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)
LAN *:f7 factory 0xe000
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
