Installation notes

First install from stock firmware: flash the factoryimage through the vendor firmware's upgrade page or recovery mode.
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:
