[Q] SM-N900 Random Restarting topic

Hi All,
Hope someone can help me, as the title states I have been getting random reboots with my Exynos Version note 3, SM-N900.
I am currently running 4.4.2.
Here are the problems I receive:

• Constant bootloops. (Can only be solved by doing a battery pull)


• Randomly cuts off (no shut down animation) (Doesn't always come back by pressing power button)


• Around the camera area is warm when it cuts off or is bootlooping, but not so hot that it is burning, it has been hotter while gaming.

I have tried everything,

• Clearing cache.


• Factory Reset.


• Safe Mode.


• Reflashing Rom with Odin.


• Didn't reinstall any of my apps.


• Didn't disable any apps.

Please note that I was rooted when this first occurred. I unrooted and reflashed the rom and it has still been occuring.
Also note I got the firmware from www.sammobile.com, and the reboots never occur while the phone is charging.
Can somebody tell me if this is a hardware issue, or just plain software issue.
I have tried just about everything and I can't seem to find a Jelly Bean rom to test the issue.
Should have Bought the Qualcomm Version:rolleyes:
Any feedback will be appreciated.
Thanks.:confused:
