Hi guys. I've got an update

I bought a new CH341A programmer and I could still not read the chips with the clip. So I desoldered the chips and succeeded in backing up both chips!

The size of the chips are 8 Mb and 16 Mb which seems to be correct. I assume this is the main bios and the backup bios.

I've downloaded a BIOS update from Lenovo for my specific laptop and attempted to extract the BIOS.

Can you please help / guide me on how to update the bios on these chips? The laptop won't start and I'm suspecting a corrupt BIOS.

Hi guys I am trying to flash my Lenovo Yoga Slim Pro 7 14IAH7.

I'm trying to follow the instructions here but I'm not doing too well. I tried searching for LENV and found it in the new BIOS file (from .fd) but I can't find it in the existing BIOS file. It might be corrupted. I'll post both BIOS files here in hopes of somebody being able to help me.

Thanks ...
