Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I have successfully patched the BIOS dump and flashed it. Steps 1-7 went smoothly,
I was told "TPM certificate changed. Turn it off." during the process.
@AAAC pointed out that this means that the laptop is unlocked.
After rebooting, the laptop posts, I can press enter to enter the setup, then the laptop beeps 4 times and shows the following messages:
"0271: Check date and time settings
0183: Bad CRC of security settings in EFI variable
Press F1 to enter...

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Thank you so much for your reply, it did strike me as weird that the dump was this small.
This chip was hard to find. It was indeed a 20Q128 instead of a 25Q80
The chip is under the keyboard for lenovo P50 20EQ. You HAVE to take a part the heatsink.
Cheers, you saved my day !...

Oops, I'm new to this, I didn't archive the dump so it wasn't added. Sorry. Here it is.
One dumps permissions and ownership were scrambled, so I fixed them to 755 and one to 644 (default result). The result stays the same

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello, is this thread still active ?
The software says that my dump is corrupted or does not contain a valid dump. I Have quadruple checked it and the checksum is OK.

Re: New Members - please post your introductions here
Hey,
I'm Merlin and I like to spent afternoons swearing at dysfunctional material. When I'm not doing that I'm breaking my linux installs.
Jokes apart, I'm a linux enthusiast and I like to thinker with technology.
I sell chocolate and goat cheese the rest of the time
