HTC M8 can only unlock (screen turns on) when first plugged it

[Natasha Slusarczyk]

My phone started going nuts like I was hitting buttons when I wasn't and the voice command thing kept going off and so I turned it off and on again And it still did it. So I tried again and then it worked a little but then the screen went very black but I could still see the menue very faintly to hit restart which it did and then someone just turned off completely and I couldn't do anything to turn it on until I plugged it in. When I did the screen turned on and everything works fine but when I hit the lock button it turns black like it should but when I hit it again to turn the screen on it won't do it and the only way to make it work is to unplug and plug in again to turn the screen on. Also it still is doing some odd random keys every now and then but not as bad.... Please help my last HTC bricked on me and if this one does too....

Did you try to factory reset?

 

[Natasha Slusarczyk]

What's the combo to do that again?

 

[dblazer]

Settings-back and reset-reset all data and hit okay

Make sure to back up your personal data before factory reset like photo and music contacts etc....

Its an HTC M8, right?

So hold it upright in portrait mode, and tap tap firmly on the screen, and it should wake up.
