T470s BIOS HELP NEEDED =)

[OskarB98]

Hello! I have a T470s (20HF) SN: PC0TR9Y3 with a corrupt BIOS after using a CH341 clip on method when trying to repgrogram corrupt BIOS. The machine power button lights up, fan spins, keyboard backlight starts but nothing else.

I have now desoldered the chip but when trying to repgrogramming it always fails at the ''Verifying'' stage and says ''Chip main memory in disagreement'' or similar.

I have the original .bin file (which I think is corrupt) but also tried with a dump file from the internet, same issue with both.

Could somebody please try to maybe fix the original .bin? =)

Turns out this was just a bad programming software (the included software with CH341 programmer)

I used SiberiaProgrammer software which did solve issue (I used a dump from online so I hope it will work without ME clean)

Ofcourse! =)

I used SiberiaProgrammer V1.45 (04/02/2022) which I downloaded from here (will also attach RAR with file): https://receiverpro.net/ch341a-progr...free-download/

Worked great with my CH341a programmer and seemed to have access to many different SPI chips, in my case a 25L12873F
