[TWRP 3.0.2-1][ROOT] Galaxy Tab S2(2016) - SM-T713/SM-T719/SM-T813/SM-T819
[Galaxy Tab S2 Android Development] sonjohn1:
Thanks!
[Galaxy Tab S2 Android Development] dxxvi:
adb devices doesn't see my sm-t810 when it's in this recovery but it does when it's in stock rom. I wonder if there's anything I missed.
[Galaxy Tab S2 Android Development] andyroidking:
It's not you... He couldn't get adb to work. I tried many, many other ways too but the best I could get was for it to just recognize the device...
[Galaxy Tab S2 Android Development] grimloktt:
Hello. I read SU was removed from 810 due to boot loops. Am I correct in inferring from that and the rest of the instructions that since I have 810 I should just install TWRP and then install SU?

Thank you ahead of time! :)
[Galaxy Tab S2 Android Development] grimloktt:
Can anyone help out, please?
[Galaxy Tab S2 Android Development] ashyx:
Yes its provided in the OP.
[Galaxy Tab S2 Android Development] grimloktt:
Thank you. Yes it is but not clearly. I figured I'd confirm before facing troubles of bricked device. Thnx!

hi man, i've used Sm-715C, after install Rec and use CM 13.1 i can't boot and stuck on screen :Kernel is not seandroid enforcing when restaring,. any solution for this
[Galaxy Tab S2 Android Development] wirelesskebab:
Hi ashyx,

Thanks for your work, I noticed some devices have "TWRP 3.03", is this a true update? If so, are you currently building TWRP 3.03 for these devices? I know you're probably very busy.

Much appreciated.

(I don't know what changes there are from 3.02 as the TWRP website doesn't have changelog reflecting 3.03, perhaps from the source?)

I am using a SM-T710 with December security update. T710XXU2CPK1_T710XAR2CPL1_HOME.

2016 versions (ie 713 I think) are supported officialy but no love for t710 (2015))
[Galaxy Tab S2 Android Development] PsyberEMT:
I am also having this issue. No matter if I flash from ODIN, FlashFire or recovery, I still appear to be stuck on 3.0.2-0. Trying to upgrade for F2FS support (every time I change the data partition to F2FS it fails).

Any ideas? Running the latest build of LineageOS 7.1.1
[Galaxy Tab S2 Android Development] suhridkhan:
Working great on T817T tmobile version. For some reason I had to flash it twice, that's not a big deal anyways. Just stating it here in case somebody runs into the same issue. On first attempt, after odin flash, the tablet booted to the system, and twrp didn't stick. I am guessing the system restored the stock recovery. On second attempt, after flash the tablet booted directly to twrp, and I flashed SuperSU; and everything is good. :)

btw, I flashed the TWRP_3.0.2-1_sm-t810 file...

Thanks dev for the great work.

MTP doesn't work

I have the same problem on my T810 and I have tried to boot recovery with MTP enabled but MTP still not work.

Is there any solution to this?

thx.
[Galaxy Tab S2 Android Development] ashyx:
Check device manager, make sure it lists your device as an MTP device and not ADB.
[Galaxy Tab S2 Android Development] f870103:
My computer treats it as an MTP device.

[Galaxy Tab S2 Android Development] nostupidthing:
Just wondering why you not making it official Bro?

In addition there is orientation error .when I use aroma Gapps touch work vertically but the screen is landscaping
[Galaxy Tab S2 Android Development] ashyx:
Blame Samsung for using a landscape display in a portrait device.

Also Aroma is known to have issues in recent versions of twrp.
[Galaxy Tab S2 Android Development] ashyx:
Also you ask why I don't make it official?

Becase I don't like TeamWin's convoluted process for getting official support.

I have asked them to make the process simpler to no avail. I have many builds for many devices. It's a hassle I can't be bothered with.

Irrespective of that I would still be the maintainer anyway.

Not only that I would have to remove some of the modifications.
[Galaxy Tab S2 Android Development] NeWONEx:
Thanks for your response. The problem is if there is new update for TWRP you can't get it as soon as possible . You have to wait till someone build and upload it.

Anyway I appreciate your efforts [emoji4]
[Galaxy Tab S2 Android Development] ashyx:
Teamwin don't update that often, they only update the builds when they release a new version, they leave patching to the maintainers.

I endeavour to update my builds where it's worthwhile and have an update on the way for the S2.
[Galaxy Tab S2 Android Development] MSe1969:
Hi, I assume you may have found the solution already meanwhile - if not, this is what you need to do:

The S2 tablet devices with a Lollipop stock OS have a bootloader which can't handle Marshmallow kernels.

What you need to do to overcome this is to get an original Marshmallow Stock ROM (best is to download an unbranded one) for your device, go to download mode and flash this Marshmallow Stock ROM via Odin. This will overwrite everything (including TWRP, but will also replace/update the bootloader). Once finished, boot once into the stock ROM, do your exercise with the developer options again (allow 'OEM unlock', if applicable), go to download mode again, flash TWRP, make sure to boot directly into recovery afterwards and now, you can flash any Marshmallow (or even Nougat) based Custom ROMs.

You will most probably still see the "Kernel is not seandroid enforcing" or "Recovery is not seandroid enforcing" messages, when you boot, but this will not cause a bootloop any longer, so simply ignore those messages.

Regards, M.

UPDATE 14/3/2017 - Updated versions t710 and t715 with new builds.
[Galaxy Tab S2 Android Development] papampi:
Thanks for new builds.

So your builds doesn't support Android 7.x ?

From TWRP 3.1.0 change log :
[Galaxy Tab S2 Android Development] ashyx:
Yes of course, but there is no official nugget firmware yet.
[Galaxy Tab S2 Android Development] f870103:
I've tried the latest build on my SM-T810. And I found two problems.

First, if I use the Power Off option in this build, it does power off, but next time when I press the power button to boot, it will boot to recovery instead of system. I must go to use Reboot System in TWRP .

Second, the MTP function still not work.My computer treats my T810 as an MTP device, but it doesn't show up in My Computer.(Attachment is the screenshot)

P.S. My T810 runs official marshmallow ROM(T810XXU2CPK1).

thx
[Galaxy Tab S2 Android Development] ashyx:
The reboot to recovery after power off has always been like that on Samsung devices, it's just the way it works on Samsung devices.

MTP should be working. Reboot with MTP already enabled then try again.
[Galaxy Tab S2 Android Development] f870103:
I tried to Reboot with MTP enabled for three times and two computers, but I still not found my T810 in My Computer.

P.S. My two computers are both running the latest Windows 10 version 1607.

thx
[Galaxy Tab S2 Android Development] ashyx:
I'll take a look, it was working in previous version?
[Galaxy Tab S2 Android Development] f870103:
No. Both 3.0.2-1 and 3.1.0-1 are not working.

Flashed t710 via TWRP so far so good
[Galaxy Tab S2 Android Development] jxb25:
quick question I have twrp version 2.8.7.1 installed how can I update it without a computer
[Galaxy Tab S2 Android Development] ripee:
Most file manager apps are able to extract .tar files, ie. ES File Explorer will need to download a plug-in, but the concept's the same.

Inside the .tar file is a recovery.img file, which can be flashed in TWRP 2.8.7.1 when you select "Install Image" under the main menu's Install.
[Galaxy Tab S2 Android Development] jxb25:
ok thanks gonna try it
[Galaxy Tab S2 Android Development] NeWONEx:
Actually your build didn't support OTA update from LOS 14.1 . There is something missing . BTW Raymanfx fixed this issue in his build.
[Galaxy Tab S2 Android Development] ashyx:
What do you mean it didn't support? What's the issue and for which device.

Please support t715Y, LTE, exynos version, thank you very much
[Galaxy Tab S2 Android Development] ashyx:
It already does, just flash it.
[Galaxy Tab S2 Android Development] lehongwang:
I did flash many times OK but still enter the original recovery, i'm on 6.0

can you give me the correct link for T715Y

thank you very much
[Galaxy Tab S2 Android Development] ashyx:
Disable auto-reboot and boot to recovery immediately after flashing or twrp will be replaced by stock recovery.
[Galaxy Tab S2 Android Development] lehongwang:
haha, I forgot to uncheck auto reboot but it worked, thank you very much

now Im looking for rooting method for 6.0.1 of t715y

WOw, you are the best

custom recovery and rooted, now Im looking for custom rom / cooked rom of t715y

thank you very much again
[Galaxy Tab S2 Android Development] MSe1969:
Hi ashyx,

thanks for the good work. Two short comments:

1. In the OP section of this thread, you've mentioned "UPDATE 12/3/2016 - New version of TWRP has been released v3.1.0-0" (typo)

2. MTP does not work for me (using Debian 8.7 linux) - device is shown when calling lsusb, but not mounted. I've read in this thread similar posts for other devices. All works well when OS is normally up, but within recovery mode with your TWRP, it doesn't.

Regards, M.
[Galaxy Tab S2 Android Development] ashyx:
What do you mean typo, that is the latest version?

I would need someone on windows to confirm mtp doesn't work. Have you tried rebooting recovery with mtp enabled?
[Galaxy Tab S2 Android Development] MSe1969:
typo: We have 2017, not 2016 (in my post, I have shown the six of 2016 in bold) :)

Yes, I did reboot into recovery with MTP enabled. When I enable/disable MTP within TWRP, the file manager shows the device (if enabled) or does not show it (if disabled), but the contents are not mounted, neither internal storage, nor (external) SD card. The behavior is the same as decribed by f870103 (who uses Windows) for the SM-T810 in this thread.

Regards - M.
[Galaxy Tab S2 Android Development] ashyx:
Ah ok will correct, thanks for pointing out and will have a look at mtp.
[Galaxy Tab S2 Android Development] Deltadroid:
If I have TWRP already installed and want to update my stock ROM to a new version, can I factory reset and then use heimdall to flash all the firmware components (except the recovery) and then let the system boot up normally without losing TWRP? I'm curious if TWRP would still be replaced if I don't reboot directly into the recovery after using heimdall to update the ROM. Then afterwards, reboot back into TWRP to install SuperSU then flash no-verity-no-encrypt_ashyx? I assume that flashing no-verity-no-encryp always needs to be done last, after installing SuperSu.

Edit:

I see now that what I mentioned above will not work because there is still a copy of the stock recovery in /system that will replace TWRP. We must still boot directly into the recovery after updating the system partition.
[Galaxy Tab S2 Android Development] tripLr:
Accidentally flashed the apk! got stuck in bootloop.

Had to Odin the TWRP.

Note to sm-t710 users. The flashed version 3.xx works with Lineageos 14.1 experimental.

However the installed version will not find the sm-t710.

Do not flash super SU with Lineages ! Us the downloads.lineageos.org extras su add on.

So the only bug to report is that. The installed TWRP will not see the device.

Thanks the Devs. Love flashing ROMs now.
[Galaxy Tab S2 Android Development] fre78:
Nougat (stock) is available for SM-T810 since a day and I've flashed it. Works well.

Would it be safe to flash "TWRP 3.1.0-1 for Galaxy Tab S2 T710/T715/T810/T815 models - Lollipop 5.0.2/5.1.1 Marshmallow 6.0.1" from OP ?
[Galaxy Tab S2 Android Development] westernmg:
I am just downloading the nougat ROM and would also like to know this :)

Have you already tested to flash TWRP?

Maybe also Magisk to obtain root?
[Galaxy Tab S2 Android Development] ashyx:
There's no reason why it shouldn't work unless the bootloader doesn't like the kernel, however they are usually backwards compatible as far as recovery is concerned.
[Galaxy Tab S2 Android Development] nostupidthing:
Sometimes when vendor release new firmware custom rom start asking people to update as wellbfor some reasons. Is this the case also for nougat on t8/710?
[Galaxy Tab S2 Android Development] fre78:
Thank you. Just flashed the TWRP 3.1.0-1 file from OP on my sm-t810 with nougat stock firmware, and it works without any problem.
[Galaxy Tab S2 Android Development] juniper1982:
Hello. I just installed the new gts210vewifi twrp recovery via the twrp app.

Unfortunately, when i tried to boot into recovery it is now stuck at the boot logo! I used the twrp app to reboot into recovery. And it was 3.1.1 i installed. I can't turn the tablet off, i cant reboot. The only thing i can do is get it into download mode.

What can be done!
[Galaxy Tab S2 Android Development] ashyx:
The (official) version is not affiliated with the version here and as I don't offer support for it.

The original twrp for the s2 was and is created/maintained by me, the (official) version was built by someone else sometime after.

You would need to contact teamwin or the maintainer of the version you have installed.

You can probably recover by reflashing the stock firmware.

You can flash the version here, but one thing to note is if you are on the nougat update then dm-verity maybe in force causing your device not to boot.

There are 2 ways to deal with this, flash supersu or the boot image patcher after formatting data.
[Galaxy Tab S2 Android Development] juniper1982:
OK. Perhaps this isn't the correct thread.

Unfortunately, I can't seem to connect to the device even in download mode. I am using adb on ubuntu, and while the kernel sees the device, adb does not. If you don't have any suggestions on how to get around this, I will post in the appropriate thread (which is....?).
[Galaxy Tab S2 Android Development] ashyx:
Not connecting in download mode is a separate issue, you need a windows OS for that. As long as you can get to download mode then you need to sort out the PC side.
[Galaxy Tab S2 Android Development] juniper1982:
thanks ashyx.

I have access to windows computers at work, but of course they were all down today.

However, you have to love the open source community. I used heimdall (open source replacement for odin) and it worked a charm. Flashed your TWRP and it's up and running again.

I thought I'd have to buy a new device!

Anyway, your twrp is up and running. Do you not recommend flashing through the twrp app? That's what messed my device up in the first place.

---------- Post added at 01:29 PM ---------- Previous post was at 01:27 PM ----------

Also, does adb just not work for this device? The trouble is that I couldn't turn on USB debugging because it was soft bricked. So I don't know if adb was being blocked because of that.
[Galaxy Tab S2 Android Development] bitelmaniaco:
So, with the last update can I:

- 1 flash the last version on Sammobile uploaded by ODIN

- 2 flash the last version of twrp by ODIN

- 3 flash the last version of SuperSu?

That was awesome!!!!
[Galaxy Tab S2 Android Development] nostupidthing:
Oh come on you Flashed the T713 version onto T710?????

---------- Post added at 02:59 PM ---------- Previous post was at 02:58 PM ----------

Does nougat rom has new bootloader?
[Galaxy Tab S2 Android Development] ashyx:
Blimey, didn't notice that, but I'm sure it was the correct version as he used the TWRP app.
[Galaxy Tab S2 Android Development] juniper1982:
well, you'd think that.

Did I use the wrong image? OK. So, that was idiotic. But in my defence, what the hell is up with all these indecipherable codes. Oddly, the T810 (perhaps someone can tell me it's magic code while we are at it), wasn't listed in the TWRP app. There were only two listed under galaxy tab s2: gts210vewifi and an 8.0 inch tab.

I ordinarily flash these the traditional way (download image, flash from twrp) but I thought I would give the app a try. That's what I get for being lazy. Also, I think gts210vewifi is for the T813, not the T713. Correct me if I am wrong.

well, lesson learned, and thankfully cheaply this time.

While I am here, one thing that I don't get: what is the role of rooting in all this? Once I have a device with TWRP as a recovery, why do I need root? I think that's the situation I am in now as the TWRP i just flashed (from this page) is advertised as without SU.

I understand why you want root for doing things when the device is on, but do I need it to flash another recovery or another ROM?
[Galaxy Tab S2 Android Development] nostupidthing:
I Blame Samsung for all these confusion lol.

BTW would you recommend flashing Nougat to get the bootloader up to date?

---------- Post added at 07:42 PM ---------- Previous post was at 07:40 PM ----------

Chill man

VE = value edition = Samsung way to distinguish 2016 tab s2 with snapdragon processors
[Galaxy Tab S2 Android Development] ashyx:
The nougat rom will have a different bootloader, but it's highly likely to be a patched MM bootloader. If you look at the kernel version in settings I bet it's just the same as Marshmallow?
[Galaxy Tab S2 Android Development] ripee:
Speaking of which, a tar of the T810 nougat bootloader is in the BL_CP folder in my signature ;) It's running fine on my tablet with your twrp_3.1.0-1_sm-t810_13317.tar
[Galaxy Tab S2 Android Development] juniper1982:
I am chilled. That was mostly tongue in cheek. Sometimes, these things are easy to overlook.

Anyway, for others, from what I can tell, TWRP does not support this device from their app.

Also, my question on rooting is serious. Does one need to root if only interested in installing recoveries and ROMs?
[Galaxy Tab S2 Android Development] ekitiboy:
Ashyx

Thanks for your awesome work

Just two questions

1. I have just installed Nougat on T815. Will this work on it.

2. Is rooting available for T815 on Nougat? If so, can you provide a link?

Many thanks
[Galaxy Tab S2 Android Development] ashyx:
From the OP:

So yes.
[Galaxy Tab S2 Android Development] ekitiboy:
Thanks for your reply

What about rooting?
[Galaxy Tab S2 Android Development] ripee:
Assuming your build doesn't have built-in root, flash SuperSU, it'll flash itself as system-less root by default.

You are so fast btw .

But still after flashing the TWRP give me the same screen.
[Galaxy Tab S2 Android Development] ashyx:
That's not blank, that's dm-verity kicking in because you have made modifications. You need to flash Supersu or the no-verity-no-encrypt_ashyx patch in TWRP.

You don't need to reset just force reboot to TWRP immediately after flashing TWRP. You MUST NOT allow to boot to system.
[Galaxy Tab S2 Android Development] NeWONEx:
But mine is encrypted , how could i patch it with no-verity-no-encrypt_ashyx ?

I planned to flash magsik , can it fix this issue ?
[Galaxy Tab S2 Android Development] ashyx:
Did you enable encryption or is it by default?

Either way you need to use the FORMAT DATA button in TWRP to remove encryption then flash no-verity-no-encrypt_ashyx.
[Galaxy Tab S2 Android Development] NeWONEx:
No i enabled it by myself [emoji53] , so there's no way to have root and encryption at the same time , because i did that before in MM. Don't know why it's not working here.
[Galaxy Tab S2 Android Development] ashyx:
Theoretically yes. But you still need to disable dm-verity.
[Galaxy Tab S2 Android Development] NeWONEx:
So if i stopped dm-verity , I still can have both root and encryption?

I'll try supersu or magsik after flashing TWRP immediately, maybe it can help in my case.
[Galaxy Tab S2 Android Development] ashyx:
Supersu automatically disables dm-verity. Not sure if Magisk does automatically, I expect it does if the zip is installed first. It is an option through the Magisk manger app if you install it first.
[Galaxy Tab S2 Android Development] NeWONEx:
I tried both of them but still not working and the same screen . I think the only way is by decrypt the device.
