How to Root Samsung Tab S2 T817T (Step-By-Step Guide)
Obligatory notices
This procedure is only for the Samsung Tab S2 SM-T817T
Performing any of the operations in this post risks bricking your device
Performing any of the operations in this post will irreversibly void your warranty
Performing any of the operations in this post will irreversibly trip Knox and make it unusable for Samsung Pay (and any other features which require Knox)
I am not using a SIM card with my device, so I have no idea how this procedure will impact that functionality. People on the XDA thread (forum.xda-developers.com/tab-s2/help/sm-t817t-root-t3206079) where I pieced together these instructions from suggested that the SIM card still works for mobile data. UPDATE: Later in this thread people have confirmed that mobile data DOES work after rooting. Yay!
Introduction
OK, so a brief story of how/why I was forced to figure this method out. I found a listing on eBay for the Samsung Tab S2 T810N, paid $300 for it and received it into my impatient hands. Without checking the specific version of the tab I push right into the rooting procedure I had thoroughly researched for the T810N. Suddenly my tablet is in a bootloop and I am panicking that it is ruined. In the recovery mode I see that I have the T817T. Anger towards the seller aside, I frantically research how to recover the T817T. There is virtually no documentation for this procedure, so I am forced to mix-and-match. After about 5 hours, the tablet is finally up, running, and rooted!
TL;DR - verify your model number before attempting root
Files
All the files can be found here (drive.google.com/folderview?id=0BxPb6XhrMsaoa01zdjVUVWMzQWs&usp=sharing). Let me explain what each file is:

twrp_2.8.7.1_LL_5.1.1_t810.tar (drive.google.com/file/d/0BxPb6XhrMsaoN0N6V3JzX290aGc/view?usp=sharing) - This is a custom recovery tool for Android. Although designed for the T810 series, it does work on the T817T. Do not untar these files!

BETA-SuperSU-v2.52.zip (drive.google.com/file/d/0BxPb6XhrMsaoNk9uWkxRZ0wwTE0/view?usp=sharing) - A newer version of SuperSu which works on the T817T. Do not unzip these files!
Preparation
Download all the files above. Install, unzip, and untar (or not) as instructed.
Settings -> About device - Verify that you have the SM-T817T
Settings -> About device - Verify that you are running Android 5.1.1
Backup all your files, contacts, apps, etc.
Verify that your device has at least 80% charge
Rooting Procedure
(OPTIONAL) Flash Android 5.1.1 image. This step is not necessarily required. If you are running Android 5.1.1, then you should be fine. However, this is what I had to do, since I got into a bootloop by not checking my version number first (yes, stupid me). Further, if you have any errors or issues below you absolutely will need to perform this step to recover and restart the rooting procedure. Anyway:
Turn off your tablet
Boot into 'download mode' by holding POWER + VOLUME DOWN + HOME. Verify by pressing VOLUME UP
Run program Odin3 v3.10.7.exe
Plug your device to the computer with a USB cable
Verify that Odin message window states "<ID:#/###> Added!!"
Click the "AP" button in Odin and select T817TUVS2AOL1_T817TTMB2AOL1_T817TUVS2AOL1_HOME.tar.md5 file
Press "Start" button and wait for Green "PASS" message to appear. This will take a long time since this is a large file
Your device will automatically reboot
Perform basic setup procedures on Android so that you can access the Settings menu
From this point onward your must perform every step in the exact order as stated. Not doing so seriously risks putting your device into a bootloop or bricking it. You should be able to recover from that, but still...
Enable developer options:
Settings -> About device - click on "Build number" like 10 times until "Developer options" are enabled and button is added to Settings menu
Settings -> Developer options - enable:
Developer options - ON
OEM unlock - ON
USB debugging - ON
Flash TWRP recovery software:
Turn off your tablet
Boot into 'download mode' by holding POWER + VOLUME DOWN + HOME. Verify by pressing VOLUME UP
Run program Odin3 v3.10.7.exe
Plug your device to the computer with a USB cable
Verify that Odin message window states "<ID:#/###> Added!!"
Click the "AP" button in Odin and select twrp_2.8.7.1_LL_5.1.1_t810.tar (drive.google.com/file/d/0BxPb6XhrMsaoN0N6V3JzX290aGc/view?usp=sharing) file
Press "Start" button and wait for Green "PASS" message to appear
Your device will automatically reboot, verify that the tablet boots properly
Copy bootloader and SuperSu to tablet:
With your tablet on, attach it to your computer with a USB cable
Navigate to the root directory of the tablet storage
Copy Tab_S2_t817T_boot.zip (drive.google.com/file/d/0BxPb6XhrMsaob0hyME0zV2EtSnc/view?usp=sharing) and BETA-SuperSU-v2.52.zip (drive.google.com/file/d/0BxPb6XhrMsaoNk9uWkxRZ0wwTE0/view?usp=sharing) files to the root directory
Detach tablet from your computer
Flash custom bootloader with TWRP:
Turn off your tablet
Boot into 'recovery mode' by holding POWER + VOLUME UP + HOME
Select "Install"
Select Tab_S2_t817T_boot.zip and click "Install"
Verify install with slider
STOP HERE!!! READ THE NEXT STEPS CAREFULLY!!!
TWRP will now offer to install SuperSu for you. DON'T DO IT!! Doing this will cause your tablet to bootloop because it is not the right version of SuperSu
Decline the SuperSu installation and restart your tablet
Verify that the tablet boots properly
REPEAT "Flash TWRP recovery software:" instructions. This is a necessary step. Without it your tablet will go into a bootloop and you will need to start the root procedure over. Weird, I know. Just do it.
Flash SuperSu with TWRP:
Turn off your tablet
Boot into 'recovery mode' by holding POWER + VOLUME UP + HOME
Select "Install"
Select BETA-SuperSU-v2.52.zip and click "Install"
Verify install with slider
Reboot the tablet
DONE! Assuming your tablet boots properly your should now be rooted and see the SuperSu app installed on your tablet.
Recovery
If you need to recover from some error you will need to start over completely. Use the Android 5.1.1 image file T817TUVS2AOL1_T817TTMB2AOL1_TMB.zip (same as above) to perform this. You can also use this Android image to restore the device to an unrooted version. This will not restore your warranty or Knox.
Extras
To get rid of the pesky KNOX security notification which will persist, use a program like ROM Toolbox Lite (play.google.com/store/apps/details?id=com.jrummy.liberty.toolbox&hl=en). In the App Manager select the following apps and 'freeze' them:
SecurityLogAgent 4.1.4 (this one is critical to freeze!)
KNOX 2.3.0
KNOX 2.3.1
KNOX II 2.3.0
KNOX SetupWizardClient 2.3.0
KnoxFolderContainer 2.4.0
To get rid of the "No SIM card inserted" notification (if you aren't using a SIM card) use the build.Prop Editor in ROM Toolbox Lite. Add the following entry:
Property Name: ro.config.donot_nosim
Property Value: 1
Conclusions
I put this guide together for people who are having trouble finding a simple and easy-to-follow guide for rooting the T817T. Hopefully this can save you a number of frustrating and worrisome hours (not that rooting your Android device is ever a calm undertaking).
Please let me know if there are any errors in the procedure or if you have any suggestions regarding the steps or presentation of the material. Enjoy being a super-user!

Long time user, first time poster.
First off, let me say, THANK YOU XDA! You guys have been a crazy valuable resource over the years.
However, with regard to the T817T, the documentation is lacking severely. I have created a comprehensive step by step guide to rooting the T817T. Unfortunately, as a first time poster, I cannot post links or anything like that so...if somebody could fix that I would appreciate it. I spent a long time formatting the posting and adding file download links with the XDA formatter so that it wouldn't look like I was link whoring to my blog, just to be told to **** off... . Seeing as that's not possible, here is the url to my blog with the rooting instructions:

Thanks my friend
Edit: Completely professional and well done how to.. written just the way I like it, fantastic!! I think you should just edit your first post and paste all this in here on XDA... and ill be happy to carry your url link for you.

Complete text of the GUIDE
Edited and posted it above. Good luck with the rooting. Thanks!

An excellent guide. I'd spent the last few hours reading post after post gathering the correct information for the T817T specifically. I had come to the same basic conclusion as your guide states but its great to have some confirmation! I have a few differences in my install process than you did though. I did things in this order:
Enable developer options:
Copy bootloader and SuperSu to tablet:
THEN
Flash TWRP recovery software:
and between 6 and 7
Uncheck AutoReboot in the Options tab
7. Press "Start" button and wait for Green "PASS" message to appear
8. Use Power+VolumeDown+Home to reboot from bootloader and AS SOON as the screen goes black slide your finger from VolumeDown to VolumeUp
This should boot you into TWRP
Flash custom bootloader with TWRP:
after 4:
press "add another zip" and select the SuperSU zip as well.
5. Verify install with slider
6. Reboot
Done
By booting directly into TWRP the stock recovery doesn't have a chance to overwrite it. It won't need to be flashed a second time. You can also flash the kernel (...boot.zip) and SuperSU zip in the same pass. Saves a couple steps.
Either way I can confirm this works and all of the files are correct!
Thanks again for organizing all of this and making this great guide!

I'm glad you have figured out another way! This is turning into what a proper thread on rooting should look like
I had actually tried the non-auto-reboot from Odin method too, but couldn't time the change to VOLUME UP correctly. After a couple times I just gave up and tried things the long way around. Never thought to flash the zip files in the same TWRP session though. I generally like doing things the long way around and getting confirmation that things still work after each and every step. Whatever works though!
Thanks for the reply

Indeed it is.
Are your volume buttons functioning properly after this? Just noticed yesterday mine aren't adjusting the volume.

Hmmm, odd. Sorry to hear that. Yes, mine work just fine.

Turns out my volume buttons are fuctioning just fine. I think I just pressed it wrong and didn't have a minute to double check it at the time.

Hmmm. Well that's good to know at least. Thanks for the update!
Also I'm glad you were able to revert to stock and get it working.

Yeah... Ive fully unrooted and gone back to samsung for a bit.. wont be long because I automatically gravitate back to CM. hehe.
vibration doesnt work on CM... that was a big thing because i rely on tactile vibration for notifications.... (i am deaf so.. the noisy parts are useless ?)
but anyway... taking a moment to thank you again for your writeup...i really needed that...soon after i read your blog i was rooted and rocking!
But Samsung sucks bro... i cant stand all these ****ty apps on my tablet so maybe I'll come back sooner.

Yep, I can definitely see why vibration notifications would be important for you!
As much as I dislike bloatware, from any company, Samsung just makes the most powerful tablets/phones. My best solution is to root and disable all the bloatware.
I'm glad the guide was well received and it seems to work for people.

Sorry for the late reply. I Odined the latest firmware to reset everything to a stock base before then flashing as your steps suggest (with the noted exceptions from my first post). My mobile data has worked flawlessly and I have had zero SIM related issues. In fact, I have had no issues what-so-ever. (I did think I had an issue with my volume rocker not working but that was user error. I have my tablet in a case of sorts and was not pressing hard enough). @phduhblog and @androidcues are you both still experiencing mobile data and SIM issues as of now?

Wording changed! Thanks for the update.

One question pls. I have the T817V tab 9.7 w/OEM bootloader option button. Is any of this available to use for my tab? TWRP recovery maybe? Any files? Any reply is appreciated. Novice seeking knowledge. Thank you so much.

Note 4 problems after marshmallow and tmobile update, am trying to root/problems

My note 4 was bought used, no warranty. When I bought it, it was rooted, but no custom rom, worked great. Once lollipop came out, I wiped and returned to non-root and was able to get the update through tmobile. Didn't bother rerooting as things were ok. Marshmallow udpate came, and I noticed a lot of screen lag. Less than a week ago, tmobile did some sort of update and now, the phone shuts off and restarts on it's own, has very slow screen response (nothing, and then tries to do the same function 10 times in a row, messaging is very slow, types the same words several times over). I did a factory re-set twice. Once, I reloaded all my favorite apps, etc. still bad, so then I did factory reset but did not add anything or bring in my contacts, etc. I am planning on buying the note 7 in a 3-4 months, but in the meantime, would like to continue to use my note 4. I tried doing the rooting method using odin, it appeared to work ok (got the successful notice), triggered the knox thing, but..when I use a root checker, it says phone is not rooted. I am hoping that by rooting and putting a new rom on there I can fix this thing in the interim. So..suggestions on what to do next? Let me know what additional information you need. Could it be the phone itself and not the software? Suggestions on a cheap interim phone? links to relevant threads also appreciated. Is there a better way to wipe everything and start new that I am did not do? I did a factory reset. I have two batteries, which I changed out intermittently to see if it as a bad battery. Android version 6.0.1, security patch level july 1, 2016 Kernel 3.10.40-7804088
Knox version 2.6

You need to give more information on what you did to root. What version is your phone, what files did you odin, and did you flash SuperSU?

No to supersu? it's sm N910t, I think what finally worked what odin 3.9 version and flashed the stock that is meant to go with this particular phone to downgrade it down to lollipop. The first few times, I got fail with Odin, but realized that I had marked the option on the phone to keep it from being wiped/flashed if someone found it, once I got that off, I got a successful message. I used the following link and did all of the things mentioned on a link that I am too newbie to be allowed to post, apparently.
but it goes with 3.7 odin, flash the stock firmware from the phone model, and get to the reset button, if successul and then supersu appears.
I got as far as step 8, with odin showing the green 'reset'. But when I went back to the phone, I did not have supersu.
I've tried to do it again, but I get 'fail'

I Think I Trashed my Tab S2 T713

I am coming with hat in hand fully expecting to find out that there is no solution and I am out the $$$ it will cost me to replace. After having this device for close to 2 years, I decided I would root it. I have 5 other devices currently that are rooted and numerous others that I have rooted over the years (including Samsung). Admittedly, I dislike Odin and a lot of other things about rooting Samsung devices. That is part of the reason this was the only device that I ever kept unrooted for more than a month or two. I installed twrp_3.1.0-1_sm-t713_14417n with Odin with no issues. I had SuperSU 2.82 in internal. When I got into TWRP to install it, I saw nothing but directories in internal and it became clear to me that it was encrypted. Attempts to mount, wipe and even reset data all ended up with me booting back to TWRP. I'm sure frustration set in the more things I tried, but now I can't even shut the device down from TWRP or by long pressing power and volume down. Even that just goes back to TWRP. Obviously, I can't get into download mode or system. I just get the recovery booting set warranty bit: recovery message when it starts back up to TWRP. Can't say I have ever seen a device that can't even be forced to shut down, LOL. Thanks in advance if anyone can help.
*I've made some progress. I managed to back door my way into download mode by installing the boot.img from the external SD card. That didn't fix anything, but after that I was able to hold down power down and volume and spam the home button until I got to the download screen. I was able to get back into Odin, but the full firmware file I tried to install errored out at the end with a rev check fail. Hopefully, it was because it thought it was downgrading, so I am downloading the newest file now. The samsung-firware.org D/L is brutally slow. Has a few more hours to go, and I am not positive if it will work yet. Cross your fingers, and throw out any ideas if you have them.

Well, it's alive. Everything is back to normal (except needing to reinstall). Time to root now, LOL!
OK, tried again and ended up restoring the full image again (minus D/L time at least). I am ready to scrap root on this device. I have tried to do everything in the [TWRP 3.1.0-1][ROOT] Galaxy Tab S2(2016) - SM-T713/SM-T719/SM-T813/SM-T819 - 1/4/17 thread. https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627 I would have tried installing no verify, but no matter what I do not see the SU and no verify files on the tablet either after format data without reboot or after rebooting into TWRP. After the format, it shows that data is mounted. Looking at the pictures in the thread, I think maybe it needs the work done on the external SD but the instructions say nothing about that. Time to sleep on it, and maybe someone smarter than me can think of what I might be missing and maybe better step by step instructions are available. At least it is up and running, KNOX trips be damned. I'll post to the TWRP/ROOT thread. BTW, the OS version I am running is XAR-T713XXU2BRB2_T713XAR2BRB2-20180206.

Well, thanks to some middle of the night assistance from ashyx and about 3 hours sleep in the past 48 hours, I am not only restored and working but now rooted with TWRP 3.1.0-1 and Magisk 17.1! Time for a nap.

I am thinking about rooting my T713. Are there better instructions? What did you have to do differently?
I'd like to get it a go, but the instructions aren't as good as for the many devices I've rooted in the past.
Thanks!

The instructions in the TWRP thread are OK, but they could be a little clearer in some places. Take a look at the interaction between ashyx and I towards the end of the TWRP thread.

Samsung S10 Plus - Everytime I restart my phone Magisk would get unrooted. Need help

I am super new to rooting I mainly use it for PokemonGo. I am following this video on YouTube.
Basically when I flashed via Odin, I then install Magisk. Then everything is working and rooted BUT when I restart my phone my Magisk is then magically unrooted (I dont know if this is the right term) it says 'Magisk is not installed' and underneath that is says 'Magisk Manager is up to date'
So why does it keep doing this? Everytime this happens I need to Flash again via Odin and do the whole procedure again. This only happens when I restart the phone. Why does it keep doing this and how do I fix this? I will pay someone who can fix this for me. Ive been trying to figure out for the past day and Im going insane. I have no knowledge about rooting etc like i said i just want to play Pokemongo location spoofing.
Appreciate everyones help.

What did that guide say on how to boot up your device? On devices like yours, that matters...
Here's what the official docs/instructions have on that:

You mean from the guide? Yes, as far as I understand that's the combo that you'd need on an s10 (I don't do Samsung). If you look at John's instructions he's covered that prety well.
Are you sure that you are doing the button combo properly? Because if you don't you'll just end up with Magisk not loading during boot and the system will seem to be unrooted.
But, as I wrote above I don't do Samsung so I'm not the best person to give advice about this... You might be better of asking for advice in your devices forum (because there you'll find people who knows the ins and outs):

Struggling to root SM-G780G

Hi All. First post so please be gentle.
After searching and googlingfor a long time, i have tried a few ways to root my S20 FE (4G).
I have tried KingRoot, no success.
I have tried going down the flashing route, but I am greeted with 'Only official can be flashed (recovery) and (vbmeta) - i have tried flashing the vbmeta disabled.... I also tried using Magisk to create a modified AL file and then flashing it back, but that gave the same result as above.
I have unlocked the bootloader, made a mess first time, so flashed back to stock. Re-locked and unlocked bootloader again.
I'm hoping there is a simple thing that I have got wrong, or forgotten to do etc.
Searches of google for the error message about official firmware etc. turned up a few results, but they all seemed to be flashing other stuff, which it seems i cannot do.
Any ideas?

I have unlocked the bootloader, made a mess first time, so flashed back to stock. Re-locked and unlocked bootloader again.
I'm hoping there is a simple thing that I have got wrong, or forgotten to do etc.
Searches of google for the error message about official firmware etc. turned up a few results, but they all seemed to be flashing other stuff, which it seems i cannot do.
Any ideas?

there is only one method that is going to work for you, that method is linked above.
the problem with instructions can be when you don't know what they mean and the way they're written assumes you should.
there are many steps and they are all crucial (like unlocking the bootloader first).
if you don't understand what something means paste it here and ask, people will help you.

Thank you. I feel i understood what I was supposed to do in each step, but i still get the only official... message. The lock is showing as 'OFF' on the DL screen, but it still blocks me.

The switch in developer mode MUST be like this (picture), otherwise you cannot flash or root custom roms, custom kernels, etc.

I've read that sometimes you have to wait a few days for it to show up as unlocked finally. also you can't lock a brand new phone instantly, you've got use it a few days too.

rooting is pretty universal at the moment barring a couple OEM specifics. pretty much all Samsung phones root the same way.

thanks you guys, i was able to root, first time the device booted, i got bootloop, but i reseted to factory and boom, rooted and working flawless

I also have this s20fe G780G 4g model I'm from Brazil, make a Tutorial help and...

The "OEM unlock" option I missed first but suddenly, after updates of the pre-installed apps and reboots, I got it.
I haven't tried to root as far and directly on front of my vacation.

Hit a wall trying to unlock BL, enabled in dev options and adb into DL mode but LONG PRESS VOL UP is not working! So there is no way to actually unlock BL!??!!?
WTF?
