Re: THINKPAD L390 password

Thanks @dycc. I wish had been more patient. I tried, as suggested, with a patched dump for a similar machine to mine posted earlier on this thread. It went through the usual procedure (asking for hardware id, press space twice etc, but with the difference that at one stage, a strange character appeared on the screen that had never happened with any other machine I have patched with autopatch. Other than that strange character, everything looked normal and it *appeared* to have worked. Sadly, the board no longer starts. I have restored the original bios (known to be a 100% good dump), but it's no longer responding following the attempted patch. All voltages are good, everything looks good, but no start. I will try with the patched bioses you kindly made specifically for me and see what happens.. Thanks.

What you mean by without success? is the patched file not created, or the whole method failed?
Here's your patched file using autopatcher (0.2).

STEP 1: Flash and replace current BIOS with the generated patch file
STEP 2: Boot the machine

Re: THINKPAD L390 password

Hello,
I use autopatch to generate patched bios but my laptop just makes beep sound "011028" and screen stays black without startup. So I flashed original bios back, then my laptop starts booting with password lock. Could help me how to patch my bios file for remove password?

Re: THINKPAD L390 password

Never mind. I figured it out and unlock the supervisor password. In my case, autopatcher just replaces 2 dxe in bios but it doesn't patch evsa region. So I copied EfiSystemNvDataFvGuid part from dycc's patched file and pasted to my autopatcher patched bios on HeX editor. Then I flashed and rebooted, then Success!!! Thank you so much for your great job. You guys are genius!!!
