Did your T480 plays a „melody“ at startup?
mine does…
is this a normal behavior?
I erased the chip, write the patched file into it, flashrom verifies successfully…
Instert RAM into the machine plug the charger (battery still disconnected)
tamper switch taped down.. start the t480…
This guy just plays a melody, screen stays blank, nothing more happens…
so I switched it off, remove the charger & RAM and verify the chip content again (of course with the file I flashed before)
verification failed…
so I did...Leave a comment:

Eeeerm... I cant edit my Post?
Problem is solved... There were a missing libary..
In case someone get the same fallstone, try: sudo apt install libqt5core5t64 libqt5gui5t64 libqt5widgets5t64
Bios file successfully patched... But not flashed yet.. I will try this later, after a new Bios dump with a detached chip... Just for getting sure... I dont really trust that clip for dumping......Leave a comment:

Yeah.. I tried yesterday using the clamp..
works nice..
I did 4 dumps in series and compare all the 4 dumps using sha256sum, all 4 have the same checksum.. - neat..
so I tried the autopatcher..
after a few tries, setting permissions etc the patcher tell me something like „invalid dump“..
what I’m doing in the wrong way?
im using xubuntu 22.04 - up to date
python version is 3.12.something..
maybe the autopatcher can’t handle special characters or longer filenames?Leave a comment:

Hello guys...
I want to unlock my T480 with supervisor Password..
Just a general question for dumping.. I use the CH341A Programmer.. Did you use the clamp or desolder the whole chip?
Kind regards..Leave a comment:
