Yesterday I was on my phone and out of nowhere it began turning off and turning back on, it did this about every 15 seconds and I had no idea how to stop it. It then eventually stopped turning back on and when I tried to turn it on, it just kept showing me the start up thing (color wheel) over and over, and over. I've tried pulling out the battery multiple times, I let it sit overnight with the battery not inside, I even kept it plugged into the computer without the battery and that didn't help either. Is there anyway I could fix it without losing all my things? I have some important things I really need. Thanks in advance.
