Re: HP BIOS unlock tool
Yes, I tried this tool and there is no password anymore, but the functions in bios are not active and I can not now use the boot to upload windows 10 with a pen because all functions in bios are not active, I cannot enter them , maybe the tool did something wrong and these functions are inactive and cannot be entered ??Last edited by kros; 01-26-2022, 05:27 PM.Comment

Re: HP BIOS unlock tool
You can't enter the bios with F10, or your can but all parameters are grayed out, and you can't change any?
Try to restore bios defaults.Last edited by Vesko356; 01-26-2022, 05:44 PM.----------------------------------------------------------------------------------------------------------------------------------------------------------

Re: HP BIOS unlock tool
Hello Mate,
HP ELITEBOOK 830 G5
BIOS: sp136471 (https://ftp.hp.com/pub/softpaq/sp136...0/sp136471.exe)
Version: 01.18.01 Rev.A
Release date: Dec 17, 2021
Windows 11 Pro 21H2
I have added a WWAN as below:
HP lt4211 Gobi 4G Module
but, BIOS showing error 703. So far I understand it has something to do with the whitelist. Please, please, please help.

Re: HP BIOS unlock tool
Is it possible to do a verification of the password data in the BIOS dump? If I load the dump into a hex editor then at which part of the file should I expect to see a password or a cleared password? Are cleared passwords simply marked as 0 at said section of the dump? Essentially what is the algorithm that the tool uses to clear passwords? Knowing this will be helpful in working with dumps from a safety standpoint.Comment

Re: HP BIOS unlock tool
Hello!
I have a HP Probook 650 G4 which sadly has a BIOS administrator password, so I cannot enter BIOS setup. I desoldered the W25Q256 flash from the board, read it (3 times, consistently), modified it via hpunlocker.exe and flashed it back.
System starts up, but it is still asking for an administrator password sadly. Any ideas what I might have done wrong or what I might have missed?
Files attached are original BIOS, modified BIOS, screenshot from system info.
Many thanks in advance!

Re: HP BIOS unlock tool
I have a HP 840 G1 with a BIOS Administrator password and a User password. I downloaded the firmware to a file but after applying the patch and flashing the firmware back, the Administrator password has removed but the user is still there. As such I am only able to login as Guest user. Although the Guest user does not allow me to clear any other users. The tool has not cleared any BIOS users with password. It would be helpful to know what does the tool actually do and is there a way to clear out users as well as their corresponding passwords from the BIOS?Comment

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 got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -

Hello to all of you! I need help with a BIOS file.
The BIOS chip is fried on my Asus F542UN laptop, and I bought a new chip that needs programming. I have a CH341a programmer but I need a .bin BIOS file. On Asus support page the firmware has another extension, .310 and from reading on this forum I understand that that file is not complete BIOS.
So, in short I need the "complete" BIOS .bin file to flash on the new chip. Another issue is that on back of the case the label says F542UN but on the sticker on the motherboard it's X542UN.
