Boot loop.

Got my Galaxy Tab S2 only a couple days ago. Used it lightly a couple times. I go to use it today and it prompts me for an update, so I updated. After that, endless boot loop. It doesn't even factory reset properly (in the recovery mode it gives me a E:Failed to mount /preload error). It'll go to the O/S once every couple times, give me a GameService has stopped error a couple times, then continue rebooting over and over again. I've tried force stopping GameService (whatever the hell that is). Nothing is working.
