[Q] note 3 keeps on rebooting on both kitkat and lollipop topic

I earlier had an issue where i would get a bootloop at the samsung logo, after several attempts i was able to flash lollipop leak and it runs, but like 5 minutes on it just reboots. i've read numerous threads saying to disable scanning always available, but this does not help at all.

the same thing happens when on safe mode. it reboots about 5-10 minutes in.

any help would be greatly appreciated.
