Oh god. Sent that in for repair? What? You got to be kiddin' me!
Sorry, I have no sympathy for this dude.
I would have NEVER sent that thing anywhere. Buying a new replacement would have been the ONLY option for me because it would have been worth it in this case. I bet he wishes he had just bought a new one now. Something like that is gaming memorabilia and should have been treated as such. Repairing 360's is NOT a personal experience. They don't give 2 shits about your precious console. I would have to personally be on hand if I let someone repair something like that.
Sorry dude. You asked for it.
