Re: elitebook 850 G7 password
Hi,
I read the chip and used RCUnlocker.
It wiped out an 'NvramActiveRegn' section of about 2075 bytes in the bin file at offset 0x37000.
However, it was not able to detect the device type/name/serial...
Is that still OK? Should I resolder the chip back?
Regards,Comment

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,... -

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.... -
