Tip: Xperia Z Ultra wont boot, or has frozen

This is a problem that happens regularly on smartphones. Because the Z Ultra doesnt have a battery to pull out, and sometimes holding the power button for 10 seconds does nothing.. we need to locate the reset button. 1. Open the microSD card cover, and locate the little red button. 2. Press and hold this down for 3 seconds. You device will vibrate and turn off. 3. Power it back up 4 (boot into CWM) or allow to reboot done!
