1   art 0x1002    (also found at config 0x2004)
5g    label + 9   art 0x5006

Increments confirmed across three AP55C, two AP55, and one AP100C.

These changes have been tested to function on both current master and
21.02.0 without any obvious issues.

[1] Button is present but does not alter state of any GPIO on SoC
[2] Buzzer and driver circuitry is present on PCB but is not connected to
    any GPIO. Shorting an unpopulated resistor next to the driver circuitry
    should connect the buzzer to GPIO 4, but this is unconfirmed.
[3] This external RJ45 serial port is disabled in the OEM firmware, but
    works in OpenWRT without additional configuration, at least on my
    three test units.
[4] On AP100/AP55 models the UART header is accessible after removing
    the device's top cover. On AP100C/AP55C models, the PCB must be removed
    for access; three screws secure it to the case.
    Pin 1 is marked on the silkscreen. Pins from 1-4 are 3.3V, GND, TX, RX

321ec22f52 ath79: add support for Yuncore A930
Specification:

- QCA9533 (650 MHz), 64 or 128MB RAM, 16MB SPI NOR
- 2x 10/100 Mbps Ethernet, with 802.3at PoE support (WAN)
- 2T2R 802.11b/g/n 2.4GHz

Flash instructions:

If your device comes with generic QSDK based firmware, you can login
over telnet (login: root, empty password, default IP: 192.168.188.253),
issue first (important!) 'fw_setenv' command and then perform regular
upgrade, using 'sysupgrade -n -F ...' (you can use 'wget' to download

  fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
  sysupgrade -n -F openwrt-...-yuncore_...-squashfs-sysupgrade.bin

In case your device runs firmware with YunCore custom GUI, you can use
U-Boot recovery mode:

1. Set a static IP 192.168.0.141/24 on PC and start TFTP server with
   'tftp' image renamed to 'upgrade.bin'
2. Power the device with reset button pressed and release it after 5-7
   seconds, recovery mode should start downloading image from server
   (unfortunately, there is no visible indication that recovery got
   enabled - in case of problems check TFTP server logs)

85d581a64b ath79: Move TPLink WPA8630Pv2 to ath79-tiny target
These devices only have 6MiB available for firmware, which is not
enough for recent release images, so move these to the tiny target.

Note for users sysupgrading from the previous ath79-generic snapshot
images:

The tiny target kernel has a 4Kb flash erase block size instead
of the generic target's 64kb. This means the JFFS2 overlay partition
containing settings must be reformatted with the new block size or else
there will be data corruption.

To do this, backup your settings before upgrading, then during the
sysupgrade, de-select "Keep Settings". On the CLI, use "sysupgrade -n".

If you forget to do this and your system becomes unstable after
upgrading, you can do this to format the partition and recover:

* Reboot
* Press RESET when Power LED blinks during boot to enter Failsafe mode
* SSH to 192.168.1.1
* Run "firstboot" and reboot

41be1a2de2 ath79: add support for Araknis AN-700-AP-I-AC
FCC ID: 2AG6R-AN700APIAC

Araknis AN-700-AP-I-AC is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP1750
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - QCA9558 SOC		MIPS 74kc, 2.4 GHz WMAC, 3x3
  - QCA9880 WLAN	PCI card, 5 GHz, 3x3, 26dBm
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM	NT5TU32M16
  - UART console	J10, populated, RX shorted to ground
  - 4 antennas		5 dBi, internal omni-directional plates
  - 4 LEDs		power, 2G, 5G, wps
  - 1 button		reset

  NOTE: all 4 gpio controlled LEDS are viewed through the same lightguide
	therefore, the power LED is off for default state

**MAC addresses:**

  MAC address labeled as ETH
  Only one Vendor MAC address in flash at art 0x0

  eth0 ETH  *:xb art 0x0
  phy1 2.4G *:xc ---
  phy0 5GHz *:xd ---

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin at J10

**Installation:**

  Method 1: Firmware upgrade page:

    (if you cannot access the APs webpage)
    factory reset with the reset button
    connect ethernet to a computer
    OEM webpage at 192.168.20.253
    username and password 'araknis'
    make a new password, login again...

    Navigate to 'File Management' page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm
    wait about 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  Method 1: Serial to load Failsafe webpage (above)

  Method 2: delete a checksum from uboot-env
  this will make uboot load the failsafe image at next boot
  because it will fail the checksum verification of the image

    ssh into openwrt and run
    `fw_setenv rootfs_checksum 0`
    reboot, wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    select OEM firmware image and click upgrade

  Method 3: backup mtd partitions before upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs-kernel.bin to '0101A8C0.img'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot with serial console
  execute `tftpboot` and `bootm 0x81000000`

  NOTE: TFTP may not be reliable due to bugged bootloader
	set MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software is built using SDKs from Senao
  which is based on a heavily modified version
  of Openwrt Kamikaze or Altitude Adjustment.
  One of the many modifications is sysupgrade being performed by a custom script.
  Images are verified through successful unpackaging, correct filenames
  and size requirements for both kernel and rootfs files, and that they
  start with the correct magic numbers (first 2 bytes) for the respective headers.

  Newer Senao software requires more checks but their script
  includes a way to skip them.

  The OEM upgrade script is at
  /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be less than 1536k
  and the OEM upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied at the PHY side,
  using the at803x driver `phy-mode` setting through the DTS.
  Therefore, the Ethernet Configuration registers for GMAC0
  do not need the bits for RGMII delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

    Click Continue to confirm
    wait about 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  Method 1: Serial to load Failsafe webpage (above)

  Method 2: delete a checksum from uboot-env
  this will make uboot load the failsafe image at next boot
  because it will fail the checksum verification of the image

    ssh into openwrt and run
    `fw_setenv rootfs_checksum 0`
    reboot, wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    select OEM firmware image and click upgrade

  Method 3: backup mtd partitions before upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs-kernel.bin to '0101A8C0.img'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot with serial console
  execute `tftpboot` and `bootm 0x81000000`

  NOTE: TFTP may not be reliable due to bugged bootloader
	set MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software is built using SDKs from Senao
  which is based on a heavily modified version
  of Openwrt Kamikaze or Altitude Adjustment.
  One of the many modifications is sysupgrade being performed by a custom script.
  Images are verified through successful unpackaging, correct filenames
  and size requirements for both kernel and rootfs files, and that they
  start with the correct magic numbers (first 2 bytes) for the respective headers.

  Newer Senao software requires more checks but their script
  includes a way to skip them.

  The OEM upgrade script is at
  /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be less than 1536k
  and the OEM upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied at the PHY side,
  using the at803x driver `phy-mode` setting through the DTS.
  Therefore, the Ethernet Configuration registers for GMAC0
  do not need the bits for RGMII delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

Araknis AN-300-AP-I-N is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EWS310AP
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - AR9344 SOC		MIPS 74kc, 2.4 GHz WMAC, 2x2
  - AR9382 WLAN		PCI on-board 168c:0030, 5 GHz, 2x2
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM	1839ZFG V59C1512164QFJ25
  - UART console	J10, populated, RX shorted to ground
  - 4 antennas		5 dBi, internal omni-directional plates
  - 4 LEDs		power, 2G, 5G, wps

  MAC address labeled as ETH
  Only one Vendor MAC address in flash at art 0x0

  eth0 ETH  *:7d art 0x0
  phy1 2.4G *:7e ---
  phy0 5GHz *:7f ---

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin at J10

9c335accfe ath79: add support for TP-Link Archer A9 v6
TP-Link Archer A9 v6 (FCCID: TE7A9V6) is an AC1900 Wave-2 gigabit home
router based on a combination of Qualcomm QCN5502 (most likely a 4x4:4
version of the QCA9563 WiSOC), QCA9984 and QCA8337N.

The vendor's firmware content reveals that the same device might be
available on the US market under name 'Archer C90 v6'. Due to lack of
access to such hardware, support introduced in this commit was tested
only on the EU version (sold under 'Archer A9 v6' name).

Based on the information on the PL version of the vendor website, this
device has been already phased out and is no longer available.

Specifications:

- Qualcomm QCN5502 (775 MHz)
- 128 MB of RAM (DDR2)
- 16 MB of flash (SPI NOR)
- 5x Gbps Ethernet (Qualcomm QCA8337N over SGMII)
- Wi-Fi:
  - 802.11b/g/n on 2.4 GHz: Qualcomm QCN5502* in 4x4:4 mode
  - 802.11a/n/ac on 5 GHz: Qualcomm QCA9984 in 3x3:3 mode
  - 3x non-detachable, dual-band external antennas (~3.5 dBi for 5 GHz,
    ~2.2 dBi for 2.4 GHz, IPEX/U.FL connectors)
  - 1x internal PCB antenna for 2.4 GHz (~1.8 dBi)
- 1x USB 2.0 Type-A
- 11x LED (4x connected to QCA8337N, 7x connected to QCN5502)
- 2x button (reset, WPS)
- UART (4-pin, 2.54 mm pitch) header on PCB (not populated)
- 1x mechanical power switch
- 1x DC jack (12 V)

  *) unsupported due to missing support for QCN550x in ath9k

UART system serial console notice:

The RX signal of the main SOC's UART on this device is shared with the
WPS button's GPIO. The first-stage U-Boot by default disables the RX,
resulting in a non-functional UART input.
If you press and keep 'ENTER' on the serial console during early
boot-up, the first-stage U-Boot will enable RX input.

Vendor firmware allows password-less access to the system over serial.

Flash instruction (vendor GUI):

1. It is recommended to first upgrade vendor firmware to the latest
   version (1.1.1 Build 20210315 rel.40637 at the time of writing).
2. Use the 'factory' image directly in the vendor's GUI.

Flash instruction (TFTP based recovery in second-stage U-Boot):

1. Rename 'factory' image to 'ArcherA9v6_tp_recovery.bin'
2. Setup a TFTP server on your PC with IP 192.168.0.66/24.
3. Press and hold the reset button for ~5 sec while turning on power.
4. The device will download image, flash it and reboot.

Flash instruction (web based recovery in first-stage U-Boot):

1. Use 'CTRL+C' during power-up to enable CLI in first-stage U-Boot.
2. Connect a PC with IP set to 192.168.0.1 to one of the LAN ports.
3. Issue 'httpd' command and visit http://192.168.0.1 in browser.
4. Use the 'factory' image.

If you would like to restore vendor's firmware, follow one of the
recovery methods described above.

7ac8da0060 ath79: support ZTE MF286A/R
ZTE MF286A and MF286R are indoor LTE category 6/7 CPE router with simultaneous
dual-band 802.11ac plus 802.11n Wi-Fi radios and quad-port gigabit
Ethernet switch, FXS and external USB 2.0 port.

Hardware highlights:
- CPU: QCA9563 SoC at 775MHz,
- RAM: 128MB DDR2,
- NOR Flash: MX25L1606E 2MB SPI Flash, for U-boot only,
- NAND Flash: W25N01GV 128MB SPI NAND-Flash, for all other data,
- Wi-Fi 5GHz: QCA9886 2x2 MIMO 802.11ac Wave2 radio,
- WI-Fi 2.4GHz: QCA9563 3x3 MIMO 802.11n radio,
- Switch: QCA8337v2 4-port gigabit Ethernet, with single SGMII CPU port,
- WWAN:
  [MF286A] MDM9230-based category 6 internal LTE modem
  [MF286R] PXA1826-based category 7 internal LTE modem
  in extended  mini-PCIE form factor, with 3 internal antennas and
  2 external antenna connections, single mini-SIM slot.
- FXS: one external ATA port (handled entirely by modem part) with two
  physical connections in parallel,
- USB: Single external USB 2.0 port,
- Switches: power switch, WPS, Wi-Fi and reset buttons,
- LEDs: Wi-Fi, Test (internal). Rest of LEDs (Phone, WWAN, Battery,
  Signal state) handled entirely by modem. 4 link status LEDs handled by
  the switch on the backside.
- Battery: 3Ah 1-cell Li-Ion replaceable battery, with charging and
  monitoring handled by modem.
- Label MAC device: eth0

The device shares many components with previous model, MF286, differing
mostly by a Wave2 5GHz radio, flash layout and internal LED color.
In case of MF286A, the modem is the same as in MF286. MF286R uses a
different modem based on Marvell PXA1826 chip.

Internal modem of MF286A is supported via uqmi, MF286R modem isn't fully
supported, but it is expected to use comgt-ncm for connection, as it
uses standard 3GPP AT commands for connection establishment.

Console connection: connector X2 is the console port, with the following
pinout, starting from pin 1, which is the topmost pin when the board is
upright:
- VCC (3.3V). Do not use unless you need to source power for the
  converer from it.
- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.

Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.

STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.

STEP 1: gaining root shell:

Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.

Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
  then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
  "http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.

Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.

- Set IP of your computer to 192.168.0.22. (or appropriate subnet if
  changed)
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
  https://busybox.net/downloads/binaries/1.21.1/busybox-mips
  and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
  filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
  field named "addURLFilter", so it looks like this:
  <input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
    class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.0.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
  execute it. You should be able to log in at port 23, using
  "admin/admin" as credentials.

Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.

STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.
It is highly recommended to perform backup using both methods, to avoid
hassle of reassembling firmware images in future, if a restore is
needed.

Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:

  ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
  ssh root@192.168.1.1: cat /dev/mtd9 > mtd9_ubi.bin

And keep them in a safe place, should a restore be needed in future.

Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
  port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:

  cat /proc/mtd

  It should show the following:
  mtd0: 000a0000 00010000 "u-boot"
  mtd1: 00020000 00010000 "u-boot-env"

  mtd12: 00300000 00020000 "kernel"
  mtd13: 01a00000 00020000 "rootfs"

  mtd15: 03200000 00020000 "fota"
  mtd16: 01d00000 00020000 "firmware"

  Differences might indicate that this is NOT a MF286A device but
  one of other variants.
- Copy over all MTD partitions, for example by executing the following:

  for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15; do cat /dev/mtd$i > \
  /var/usb_disk/mtd$i; done

  "Firmware" partition can be skipped, it is a concatenation
  of "kernel" and "rootfs".

- If the count of MTD partitions is different, this might indicate that
  this is not a MF286A device, but one of its other variants.
- (optionally) rename the files according to MTD partition names from
  /proc/mtd
- Unmount the filesystem:

  umount /var/usb_disk; sync

  and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
  firmware. This is especially important, because stock firmware for
  this device is not available officially, and is usually customized by
  the mobile providers.

STEP 3: Booting initramfs image:

Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
  set your computer's IP address as 192.168.0.22. This is the default
  expected by U-boot. You may wish to change that, and alter later
  commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:

  setenv serverip 192.168.0.22
  setenv ipaddr 192.168.0.1
  tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin
  bootm 0x81000000

  (Replace server IP and router IP as needed). There is no  emergency
  TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
  installation.

Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- After backing up the previous MTD contents, write the images to the
  "firmware" MTD device, which conveniently concatenates "kernel" and
  "rootfs" partitions that can fit the initramfs image:

  nandwrite -p /dev/<firmware-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286a-initramfs-kernel.bin

- If write is OK, reboot the device, it will reboot to OpenWrt
  initramfs:

  reboot -f

- After rebooting, SSH into the device and use sysupgrade to perform
  proper installation.

Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
  flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
  and name it root_uImage:

  dd if=/dev/zero of=padding.bin bs=8M count=1

  cat padding.bin openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin >
  root_uImage

- Set up a TFTP server at 192.0.0.1/8. Router will use random address
  from that range.
- Put the previously generated "root_uImage" into TFTP server root
  directory.
- Deliberately erase "kernel" partition" using stock firmware after
  taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
  initramfs image, which will let you perform actual installation using
  sysupgrade. This might take a considerable time, sometimes the router
  doesn't establish Ethernet link properly right after booting. Be
  patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
  light up. At this moment, perform power-on reset, and wait for OpenWrt
  initramfs to finish booting. Then proceed to actual installation.

STEP 4: Actual installation:
- Set your computer IP to 192.168.1.22/24
- scp the sysupgrade image to the device:

  scp openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin \
  root@192.168.1.1:/tmp/

- ssh into the device and execute sysupgrade:

  sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin

- Wait for router to reboot to full OpenWrt.

STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:

config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth '<auth>' # As required, usually 'none'
        option pincode '<pin>' # If required by SIM
        option apn '<apn>' # As required by ISP
        option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'

For example, the following works for most polish ISPs
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth 'none'
        option apn 'internet'
        option pdptype 'ipv4'

The required minimum is:
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
In this case, the modem will use last configured APN from stock
firmware - this should work out of the box, unless your SIM requires
PIN which can't be switched off.

If you have build with LuCI, installing luci-proto-qmi helps with this
task.

Restoring the stock firmware:

Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware
The only partitions you really care about are "web", "kernel", and
"rootfs". These are required to restore the stock firmware through
factory TFTP recovery.

Because kernel partition was enlarged, compared to stock
firmware, the kernel and rootfs MTDs don't align anymore, and you need
to carve out required data if you only have backup from stock FW:
- Prepare kernel image
  cat mtd12_kernel.bin mtd13_rootfs.bin > owrt_kernel.bin
  truncate -s 4M owrt_kernel_restore.bin
- Cut off first 1MB from rootfs
  dd if=mtd13_rootfs.bin of=owrt_rootfs.bin bs=1M skip=1
- Prepare image to write to "ubi" meta-partition:
  cat mtd6_reserved2.bi mtd7_cfg-param.bin mtd8_log.bin mtd9_oops.bin \
  mtd10_reserved3.bin mtd11_web.bin owrt_rootfs.bin > \
  owrt_ubi_ubi_restore.bin

You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.

Method 1: Using initramfs:
This method is recmmended if you took your backup from within OpenWrt
initramfs, as the reassembly is not needed.
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
  (scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
  mtd write <kernel_mtd> mtd4_kernel.bin
  rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
  restore them individually. Otherwise you might run out of space in
  tmpfs:

  (scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
  rm mtd3_ubiconcat0.bin

  (scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
  rm mtd5_ubiconcat1.bin

- If the write was correct, force a device reboot with

  reboot -f

Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
  your drive
- Mount your flash drive

  mkdir /tmp/usb

  mount /dev/sda1 /tmp/usb

- Remount your UBI volume at /overlay to R/O

  mount -o remount,ro /overlay

- Write back the kernel and ubi partitions from USB drive

  cd /tmp/usb
  mtd write mtd4_kernel.bin /dev/<kernel_mtd>

  mtd write mtd9_ubi.bin /dev/<kernel_ubi>

- If everything went well, force a device reboot with
  reboot -f

Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.

Method 3: using built-in TFTP recovery:
This method is recommended if you took backups using stock firmware.
- Assemble a recovery rootfs image from backup of stock partitions by
  concatenating "web", "kernel", "rootfs" images dumped from the device,
  as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
  TFTP pre-installation method.

Quirks and known issuesa
- It was observed, that CH340-based USB-UART converters output garbage
  during U-boot phase of system boot. At least CP2102 is known to work
  properly.
- Kernel partition size is increased to 4MB compared to stock 3MB, to
  accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
  image is at 2.5MB which is dangerously close to the limit. This has no
  effect on booting the system - but keep that in mind when reassembling
  an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
  you used before in stock firmware first. If you need to change it,
  please use protocok '3g' to establish connection once, or use the
  following command to change APN (and optionally IP type) manually:
  echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the blue debug LED hidden
  inside the case. All other LEDs are controlled by modem, on which the
  router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
  correct GPIO mapping. All other LEDs are controlled by modem,
  including this one in stock firmware. GPIO19, mapped there only acts
  as a gate, while the actual signal source seems to be 5GHz Wi-Fi
  radio, however it seems it is not the LED exposed by ath10k as
  ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
  reset of whole board, not only the modem. It is attached to
  gpio-restart driver, to restart the modem on reboot as well, to ensure
  QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
  for OpenWrt operation at all - have fun lurking around.
  The same modem module is used as in older MF286.

- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.

Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.

STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.

STEP 1: gaining root shell:

Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.

Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
  then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
  "http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.

Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.

- Set IP of your computer to 192.168.1.22.
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
  https://busybox.net/downloads/binaries/1.21.1/busybox-mips
  and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
  filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
  field named "addURLFilter", so it looks like this:
  <input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
    class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.1.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
  execute it. You should be able to log in at port 23, using
  "admin/admin" as credentials.

Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.

STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.

Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:

  ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
  ssh root@192.168.1.1: cat /dev/mtd8 > mtd8_ubi.bin

And keep them in a safe place, should a restore be needed in future.

Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
  port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:

  cat /proc/mtd

  It should show the following:
  mtd0: 00080000 00010000 "uboot"
  mtd1: 00020000 00010000 "uboot-env"
  mtd2: 00140000 00020000 "fota-flag"
  mtd3: 00140000 00020000 "caldata"
  mtd4: 00140000 00020000 "mac"
  mtd5: 00600000 00020000 "cfg-param"
  mtd6: 00140000 00020000 "oops"
  mtd7: 00800000 00020000 "web"
  mtd8: 00300000 00020000 "kernel"
  mtd9: 01f00000 00020000 "rootfs"
  mtd10: 01900000 00020000 "data"
  mtd11: 03200000 00020000 "fota"

  Differences might indicate that this is NOT a vanilla MF286 device but
  one of its later derivatives.
- Copy over all MTD partitions, for example by executing the following:

  for i in 0 1 2 3 4 5 6 7 8 9 10 11; do cat /dev/mtd$i > \
  /var/usb_disk/mtd$i; done

- If the count of MTD partitions is different, this might indicate that
  this is not a standard MF286 device, but one of its later derivatives.
- (optionally) rename the files according to MTD partition names from
  /proc/mtd
- Unmount the filesystem:

  umount /var/usb_disk; sync

  and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
  firmware. This is especially important, because stock firmware for
  this device is not available officially, and is usually customized by
  the mobile providers.

STEP 3: Booting initramfs image:

Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
  set your computer's IP address as 192.168.1.22. This is the default
  expected by U-boot. You may wish to change that, and alter later
  commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:

  setenv serverip 192.168.1.22
  setenv ipaddr 192.168.1.1
  tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin
  bootm 0x81000000

  (Replace server IP and router IP as needed). There is no  emergency
  TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
  installation.

Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- Split the image into two parts on 3MB partition size boundary, which
  is the size of kernel partition. Pad the output of second file to
  eraseblock size:

  dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
  bs=128k count=24 \
  of=openwrt-ath79-zte_mf286-intermediate-kernel.bin

  dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
  bs=128k skip=24 conv=sync \
  of=openwrt-ath79-zte_mf286-intermediate-rootfs.bin

- Copy over /usr/bin/flash_eraseall and /usr/bin/nandwrite utilities to
  /tmp. This is CRITICAL for installation, as erasing rootfs will cut
  you off from those tools on flash!

- After backing up the previous MTD contents, write the images to the
  respective MTD devices:

  /tmp/flash_eraseall /dev/<kernel-mtd>

  /tmp/nandwrite /dev/<kernel-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286-intermediate-kernel.bin

  /tmp/flash_eraseall /dev/<kernel-mtd>

  /tmp/nandwrite /dev/<rootfs-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286-intermediate-rootfs.bin

- Ensure that no bad blocks were present on the devices while writing.
  If they were present, you may need to vary the split  between
  kernel and rootfs parts, so U-boot reads a valid uImage after skipping
  the bad blocks. If it fails, you will be left with method 3 (below).
- If write is OK, reboot the device, it will reboot to OpenWrt
  initramfs:

  reboot -f

- After rebooting, SSH into the device and use sysupgrade to perform
  proper installation.

Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
  flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
  and name it root_uImage:

  dd if=/dev/zero of=padding.bin bs=8M count=1

  cat padding.bin openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin >
  root_uImage

- Set up a TFTP server at 192.0.0.1/8. Router will use random address
  from that range.
- Put the previously generated "root_uImage" into TFTP server root
  directory.
- Deliberately erase "kernel" partition" using stock firmware after
  taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
  initramfs image, which will let you perform actual installation using
  sysupgrade. This might take a considerable time, sometimes the router
  doesn't establish Ethernet link properly right after booting. Be
  patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
  light up. At this moment, perform power-on reset, and wait for OpenWrt
  initramfs to finish booting. Then proceed to actual installation.

STEP 4: Actual installation:
- scp the sysupgrade image to the device:

  scp openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin \
  root@192.168.1.1:/tmp/

- ssh into the device and execute sysupgrade:

  sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin

- Wait for router to reboot to full OpenWrt.

STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:

config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth '<auth>' # As required, usually 'none'
        option pincode '<pin>' # If required by SIM
        option apn '<apn>' # As required by ISP
        option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'

For example, the following works for most polish ISPs
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth 'none'
        option apn 'internet'
        option pdptype 'ipv4'

If you have build with LuCI, installing luci-proto-qmi helps with this
task.

Restoring the stock firmware:

Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware.
The only partitions you really care about are "web", "kernel", and
"rootfs". For easy padding and possibly restoring configuration, you can
concatenate most of them into images written into "ubi" meta-partition
in OpenWrt. To do so, execute something like:

cat mtd5_cfg-param.bin mtd6-oops.bin mtd7-web.bin mtd9-rootfs.bin > \
mtd8-ubi_restore.bin

You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.

Method 1: Using initramfs:
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
  (scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
  mtd write <kernel_mtd> mtd4_kernel.bin
  rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
  restore them individually. Otherwise you might run out of space in
  tmpfs:

  (scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
  rm mtd3_ubiconcat0.bin

  (scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
  rm mtd5_ubiconcat1.bin

- If the write was correct, force a device reboot with

  reboot -f

Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
  your drive
- Mount your flash drive

  mkdir /tmp/usb

  mount /dev/sda1 /tmp/usb

- Remount your UBI volume at /overlay to R/O

  mount -o remount,ro /overlay

- Write back the kernel and ubi partitions from USB drive

  cd /tmp/usb
  mtd write mtd4_kernel.bin /dev/<kernel_mtd>

  mtd write mtd8_ubi.bin /dev/<kernel_ubi>

- If everything went well, force a device reboot with
  reboot -f

Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.

Method 3: using built-in TFTP recovery (LAST RESORT):
- Assemble a recovery rootfs image from backup of stock partitions by
  concatenating "web", "kernel", "rootfs" images dumped from the device,
  as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
  TFTP pre-installation method.

Quirks and known issues
- Kernel partition size is increased to 4MB compared to stock 3MB, to
  accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
  image is at 2.5MB which is dangerously close to the limit. This has no
  effect on booting the system - but keep that in mind when reassembling
  an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
  you used before in stock firmware first. If you need to change it,
  please use protocok '3g' to establish connection once, or use the
  following command to change APN (and optionally IP type) manually:
  echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the green debug LED hidden
  inside the case. All other LEDs are controlled by modem, on which the
  router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
  correct GPIO mapping. All other LEDs are controlled by modem,
  including this one in stock firmware. GPIO19, mapped there only acts
  as a gate, while the actual signal source seems to be 5GHz Wi-Fi
  radio, however it seems it is not the LED exposed by ath10k as
  ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
  reset of whole board, not only the modem. It is attached to
  gpio-restart driver, to restart the modem on reboot as well, to ensure
  QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
  for OpenWrt operation at all - have fun lurking around.
- MAC address shift for 5GHz Wi-Fi used in stock firmware is
  0x320000000000, which is impossible to encode in the device tree, so I
  took the liberty of using MAC address increment of 1 for it, to ensure
  different BSSID for both Wi-Fi interfaces.
