Warning to any new 360 owner !

Right I bought one of the really early xbox 360's (which are known to be very faulty) well one day my green power button just turned red and my xbox wouldn't load anymore (it would be simple for some people, they just send there xbox back because its under warranty, me being an idiot decided to open it up which voids the warranty)

So i needed my 360 repaired so I sent it to GT Electronics http://www.gtelectronics.co.uk/ and my xbox came back working all fine...

I bought Dead Rising and it applied and update to my xbox and after that my 360 just started freezing during game play... Still under warranty with GT Electronics i sent it back to them to repair...

Came back fine and I started doing some online gaming with it and it started freezing during game play again

I think GT Electronics did a sh*t job at repairing it because its always been faulty since... They are now refunding my repair cost and sending my 360 back...

DON'T GET YOUR 360 DONE WITH THEM, THERE A BUNCH OF JOKERS!!!
So now I'm stuck with an xbox 360 that crashes... Does any body know of a place that repairs them and does a damn good job of it?

Thank You...

P.S - Excuse my language im just a little angry about it all now...

I can personally confirm the update problem is now fully fixed. I bit the bullet and tried it on a new console this afternoon with no problems at all.

also for those who got error code 66 with modded firmware there is now a fix as well
