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:
    $ sha256sum openwrt-25.12.5-lantiq-xway-netgear_dgn3500-squashfs-factory.img
