    I met the same error as you. Have you fixed it yet?
    When I use a clean ME bios from this forum the laptop works fine (entering bios , writing service tag, ... ) but when I quit manufacturing mode (alt +f) the laptop turns off -dead-

    Same behavior when I tried 2 other cleaned dumps .

          Just flash any bios version here to see which version runs.

                      Try this unlocked file ... Good luck ...

                      Important: Input the Service Tag, save the settings, and then restart and press Alt+F to exit manufacturing mode.

                          Hello, I think this won't work.
                          You should always clean the me region if you want to use it on another notebook.
                          You would also have to change the Windows key because otherwise it always stays the same.
                          It is easier for every new notebook to read the file and perform an unlock.
                          I may be wrong, but that's how I would do it.
                          Best regards

                              As the current one, dump the bios -> submit here for unlock -> program back the unlocked dump to the chip.

                                  Almost everything has been said and shown here on the forum, one just has to have the desire to look for it. This of course requires more reading and persistence to achieve the goal, so to speak the clue is in my signature, "Doctrina est fructus dulcis, radicis amarae" - the roots of education are bitter, but the fruit is sweet. That bitterness applies to the volume of work done, which is never easy and without sacrifice of time, self-discipline, diligence and concentration. Without dedication, the path to education is closed.
