Dell 5280, broken BIOS (boots only into bios recovery) with password.

[kitor]

Hello,

I have Dell Latitude 5280, device blinks BIOS recovery error. If booted with proper pendrive, boots into recovery but asks for admin password.

Serial is GCDFLH2, since I don't get usual prompt I don't know the "suffix". From dump I assume it is -2A7B. However using password from generator on recovery prompt doesn't seem to work for me (using ctrl+enter for input).

I attached the image, UEFItool definitely complains about checksum issues. Maybe someone is able to fix the image or at least remove the password?

Thank you, indeed this one boots and it is clean (no password).

Though it also lost all machine details - service tag (that I was able to program at first boot) and, from what I can tell - embedded windows licence key.

Is it possible to just fix the checksums somehow, without password removal? If I understand correctly then it should boot successfully in regular mode and I could use master password generator as usual.

Or maybe I am wrong, as I see SLIC table, but in original dump there was key too (starting with RNB4J). Maybe this is enough, as Win10 activated online without any issues?
