If you are using mpps either use recovery mode slow and flash ori file or ecu on bench and boot mode pin24 on epprom to ground

ok thanks, i will try it with recovery mode

i think only way is to make it boot mode pin 24 on flash to ground

if it fails to drop into boot mode, than desolder the chip, put it into programmer and flash it.
