Default Random reboots after update

So I installed the latest update for my T520 10.1 (which just added the kids mode) and now my tablet does random reboots all the time. Probably at least once an hour. I am running stock rom with root. I did have the cybertronic kernel installed and thought maybe it was causing the reboots. So I Odin'd back to stock, and am still having reboots. Anyone else experiencing this? (I did clear cache and factory reset)

I have exactly the same problem after the updates T520XXUANF4 (with last CF-Auto-Root)
Ditto after a factory reset ...

I think reboots are kernel security related as my note pro 12.2 was rebooting several times a day after root and removing Knox, now I'm re rooted with Knox and no reboots in over 24 hours.

So I had frozen all the knox files with titanium backup. I went in and unfroze them a couple hours ago. No reboots since. Crossing my fingers that it works.

edit: still lots of reboots, so I chose to go with a custom rom.

Same here on the reboots! My device is no longer rooted after the previous update, which worked great. Only MagazineWidget, WatchOn and Screen Saver are turned off. Since I wasn't planning to root again I can't use Titanium Backup, but I'm assuming that whatever I froze there would show up in Application Manager in the "Turned Off' tab? The Knox application still shows the "download" icon b/c I never installed it.

I checked the Sammobile site, but it looks like it doesn't show U.S. firmware. Anyone know how I can get back to the previous update?

From my reading, I think you can use the firmware for Cellular South on sammobile. Or you can use the one from this link and follow his directions. The firmware is for France, but gives you the option for English language. I have used it several times myself.

Also having random reboots after latest update. I was able to root using the same Chainfire file as I did with the previous firmware.

So after using a custom rom for a few days, I really wanted to go back to the stock rooted rom. Here is my procedure. Maybe some of the steps were unnecessary, but in the end it worked. No more reboots!
I first went into twrp and wiped cache and dalvik cache. Then I did a factory reset. Then used Odin to load the stock rom. Went into stock recovery and did another factory reset. Then went thru the process of installing the updates. After the updates I rooted then did another factory reset and cleared cache. I had a random reboot shortly after that when I was restoring everything on the tablet. . But that was over 7 hours ago. No more reboots!
