[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] dandroid7:
For those still trying to gain root access using Kingroot... here is a link to a few different versions of "kingroot", a version of "kinguser" (their version of supersu), and a version of "purify" (their version of a memory manager). If it didn't work easily, it may still work with a bit more trial and error, as it did for me (after losing root yesterday).

Yesterday morning, i woke up to find that I had somehow lost root on my tablet... I tried to re-root using the previous process, and it no longer seemed to work. Soooo, I spent a good chunk of time figuring out how to get root back yesterday. The good news is, I got root back... the process however, was somewhat convoluted.

So I tried to find a step by step reproduce-able way to get root every time - and I was not successful at coming up with an exact process that works every time... I was however able to get rooted every time, but the process seemed to vary a bit each time... so trial and error seems to be the key here. I experimented for hours doing this... gaining root, uninstalling root, and retrying - all in the name of trying to help others figure out how to do it on their device.

So here is the basics of how I achieved root... DISCLAIMER - I TAKE NO RESPONSIBILITY FOR YOU, YOUR ACTIONS, OR THE FUNCTIONALITY OF YOUR DEVICE - BEFORE/DURING/OR AFTER YOU TRYING ANY OF THESE PROCESSES THAT I TRIED. THINGS CAN GO WRONG - YOU CAN END UP WITH PROBLEMS - A BRICKED TABLET, A DIVORCE, A DEAD DOG, OR HIT BY A NUCLEAR BLAST. ANY OF WHICH, I TAKE NO RESPONSIBILITY FOR. IF YOU PUSH THE BUTTONS, ITS YOUR RESPONSIBILITY.

Since there is no factory image for 4.4.2 on our device, proceed with caution... if something goes really wrong, you will have a paperweight. There is no Kies or Odin to save you... Also, my knox warranty void count shows as 1 and custom device status, so if you are worried about that be aware...

1) download all the files in the folder at the link above, extract them from the folder and put all the apk's on your device, but dont install them yet (doesn't matter internal/external memory)

2) Boot into stock recovery and wipe cache. reboot.

3) Install kingroot v4.0.1.237

4) open kingroot and try the rooting process. the device will likely reboot at around 18 to 25% or so... once the device reboots, open kingroot again and let it finish the rooting process. If it works - you should go buy lottery tickets, because you just got really lucky! If it doesn't work, proceed to the next step.

5) Install Purify. Run Purify process. Take notice after running the process - at the top of the app does it say root is achieved?? If not, return to step 4 and try rooting again. If that does not work...

6) Install kinguser. open kinguser, does it say you have root access? If not, try the prompt to repair root access (if it shows up)... if not, return to step 4, and try to root again. If no root, try step 5 again. If not, try step 6 again...

7) If still no root access, uninstall kingroot, and install one of the other versions of kingroot... try all of the above again. If still no root... uninstall all 3 apps and start over at step 2 using a different version of kingroot to start with.

I wish I could say there was a logical rhyme or reason for what works and what doesn't... but there didn't appear to be an exact process that works every time. Fortunately, I was able to get root if I tried long enough and tried different combinations of processes. Periodically clearing the cache from the stock recovery really seemed to help increase my odds of success when things weren't going well.

Occassionally the process landed me in a bootloop at the at&t screen... after holding the power button for an eternity, the device would power off - then I would reboot and it would boot normally.

Additionally, I tried on many occasions to swap "kinguser" with "supersu" using an app call "Super-Sume". Sometimes the process worked, and successfully removed kingroot, kinguser, and purify - while keeping root and installing Supersu... Other times the process removed the kinguser, kingroot, and purify - but I also lost root. I tried both the paid and free versions of Super-Sume, but the free version is the one that seemed to work best.

It's up to you if you want to go through all of this - it was tiresome... but if you really want root, maybe trying something like this might help you - maybe not. I also noticed that kinguser seems to sometimes have root access, sometimes not... so sometimes it was just a matter of opening one of the 3 apps and re-running a process or two and root would be restored... not sure why that happens - which is why i opted to use super-sume to remove kingroot once root was achieved. but we will see if i keep root now... if not, at least I know the process above seemed to work for me.
