SMDFlea I do not have CH programmer yet for flashing. The backup I have is previous BIOS done by the official updater.
Will that work? I have read a about the patch you mentioned. Just want to know if you talking about programmer backup or the normal update backup.

Try to reset your bios backup to factory settings then reflash the bios, and at 1st boot press F10 and RESET BIOS to factory defaults https://www.badcaps.net/forum/troubl...y-bios-patcher

do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
Please point me to tutorials for dumping BIOS and restoring or flashing the unlocked BIOS file received from BIOS request.

Hello,
I am trying to remove the BIOS lock of an HP elitebook 840-G8.
I have all tool & software (CH341A, RCUnlocker, AS-Programmer) available and working.
Since I don't have a suitable soldering station, I try to avoid soldering out the bios chip.
With a Wson-chip adapter, I read out the correct bios chip W25Q128JV on the motherboard, which is tricky.
Nevertheless I managed till now to read out the bios chip 8 times. Unfortinally all bios binaries are different, because of the of different CRC32 on the AS-Programmer. That is not suppriesing me.
Curiously the Unlocker tool works for all the different binaries.
The question is how to find the correct binary? Maybe the security mechanism use only a small memory part of the bios chip and the rest of the memory doesn't matter.
Has somebody experience with the topic, respectively any suggestions?
Br

If your model is newer and not in that list, you need to dump your bios, remove password from dump and reprogram bios with modified dump.
For that you need an SPI programmer like CH341A or Raspberry Pi with Flashrom or any other similar programmer. A soic8 clip is also useful so there wouldn't be a need to unsolder bios IC.
When you have your dump, just drag and drop your file on my HPUnlocker tool and it will create a new file. It will add "_unlocked" to the name of your locked file.
Just program the new file on your bios IC.
This unlocker should work on all Elite, EliteBook, ProBook and maybe some other series HP laptops.
For those of you who need to unlock large amounts of laptops, I recommend adding a registry entry:
Code:Computer\HKEY_CLASSES_ROOT\*\shell\HPUnlocker\command
Code:"C:\*location-of-exe*\HPUnlocker.exe" "%1"
If there are any issues, please do let me know so I can improve this tool.
All Elitebooks, Probooks and zbooks which are up to ninth generation which should be up to year 2018, like 840 G5, are supported. Newer models are not supported (yet atleast).
No Pavilions or other trash is supported
-----------------------------------------------------------------
NEW multitool and unlocker added .
Unlocking
HP - ProBook, EliteBook, ZBook (including 32MB models)
Chromebooks from all various manufacturers
Apple - everything older than T2
More to come...

Finally this BIOS worked, thank you very much.
P.S: It would be wise to keep in mind that under certain circumstances both utilities fail to edit the locked BIOS. Unfortunately i don't know the exact circumstances but i'll keep the locked BIOS stored in case someone wants to run some research.
Thank you again!Last edited by Andreasbest; 04-07-2025, 08:34 AM.
