Hello !
I had an HP Probook 640 G2 computer that was no longer working (the physical chip bios had failed), so I could not read its contents.
So I retrieved the bios data from an identical model, cleaned the ME region, then programmed a new chip and put it back in my computer where the bios was broken.
The problem is that the information on the bios is that of the computer where I took the information (SN,FeatureByte,BuildId,....). I tried to use HP's DMITool (which I usually use for consumer computers) but I could not write the data to the bios.
When I try to unlock the MPM mode I get the message "HP MPM protocol is not present".
Does anyone know how to change this information? The RethoricalCheese password remover program shows this information, but I couldn't find it with HxD in the BIOS file... maybe it is encrypted?
Thanks for your help!
