I need root on my Tab S2 T817R4

Hello anybody knows a root method for a Tab S2 T817R4 LTE please let me know thanks :):)
[Galaxy Tab S2 General] ashyx:
US cellular? Your device is cdma, the boot image for sprint Sm-t817p should work for your device.

Make a twrp backup first just in case.

Hello thanks for your help i tried to install TWRP 5.1.1 T810 but the tablet said "Block by FAP Lock", do you know what is that or which twrp version should i try? , thanks in advance.

---------- Post added at 06:51 AM ---------- Previous post was at 05:58 AM ----------

Disregard the last question, i was able to install TWRP now i'm doing a backup then flash the boot file then super su wish me luck

---------- Post added at 07:07 AM ---------- Previous post was at 06:51 AM ----------

I confirm it works i have root access, used TWRP 5.1.1 T810, then i flashed boot.img for Galaxy Tab S2 Sprint and it did work perfectly,

another thing be sure in developer option to activate OEM unlock if not the ODIN will not install TWRP.

Thank you for your help.:highfive:

Sprint T817P - WORKS GREAT

Thank you. I achieved root, and have LTE on my Sprint T817P

I noticed some people are having issues inspite of the directions by [MENTION=4899305]ashyx[/MENTION] that were quite clear...

It is critical that people extract the boot.img file from the zip and flash JUST the boot.img file with TWRP first BEFORE flashing the SU zip or you will end up in a boot loop.

thank you very much [MENTION=4899305]ashyx[/MENTION] and [MENTION=631273]Chainfire[/MENTION] and anyone else involved. You people are awesome.
[Galaxy Tab S2 General] jazzmachine:
Huge thanks to [MENTION=4899305]ashyx[/MENTION]! I just got my T917T yesterday (5.1.1 AOG8) and just attain root access a few hours ago. It was actually due to this thread that I decided to get the S2... so call up Tmo and get your commission ;):p. Last night a couple of hours after returning home with my new toy a message for a software update popped up. I just immediately dismissed it because I didn't want to risk any problems with the rooting process. However, it just popped up again and this time I actually read the changelog (build AOJ3). The concerning point read, "After updating, you will not be able to downgrade to the old software because of updates to the security policy." I've never actually downgraded firmware, but there are occasionally legit reasons to do so...

Has anyone upgraded to AOJ3 yet? If so, any problems pertaining to root access or otherwise?
[Galaxy Tab S2 General] ashyx:
I seriously would block that update! :o

It's too small to be anything other than a security patch. Its obviously going to replace the bootloader. If they replace it with a locked bootloader say goodbye to root, custom recovery and roms.

The fact that it states you will not be able to downgrade is highly suspicious.
[Galaxy Tab S2 General] jazzmachine:
Agreed. I just wrote a thorough rant in the "Got an update today" thread. They mention "security policy changes" and give an example of one that dictates how I'm "allowed" to use the $$$ device that I own... I'm just not particularly inclined to be stuck on a build that could potentially cause all kinds of problems; waiting ??? for the next update that could fix things, but could quite possibly never come.

Also they mention changes and give an example of something extremely (and confusingly) restrictive, particularly for power users. I wonder what else they've "changed"... I have doubts that it's anything having to do with regular/timely updates, which would be the least they could do if they're putting their users in a spot where they could be stranded on possibly buggy/problematic builds for indeterminate amounts of time (possibly forever!!) :rolleyes:
[Galaxy Tab S2 General] GidiK:
I think it always says that. However, in this case it's true. The "2" in the bootloader version means that you can't downgrade it to the previous "1" version. It sort of works if you don't downgrade the bootloader and modem (I'm talking about experience with the T815 actually).

Some Samsung devices are already at version "3"...
[Galaxy Tab S2 General] typefortytardis:
Update Pushed Nov 11 for Sprint T817P to OJ5

http://support.sprint.com/support/a...pdateTheSoftwareVersionOnYourSamsungGalaxy#!/

I have already rooted with the original software. If I were to update, obviously I'd lose root. Do you think this would be successful for re-rooting? All the update says is "Google Security Patch, Battery Performance Improvements" and no other information.

Sprint unlike t-mobile, at&t and Verizon has never in the past locked Samsung bootloaders (at least with all the Samsung devices I have had - S3,S4, S4 Triband and S5 as well as the Galaxy Tab 4) but idk about the S6 or any newer devices. Should I chance it or wait?
[Galaxy Tab S2 General] graysooner:
Okay. Just restored this tab to stock. Google play movies worked fine. Then redid this root process and Google play movies doesn't work. Did some searching and apparently root sometimes breaks google play movies. However, on my rooted LG G4, no problems. Any ideas?
[Galaxy Tab S2 General] ashyx:
Try root cloaking.
[Galaxy Tab S2 General] stesul411:
Has anyone done the OJ5 update and been able to gain root?
[Galaxy Tab S2 General] typefortytardis:
I'm going to give it a test later tonight or tomorrow. I'll post my results
[Galaxy Tab S2 General] graysooner:
Got root cloak going. I've cloaked everything obviously linked to anything Google. Still no go on play movies. Anything that isn't obvious?
[Galaxy Tab S2 General] ashyx:
Google just doesn't like root.

Pity there isn't a mm release yet or you could have systemless root which even allows android pay.

I tried to get it working on 5.0.2 but couldn't get it fully working.

Might fair better on 5.11.

Only issue is you need to have a stock system partition without root.

Then it's just a case of flashing a modified boot.img then systemless root.
[Galaxy Tab S2 General] graysooner:
Appreciate all you've done. I'll keep an eye out.

Thanks.
[Galaxy Tab S2 General] ashyx:
I was actually offering to make the boot.img mods for you to try. ;)
[Galaxy Tab S2 General] jazzmachine:
Does anyone know of a way to make the sd card writable? I just tried to backup my apps with TB and couldn't do so to the external card. I also tried installing FolderMount, which I use heavily on my Note 4 and after it patched the system, trying to open any app caused an insta-reboot :(
[Galaxy Tab S2 General] typefortytardis:
Apologies for the late post. I have not had a chance to try this method on the OJ5 update released a few days ago,for the Sprint T817P. It has been a long day for me. I shall try to do so Sunday or Monday. When I have done so, I shall post my results.
[Galaxy Tab S2 General] graysooner:
Oh! I would really like to try.

I have stock back on. Am thinking about just getting twrp back and checking the movies before root. Would that make any difference or just be a waste of time?

Edit. Tried it. TWRP alone kills Play Movies.
[Galaxy Tab S2 General] ashyx:
Download the sdcard fix from play.
[Galaxy Tab S2 General] ashyx:
I'm guessing Google is simply detecting the system is modified, I highly doubt Google is aware of twrp.

Go back to stock then ensure that you put a check in the read only box in twrp.

No verizon models not supported. Try kingroot 4.6
[Galaxy Tab S2 General] typefortytardis:
Not going to be able to test this on the new OJ5 released last week as of yet. Even using methods with Xposed, I was unable to trick it into an OTA download, and it has not been pushed to Samsung SmartSwitch yet. Does anyone have any suggestions on how to trick the system status so I can download the OTA update so I can test it on the new OJ5? Or will I just have to wait until it is on Samsung Smart Switch?
[Galaxy Tab S2 General] jazzmachine:
Thanks bud! Just to clarify the app is called SDFix: KitKat Writable MicroSD (it works for Lollipop too).
[Galaxy Tab S2 General] graysooner:
I'm sure you're right. Tried it again. As soon as twrp is flashed, the tab reboots to system and play movies no longer works. But loving the root!
[Galaxy Tab S2 General] Leonarddale:
Rooted and LTE working with good speeds on T-Mobile T817T ... Thank you !
[Galaxy Tab S2 General] BluDever:
Those of you with the T817T and has done this. have any of yall tried Private Mode after twrp/rooting and does it still work?
[Galaxy Tab S2 General] graysooner:
I don't use private mode, but I would be willing to test for you. Just give me something specific to try.
[Galaxy Tab S2 General] BluDever:
Thanks.

just see if it works or not. if it doesn't work, when you try to open private mode, it'll give an error. if you never used it before it'll first ask you to set up a password. once you do that, close out of private mode (if it opened it up for you), reboot the phone, then "log" back into private mode again to see if it'll error out or if it will let you access it.
[Galaxy Tab S2 General] graysooner:
OK. Like I said. Specific, please. Is private mode "Content lock" under Settings-Security? Two finger swipe down does not want to work.

---------- Post added at 11:13 PM ---------- Previous post was at 11:02 PM ----------

Opened up. Asked for pw setup. Accepted and asked for verification. Worked. I rebooted and went back to the above settings menu. Phone asked for pw, entered it and it went to a screen that said "Set lock" or on another line "Backup account". Sorry for my ignorance, let me know if I can do any more damage!
[Galaxy Tab S2 General] BluDever:
Ah hehe sorry :)

Main system settings menu -:> Privacy -> click Private Mode -> Turn switch to "On", select lock type, enter password. Then the switch should show as "On". Reboot, then go back into private mode, turn it on and try entering your password. It should turn on, you can access private mode using "My Files", from there under "local Storage" it should have a folder labeled "Private". If that's there, the you know it worked for sure. OR, if it doesn't work, it'll either error out after you enter your password, or it won't turn it on, or that private folder won't appear in "my files". :)

You may also have a Private mode switch in the notification panel, you can turn private mode on/off from there too.
[Galaxy Tab S2 General] graysooner:
All looks ok, I think.
[Galaxy Tab S2 General] graysooner:
Just be sure to do a backup!
[Galaxy Tab S2 General] BluDever:
awesome. Thanks for checking :)
[Galaxy Tab S2 General] tegezee:
Does anyone have SM-t817P OJ5 file? I'm soft bricked right now & need the new tar file

Thanks in advance
[Galaxy Tab S2 General] tegezee:
This should definitely be in the development section. This is confirmed to work on the latest OJ5 update on the T817P (sprint model).

Just extract the boot.img from the zip file.

Then put the IMG on the the SD, internal or otg.

Flash the img in recovery (twrp "flash img" button)

Then just flash the supersu zip

Hey does this method for rooting and installing twrp work on the at&t variant. ??

It's my first time doing this stuff on a tablet . I have the nexus 6p and it's really easy on that.
[Galaxy Tab S2 General] ashyx:
No so don't try it. Your only option is kingroot.
[Galaxy Tab S2 General] cracjackson:
Okay thanks man. And what about a custom recovery?
[Galaxy Tab S2 General] ashyx:
No, but you can use Flashfire with root.
[Galaxy Tab S2 General] cracjackson:
Really okay man thanks I appreciate it
[Galaxy Tab S2 General] jazzmachine:
Hey [MENTION=4899305]ashyx[/MENTION], I'm not sure if it was in this thread or elsewhere but I recall you saying somewhat recently that T-mobile had not yet released the kernel source code for the 817T? For those unaware, the GPL requires that this happens on day 1!) upon release! Out of all of the sickening shenanigans that the Billion dollar corporate carriers pull, habitual copyleft noncompliance is... up there. I feel that I need to do what little I can, which in this case is unfortunately just filing a report with the FSF: https://www.gnu.org/licenses/gpl-faq.html#ReportingViolation I'm going to look more into it myself but I was just curious about your experience: when/who you communicated with or any other info you feel like sharing... Appreciate it bud! :good:

[Galaxy Tab S2 General] quack-the-doc:
has anyone installed SM-T817T ROM on SM-T817W? Trying to enable AWS frequencies on SM-T817W
[Galaxy Tab S2 General] Jdiel316:
Hi all,

Update: SM-T817W works with twrp_2.8.7.1_LL_5.1.1_t810 from other thread. Recovery mode works great--in Odin set it to NOT reset, then from the download screen on the tablet, hold Power/Volume Up&Down/Home, and when it resets, let go of Volume Down, and you will be in recovery. I backed up the stock stuff with TWRP, reset (re-did TWRP with ODIN) and flashed the boot.img provided for 817T/W on post 1, and then the SU BETA file, and rebooted. I am now CONFIRMED rooted on SM-T817W with functioning LTE! Knox is tripped, but that's okay.

Again, I am on Rogers Canadian SM-T817W, 5.1.1
[Galaxy Tab S2 General] ksimpsonel:
Does the boot.img trip knox or does the twrp trip knox?
[Galaxy Tab S2 General] ashyx:
Both
[Galaxy Tab S2 General] ksimpsonel:
That's what I figured thanks.
[Galaxy Tab S2 General] Nellyboy555:
Def works on the SM-T817T, we just need a rom now lol
[Galaxy Tab S2 General] InsayneShane:
OMG you're a freakin genious! Thank you! this just worked for me. Finally somebody else in Canada on Rogers with this tablet lol

What do you think of the Tab S2?
[Galaxy Tab S2 General] Jdiel316:
Haha :) Much obliged. I'm loving the S2 so far, friend, its a wonderful machine; after getting rid of all the extra crap that Rogers puts on (NHL app....blah) it runs super smoothly. I bought a bluetooth keyboard/case set from Amazon for like $40 and I adore the quick functionality. I think this is going to become my main machine for emails, web surfing, and for sure games like Baldurs Gate. My laptop is a semi-gaming setup, so its too heavy to quick grab and sit on the couch with, so I'm incredibly with the tablet.

Cheers,

James
[Galaxy Tab S2 General] justinuyasha:
I am having literally this exact issue. A friend of mine was given this tablet for free because they messed it up while trying to flash this. They said they flashed the .zip from the first posts and got bootlooped so they were told to wipe the tablet and reinstall stock. They wiped everything just as this guy did, including the backup he made and didn't put on an external storage. Now he's trying to pay me to fix this darn thing and I'm running into these issues. He says he's pretty sure he ticked every option in the Advanced Wipe in TWRP. Odin refuses to install stock firmware, always fails at boot.img. Everything else seemed to flash just fine. I can swap between stock and TWRP recovery. Boot.img from original posts flashes fine but there's no OS on the tablet and I cannot get any OS to flash using odin or TWRP. Any ideas??
[Galaxy Tab S2 General] ashyx:
Why would anyone delete their backup instead of just restoring it?

This is the reason why I can't say enough times or LOUD enough to ALWAYS make a backup in case something goes wrong.

ALSO IN CASE ANY ONE ELSE READS THIS:

IF ANY ONE TELLS YOU TO WIPE ANYTHING OTHER THAN THE DATA PARTION THEN IGNORE IT!

IN ONLY EXTREME CASES WOULD YOU EVERY NEED TO WIPE ANYTHING ELSE OTHER THAN DATA.

It is also apparent people are still NOT following the instructions exactly, this is why bootloops are occurring.

THE BOOT.IMG MUST BE *EXTRACTED* FROM THE ZIP AND FLASHED FIRST!
[Galaxy Tab S2 General] justinuyasha:
He says the person that gave it to him flashed it before the main post was updated. I have no idea why he wiped instead of restoring. If there's nothing to do about it, then I'll tell him I can't do it. I fixed his phone but his Tablet seems screwed.

All I've attempted to do with it is flash a Stock firmware and I can't get that much. I didn't even know that wiping the tablet would seemingly brick the device, or else I wouldn't have agreed on this fruitless job. I've never known Odin to fail on stock OS. =P

If there's no hope, so be it.
[Galaxy Tab S2 General] ksimpsonel:
Your problem must be that the Tablet was updated and you are trying to put a older version on the tablet. This is why it keeps failing.
[Galaxy Tab S2 General] ashyx:
Just get the correct firmware for the region the device is from and it will flash just fine or flash a custom rom with TWRP. Its far from bricked.
[Galaxy Tab S2 General] justinuyasha:
This is my problem though. Sammobile and other sites I check only have 1 version of the 5.1.1 update from September. I cannot find the latest two updates to see if they work. I have downloaded this update 4 times now. It always fail. I just keep doing it over and over and over expecting something different lol.

I know it will not let me downgrade so that's probably the issue. Unless anyone knows where on earth I can find the latest roms for the device?

I was gonna post the link to sammobile that i was downloading but XDA wont allow me. =P
[Galaxy Tab S2 General] ksimpsonel:
If you have twrp installed all you need is for someone with a backup of boot and system and you be golden.
[Galaxy Tab S2 General] ashyx:
Which partitions are actually failing to flash? You can get away with just flashing boot and system to get a running device.
[Galaxy Tab S2 General] justinuyasha:
I don't know what you mean. I've been trying to flash the whole rom using Odin in the PDA option. Odin says it starts NAND write, moves to boot.img then fails. Always the same. I cannot even find a custom rim for this tablet. Lmfao. Thanka for the responses guy! I appreciate the helpful ideas!
[Galaxy Tab S2 General] ashyx:
Flash the stock firmware again with odin then post a screen shot of the failure, so I can see what fails.
[Galaxy Tab S2 General] justinuyasha:
and this is displayed on the tablet after flash fails. I have to reboot to get Odin to attempt to flash again.

again i cannot add pictures for my error because of XDA rules. -.- I'll inbox them to you if it lets me.
[Galaxy Tab S2 General] ashyx:
Odin is failing at the boot image. I also notice your firmware is revision 2 which probably means you can't downgrade and likely the reason for the failure.

I suggest you download and install 7zip then right click the stock firmware tar file, select open archive in 7zip then drag out the system.img from the folder.

Once it is fully extracted right click the system.img. This time in 7zip select 'add to archive' then select 'tar' and 'store' as the only options.

This will create an odin flashable tar image with just the system.img

Hopefully this will now flash with odin.
[Galaxy Tab S2 General] justinuyasha:
I followed your instructions, pretty straight forward. I already had the whole ROM unzipped to see what all I was dealing with yesterday.

I just added teh system.img to archive as a .tar file. I put it into odin and flashed it in PDA section. Odin just CTD. Just closes out and tablet seems completely unaffected. is that normal?

After a few attempts to flash the system.img Odin will finally start the process but eventually just hang. Tablet's status bar is almost full and the green bar on Odin stopped moving.

Tablet now goes to Smart Switch recovery screen, and Smart Switch won't recognize it of course.
[Galaxy Tab S2 General] ashyx:
You can usually get rid of the recovery screen by reflashing recovery and wiping cache.
[Galaxy Tab S2 General] justinuyasha:
well i was able to get TWRP back on the tablet and able to wipe. Not matter what I do with Odin however, it will not flash the System.tar I made with the stock ROM. It either hangs indefinitely or after some time finally fails. Any other ideas?

It's becoming pretty clear that this thing is bricked. I'm running to a brick wall at every turn, I'm about to throw it away and tell the guy he's SOL.

Now recovery cannot mount /system -.-
[Galaxy Tab S2 General] ashyx:
Just format system to ext4 with twrp that will get it mounted.

Maybe it's time to bypass odin and try for a custom rom.

You may have luck with a custom t805 rom.

If that doesn't work, your final recourse is to ask someone who has the latest update to make a twrp backup of boot and system and then post it.

Can I just confirm you are absolutely sure this device is a sprint model?

Reason I ask is if the above fails then bear with me and I will build a system flashable zip to flash with twrp.
[Galaxy Tab S2 General] justinuyasha:
100% positive it's Sprint model

I will try to find a rom for that version of Tablet and see what luck I have. I've tried formatting, it worked but after attempting to flash the system.img again the /system is not mounted and will not format or fix now. lol

I've got system to mount and no errors while mounting it, formatting it, or wiping Cache now. However, if i try to flash anything with TWRP it keeps telling me /system file or directory does not exist. =\
[Galaxy Tab S2 General] ashyx:
Can you post a screen shot of it, POWER + VOL DOWN in TWRP.

Also save the recovery.log and post that.
[Galaxy Tab S2 General] justinuyasha:
Well I woke up, logged in and looked for the tablet to dumb the logs for you but it's gone. I guess the owner decided to sneak in while I was asleep and take it back. lol oh well

You need to boot into twrp after flashing to make it stick.

Flash again, disable auto-reboot in Odin then manually reboot by holding POWER +VOL DOWN + HOME, as soon as the screen goes blank immediately change to VOL UP whilst still holding the other buttons.
