My phone just started rebooting itself out of nowhere. It boots to the Samsung logo, then goes back to the Galaxy Edge logo, without reaching the red VZW screen. If I try to go into recovery by pressing Power+VolUp+Home, it starts to enter it, but then flashes the words "Installing Update" with a little Android with wiggling antennae, then reboots and is still stuck in boot loops. I had this happen once before, but was able to reach recovery and wipe the system cache. Now I can't even do that. Must I run Samsung Kies at this point?
