Bios Mods -The Best BIOS Update and Modification Source

Hi there,

Would love to pay 100$ bios mod bounty to the person who can whitelist the WWAN Slot of my Lenovo Thinkpad P14s Gen4 AMD.

I dumped the complete BIOS with the CH341A and I think I could also overwrite it directly. Its a Winbond 25Q128JVSQ SPI. Perfectly readable thru the CH341A as far as I can tell.

The goal would be to be able to use the Quectel RM520N-GL.

Thanks a lot in advance

Thanks a lot for your help.

Hi
Are you sure you have this particular chip?
As a rule, in laptops with an AMD processor, the chip is 1.8 volts

Nope I just rechecked and its a Winbond 25Q128JWSQ so I added the 1.8V adapter to the CH341A doing a new dump now :-) but it's not bricked did boot perfectly before :-)

btw. this is the ic chip :-)
