Re: lumia 1520 reboots
Have you tried performing a soft reset to stop this? You'll need to hold the volume down and power buttons down together for 10-15 seconds or until you feel a vibration. This will factory reset the phone without losing personal data. If you still get boot loops after this you'll need to go to settings>about>reset your phone (but you will lose your personal data if you do this, so make sure you backup first!)
