mobile

I am on a T mobile note 3. Have never OTA updated to 5.0. Was running Hyperdrive 7.1 and have the latest Philz recovery. I have flashed the latest AOKP (10-18-14) and latest Gaps (20140901) three times now. Every time I try to play any kind of video, be it in IMBD, play store, you tube, mx player or wherever, the phone instantly reboots. I have been searching for an answer for 2 days now and can find nothing. Any suggestions or input would be greatly appreciated. Thanks
