Hey, this is great! Even though I had to flash the 32MB chip twice, probably because my soldering skills are not good enough, now it works perfectly! I did not need BCU nor MPM, it just boots with the correct information, even though it told me once that it has to recover the data because of a mismatch.

hoaca388, you are the best, thanks a lot, and also thank you again danito for trying to help!

Would you mind me asking how you produced these files? Have you handcrafted them in a hex editor, or do you have a tool for that?

Hello,
in the meantime I tried to clear VSS2, but the laptop did not boot any more then.
So I reflashed "New folder (2).rar" in 32MB and 16MB chip and now I am again in MPM, but the LAN Port does not work. I get an error in device manager for the Ethernet controller and cannot set the right MAC address in the BCU or in the BIOS.
Does someone have a clue how to make the ethernet LAN port work?
Thank you in advance!

Hey, this is great! A clean BIOS where I can enter the information with the Bios Config Utility!

I now flashed the BIOS, and it boots. Then I entered the information in the Bios Config Utility, but somehow the MAC Address cannot be set. It always stayed at 00-04-80-00-40-00 in the BIOS. Probably because of a defective ME configuration this configuration was not possible. Dumb me, I locked the Manufacturer Programming Mode even though the MAC address does not match. When locking the MPM I entered the MAC Adress in the BIOS so the locking was possible. But on the Information page there is still not a valid MAC address. After locking MPM, I could fix the ME by performing a BIOS update.

But now the LAN port does not work. What can I do? Is there a possibility to unlock MPM again, without having to reprogram both chips? Is the non-working LAN port even caused by a wrong configuration or is this an other error? Is it possible to do this with reprogramming only one chip? Shall I send the content of the 32MB Chip? Will this help?

Will cleaning the VSS2 unlock MPM and help here?

danito, thanks a ton, and for any further help, thank you in advance!

Hello,
I have an EliteBook 840 G6. It had a bios password. Then I tried to read the 32MB BIOS chip, but thereby destroyed the content of this chip.
In the meantime I have unsoldered 32MB and 16MB chip and tried to flash contents available here in the forum, but I did not succeed. The best that had happened was that I had a working laptop, but as soon as I restored the BIOS to factory default configuration the laptop died and never turned on again.
I upload the defective 32MB BIOS and the 16MB chip content with password here.
Would someone mind helping here?
Thank you in advance!
