Re: BIOS Programmer CH341A

Does anyone have the latest firmware for this BIOS Programmer CH341A.. & why this programmer does not Auto-detect the W25Q64FVIG/W25Q64FVZPIG chips, its detects the closet matching ones. Is it because my firmware is not updated???

Re: BIOS Programmer CH341A

Well, the firmware depends on your motherboard's manufacturer, there's not a one-for-all solution. Anyhow, I had the same problem with the programmer not recognizing the bios chip and solved it by installing the programmer's drivers with driver signature enforcement disabled

Re: BIOS Programmer CH341A

Thank you, Sorry I meant to say the latest Programmer Software (Not firmware) & can you inform me where did you find the latest Programmer's drivers & how did you disable the signature enforcement?? Your help will be appreciated...

Hello friends,

I'm trying to unlock my bios, I lost the password of my HP Probook 440 G5 Laptop. But my problem is when I try to dump my BIOS AsProgrammer gives me two chips options in "Find IC" but my BIOS chip is Winbond 25Q128JVSQ

W25Q128BV (WINBOND)
W25Q128FV (WINBOND)

Wich option should I choose to unlock?
Thank you screenshots below

Re: RCUnlocker

The program "SiberiaProg CH341A v1.45" seems to list chips closer to mine but the text seems to cut out. In any case dumps seem to unlock whatever IC I choose so is it crucial? I'd like someone's input before I try to not kill my bios.

Thank you

Thank you for your reply, so W25Q128JV works for 25Q128JVSQ? It gave me a validation error

Yes.

It gave me a validation error

It's almost always happening when you have a bad contact between the chip and the programmer - clean the chip with alcohol, do not use a clamp...
