Gain SSH access:
1. Login into web interface (http://apipaddress/computer/login.html),
and download the
configuration(http://apipaddress/computer/config.html).
2. Rename downloaded backup config - 'backup.file to backup.tar.gz',
Enter 'fakeroot' command then decompress the configuration:
tar -zxf backup.tar.gz
3. Edit 'etc/shadow', update (remove) root password:
With password =
'root:$1$xf7D0Hfg$5gkjmvgQe4qJbe1fi/VLy1:19362:0:99999:7:::'
'root:$1$xf7D0Hfg$5gkjmvgQe4qJbe1fi/VLy1:19362:0:99999:7:::'
to
Without password =
'root::0:99999:7:::'
'root::0:99999:7:::'
4. Repack 'etc' directory back to a new backup file:
tar -zcf backup-ssh.tar.gz etc/
5. Rename new config tar.gz file to 'backup-ssh.file'
Exit fakeroot - 'exit'
6. Upload new configuration via web interface, now you
can SSH with the following:
'ssh -vv -o HostKeyAlgorithms=+ssh-rsa \
-o PubkeyAcceptedAlgorithms=+ssh-rsa root@192.168.10.1'.
Backup the mtd partitions
- https://openwrt.org/docs/guide-user/installation/generic.backup
7. Copy openwrt factory firmware to the tmp folder to install via ssh:
'scp -o HostKeyAlgorithms=+ssh-rsa \
-o PubkeyAcceptedAlgorithms=+ssh-rsa \
*-mediatek-filogic-comfast_cf-e393ax-squashfs-factory.bin \
root@192.168.10.1:/tmp/'
'sysupgrade -n -F \
/tmp/*--mediatek-filogic-comfast_cf-e393ax-squashfs-factory.bin'
8. Once led has stopped flashing - Connect via ssh with the
default openwrt ip address - 'ssh root@192.168.1.1'
9. SSH copy the openwrt sysupgrade firmware and upgrade
as per the default instructions.

Acelink EW-7886CAX is an MT7986A (AKA Filogic 830) based access point.
It has 512 MiB of RAM, one 2.5 Gbps PoE (802.3at) Ethernet port and
on-SoC Wi-Fi. There is no printed MAC label (on my unit).
My unit came with Mediatek's firmware (based on OpenWrt 21.02)
installed. It was possible to simply upgrade using OpenWrt's sysupgrade
tool.
Another verified upgrade method is using U-Boot (requires UART). During
every boot there is "U-Boot Boot Menu". Selecting option "2. Upgrade
firmware" allows using U-Boot's tftp client to load and flash factory
image.

To create a correct BL2, I had to add a profile for 'spim:4k+256' as I could not find a way to value the variable 'NAND_TYPE'.
Features and fixes from hitech95 tree has been squashed, I'm attaching his commit message:
The Power LED was not working correctly and not reacting
to the boot process and statuses.
The board has space (footprint) for an unpopulated Zigbee chip,
while we dont know the device model having this chip populated
we have to assure that the common dts doesnt enable
interfaces that share pins with such device.
In this instance the PCIe and the uart1 and uart2 are disabled.
Some of the control PCIE pins seems to be used for the Zigbee chip,
UART1 seems to be used as a flash port while UART2 should be the
main comunication interface of Zigbee chip.
The Zigbee chip should be a EFR32MG21. But the pins used for UART
seems to be not on standard PINS used by other adapters.
So it cannot run firmwares shared on the web.
But it should be possible to build a custom firmware with
the corrtect pinmux.
This commit also contains the following squashed commit from hitech95
- mediatek: fix sysupgrade for Zyxel EX7601-T0 ubootmod
Changes and fixes added in common board:
- added aliases for boot status leds.
- added aliases for the mac-label-device.
- added pin claims for core features (MDIO and UART 0)
- added default LEDs configuration (01_leds)
- added default network configuration (02_network)
- added missing kmod-usb3 module for USB3
- fixed LED names
- fixed reset pin for SLIC chip
- removed unused pinmux configurations and devices
- fix LAN (switch) port numbering
- using nvmem cells for wifi eeprom, dropping deprecated "mediatek,mtd-eeprom"
- proper factory partition and mac address handling
- cleaned up spi_nand sections and partition
Changes and fixxes added in stock layout:
- added NMBM, if u-boot has it, the kernel must be informed.

6. After openwrt boots up, perform sysupgrade.
Note:
1. Since NMBM is disabled, we must back up all partitions.
2. Although we can upgrade new firmware in the stock firmware,
we need the special fit image signature of MediaTek and

Commit mt76: drop default eeprom file for mt7986-firmware
(e3aa645b26) breaks eeprom loading for
Mercusys MR90X v1. As a result WiFi is not working at all.
This commit adds Mercusus MR90x to the caldata script (it works after the
commit mentioned above). And we can safely drop "81_fix_eeprom" script
as it's no longer required.

Add build for the MTK3943 reference board for MT7981B+MT7976C.
**Hardware specification:**
- SoC: MediaTek MT7981B 2x A53
- Flash: various options
- RAM: 256MB DDR3
- Ethernet: 4 x 10/100/1000 Mbps via MT7531AE switch
EITHER 1 x 10/100/1000 Mbps built-in PHY
OR 1 x 10/100/1000/2500 Mbps MaxLinear GPY211C
- Switch: MediaTek MT7531AE
- WiFi: MediaTek MT7976C
- Button: RST, WPS
**Flash instructions for SPIM-NAND:**
- write *mt7981-rfb-spim-nand-preloader.bin to 'BL2' partition
- write *mt7981-rfb-spim-nand-bl31-uboot.fip to 'FIP' partition
- erase 'ubi' partition
- reset board
- create ubootenv and ubootenv2 UBI volumes in U-Boot
- edit environment and set bootcmd, e.g.
setenv bootconf 'config-1#mt7981-rfb-spim-nand#mt7981-rfb-mxl-2p5g-phy-eth1'
setenv bootcmd 'ubi read $loadaddr fit; bootm $loadaddr#$bootconf'
- load initramfs image via TFTP:
setenv serverip 192.168.1.254
setenv ipaddr 192.168.1.1
setenv bootfile openwrt-mediatek-filogic-mediatek_mt7981-rfb-initramfs.itb
saveenv ; saveenv
tftpboot
bootm $loadaddr#$bootconf
- Now use sysupgrade to write OpenWrt firmware to flash.
SNFI-NAND, SPIM-NOR and eMMC all work very similar, a bootable SD card image
is also being generated. However, as the board I've been provided only comes
with SPIM-NAND all other boot media are untested.

Enable building a factory image which can be flashed through the OEM
firmware's web interface. It seems that the web interface requires a
minimum file size of 10MiB, otherwise it will not accept the image.
The update image is a regular sysupgrade tarball packed in a Netgear
encrypted image. The Netgear encrypted image is the same as used in
WAX202 or WAX206, including the encryption keys and IV.
This adds a script which creates the rootfs_data volume on first
startup. This is required since the OEM firmware's sysupgrade scripts
do not create such a paritition. Note that any script ordered after
70_initramfs_test will not get executed on initramfs. Hence this new
script 75_rootfs_prepare won't create the rootfs_data volume when
using the recovery initramfs.
Also, this deletes the kernel_backup and rootfs_backup volumes in case
we have to create the rootfs_data volumes. This makes sure that
OpenWrt is the actual backup firmware instead of the stock firmware.

Telenor quirks
--------------
The operator specific firmware running on the Telenor branded
ZyXEL EX5700 includes U-Boot modifications affecting the OpenWrt
installation.
Notable changes to U-Boot include
- environment is stored in RAM and reset to defaults when power
cycled
- dual partition scheme with "nomimal" or "rescue" systems, falling
back to "rescue" unless the OS signals success in 3 attempts
- several runtime additions to the device-tree
Some of these modifications have side effects requiring workarounds
- U-Boot modifies /chosen/bootargs in an unsafe manner, and will crash
unless this node exists
- U-Boot verifies that the selected rootfs UBI volume exists, and
refuses to boot if it doesn't. The chosen "rootfs" volume must contain
a squashfs signature even for tftp or initramfs booting.
- U-Boot parses the "factoryparams" UBI volume, setting the "ethaddr"
variable to the label mac. But "factoryparams" does not always
exist. Instead there is a "RIP" volume containing all the factory
data. Copying the "RIP" volume to "factoryparams" will fix this

nanddump -f /tmp/KF.bin /dev/mtd12
```
Then, transfer them to your computer via scp, netcat, tftp
or others and keep them in a safe place.
3. Setup Nvram
Get the current stock: `cat /proc/cmdline`
If you find `firmware=0` or `mtd=ubi`, use these commands:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=1
nvram set flag_last_success=1
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
```
If you find `firmware=1` or `mtd=ubi1`, use these commands:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=0
nvram set flag_last_success=0
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
```
4. Flash stock-initramfs-factory.ubi
If you find `firmware=0` or `mtd=ubi`:
`ubiformat /dev/mtd9 -y -f /tmp/stock-initramfs-factory.ubi`
If you find `firmware=1` or `mtd=ubi1`:
`ubiformat /dev/mtd8 -y -f /tmp/stock-initramfs-factory.ubi`
Then reboot your router, it should boot to the openwrt
initramfs system now.
5. Setup uboot-env
Now it will be setup automatically in upgrade process,
you can skip this step.
If your `fw_setenv` did not work, you need run this command:
`echo "/dev/mtd1 0x0 0x10000 0x20000" > /etc/fw_env.config`
Then setup uboot-env:
```
fw_setenv boot_wait on
fw_setenv uart_en 1
fw_setenv flag_boot_rootfs 0
fw_setenv flag_last_success 1
fw_setenv flag_boot_success 1

```
mtd7: 00040000 00020000 "KF"
mtd8: 02200000 00020000 "ubi_kernel"
mtd9: 04e00000 00020000 "ubi"
```
Run following command:
`ubiformat /dev/mtd8 -y -f /tmp/ubootmod-initramfs-factory.ubi`
Then reboot your router, it should boot to the openwrt initramfs
system now.
2. Check mtd again
```
mtd7: 00040000 00020000 "KF"
mtd8: 07000000 00020000 "ubi"
```
Make sure mtd8 is ubi.
3. Install kmod-mtd-rw
Run command: `opkg update && opkg install kmod-mtd-rw`
Or get it in openwrt server, or build it yourself, then install
it manually
Then run this command:
`insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1`
4. Clean up pstore
Run Command: `rm -f /sys/fs/pstore/*`
5. Format ubi and create new ubootenv volume
```
ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
```
6. (Optional) Add recovery boot feature.
```
ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB
ubiupdatevol /dev/ubi0_2 /tmp/ubootmod-initramfs-recovery.itb
```
7. Flash Openwrt U-Boot
```
mtd write /tmp/ubootmod-preloader.bin BL2
mtd write /tmp/ubootmod-bl31-uboot.fip FIP
```
6. Flash ubootmod-squashfs-sysupgrade.itb
Use shell command:
`sysupgrade -n /tmp/ubootmod-squashfs-sysupgrade.itb`
Or go to luci web.
Now everything is done, Enjoy!
Go Back to stock from Openwrt U-Boot:
1. Force flash ubootmod-initramfs-recovery.itb
Use shell command:
`sysupgrade -F -n /tmp/ubootmod-initramfs-recovery.itb`
Or go to luci web.
Then it should boot to the openwrt initramfs system now.
2. Format ubi and Nvram
```
ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8
mtd erase Nvram
```
3. Install kmod-mtd-rw
Run command: `opkg update && opkg install kmod-mtd-rw`
Or get it in openwrt server, or build it yourself, then install
it manually
Then run this command:
`insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1`
4. Flash stock U-Boot and ubi
```
mtd write /tmp/BL2.bin BL2
mtd write /tmp/FIP.bin FIP
mtd write /tmp/ubi.bin ubi
```
Then reboot your router, waiting it finished rollback in minutes.
Go Back to stock from stock layout Openwrt:
Just run command: `ubiformat /dev/mtd8 -y -f /tmp/ubi.bin`
Then reboot your router, waiting it finished rollback in minutes.

Logic-Level is 3V3. Don't connect VCC to your UART adapter!
Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.
As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.
In case this is not the case, OpenWrt will boot only one time, returning
to the ZyXEL firmware the second boot.
If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.
Installation TFTP / Recovery
----------------------------
This installation routine is especially useful in case of a bricked
device.
Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.
The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.
Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to nwa50axpro-openwrt-initramfs.bin.
$ atnf nwa50axpro-openwrt-initramfs.bin
$ atna 192.168.1.88
$ atns "192.168.1.66; tftpboot; setenv fdt_high 0xffffffffffffffff;
bootm"
Upon booting, set the booted image to the correct slot:
$ zyxel-bootconfig /dev/mtd9 get-status
$ zyxel-bootconfig /dev/mtd9 set-image-status 0 valid
$ zyxel-bootconfig /dev/mtd9 set-active-image 0
Copy the OpenWrt sysupgrade image to the device using scp.
Write the sysupgrade image to NAND using sysupgrade.
$ sysupgrade -n image.bin

The R3 (TX line) and R6 (RX line) are absent on the PCB. You should
solder them or solder the jumpers.
Installation (UART)
-------------------
1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2
2. Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'
3. Load and run OpenWrt initramfs image:
tftpboot initramfs-kernel.bin
bootm
4. Once inside OpenWrt, set / update env variables:
fw_setenv baudrate 115200
fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv fdtcontroladdr 5ffc0e70
fw_setenv ipaddr 192.168.1.1
fw_setenv loadaddr 0x46000000
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)"
fw_setenv netmask 255.255.255.0
fw_setenv serverip 192.168.1.2
fw_setenv stderr serial@11002000
fw_setenv stdin serial@11002000
fw_setenv stdout serial@11002000
fw_setenv tp_boot_idx 0
5. Run 'sysupgrade -n' with the sysupgrade OpenWrt image
Installation (without UART)
---------------------------
1. Login as root via SSH (router IP, port 20001, password - your web
interface password)
2. Open for editing /etc/hotplug.d/iface/65-iptv (e.g., using WinSCP and
SSH settings from the p.1)
3. Add a newline after "#!/bin/sh":
telnetd -l /bin/login.sh
4. Save "65-iptv" file
5. Toggle "IPTV/VLAN Enable" checkbox in the router web interface and
save
6. Make sure that telnetd is running:
netstat -ltunp | grep 23
7. Login via telnet to router IP, port 23 (no username and password are
required)
8 Upload OpenWrt "initramfs-kernel.bin" to the "/tmp" folder of the
router (e.g., using WinSCP and SSH settings from the p.1)
9. Stock busybox doesn't contain ubiupdatevol command. Hence, we need to
download and upload the full version of busybox to the router. For
example, from here:
https://github.com/xerta555/Busybox-Binaries/raw/master/busybox-arm64
Upload busybox-arm64 to the /tmp dir of the router and run:
in the telnet shell:
cd /tmp
chmod a+x busybox-arm64
10. Check "initramfs-kernel.bin" size:
du -h initramfs-kernel.bin
11. Delete old and create new "kernel" volume with appropriate size
(greater than "initramfs-kernel.bin" size):
ubirmvol /dev/ubi0 -N kernel
ubimkvol /dev/ubi0 -n 1 -N kernel -s 9MiB
12. Write OpenWrt "initramfs-kernel.bin" to the flash:
./busybox-arm64 ubiupdatevol /dev/ubi0_1 /tmp/initramfs-kernel.bin
13. u-boot-env can be empty so lets create it (or overwrite it if it
already exists) with the necessary values:
fw_setenv baudrate 115200
fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv fdtcontroladdr 5ffc0e70
fw_setenv ipaddr 192.168.1.1
fw_setenv loadaddr 0x46000000
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)"
fw_setenv netmask 255.255.255.0
fw_setenv serverip 192.168.1.2
fw_setenv stderr serial@11002000
fw_setenv stdin serial@11002000
fw_setenv stdout serial@11002000
fw_setenv tp_boot_idx 0
14. Reboot to OpenWrt initramfs:
reboot
15. Login as root via SSH (IP 192.168.1.1, port 22)
16. Upload OpenWrt sysupgrade.bin image to the /tmp dir of the router
17. Run sysupgrade:
sysupgrade -n /tmp/sysupgrade.bin
Recovery
--------
1. Press Reset button and power on the router
2. Navigate to U-Boot recovery web server (http://192.168.1.1/) and
upload the OEM firmware
Recovery (UART)
---------------
1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2
2. Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'
3. Load and run OpenWrt initramfs image:
tftpboot initramfs-kernel.bin
bootm
4. Do what you need (restore partitions from a backup, install OpenWrt
etc.)
