ramips: mt7621: add support for Xiaomi Mi Router 4A Gigabit v2
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 [1] http://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/r4av2/miwifi_r4av2_firmware_release_2.30.28.bin Signed-off-by: Dmitry Sokolov <e323w@proton.me>
