This is a multitool and unlocker for several series of laptops. Works on Windows. No python etc installing needed, all included in package. Everything is tested by myself but since every laptop is not made equally, there might be edge cases. Always VERIFY your file after reading!!!
Unlocking
HP - ProBook, EliteBook, ZBook (including 32MB models)
Chromebooks from all various manufacturers
Apple - everything older than T2
More to come...
Information display (helps to verify file integrity)
HP - ProBook, EliteBook, ZBook (up to 16MB models for now)
Custom logo removal
HP - ProBook, EliteBook, ZBook (up to 16MB models for now)
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.
You may ask for feature requests, I'll see what I can do.Leave a comment:

There is a possibility to recover from this latest disaster yes, but it will involve more work as you`ll have to fill new DMI info, thats another challenge. When you get the new chip let us know.Leave a comment:

You can choose a different 256 chip from the list or add the chip to the NeoProgrammer support list

Here are some notes if anyone else is a novice like me:
1: For this model RCUnlocker just displayed "Unlock Success"
2: I used the GD25Q127C profile in NEO Programmer as there isn't one for the chip.
3: In NEO-Programmer I had to select all 5 options for write IC - Off-protect, Erase, Blank Check, Write, Verify. Without this selected it would not write.

I have removed the bios attachment, you have already posted it twice in this thread, there is no need to post it again. There IS another chip on the board, and its 32MB, find it,look under the plastic ,look everywhere.look for SOP8 or WSON8 chips .Leave a comment:

You were asked to post both files https://www.badcaps.net/forum/troubl...31#post3546731
You have only posted the main bios, there is another chip , not sure if thats also 32MB or 16MB, but there is one somewhere on the board, maybe on the other side, when you find it post the backup.

I have 3 Elitedesk 800 G6 SFF PC with password locked BIOS.
Product Number (same for all 3): 8YM57AV
Serial Numbers: CZC1239T57
CZC1239T5L
CZC1239T3X
The boards are all the same revision (Cersei Rev A)
There are two chips near the BIOS markings (Images Attached):
8 pin Giga Device 25B127DSIG
16 pin 25B256DFIG
I have a programmer on order, it only has 8 pin test leads.
Can you confirm the 8 pin 25B127DSIG is the chip of interest to RCUnlocker and that the tool works with this model of computer?
Thank you.Last edited by shaggysound; 01-18-2025, 07:49 AM.Leave a comment:

Hello, I am trying to unlock an Elitebook 745 G6 with AMD cpu and dis not succeed si far. I know i missed one step may be, i dis not erase the 16mb chip before reprogramming it.
BUt i am wondering also on the quality of m'y reading because rcunlock works well on my file but doesn't display any information like model and serial number. Is that a potential issue ?
Here is attached m'y dumped file before patching.Leave a comment:

by SMDFleaJust a thread to post clean VSS2 files/dumps in.A clean VSS2 file can, in some cases, fix
the infamous **"Endpoint Security" error message.
Be aware that if you use a clean VSS2 you may need to fill in missing DMI info using HP BCU !
I`ve included some clean files/dumps,offsets and a few scripts to autopatch a few models.
The offsets and file sizes are part of the naming convention i`ve used for the extracted
files.
hoaca388 has made an excellent guide how to extract the VSS2 file and edit/clean it up by
filling everything after...-
