Ok so I went to flash the sharp tsop and it wouldn't boot (no video output and no dvd eject). So then i read this thread and unjoined the top. IT BOOTED! So I successfully flashed it with raincoat and the Auf hack (just like i've done on all other xboxes). It said it was fine and the flash was successful. But then i goto boot again and i get the christmas lights of death. So I unjoin the top. Same thing. So i take off the wire on the bottom... same thing.
What should i do? Should i unjoin the bottom jumper also? Its a friends xbox and I need to know how to fix this? I know the bios was good on raincoat cuz i've used it many times before.
