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-mvebu-cortexa9-buffalo_ls220de-squashfs-sysupgrade.bin 8be64beb4ddda8fccdcc79f8f234e6a92244954a220d871e4bf3b9fa70668000 openwrt-25.12.5-mvebu-cortexa9-buffalo_ls220de-squashfs-sysupgrade.bin
