Dell Vostro 15 5501 - bios password

[rediii]

hello,

i tried to delete the bios password via clean 8 mb file and replacing the managment engine with the old one from the locked dump.

now the system reports that it's in the manufactuting mode state. i can't quit this mode with alt-f, it's coming back every restart. tried different dumps (and searched for solutions), but the error remains even though the password is gone. can anyone help please? attached the original files.

Flash this to the 64 chip

1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode
