This is probably a hardware failure. I'd recommend opening up an RMA with GTAC.

Ahmed,

Based on experience and the fact that you have already tried to reload EXOS through the bootrom we believe this is a hardware issue. You can try to get into the bootrom and type in "boot 3" to see if the diagnostic partition is still active. If that doesn't work then I confirm what Brandon said.

Looks like a hardware failure. Unable to upgrade from BootROM. Raise a GTAC case to process an RMA
