I tried the .bin file, but it doesn't work; only the power button lights up. There are three chips on the board. The main one is 32 MB, the one next to it is 4 MB, and the one next to the display connector is 1 MB. However, the attached file only contained a 16 MB .bin file and an 8 MB .bin file. Could you help me by indicating which chips I need to program and if it's possible to reconstruct the files you sent? I've attached a photo and the backups.

Thank you very much

My question is because the original BIOS is 32MB and the one you sent me to reprogram is 16MB, and there's also another 8MB BIN file that I don't know which chip it corresponds to.
