Answer to "How do I attach replacement power button to main board?"Hello guys! I'm having a similar problem with a missing power button on my HTC One Mini; I need to power on the phone to access my data (especially contacts saved onto the phone itself!) (debugging wont work as it wasn't enabled when the power ran out). I'll be checking up on this page, as I have no clue what to do; I hope you can fix your phones and in turn educate me to repairing mine! However - £50 for the circuitry seems steep, is there any other way of changing it?
