hi try

Hi,

unfortunately writing this back to main ROM does not do the trick.

HP Sure Start Recovery detected an unauthorized change to the secure boot keys.
Reboot
The BIOS has recovered its identity from the Embedded Controller due to data mismatch
Reboot
HP Sure Start detected corruption in the Intel Management Engine firmware. Select Continue to complete the full recovery process of Intel Management Engine firmware.
Reboot
Windoze


Best regards,
Johan

read also EC chipset and post it here. And use BCU to read DMI with original bios+EC, you'll need it to write it back.

The EC is in the original archive together with main. Unsure what DMI means but I have now read out the config with BCU using /getconfig.

DMi is data machine ID (serial, built id, sku, etc) you'll find them in file got with BCU. After writing files I provide you (write both main+EC) your laptop will enter in manufacturing program mode (MPM). At 1st boot enter in bios setup (F10) and apply factory defaults. after that let it boot in windows and read again DMI with BCU, open both files and fill empty fields from last file with values got in 1st file, including MAC Adress. Also move * from "Mpm Mode" from Enable to Disable, save file then use BCU to write new file. I use commands "biosconfigutility /get:lock.txt" and " biosconfigutility /set:new.txt " (or whatever you named your files got with BCU, I am using BCU v4.0)
good luck!

Send to you, try

The main file causes NeoProgrammer to crash with the not so useful error message "file not open". The same goes for the EC file from post #70, Unlock.rar.

So I don't have a complete package where both files work.

Is NeoProgrammer 2.2.0.10 not recommended? I just picked one of the mentioned applications from some intro forum post.
