Just noticed a minor issue with the T710 5.0.2 version. In the Reboot options pressing "Power Off" reboots back into recovery instead of turning off.

Would you mind sharing your device tree?

edit: only reason I ask is it's been a loooong time since I've compiled a recovery for an unsupported device and I'd like to get back in the loop... only my attempts at doing so are failing lol. Thanks.
[Galaxy Tab S2 Android Development] ashyx:
I don't have a fully working device tree yet.

The device tree I initially created to compile twrp always failed to boot even though the compile process always completed successfully.

I finally managed to build a bootable version by porting some of the binaries and libs from another device and using some of the files from the compile.

It seems when compiling from the latest 5.1 omni sources there is an issue, well for me anyway.

I contacted big biff on IRC about this and he seems to think it should compile OK and doesn't know what the issue is.

However I can't even get a bootable version from existing working trees.

I can't be bothered reverting everything to earlier sources so just used some of the working files from the build I compiled from source and the rest ported over.

I still haven't managed to nail the issue.

If you want I can get something up on github and maybe we can work on it to get it booting?

You will have to bear with me though as I deleted a load of stuff as I needed the space, so it may have gone.

What is the issue you are having?
[Galaxy Tab S2 Android Development] BigBot96:
I'm getting the same issue where it won't boot. Sits at the BL with the Recovery is SE Android warning. Can't get past that dagum screen. Here's my current tree: https://github.com/BigBot96/android_device_samsung_gts2wifi

Compiles without errors but no go. The last recovery I ported was for the Verizon Galaxy Tab 2 7.0 LTE and it was very simple to get up and running. Both CWM and TWRP.

I have now installed windows on my mac and will try to use the windows version of Odin or Heimdall with your files (kernel, twrp, ...)

Thank you for your help. I'll come back and let you know if I succeeded.

I tried flashing your kernel, cf_autoroot (I think it is yours), TWRP in windows and everything worked flawlessly the first time.

I have only one question. When the Tab S2 boots now, there is, in the upper left-hand corner in red, "kernel is not seandroid enforcing" or something like that. Is that normal or should I fix that somehow?

Thank you for your help.
[Galaxy Tab S2 Android Development] ashyx:
It's just a warning, it affects nothing.

Which kernel did you flash?
[Galaxy Tab S2 Android Development] Darran T:
I flashed t710_5.1.1_boot
[Galaxy Tab S2 Android Development] iStation:
I looking forawrd to it.

Please update t815 please. Huhu :(
[Galaxy Tab S2 Android Development] darkmen:
Hi, need a hint

S2 T815 cant run any custom recovery (tried all CFAT and TWRP), just stays on logo.

---------- Post added at 12:55 PM ---------- Previous post was at 12:52 PM ----------

This happen when the kernel image (boot or recovery) has no SEANDROIDENFORCE signature. Normally need just to append this signature to the end of image.
[Galaxy Tab S2 Android Development] ashyx:
You have to enable OEM unlock first in developer settings.
[Galaxy Tab S2 Android Development] darkmen:
Yes, in case OEM unlock is disabled ODIN cant flash custom binaries.

In my case it was wrong model (bootloader shows other model), so now it's solved.

Interesting, why dofferent android versions require different cfar (recoveries)?

Encryption Issues

Howdy,

(First XDA Post, please be nice and help me learn)

I flashed TWRP with no issues at all (thanks for making it btw), I have my tablet encrypted. I am able to boot into recovery with no issue, but it doesn't offer a means to unlock the encrypted storage (both internal and SD card). I had this same issue with my Galaxy S6 before I threw a custom rom. Anyway I can't root my tablet since TWRP can't really read or write. Is there a way around this?
[Galaxy Tab S2 Android Development] noratroll:
I don't know if there is a way to manage this, but I did not find any. Having been in the same situation as you are right know, I had to completely re-flash the Samsung Stock Rom. Afterwards I booted the device and was prompted to enter the encryption password. I entered it but it was not accepted. Now I fully wipe in TWRP and it worked.

It's a quite complicated situation since TWRP seems not to be able to decrypt the device partitions.

Furthermore, I do not guarantee if it will work on your side, too.

Best regards.
[Galaxy Tab S2 Android Development] ashyx:
Encryption wont prevent you from flashing supersu and gaining root.

TWRP doesn't support Samsung encryption yet.

If you want access to your storage you will need to format the data partition.
[Galaxy Tab S2 Android Development] noratroll:
When i encountered the same situation, it was not possible to access data partition from within twrp
[Galaxy Tab S2 Android Development] noratroll:
Sorry for having having bothered you. Does not happen again.
[Galaxy Tab S2 Android Development] Supersanborn:
Apologies if this has been covered...I see this on the original post:

Has anyone had any success flashing this on the T817T (5.1.1 version) and keeping LTE? I see no mention, so I'd like to be super sure before I end up paying for service on a tablet that cannot use it. Thank you!
[Galaxy Tab S2 Android Development] ashyx:
Recovery has nothing to do with the radio and is totally independent of the OS.

Whether the device is wifi or LTE is irrelevant.

Flash either the T810 3.0.2-1 or T815 3.0.0-1 version.
[Galaxy Tab S2 Android Development] Supersanborn:
Oh, I thought I read that flashing a kernel to achieve root would mess with LTE though.
[Galaxy Tab S2 Android Development] ashyx:
Your not replacing your kernel, recovery uses its own independent kernel.
[Galaxy Tab S2 Android Development] Supersanborn:
Ok, thanks again!
[Galaxy Tab S2 Android Development] hieronymos:
Ashyx, do you have an idea what would be needed to make ADB work?
[Galaxy Tab S2 Android Development] ashyx:
I've tried everything I can think of. Something in the kernel causes the issue.
[Galaxy Tab S2 Android Development] hieronymos:
I tried different precompiled kernels, but they all seem to do the same thing - and they were all based off of the Samsung sources. I tried building the Samsung sources myself, but they won't compile properly, there is a problem with the .o.d file of muic_task.c in the muic-universal module. Unfortunately, my competences in C are so unexistant that I had to give up there. I tried disabling that module altogether, but the resulting build had no adb at all afterwards (after all, muic is Samsung's "micro USB switch device driver" - but the fault may very well lie in the handling of the USB switch by the driver).

Did you have the same problems with the Samsung drivers? I checked out your kernel sources on Github as well, but they had the same problem.

The error where I have to give up looks like this:

twrp/kernel/samsung/gts210wifi/include/linux/compiler-gcc4.h:36:45: fatal error: opening dependency file drivers/muic/universal/.muic_task.o.d: No such file or directory
[Galaxy Tab S2 Android Development] ashyx:
Nope, kernel sources compiled fine.

Which tool chain are you using.

Is your system 64bit?

Do you have the correct defconfig?
[Galaxy Tab S2 Android Development] hieronymos:
I'm working with the Omnirom sources - the toolchain came with it. The system is 64bit and I use the gts210wifi_02_defconfig on the new kernel, exynos5433-gts210wifi_defconfig for the older ones... I'll try setting up another fresh VM to see if it's my system. Otherwise, it would probably be quicker if I just write a bash daemon in the recovery that can pick up shell scripts.
[Galaxy Tab S2 Android Development] ashyx:
You're just building the kernel right?

You don't need any other sources just for the kernel. I build with Linaro 4.9.

http://releases.linaro.org/14.09/components/android/toolchain/4.9/
[Galaxy Tab S2 Android Development] hieronymos:
Hi, after I found out that the kernel actually needs version 4.8, it compiles - but ADB still doesn't work. In the end, I found it much easier to add a script to init.rc that sources another script that I can place somewhere on the sdcard. This way I can execute commands in recovery without rooting the ROM, but I need to reboot if I need to add other commands. Thanks anyway!
[Galaxy Tab S2 Android Development] RMXO:

[Galaxy Tab S2 Android Development] jcadduono:
There's actually a ton of things wrong when you try to use build output folders with the Exynos kernels!

(at least the error you mentioned is due to trying to include subdirectory source codes into a parent level Makefile, I simply made the universal folder its own Makefile to fix this)

You may have better luck with this:

https://github.com/jcadduono/android_kernel_samsung_exynos5433/tree/twrp-6.0

You will need to use:

DEFCONFIG=samsung_defconfig/twrp_defconfig
DEVICE_DEFCONFIG=device_gts210lte/device_gts210wifi/device_gts28lte/device_gts28wifi
VARIANT_DEFCONFIG=variant_<device>_eur

(I like to use variant and device additions so I only need to edit 1 base config to work for all devices/variants)

select version of twrp for T715 w. Marshmallow

Hi ashyx,

you kindly answered me some time ago about compatibility on T715 for Lollipop:

" T710 version will work on T715 " (YES, worked fine on T715 w. Lollipop, thanks a lot !!!)

Actually you divide versions:

TWRP 3.0.2-1 for Galaxy Tab S2 T710/810 models - Lollipop 5.0.2/5.1.1/6.0.1

[*]TWRP 3.0.0-1 for Galaxy Tab S2 T710/715/810/815 models - Lollipop 5.0.2/ 5.1.1/6.0.1

Can I (successfully) install the

TWRP_3.0.2-1_sm-t710

after installing Android 6.0.1 German Stock version to my T715?

tx for answer

(& sorry if I did not find already given answers ;) )
[Galaxy Tab S2 Android Development] Fenyx13:
Which twrp version would work for sm - t817w on marshmallow?
[Galaxy Tab S2 Android Development] ashyx:
Yes you should be fine with the T710 version, the only issue would be when installing a custom rom which asserts it's for a a T715 which is relatively easy to address.

As long as it has the same chipset then T810 or T815 should work.

Samsung encryption doesn't SUPPORT BY TWRP

(Don't ask this question again like what I did)

Thanks btw

All what you can do flash TWRP and connect your device to the PC copy SuperSU file inside "sdcard" file and install , than remove it because you can't use it again. Or simply use USB otg

Ashyx, I downloaded TWRP 3.0.2-1 for T-810 already in April but it reported itself as TWRP 3.0.2-0. Just to make sure I downloaded from your link again and it is the same version as in April.

Is this just a cosmetic issue or is it possible the link is outdated?

[Galaxy Tab S2 Android Development] almahix:
Ashyx, I am really enjoying my T813 thanks to you and your generosity. I am wondering though if there is a work around in twrp to mount or backup the data partition? :confused:
[Galaxy Tab S2 Android Development] ashyx:
Did you encrypt your device? Data should already be mountable.
[Galaxy Tab S2 Android Development] NeWONEx:
There is something wrong when I flash Gapps Aroma. It seems touch work in portrait but TWRP is landscape. If I swipe from left to right it scrolls up and down.
[Galaxy Tab S2 Android Development] almahix:
I did the format data in twrp according to the instructions. I don't know how it would have been encrypted. Nevertheless, I repeated the format and install your zip and it seems to be alright now.

Edit...I installed my apps from Google, copied a few folders from my home PC via mtp, and reconfigured my tablet. When I went into recovery again to do a backup, my data partition is unmountable again. TWRP says something about not finding encryption footer or something. What's happening?
[Galaxy Tab S2 Android Development] ashyx:
You've re-encrypted the data partition.
[Galaxy Tab S2 Android Development] almahix:
I restarted from scratch. Formatted data partition in TWRP, did basic setup, and restored apps from Google. Booted back into TWRP to backup what I had done far, and already /data is inaccessible. What am I doing wrong? How could the partition get encrypted?

I did some further investigating. Format data, flashed your no encrypt and su , then did minimal setup, skipped everything but wifi, and terms and conditions ack. Data was already encrypted. I am baffled.
[Galaxy Tab S2 Android Development] noratroll:
Some time ago I struggled with a similar problem. Eventually, i could solve it after having reflashed Samsung stock Lollipop (which I indeed preferred over Samsung stock Marshmallow before I changed to Resurrection Remix Rom)

After having flashed the Samsung Lollipop via Odin, I rebooted and the device was asked for the device PIN, but it did not work. But since then the encryption was gone.
[Galaxy Tab S2 Android Development] ashyx:
As far as I know the T810 doesn't encrypt by default.

Are you sure you are FORMATTING and not WIPING the data partition?

Also are you able to access the data partition right after FORMATTING?

Post the twrp recovery log.
[Galaxy Tab S2 Android Development] almahix:
I think I figured it out. It is caused by flashing the su. I did the format data and flashed your no encrypt zip, then rebooted and did the minimal setup. Device still unencrypted. Went back to TWRP and flashed su. Rebooted, device is encrypted. I am going to do everything but su and see how we stand. Will advise. Thanks again for all you do superdev.

Edit...I have fully configured the tablet and made a first full backup. Everything except su. I am still not encrypted.

Now that I have a full backup that I can restore I am willing to help you test any fixes to your su.
[Galaxy Tab S2 Android Development] ashyx:
This is probably due to the way supersu patches the boot image.

Flash supersu then immediately flash the no-encrypt zip.

This should prevent re-encryption.
[Galaxy Tab S2 Android Development] almahix:
I'll give it a go and let you know.

Edit..I formatted data, flashed su and your no encrypt, and I have su and I'm not encrypted. I tried to restore data from my recent nandroiud but that hosed things so I am starting from scratch and recnfiguring but it seems to be in order so far. Thanks for the advice.

Another edit... I have fully installed and configured everything. I have root and I am not encrypted. What I am is happy and thankful for all of your suggestions and instructions. It took a while but we have arrived.

Hi. I was trying to install Resurrection Remix 6.0.1 on my T815Y using the seandroidfix version of this TWRP linked earlier in the thread. It returned error 7, saying that the firmware is supposed for the LTE version and not the WiFi version of the tablet. Wierd, since T815Y is an Asia manufactured LTE version.

I realized that maybe this occurred due to the seandroidfix version of TWRP is saying that the device is the WiFi-version? I have no way to confirm this though.

I updated to the latest version in the original post of this thread (3.0.0-1 as of today) and everything works.

Now for my question - when I boot into TWRP, it's still showing up as 3.0.0-0. Does this occur to your devices too?

Hi there,

I reinitialized my t710 with SmartSwitch and flashed TWRP 3.0.2-1 via ODIN v3.10.7, booted into TWRP set as read only/systemless as per prompt... booted into the tablet, went through the set up... checked my device with ultimate "ultimate Root Checker" (it's new, supposed to be really good.) which said "rw System Folders" > "/data", I checked the device status > "Device Status : Custom".

Is there any way to avoid making "/data" read/write? Or is this tool mistaken, this could explain the trouble I've had with newest version of netflix and other apps after only just installing TWRP... :crying:

Thanks for your time and hard work on this app, any assistance you could provide would be appreciated.:fingers-crossed: :eek::good:
[Galaxy Tab S2 Android Development] ashyx:
Are you failing safetynet?
[Galaxy Tab S2 Android Development] wirelesskebab:
I initialized again and forced an update to gplay, tested with and w/o TWRP and it passed the localized safetynet test. Ultimate Root Checker seems to be picking up incorrectly on the /data folder, at least for my stock sammy rom.

I still don't understand the mechanism behind windvine flunking out, I'm pretty sure it has been doing it since before safetynet was a thing, it probably has some of its own checks. Disappointing, but I don't think you can do much about it since it seems to look for unlocked boot loader, system does too. "Custom".

Edit: Actually, not just an unlocked boot loader, but one other than its own, something to do with dm-verity maybe? I don't know.
