M8 won't turn on

Hey guys,
I recently rooted my M8 (literally a couple of days ago) and the process went fine, the phone worked perfectly, until today midway through a session at the gym my phone turned off and refused to turn back on.
I've literally tried everything that I know of, letting the phone charge up, but not even the battery animation appears. Plugged it into my Macbook to have Android File Transfer to tell me to reconnect/restart my device, so it picks something up. Tried to boot it into recovery mode and once again, nothing happened and no response.
Are there any other methods to turn a device on with these responses that could work that anyone knows of, or even to get the laptop to read it through any other method?

Re: M8 won't turn on

Just curious if you have tried holding the power button and volume down button for 10 seconds? Maybe even 20 seconds. This worked on my HTC DROID DNA a few times. Good luck because that's all I got.

Who would have thought it was that simple! It actually worked whilst holding the power down for longer than I already had been. Thanks!

I am glad you got it sorted out, and by the way power + volume up works and is much faster than volume down, at least for me.

Re: M8 won't turn on

You can also hold the power on button along with volume up and volume down at the same time

Glad I could help!! From my past experience with about 8 different phones that trick has always worked on quite a few of my phones that don't have removable battery..

Re: M8 won't turn on

I had an issue once where the screen wouldn't turn on. The phone was still on, though, because I could hear notifications coming in and the sound from taking screenshots, too. I had to use the power+vol down buttons to force power down the phone and then it came back up normally without issue and that hasn't happened since.

This is why I miss having a removable battery.

Had exactly the same problem - HTC M8 One refusing to switch on. In my case LED continued to flash; phone completely unresponsive apart from that. First time this has happened, and was beginning to prepare myself for a Boxing Day visit to the local O2 store (OMG!!). Thank you so much for posting this simple fix - hugely appreciated:)
