Re: HP Zbook 17 G5 bios password unlock
Thanks! The third one was more helpful.
RS Unlocker with 16mb dump removed password from BIOS
But it seems that something not good because esc while boot sometimes reboots system sometimes let me enter to the startup menu and I don't know whyLast edited by Barmaley_GMN; 10-10-2023, 12:35 AM.Comment

Re: HP Zbook 17 G5 bios password unlock
Greetings oh BIOS masters. I am requesting help with a bricked Zbook 17 G5. I'm requesting clean BIOS and EC images.
I attempted to remove the BIOS password by flashing the BIOS with directions from another site using a CH341A black and cooked the chip while trying to read it. It's a GD25B256D in a WSON 6x8 socket and was not in the MB when I cooked it. I have no flash image to post because I'm a ham fisted newbie.
After finding this site and reading everything, I purchased a RT809F and new chips (W25Q256JV seem to be equivalent) and tried some bin images from this thread. Flashing was successful, but still getting no boot. It's powering up, fans on full, no video, then shuts down and cycles again. I assume failing POST.
I was able to read the EC using a test probe, but I think I screwed the image read by using the auto detect chip type. It's missing some areas when compared to EC images posted here. The current image on the EC is re-flashed of the corrupted read so I have no original EC image.
Also question: The BIOS battery is underneath the MB and hard to get to. Do I have to pull it to flash the EC? Or to get this whole mess fixed?

Thanks kindly in advance.Comment

Re: HP Zbook 17 G5 bios password unlock
On a side note, the software I downloaded for the RT809F from this link appears to be infected with a trojan. The link comes from a thread here.

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'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

I'm trying to reset my bios without success.
I tried :

Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
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.... -
