Just a simple reboot to Safe Mode. It’s the same way for One X/X+ or any sense 5.x device.
So what does Safe Mode do?
It disable 3rd party apps installed during that session, and is restored by simply restart it. Very useful in troubleshooting, just to find what’s causing problems.
On HTC One (One X/X+ and so on) you do like this:
- Press Power button on phone with phone unlocked and active.
- On the power menu you longpress Power Off
- Click on Restart, this will make phone reboot into Safe Mode
