OEM easy installation
---------------------
1. Remove all dots from the factory image filename (except the dot
before file extension)
2. Upload and update the firmware via the original web interface
3. Two options are possible after the reboot:
a. OpenWrt - that's OK, the mission accomplished
b. Stock firmware - install Stock firmware (to switch booflag from
Sercomm0 to Sercomm1) and then OpenWrt factory image.
Return to Stock
---------------
1. Change the bootflag to Sercomm1 in OpenWrt CLI and then reboot:
printf 1 | dd bs=1 seek=7 count=1 of=/dev/mtdblock2
reboot
2. Install stock firmware via the web OEM firmware interface
Recovery
--------

(cherry picked from commit 2d6784a033)
This commit moves a part of the code from the "sercomm-factory-cqr" recipe
to the separate "sercomm-mkhash" recipe. This simplifies recipes and
allows insert additional recipes between these code blocks (required for
the future support for Beeline SmartBox PRO router).
dd automatically fills the file by 0x00 if the filesize is less than
offset where we start writing. We drop such dd command so we need to add
--extra-padding-size 0x190 to the sercomm-pid.py call.

the pre-DSA era.
Recovery Mode:
* Press reset button, power up the device, wait for about 10sec.
* Upload sysupgrade image through the firmware recovery mode web page at
192.168.1.1.

When you see the following output on the console:
relocate_code Pointer at: 87f1c000
type in the super secure password:
1234567890
Then select TFTP boot from RAM by selecting option 1 in the boot menu.
As Linksys decided to leave out a basic TFTP configuration you need to
set server- & client ip as well as the image filename the device will
search for. You need to use the initramfs openwrt image for the TFTP
boot process.
Once openwrt has booted up, upload the sysupgrade image via scp and run
sysupgrade as normal.

This commit adds factory.bin image for TP-Link EC330-G5u v1. This allows
to install OpenWrt without connecting a serial cable (UART).
Installation using factory image
--------------------------------
Tested with "3.16.0 0.9.1 v6037.0 Build 191016 Rel.30619nb" TP-Link
firmware.
1. Login to the router web interface (http://192.168.0.1/ by default) and
save running config to "conf.bin" file
2. Open configuration file in any TP-Link config editor (e.g.
https://jahed.github.io/tp-link-config-editor/)
3. Find "DeviceInfo" section and insert a new string "<Description
val="Modem Router`telnetd -p 1023 -l login`" />" according to the
following example:
<DeviceInfo>
...
<Description val="Modem Router`telnetd -p 1023 -l login`" />
...
</DeviceInfo>
4. Save configuration file and upload changed configuration using stock
firmware interface
5. Login using telnet to IP:192.168.0.1 (Username:admin, password:1234)
6. Run "cat /proc/mtd | grep mtd7"
a. If the result is 'mtd7: 03000000 00020000 "rootfs" 03400000',
then install stock firmware using web interface to toggle booted
firmware image from "os1" to "os0"
b. If the result is 'mtd7: 03000000 00020000 "rootfs" 00400000',
then all is ok, go to the next step
7. Set up a tftp server with OpenWrt factory.bin image (IP:192.168.0.100
in this example)
8. Login using telnet to 192.168.0.1
9. Download OpenWrt factory.bin image from the tftp server:
cd /tmp
tftp -g -r factory.bin 192.168.0.100
10. Write OpenWrt factory.bin image:
dd if=/tmp/factory.bin of=/dev/mtdblock1
11. Power cycle the router

The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.
Specifications
==============
SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)
MAC address assignment
======================
The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.
The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.
Installation (web interface)
============================
The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.
The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.
1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy
NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.
Installation (UART method)
==========================
The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:
1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation
Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:
nand read 1800000 53c0000 800
mw.b 1800004 1 1
nand erase 53c0000 800
nand write 1800000 53c0000 800
This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.
Back to stock
=============
It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.
It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:
mtd write zyxel.bin Kernel2
echo -ne "\x02" | dd of=/dev/mtdblock7 count=1 bs=1 seek=4 conv=notrunc

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.
"Config2" seems to be the config storage used by the stock firmware.
"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".
OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```
The OpenWrt image must have 96 bytes of padding in the header.
MAC addresses on OEM firmware:
| | location on the flash | notes |
|------ |----------------------- |---------- |
| lan (eth2) | factory + 0xe000 | on label |
| wan (eth3) | factory + 0xe006 | |
| 2.4g (rax0) | not on flash | lan + 1 |
| 5g (ra0) | not on flash | lan + 2 |
Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.
Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.
1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`
Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.
* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

factory reset with the reset button
connect ethernet to a computer
OEM webpage at 192.168.0.1
username and password 'admin'
Navigate to gear icon, "Device Management", "Tools"
select the factory.dlf image
Upload and verify checksum
Method 2: Serial to upload initramfs:
Follow directions for TFTP recovery
upload and boot initramfs and do a sysupgrade
**TFTP recovery:**
Requires UART serial console, reset button does nothing
rename initramfs-kernel.bin to 'uImageEPG600'
make available on TFTP server at 192.168.99.8
power board, interrupt boot with "4"
execute `tftpboot` and `bootm` (with the load address)
**Return to OEM:**
Images from OEM are provided, but not compatible
with openwrt sysupgrade. So it must be modified.
Alternatively, back up all mtd partitions before flashing
**Note on switch registers:**
The necessary registers needed for the QCA8337 switch
can be read from interrupted boot (tftpboot, bootm)
by using the following lines in the switch driver ar8327.c
in the function 'ar8327_hw_config_of'
where 'qca,ar8327-initvals' is parsed from DTS
before the new register values are written:
pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));

Device is the same as Xiaomi Mi Router 4A Gigabit, except of:
- 5G WiFi is MT7663
- addresses of leds, wifi and eth ports are slightly changed
Specs:
SoC: MT7621
CPU: 2 x 880 MHz
ROM: 16 MB
RAM: 128 MB
WLAN: MT7603, MT7663
MAC addresses:
WAN **** factory 0xe006 (label)

2.4 GHz *:f8 factory 0x0000+0x4 (mtd-eeprom+0x4)
5 GHz *:f9 factory 0x8000+0x4 (mtd-eeprom+0x4)
Installation:
Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.
Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155
In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
# mtd -e OS1 -r write /tmp/sysupgrade.bin OS1
Recovery:
Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition
One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released
- blinking blue wan LED will indicate the end of the flashing process,
now router can be rebooted

Add support for D-Link DIR-1935 A1 based on similarities to DIR-882 A1,
DIR-867 A1 and other DIR-8xx A1 models. Existing DIR-882 A1 openwrt
"factory" firmware installs without modificaitons via the D-Link
Recovery GUI and has no known incompatibilities with the DIR-1935 A1.
Changes to be committed:
new file: target/linux/ramips/dts/mt7621_dlink_dir-1935-a1.dts
modified: target/linux/ramips/image/mt7621.mk
modified: target/linux/ramips/mt7621/base-files/etc/board.d/01_leds
Specifications:
* Board: Not known
* SoC: MediaTek MT7621 Family
* RAM: 128 MB (DDR3)
* Flash: 16 MB (SPI NOR)
* WiFi: MediaTek MT7615 Family (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 3.0
* Buttons: Reset, WiFi Toggle, WPS
* LEDs: Power (green/orange), Internet (green/orange), WiFi 2.4G (green),

Notes:
* 160MHz 5GHz is available in LuCi but does not appear to work (i.e. no
SSID is visible in wifi scanning apps on other devices) with either
official DIR-882 A1 firmware or a test build for the DIR-1935 A1 based
on the 22.03.2 branch. 80 MHz 5GHz works.
Serial port:
* Untested (potential user damage/error)
* Expected to be identical to other DIR-8xx A1 models:
* Parameters: 57600, 8N1
* Location: J1 header (close to the Reset, WiFi and WPS buttons)
* Pinout: 1 - VCC
2 - RXD
3 - TXD
4 - GND
Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
button, then re-plug it. Keep the reset button pressed until the power
LED starts flashing orange, manually assign a static IP address under
the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1

This device is a 'Range extender' variant of the Xiaomi 4A router.
Its identical to the 100m non-intl/chinese version as much as it can run
the same firmware, differences being form factor, LEDs, WPS button
and one 100M port only.
The stock firmware differs significantly, being 'app managed only'.
