Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.

Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 1 MB, 8 MB and 16 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.
