Hello, I am really hoping someone can help me out. I've read through dozens of threads on how to remove the BIOS password from a 840 G10, but I have not been able to figure out how to replicate your patched dumps. I receive hundreds to thousands of this model and similar models that need unlocked. Can you help explain how you are patching the BIOS dumps to remove the password? I have all the tools, programmers, and average knowledge regarding this.Comment

Yes, I have both tools and familiar with using these. I know how to pull the DMI info with the UEFI Tool, but can't get it to go into MPM. I'm using a xGecu T56 programmer and know how to unlock any Lenovo, Dell, and most HP laptops, but having a difficult time figuring out the HP 840 G10 or newer models. What do I need to do to unlock these models? Thank you for all your help.Comment

Hi all, it seems HP have patched MPM from early 2024 and later bios revisions, not only on the 840 G10 I mention below but several other new EliteBook's. Patching the bios through HxD would allow the laptop to go into MPM mode no problem but this is not possible with new bioses, you will be greeted with a 'The Bios has recovered it's identity data from the embedded controller due to data mismatch'. Is there anyway to downgrade the bios with the password active to allow MPM mode again?
I have attached my original dump and the patched dump which had a 100% success rate before HP patched the bios in new revisions....

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,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hello everyone.
I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make... -
Hi sirs. please help
Dell Inspiron 5775 bios locked "Unlock Setup fail"
After generating the Password Recovery code, I go to the “Security” tab - “Locked Settings” - it says “Unlock Settings? I tried many wrong passwords and it shows an error to unlock settings [ Press any key ].
What I did:
I read the bios dump.
Downloaded the bios update to 1.6.0 from the official Dell website, extracted the dump from it, updated the bios, but the problem persisted. Please help me to solve the problem.... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
