I have been wrestling with this problem on iPhone 4S for more than a week. "Flash is Disabled - The iPhone needs to cool down before you can use the flash." I had transferred the motherboard from one phone to another and still had the fault so presumed it was a fault on the board. Today I realised I had mixed up the front & rear cameras and had transferred the rear camera as well as the board. Tried the rear camera out of another iPhone and bingo - problem solved. All that time & research and it was only a 2 minute job to fix it!!
