Hi,

I'd like to get my BIOS admin password removed from my Latitude 7420's BIOS. I cannot even boot without the password.

I attached the locked ROM file read from W25Q256JV chip.

Service Tag: 3K2D6M3
Express Service Code: 7743644859
BIOS version: 1.22.0
My motherboard is GDC31 LA-K371P Rev:3.0(A02)

I hope, that I didn't forget any detail.

Thanks in advance.

Regards,
Czompi

1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode.
