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-apm821xx-nand-netgear_wndr4700-device-tree.dtb
    93b312ca0731fb472f3c21fde73fefa760287a1c4e04cd327f7e578bc38aeb52  openwrt-25.12.5-apm821xx-nand-netgear_wndr4700-device-tree.dtb
