Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted

[bermo96]

Flash the original bios back and see if it boots ok. Check that the serial number is correct, it isn`t recognised at lenovo support.

Yes the serial number was hard to read on the label.
But I manage to bypass the supervisor password with this patched BIOS.

HI Team.
I have a ThinkPad X1 Yoga 3rd gen that has a SPV password.
I tried unlocking it with the autopatcher, but after flashing the patched file I only got 3 blonks on the power button.
I flashed the original file, buth same effect.
I would appreciate any advice and help.

Hi, I wanted to replace my WWAN card for one that works with linux, but I'm getting the "unauthorized network card detected..." error at boot. I've already dumped my bios, tried to modify it with UEFI tool and IDA free, but I'm not experienced enough to make it work, laptop wouldn't boot after my mod :p. I reverted back to the original bios and the laptop continues to work fine, albeit with the WWAN lock still in place. I'm attaching the unmodified bios dump here with the hope that someone can help me make it work Thanks in advance.

Hi, The autopatcher won't work for this model/generation (+The Password is stored in the MEC1663)

EDIT: Maybe your MTM is supported after all (it could be the last supported one, and every machine type after it isn't)

[rollemup]

Should I hack the MEC1663 instead then?

What Programmer(s) do you have?

[rollemup]

RT809F with iFix prog

[Sparo]

It can handle that MEC via JTAG I think. But first, try these patched files and See if it lets you clear the Password
(Ofc you need to follow the instructions from Post #'1 of that same AUTO-PATCHER thread)
