I didn't say the details in the OP covers everything, I said it's pretty much all there. It is not the job of the OP to hand hold members through every step, and to put pressure on them to do so is a slap in the face for the efforts they have put in to bring members of this community great modifications for our devices. They would be perfectly within their rights to post a file, with zero support, but they choose to post basic instructions, be grateful! Suggesting a stock ROM was only the case because learning and testing by certain members was not forthcoming, hand holding was expected. It took me (a non-dev) around 30 mins to work out what the issue was, and to find a solution, this provides evidence that this procedure is valid, as it is only a file correction required. (As well as a willingness to search outside of this thread, rather than simply moan when efforts fail)

If you have any complaints regarding any moderators actions, feel free to lodge any concerns by PM to the Moderator Committee Account.

XDA is a community for those willing to learn and contribute towards an end-goal which benefits all. It is not a place for things to be handed out on a silver plate, it is not the place to moan when no effort has been made to research the issue at hand, It is not the place to "make your phone cool".

All are welcome here, but some last longer than others.

Any help pls...?
[Galaxy Tab S2 Android Development] O_G:
I have an 819, and didn't look elsewhere, just followed the instructions in the OP, with the exception of grabbing the official TWRP instead of the one located in this thread. The downside of this procedure is the system is wiped, so you'll have to start from scratch. There probably is alternate methods, but I'm not in a place to be able to comment on those.

Hope it helps:)

Can you post your firmware build that TWRP didn't work on?

The builds were updated a short while ago as Samsung keeps breaking TWRP with new firmware updates.

The official build had stopped working on the new firmware.

Looks like Samsung, yet again, may have broke things with an update.
[Galaxy Tab S2 Android Development] tuxing:
I have a SM-T819Y. For me both your TWRP(downloaded in September) & official gts210velte twrp worked fine even after the September BQI2 update.

Used Odin 3.12.7

Thanks
[Galaxy Tab S2 Android Development] O_G:
Ahh, Samsung up to their usual tricks:D

I'm running firmware version:

Baseband: T819XXU1BQCI

Build: NRD90M. T819XXS2BQG3

Security Patch: 1 July 2017

I used ODIN v3.10.7, higher versions failed.

The official recovery that worked is: twrp-3.1.1-0-gts210velte.img. Here: https://twrp.me/samsung/samsunggalaxytabs297lte2016.html

The version in the OP just hang on the TWRP boot screen when re-boot is forced after the flash procedure. I also used the latest test SU: SR5-SuperSU-v2.82-SR5-20171001224502 (Not particularly relevant, but meh)

Thanks for your work, I hope my findings help:)

I downloaded TWRP for my device ( SMT813 ) from the official website. When I flashed it, it auto rebooted. Then when I tried to enter recovery mode manually, it said software update at first and then No command worth the dead Android.

After holding a few buttons ..I don't know which ones..it went to the stock recovery..Not the TWRP one I flashed via odin..( It even said pass ).

Any suggestions?
[Galaxy Tab S2 Android Development] jhill110:
You should boot directly into twrp after flashing.
[Galaxy Tab S2 Android Development] O_G:
As already said, this is caused by the auto-reboot Odin completes after a successful flash. You need to un-check the auto reboot option before flashing, and then force the tablet into recovery by holding home, up volume and power. Good luck:good:

Any rom available for T719Y? Doesn't seem to any choice tho
[Galaxy Tab S2 Android Development] notoriouspk:
I have a Tab s2 T813

Can I root it without twrp ?
[Galaxy Tab S2 Android Development] VeEuzUKY:
I just bought an LTE S2 8.0, but model is T719C. The "C" variant I guess is for China region (I bought it in Hong Kong) but I assume the hardware is same as the standard T719 model. Can anyone confirm if the Recovery is compatible with the "C" variant? I would hate to brick my Tab the first day I try using it, haha:)

Thanks in advance for the info:)
[Galaxy Tab S2 Android Development] Gandicela:
Mine is the same, Singapore unit, it works. However there are no ROMS around so nothing to play with after.
[Galaxy Tab S2 Android Development] VeEuzUKY:
Thanks a lot for the reply:) Just to make sure, you got it rooted and works well right?

As long as I have recovery and root then I can mod things a little and remove enough bloatware to make the stock ROM suck less. There will never be other ROMs for the T719 series because almost no one bought this model.
[Galaxy Tab S2 Android Development] ashyx:
What do you need a rom for? Once you have root, you can mod to your hearts content.
[Galaxy Tab S2 Android Development] ashyx:
Unfortunately as far as I'm aware there is no OEM unlock on your device, so you are a bit limited.
[Galaxy Tab S2 Android Development] VeEuzUKY:
The last device I had from Samsung was a long time ago, a Tab Pro 8.4. There were no OEM locks at that time. So you achieved root or not and what limitations do you currently have with your T719?

---------- Post added at 02:10 AM ---------- Previous post was at 02:08 AM ----------

By the way, my T719C doesn't have OEM Unlock Setting in the Developer Options, and why should it have? This is a full retail, SIM/CARRIER unlocked unit. It was not sold or customized via any carrier or OEM.. so I think there is natively no need for an OEM Unlock option at all.
[Galaxy Tab S2 Android Development] Gandicela:
Which is what i am doing, Mate. We all have favourites i suppose, and mine is LOS not TouchWiz. But i agree with you. Cheers!

---------- Post added at 12:35 PM ---------- Previous post was at 12:31 PM ----------

Correction, I'm on T719Y
[Galaxy Tab S2 Android Development] ashyx:
I don't own any of the Tab S3 series, I just develop for them.

I suggest you do a little research on what OEM UNLOCK is and why it's needed.

Without it you will struggle to even root your device.
[Galaxy Tab S2 Android Development] ayamgoreng:
I use the one with T719.

It works fine. (except with the weird temperature reading)

Not able to go into recovery Tab S2 8.0 T710

Hi, I was wondering if you can help me figure out what I'm doing wrong. After I flashed recovery via TWRP app (I selected 3.1.0-0 but have also tried 3.1.1-1 and 3.1.1-0), I tried go boot to recovery but the device is stuck on the Samsung Galaxy Tab S2 screen. I've tried to boot recovery both via the reboot option and also by manually turning off the device and then try to go into recovery via vol-up/power/home. Here's some more info:

build: T710XXU2CPD9 (6.0.1)

rooted via SuperSu Free v2.82-SR3

TWRP app ver 1.13 build 26

I've tried this multiple times and with clean firmware installs in between attempts. Let me know if you can help me with this. Thank you.
[Galaxy Tab S2 Android Development] ashyx:
Those versions don't exist in this thread. Where did you download those versions from, the official TWRP server?

[Galaxy Tab S2 Android Development] ashyx:
I only support the TWRP versions in this thread. The versions in this thread should work until Samsung break stuff again.
[Galaxy Tab S2 Android Development] ashyx:
Have you tried the T815 version in the OP?
[Galaxy Tab S2 Android Development] w0rdie:
Yes, it doesnt boot.

Edit - It doesn't bootloop or anything, but with the builds posted it boots to Android but won't boot to recovery. I also tried CF auto-root which posts the red insecure recovery message at boot, but it hangs and won't boot the tablet at all.

Hey guys, I wanted to flash this TWRP on my Galaxy Tab S2 T719Y but, since the day I foolishly updated my tab to 7.0, my tab can no longer be detected by any desktop or laptop (idk why). Does anyone here have an idea about this? Or can someone give me the complete drivers for Tab S2? Please?

Thank you.

Does this work on T719?

Does this work on T719? If so, also does it need custom Rom? Or can stock Rom be used?? Tried before and just kept bootlooping and wiping system automatically..

We'll on stock Samsung from months ago on T819 it works perfectly guess it won't be different for T719 ;)
[Galaxy Tab S2 Android Development] lloydsw:
I've tried three times to root following the OP, but not formatting data. The first time I allowed system modifications when first starting TWRP, and after rooting, got stuck with the tablet only booting into TWRP. Flashed back to stock, tired again, same outcome. On the third try, I didn't allow system modification in TWRP, rooted and tab booted normally, but ended up with a screen saying had to factory reset.

I read through the whole thread & thought you could root w/o formatting the data partition, which I don't mind doing. But....TIBU laughed at me when I tried to run it on an un-rooted tab. So my plan was to root, run TIBU, then format the data partition & restore everything. But I can't get there from here.

Any ideas?
[Galaxy Tab S2 Android Development] GldRush98:
I allowed system modifications and formatted (and flashed the disabler) to get rid of encryption and everything worked.

The only trouble I had was going directly from download mode to recovery. I ended up booting to Android then powering off. Then it was easy to get to recovery. Not sure how twrp wasn't replaced when it booted, but oh well.
[Galaxy Tab S2 Android Development] lloydsw:
Ref post #902...so I decided to go old-school and do an ADB backup , format data and ADB restore. The problem was that after taking 20 minutes to backup, the restore stopped after restoring just a few apps. Since I've never had an unrooted device, just decided to bite the bullet, format the data partition and restart from scratch. After doing that, logged on to my Samsung & Google accounts and everything restored as before, but lost root. Reflashed root & the kernel and all is well! Happy ending!
[Galaxy Tab S2 Android Development] tobbbie:
Just rooted my brandnew SM-T719 with your procedure and advice - THANKS!

small remark:

The androidfilehost comment on the t719 image is referring to the Tab 9.7 not the 8 - may confuse some faint hearted :)
[Galaxy Tab S2 Android Development] ashyx:
Android file host don't have device folders for every device, so it just goes in what's closest.
[Galaxy Tab S2 Android Development] tobbbie:
Ah, didn't realize it is the folder structure - thanks anyway.

CF Autoroot did not work for me at all, so went the TWRP path which worked fine.
[Galaxy Tab S2 Android Development] sprallo:
Hi guys,

I successfully rooted an SM-T813 with cf-auto-root.

Is it still necessary to install no-verity-no-encrypt_ashyx after installing twrp?
[Galaxy Tab S2 Android Development] markfm:
I re-confirmed xposed reboot to recovery goes to the TWRP loop :) (No biggie, reflash TWRP via odin takes care of this, and I did a Nandroid backup just before trying it. )

Back to only using those hardware buttons.
[Galaxy Tab S2 Android Development] roustabout:
'phew! I thought I had a bad TWRP.

Man, this is nice. And there's a ton of development going on - the deciding factor for me when shopping for tablets :)

Thanks to all for their support!
[Galaxy Tab S2 Android Development] markfm:
Any of the software based boot to recovery must be setting something that doesn't get cleared by our special twrp. A minor niggle to have an otherwise full twrp and root ☺
[Galaxy Tab S2 Android Development] cr355:
I have a Samsung SM-T713 and everytime I flash TWRP I see the same fault everyone else does - can't mount the /data partition. I have done all the numerous suggested things, ie reformat, delete etc etc and even flashed the fix from the OP. Although it all works when I have done everything my android device then does something so it then becomes unmountable again after I have loaded back all my apps so when I go into TWRP it won't do a backup as it can't mount /data and I am getting hacked off continually going round in a circle. Is this the way it is as it defeats the whole point of putting on TWRP or am I missing something fundamental ?
[Galaxy Tab S2 Android Development] ashyx:
Post your exact steps in a clear, concise manner and I'll tell you where you're going wrong. ;)
[Galaxy Tab S2 Android Development] jhill110:
Anybody have a T713 QI1 stock boot image?

I can't unroot supersu so magisk won't install.

Need that boot image so I don't have to start from scratch.

Yeah I know... I screwed up. :eek:
[Galaxy Tab S2 Android Development] ashyx:
Just restore your backup of the boot partition.
[Galaxy Tab S2 Android Development] jhill110:
It's on a dead ext HD..... Sigh
[Galaxy Tab S2 Android Development] ashyx:
Supersu actually makes a backup of the boot partition.

You can flash it with twrp and can be found in /data named something like stockboot<sha>.img.gz
[Galaxy Tab S2 Android Development] cr355:
Okies,

I follow the steps given in the first post in this thread - all works well as it says, so I end up with a rooted SM-T713 with the latest TWRP installed. When the device then boots into the OS for the first time it starts to setup system apps etc (green or blue screen can't remember) then restarts and boots up normally. It then loads my apps from the cloud then when that has completed my device is ready to use, if I now go into TWRP the /data is now unmountable and TWRP can't now do a backup. So if I now either reformat /data or wipe it the whole apps reload again as they have been wiped from /data and so on and so forth continually.

Strange thing is I have a Galaxy TAB A with an earlier version of TWRP running Android 6.01 the same as my SM-T713 and that mounts /data no problem.

cheers
[Galaxy Tab S2 Android Development] ashyx:
You seem to have missed several vital steps.

You MUST flash the boot image patch then in the same session FORMAT (not wipe!) the /DATA partition.

Your data partition should now be mountable, reboot to TWRP and your DATA partition should still be mountable and remain so unless the boot image is replaced or patched by another mod.

If you boot the device even once without the patch your device will re-encrypt.

You should follow the instructions in the OP implicitly. Failure to do so will cause your device to re-encrypt.
[Galaxy Tab S2 Android Development] cr355:
hello - above you say flash the boot image 'then' format, in the instructions in the first post it says the opposite . . format then flash - does it not matter ?

as an aside why is it TWRP doesn't save settings ie time zone brightness etc - they seem to revert to default everytime you subsequently enter back into TWRP again
[Galaxy Tab S2 Android Development] ashyx:
As long as you long you flash in the same session it doesn't matter.

Settings will save once you fix the the mounting issue.
[Galaxy Tab S2 Android Development] cr355:
all sorted now thanks a bunch

I am brand new to this tablet from a Nexus 7. I had followed the instructions and was able to root successfully, but the next part, the mount/encryption part, I am obviously doing something wrong, as my device will not boot to android, it will only reboot to TWRP, no matter what choice I select under the Reboot option. Manually turning off using power key and turning back on sends it right back to TWRP. What am I doing wrong? Thanks for any help!!

[Galaxy Tab S2 Android Development] Ollibolli85:
Good morning everybody,

can i simply flash the latest version of TWRP from the official TWRP-download-side instead to use the "older" one from the start-thread on a fresh install?

Many thanks in advance!
[Galaxy Tab S2 Android Development] jhill110:
Sure. You can also use the twrp app to install it and help you keep up to date:

https://twrp.me/app/
[Galaxy Tab S2 Android Development] Ollibolli85:
So i can install and use the app on a new, not rootet device?

Is it also always nesessary, to flash the encryption-tool after installing TWRP, even when i root it with Magisk?
[Galaxy Tab S2 Android Development] busdonic:
I've borked this tablet somehow. Was unable to reflash TWRP from within TWRP. I had the file on my SD but was not being recognized. Decided to start fresh and flashed back a stock image, but now unable to get into settings to enable OEM unlock (keeps force closing, no matter what I do), which means Odin doesn't work. Since Odin doesn't work, can't really do anything--can't reflash a stock image, can't install TWRP.

I really apologize, but I'm unsure what do to next. Any suggestions? Thanks much!

**Edit--got it working**
[Galaxy Tab S2 Android Development] jhill110:
No, it needs root to install twrp. Odin it.

People here have said you need to flash the patch but I never do when flashing magisk and it works fine for me.

[Galaxy Tab S2 Android Development] busdonic:
[MENTION=4899305]ashyx[/MENTION]--I apologize if this is the incorrect forum to ask this, figured I would since I'm using the TWRP in this thread, and frankly, your signature of TWRP Jedi gives me hope that you'll know the answer :).

I have a rooted SM-T713 Tab S2, using the steps in this thread. Recently went into TWRP to do a Nandroid backup, which was completely successfully in the backup and a test restore.

However, when I am out of TWRP (i.e. on the tablet itself) and use Solid Explorer to go to the TWRP folder, the backup is not shown. It is shown within the file manager of TWRP only.

Any clue as to what could cause this?

Other helpful bits--I am using your Adoptable storage enabler patch and my Rom is the official LineageOS 14.1 for this tablet.

Thanks for any help, and again, if this is the wrong forum, my apologies.
[Galaxy Tab S2 Android Development] ashyx:
Well it's gonna be one of 2 things.

The file explorer you're using or more likely where you decided to save the backup.

It will be in one of 2 locations.

/sdcard/TWRP/backups

/storage/some-number/TWRP/backups

.
[Galaxy Tab S2 Android Development] busdonic:
I have tried Solid Explorer, ES File Explorer and FX Explorer. All three are showing me the same--nothing. Navigating to /storage/ dropped me back into SD Card.

I have backups saved to SD Card/TWRP/Backups/335ff43c0583907b. Shows as "no content here" in the file explorers, but shows 2 backups from within TWRP.

I'm wondering if it could be the adoptable storage, so I'm going to take everything off of the SD Card, reformat it for external storage and see if that makes a difference. You note that there are some risks when using it on a device that you didn't config it for, and maybe this is one of them. Bottom line tho, is if I need to restore, it IS showing from within TWRP. Thanks ashyx.
[Galaxy Tab S2 Android Development] jhill110:
It would be interesting to see what tapping select storage says when you're looking at the backups in twrp.
[Galaxy Tab S2 Android Development] busdonic:
Before restoring SD Card from the adoptable patch--Select Storage gave these numbers and verbiage:

Internal (12165 MB)

External_SD--adopted storage (0MB)

USB OTG (0MB)

After restoring SD card, so now a separate internal storage and a separate SDCard:

Internal (14475MB)

Micro SDCard (43956MB)

USB OTG (0MB)

Strangely enough, after restoring SD Card and internal memory, the "missing" backups were now visible thru various file managers. I really liked the expanded storage of the merged internal and SD Card, but I guess it had some quirks on the T713.
[Galaxy Tab S2 Android Development] ashyx:
When you enabled adoptable storage did you ensure to use the 'migrate data' function?

It is essential to do this after formatting the SD card as internal.

[MENTION=4899305]ashyx[/MENTION], this is o.o.t but I am struggking with PM:

can you make me twrp flashable stock for t813? how tough is that?

I badly need it... Over t813xxu2bqi1 btu csc. If you need it on fast download, I can send google drive link

thanks
[Galaxy Tab S2 Android Development] ashyx:
I don't understand what you're asking. Can you clarify?
[Galaxy Tab S2 Android Development] ivanox1972:
Of course, thanks for interest

Actually I have t819

But I bricked it, gsm part, by some port custom rom, no matter...

I sent it in service, can't be rapaired. I probably kill efs, it can't boot odin stock. It install without err but can't boot. Just restart when come to boot end.

So, I installed twrp 813, cm 15.1 or any derivative of it. Work perfectly. No reboot. Problem is gsm part for sure...

So I want to have twz rom, my idea is to flash 813 rom...

Would it boot? [MENTION=4899305]ashyx[/MENTION]
[Galaxy Tab S2 Android Development] ashyx:
As far as I remember I built TWRP with system image flashing support. You just need to go to INSTALL and select the system.img you wish to flash.

However I'm not sure it's going to solve your issue as if ODIN still flashes without error then the issue is something else.

If the EFS is corrupt then you can just delete it in TWRP and it will rebuild at boot time. However the IMEI will be set to a default value.

I would advise backing up the EFS before deleting it.

I also advise formatting the system partition using the advanced wipe options and also formatting the data partition using the format Data button then try and install the stock firmware with ODIN.
[Galaxy Tab S2 Android Development] ivanox1972:
[MENTION=4899305]ashyx[/MENTION] can we chat maybe a little hangouts or telegram, would be helpful?

I think you have ideas i jave not tried
