                      your file is still corrupt. but you can use this its clean and unlocked. make sure to verify after flashing. if it doesn't boot you have problem with your solder or programmer.
                      1st boot, press F2, write service tag, disable Absolute, save, restart. 2nd boot press Alt+F to exit manufacturing mode
