thanks very much for the reply mate!!!
but what i meant about microsoft banning people is : dont they need to apply an update on your xbox first to see if your using hacked firmware, or can they detect it anyway without using an update so to speak?cheers again, i think im going to flash mine for sure now. it was just voiding the warranty that put me off and overheating problems, but if theres a chance you can get away with it using that hairdryer technique then its all good i suppose
