Don't know if this helps, but I was struck with the 'blue screen of death' and random reboots and kernel panics that a lot of T-Mobile iPhone users were seeing.
When I took my 6 plus into the Genius Bar, the genius told me that he could do a 'special wipe' that they could only do in store that would completely wipe and restore the firmware.
So far, so good! No reboots, phone is not running super hot- everything is good. I had tried reinstalling iOS 8.3 via iTunes to no avail.
