Hi, I rebuilt my own BIOS as per this video: https://youtu.be/wnZ9v2z0ugw, but the admin lock still persisted

I used your "unlock.rar" and it worked flawlessly! ... But how?

I appreciate no good magician ever wants to reveal their tricks, but what did you do exactly?

I love tinkering and its really unfulfilling not understanding how to do the whole process lol...

Thank you so much; Will try flashing it later!

How did you make this file though? Would you mind walking me through the process?

And when I reinstall the chip, what other preparation should I do to the machine? Hard drive disconnected? Is it possible for the BIOS to be rebuilt from the existing data drive?

Thank you!...

Extracted BIN file attached - If this could be unlocked I'd also be very happy! Thanks!...

BIOS password locked Dell Latitude 3440 (Service tag B4HNJX3)
Have extracted the BIN and want to know how to rebuild a clean BIOS

I have come across the 8F8C patcher but not sure if that would work in my case as the service tag ends in 0001.
I tried it and although the log states it patched several mentions of 8F8C in the BIN, I haven't flashed it yet in case such a patch wouldn't work.

Have also tried to extract a clean BIN file from Dell's .exe BIOS updates using 'Dell PFS Extractor', but not confidently; Ended up with a 25MB file instead of the same 32MB...
