Installation notes

Already running OpenWrt or ImmortalWrt: flash the sysupgrade image from LuCI (System → Backup / Flash Firmware) or with the sysupgrade command.
The kernel / initramfs image boots from RAM without writing to flash — useful for a first install or for recovering from a failed flash.

Verify your download against the published checksum before flashing:

$ sha256sum openwrt-25.12.5-ramips-mt7621-xiaomi_mi-router-4a-gigabit-initramfs-kernel.bin
