So if I understand properly, based on your instructions, some work-in-progress steps would be:Ġ) L77 uses 1.5MB ME firmware (Entry as HP calls it) whereas L78 uses 5MB (Full)ġ) Keep full SPI backup of current/error_at_bios chip and make sure the dump is proper (use verification methods while reading/writing). Thank you a lot for the instructions jeroenvtec. ( will try to enhance the text incl typo's in the next days) After committing all will be locked again so no worries. I have done that with the fitc.exe tool and set all option to debug/manufacture mode (0xFF) on CPU/BIOS, Manageability Engine (ME) and Gbe LAN and finally I also set Independent firmware recovery enable to TRUE, juist press build, and use the this firmware(in build folder) you the programmer. When done it showed passed succeed with a summery.Īnd WITH a vpro cpu ) it works and no committed state and or me in recovery message. You should get a menu with options, I choose vpro and at disabled.įollow the instructions of the tool, you have to reboot couple of time from the ussb 'harddrive' Plugin in the NbDmiFit-2.10 usb stick ( copy all files to it ) mine was already bootable but not sure if needed because use of uefi.īoot laptop and go into bios to set uefi mode with cms on, safe exit ( don't think users will have this but I had ) In my case I had to flash the correct ME firmware with FWUpdLcl64, ignored the size mismatch, lot of program lines. Reboot.Ĭheck if manufacture mode 2 of 10 message is gone, and only not in committed state is left. Open wndmifit from the 2.10 folder, and fill in the data, press commit, if al ok you can lock the mpm with running the lockmpm batch file.

Place the chip in the laptop and boot, it will turn off and on a couple of times and will complain about serial sku and so on, you have to safe the actual data (serial sku ct and so on) before, it should be also on you’re laptop, but copy paste is more easy. Before write unplug usb and insert it again, -push write. You need a programmer I have bought the ch341a and used v1.18 software.ĪLWAYS safe you’re verified! files and do erase and verify!. Solution is use a fresh bios with a unlocked descriptor*, brand it and done :) i am not a expert it was a training on the job. This is the first time doing this stuff but here we go. So that explains why I had to update the ME AND get size error, but after that all was OK

I later found that: Provides updates for L77 ROM for Entry Management Engine (ME) systems, and L78 ROM for Full Management Engine (ME) systems. Because i get the base (empty ) rom from my supplier with L77 I did some transfer in it to make it L78, that went ok but is not how you should do it, that's is why i get some differences I guess.
