How long will it take microsoft to repair my 360?

Should i give my broken Xbox 360 to Gamestop or should i lie to microsoft?

• So I have one of the older 360 versions that I bought after Xbox had been out for 2 months, and it broke down two and a half years ago from an overheat error and the overheat fried some chips and it seems to be beyond repair. I emailed Microsoft but they said I could not send it in because the X-box was opened by my friend when he attempted to fix it and therefore they would not take it. I was wondering if i should just give it to gamestop and see if they would fix it, or if i should message microsoft again but lie and say that i never opened it and just send it in, but if i do that, would they know that the casing had actually been opened? Like I said, I wasn't the one who opened it, my friend was, so I have no idea if there's like a tag or something on the inside that would prove i opened it. Any suggestions?

• Answer:

  Gamestop. If you send it into Microsoft with a broken seal from opening, they'll send it back without fixing it.
