Recent samsung devices rebooting a/root cf-auto?

I follow a handful of samsung device threads, tab 3, s6, note 5 etc..., and every one of them have had recent issues that cause the phone to have a reboot that occurs a minute or so after booting up that havent been able to fix with reflashing firmwares or anything related.
My note 5 had to be replaced (no biggie) and others are in the process of doing so as well. A possible fix has been posted by one user but im wondering if possibly the cause is from cf autoroot as it appears that everyone or close to that posted having a similar issue mention cf auto rooting prior.
My steps were flash stock lollipop. Flash stock mm. Cf autoroot stock mm and after that my signal bars or area for were gone completely and the phone rebooted within a minute regardless of airplane mode on or anything else i tried. It did not reboot the same while in recovery stock or custom or download mode as those stayed kn as normal.
I know the warnings and such with cf auto root an whatnot but just wanted to make the observation so that if it is the issue it can be acknowledged before more threads appear with this rebooting issue as it is a PITA.
