[REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock

by zenius

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

Hello,

HP Omen 15-dh0052nf power-on & bios password

by Nopslide

Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....
