elitebook 850 G7 password

[Sebastian Thomas]

There are cases when both BIOS chips must be patched...
Write this main BIOS

Hi Stefan, I was finally succesfull yesterday and experienced something weird but maybe normal. I disassembled the Laptop to reach the 16MB IC on the backside, flashed the unlocked BIOS that I had already and dumped again. However the dumped file still had a password in spite of the unlocked version I had flashed before. Maybe it was my mistake because I didn't blank the IC before I flashed, so I tried that and after everything was blank I could finally flash the unlocked File and double check that it worked. So I learned that its mandatory to wipe the old version at first. Anyways. I also flashed your File to the main IC and now there is no password anymore but a Warning. "There is a problem with the Endpoint Security Controller on this device. Please ask HP for maintenance" Do you have any idea what I can do here? Is it possible to install a new HP Bios in the official way? Thank you until here

[Stefan Steff]

Weird...if you remove only the password from EC the Endpoint Security Controller error must not pop up because the DMI data in both chips are the same...
Write this main BIOS and enter this DMI information:

Hello,
I have an EliteBook 850 G7 with password lock.
Unfortunately I currently only have an adapter for the WSON 8x6 W25Q256JVEN 32MB chip, but not for the WSON 6x5 W25Q128JVPQ 16MB chip.
Is it possible to remove the password by only programming the 32MB chip like it was possible on an EliteBook 850 G8 with the instructions from the "840-G8-Patch.txt" somewhere else in this forum? The instructions from that file does not work in the G7.
I'd prefer instructions how to patch the BIOS file myself, but can also upload this 32MB file.
Thank you in advance!

Hi all,

I have a HP EliteBook G7 with Bios locked.
I've used the RCUnlocker on the 16MB chip, but the password is still there.
I've read the 32MB chip as well, but the RCUnlocker is not recognizing as being the right chip.

Please help to unlock

Here you are mate.
Program only this attached dump, the other (32Mb) leave it as is.

Thanks Stefan, it worked eventually, but after writing the chip the verify step was failing "STATUS REG ERROR at 0001 Buffer Value : 0x02 --- IC value : 0x3F" using T48 programmer. The CH341 didn't highlighted any error so I've put the chip back to MB and seems no issues.

In the end, the RCUnlocker is not supporting this model? What is the workaround?

I don't use RCUnlocker just edit the bin file manually with HxD hexeditor.
