HTC One Mini M4 - Boot loop

[ShivP]

Hi,

I am using my brothers HTC One Mini M4 (completely stock, never rooted or custom ROM never flashed etc) as a placeholder for when I get the new phone. However, I was using it earlier and the screen went black and the capacative buttons were flashing on and off. It then restarted and I thought it was just a crash, however now it's turned into a loop. It starts with a vibration, then the screen goes black and I am able to hold the volume down + power button to enter the FASTBOOT menu, which it does for a few seconds before just restarting again. I'm now leaving it to just run out of battery, but does anyone have any ideas how to fix this?

Can you enter recovery? Does the same thing happen when it's charging?

 

[ShivP]

Can't enter recovery. I think the power button decided to die, as it ran out of battery and it won't turn on again now

Leave it to charge overnight and see if it turns on tomorrow morning. not much you can do at the moment if the battery is low.

Agreed, I've had a few moments with totally flat batteries, they need a good charge before they think about turning on again.
