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-octeon-generic-ubnt_edgerouter-lite-squashfs-sysupgrade.tar
