I updated to Lollipop and wow what a mistake. Today I had to end up going to the Sprint Store. It would keep rebooting on its own constantly. They said I had a corrupt file in the Lollipop update. So they factory reset it and tried getting the Lollipop again. The exact thing happened again, it kept rebooting. so they factory reset it again, wiped it clean and put version 4.4.4 back on the phone and informed me to wait until the next version of lollipop comes out and then update. Guess what???? The phone is still rebooting even after the factory reset. I took approximately 1 hour and 30 minutes for that to happen. Any ideas on what I do now. Please help.
