OpenWrt firmware bundle for the Huawei HG255D router, ramips target with the Ralink RT305x SoC family, packed as a 6.12 MB zip. The archive likely holds one or more flashable images and may include notes. The HG255D is commonly reflashed through its bootloader or via TFTP, so read any included instructions before writing. Check the board revision and flash size against the image. Keep the original firmware dump and have a TTL serial adapter ready, since a failed write on such routers usually needs serial recovery.
