Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Plenty of success with other models using this patcher but the Lenovo Yoga 12 has me scratching my head...
I successfully dumped and patched a Yoga 12 i5-4200 model, using the 4mb chip (furthest from CPU). However I'm not sure if I mixed up the boards and this one didn't actually have a password. Screen went black entering BIOS, I went through the keypresses anyway, when I flashed back to stock there was no password. Will check again tomorrow as I have one more passworded 4200 here.
The i5-5200 model won't work in autopatcher, file "is corrupted or does not contain a valid dump." Checked with UEFITool, it loads and looks ok.
I tried flashing the patched 4200 file onto the 5200 but it wouldn't boot. Reflashed the 5200 dump, laptop works fine (with password).
BIOS content also seems to change on every reboot, (dump has a different md5sum) but I can always get 2 matching dumps.
Tried again after updating to the latest BIOS (newdump.rar attached) - same issue.
File attached if anyone could take a look please.
