UART Serial
[o] TX
[o] GND
[o] RX
[ ] VCC - Do not connect it

MAC addresses as verified by OEM firmware:

use   address   source
LAN   *:c2      factory 0xe000 (label)
WAN   *:c3      factory 0xe006
2g    *:c4      factory 0x0000
5g    *:c5      factory 0x8000

Flashing instructions:

1.Create a simple http server (nginx etc)
2.set uart enable
To enable writing to the console, you must reset to factory settings
Then you see uboot boot, press the keyboard 4 button (enter uboot command line)
If it is not successful, repeat the above operation of restoring the factory settings.
After entering the uboot command line, type:

setenv uart_en 1
saveenv
boot

3.use shell in uart
cd /tmp
wget http://"your_computer_ip:80"/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin
wget http://"your_computer_ip:80"/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin
mtd write openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin kernel1
mtd write openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin rootfs0
nvram set flag_try_sys1_failed=1
