Frequently asked questions

What should I check before flashing the Huawei HG531 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 4 MB images; the dump size must match your chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
