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???Comment

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 disabledComment

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...Last edited by mferna14; 10-31-2019, 01:18 PM.Comment

Re: RCUnlocker
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
Sorry if the question isn't in the correct threadAttached FilesComment

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 youAttached FilesComment

My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.
