Read the rules before posting any bios request - https://www.badcaps.net/forum/troubl...before-posting
The RCUnlocker topic is here -> RCUnlocker https://www.badcaps.net/forum/troubl...locker?t=98539
Quote from post 1:
Usage: Drag and drop .bin file to .exe file.
In case there are problems with unlocking your laptop, write a short description of the issue, upload original file and if possible, _unlocked.bin file aswell. Just crying for help is useless. Keep the topic as clean as possible.

A few questions (please, don't forward me to the particular model topic, nobody answers there)
I have a dump of a working password-protected BIOS. I see that the tool has cleared PowerOnPW and AdminPW, also many symbols spread out in this and one other place. Is there any way to read the password without cleaning? Just to keep the original bios. Because after cleaning it doesn't POST anymore. Or what may help to open it?

Hi all,
I cannot unlock the Bios of an HP EliteBook 840 G1 :
- With RCunlocker I got the error message "missing unlockable content" (However, I operated correctly on the 16 Mb Bios chip - Winbond 25Q16DVSIG - I can also read the serial number of the computer on it).
- With HP-unlocker, I have no error message, but the output _.unlocked.bin file is identical to the original file (same checksum).
I add that I started again several times.
Thanks.

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...
