Resetting/replacing corrupted UEFI Bios?
Recently my surface book downloaded an automatic firmware update which bricked my device. Microsoft are denying responsibilty so I am looking into alternative ways of fixing it (there’s a whole thread about the issue linked here, several others have the exact same issue)
So I have two questions:
- Would it be possible to reset the bios by unplugging the main battery inside? (Similar to removing a cmos battery on a desktop motherboard)
- If the above answer is no, or a reset does not work - which chip contains the bios on the surface book (As I saw there were several flash chips on the teardown guide) and where could I get a suitable replacement?
Thank you in advance!
