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-lantiq-xway-buffalo_wbmr-hp-g300h-a-squashfs-sysupgrade.bin
    595309e5e77b4a54e9a1941358b83612b7f9aaf62ff2e90a6497db68b02c73c8  openwrt-25.12.5-lantiq-xway-buffalo_wbmr-hp-g300h-a-squashfs-sysupgrade.bin
