Re: Dell Latitude 5420 Bios Password 8FC8

Hello, can someone help me remove admin password on this bios?
Dell Lattitude 5420 - LA-K491P Rev 3.0
Thanks in advance!

Sorry for my very late feedback and thanks for your help, I tried this binary but it didn't work unfortunately.

I still have bios password so I can't disable Absolute (greyed out).

Is there another file I can try?
Thank you!

What do you mean by "NOT WORKING"? @lapfix`s file should works fine, I checked it too. If you programmed the chip with the Original BIOS in Post #267 the device works or not?
