Unfortunately no real change. Power lights up. The fan turns on fully and now the button next to F12 lights up. No picture. No boot. What could be the problem? Before everything worked, only the boot error occurred and the DMI information was incorrect. Now nothing works.

However, I have to admit that before I saw your post, I tried a bios update, but that didn't change anything. I uploaded your file immediately afterwards. Is it possible that the EC chip now also needs to be reloaded?Attached Files

I've already tested this, but the setting is already set to "Lock" so I can only change the asset number. Serial numbers etc. are not taken over.Attached Files

I've read a lot here, but unfortunately I can't get any further. Actually I only had one problem with my BIOS, then unfortunately I destroyed two contacts when unsoldering the main chip, so I haven't found a way to read it yet.
For this reason I bought two new chips. These also work and the notebook is running again, but I have no idea how to activate MPM. Because the DMI information is incorrect and I cannot change it. When booting, the error always appears that there is a problem with the Security Device Unit.
Since I can't get to the data from the main chip or don't know whether it's possible because of the broken contacts, I only have a backup of the original EC available. I have a backup of the new bios, but I don't know if that helps.
I read something about this bin file that you copy onto a USB stick and boot from, but unfortunately this doesn't work. Then I read that you have to set the region to a valid one, but what exactly can I do to move forward?
It's about an HP Elitebook 850 G5. Have already found all the data:
Serial Number : 5CG85179YC
Product Number : 3JX60EA
Description : HP EliteBook 850 G5

You would need to replace VSS region with clean VSS or just unlock mpm. And after that, enter DMI in bios (SN, feature byte, mac address etc). This will get rid of endpoint error.

SMDFlea Ah great thanks so much for the script. Will try it tomorrow. Will the change in the EC bin cause any issues with the security endpoint error? I ran into that issue and wasn't sure what to change in the Main bios to fix that.

Just trying to understand how to use this tool. What is the .bin file. How to generate that .bin file

Works with all with a 32MB EC. Its quicker using a hex editor though.
