[Galaxy Tab S2 Android Development] jhill110:
Thanks [MENTION=4899305]ashyx[/MENTION] for the tip on the build. prop edit. Took me a bit to figure out I had to factory reset afterward to get it to work but now it does.

Ran across this site that has firmware (TAR) downloads. Seems they have them before samobile and others... Pretty fast dl speeds and is free. Thought it might be helpful for some.

The SM-T713 PG1/PG2 Is up and a lot more in the samsung section.

plz, fix recovery for 813/819, like for 713/719.

It has a bug with "adb shell"

CANNOT LINK EXECUTABLE DEPENDENCIES: library "libc.so" not found

thx
[Galaxy Tab S2 Android Development] EddYTG:
Sorry for asking. I have searched this thread but not have answer.

My Tab S2 VE has model number SM-T719Y ..... Can I use the process in this thread by using T719 to flash recovery and root my Tab S2.

Thank you.
[Galaxy Tab S2 Android Development] zardoz77:
I got a SM-T819n with LTE and german firmware + qualcomm CPU.

Does this work with mine? And you can get root by flashing super-su??!
[Galaxy Tab S2 Android Development] Jaycob2016:
Hi,

Has anyone getting " Set Warranty Bit = Kernel " at the boot up? or is that normal now after rooting ? If not how do I get rid of it ? Thanks.

Galaxy Tab S2 T713

Build # APGI
[Galaxy Tab S2 Android Development] jhill110:
Normal
[Galaxy Tab S2 Android Development] Jaycob2016:
Thanks.
[Galaxy Tab S2 Android Development] almahix:
I'm kind of surprised that ashyx hasn't changed the OP to instruct users to flash supersu before his no encryption zip. Doing these in the order he describes caused my SM-T813 to remain encryptedo. Reversing these two steps corrected the problem.
[Galaxy Tab S2 Android Development] ashyx:
Updated.

Supersu patches the boot.img and removes the modifications that the no_encrypt zip makes.
[Galaxy Tab S2 Android Development] Logidelic:
I've got the SM-T813 and followed these steps, finally flashing with T813XXU1APF4_no_encryptable_boot.tar. Unfortunately, after flashing it seems that wifi is no longer working (it won't let me flip it to on). What might this mean? It was working just fine before the flash. How would I go back to the stock firmware?

Thanks!
[Galaxy Tab S2 Android Development] ayamgoreng:
I think you followed the old guide

To return to original state, just flash your original boot image,

then patch it using no-verity-no-encrypt_ashyx in the page 1.
[Galaxy Tab S2 Android Development] LouK:
Or you could try this fix that Light1ng made for the T813 and see if it helps.

And, just for the sake of argument of course, if I was an imbecile and hadn't backed up the original boot image? :eek: (Answering my own question: downloading the stock image currently...)

Thanks for that. Unfortunately doesn't seem to do the trick.
[Galaxy Tab S2 Android Development] mms2020:
I installed the TWRP 3.0.2-1 bu following the guide. I had enabled the OEM unlock. Everything went well. I made nandroid back up as well.

Today I had a notification that super su needs to be updated. After update it rebooted the tablet but it is now stuck at "Custom Binary blocked by FRP. Secure fail: Kernel"

It does not let me boot into TWRCP or Samsung recovery. Any ideas how to fix this issue?

Thanks
[Galaxy Tab S2 Android Development] jhill110:
You may need to re flash the boot patch... Dunno...
[Galaxy Tab S2 Android Development] lourdes71:
TWRP is not installing on my T813. I'm used to using odin and twrp and rooting my devices, and I don't understand what's wrong. I flash it and NOTHING. I still get the normal android recovery.

Has anyone had this issue?

thanks!
[Galaxy Tab S2 Android Development] ashyx:
You need to re-read the instructions properly. [emoji19]
[Galaxy Tab S2 Android Development] lourdes71:
Hi ashyx

thanks for your quick reply

I did everything again BUT changed the USB cable and it worked (mysteries of wiring)

Now after flashing super-su and then dmverity the tablet won't boot - it says "something warranty - kernel"

the thing is, during flashing I got messages of "could not mount /data"...

can you help please? :rolleyes:
[Galaxy Tab S2 Android Development] ashyx:
You haven't formatted data.

You need to format data then proceed.
[Galaxy Tab S2 Android Development] lourdes71:
I did now, no "can't mount /data" this time... finished flashing, rebooted and the tab seems to be working and rooted (checked with root checker)

but I keep getting the message "set warranty bit: kernel"

How can I get rid of that?

Thanks
[Galaxy Tab S2 Android Development] ashyx:
You can't get rid of that message, it's part of the process.
[Galaxy Tab S2 Android Development] rgbigel:
Are there any success stories?

With all the problems tapped here (mostly because people don't read), I wonder if somebody is totally happy... or which limitations are unavoidable, like Knox and warranty. Apps not working? What about payment methods? Anything would help!

[Galaxy Tab S2 Android Development] ayamgoreng:
ota obviously not working, warranty depend on your country

a few samsung apps that detect knox don't work.

I didn't realise that we have payment methods. no such option/feature with our local T719/819.
[Galaxy Tab S2 Android Development] charis232:
Tell me friend what is the right order,you said you reversing the 2 steps but is not clear what you flashed first.I have Tab S2 T719 4G 8".I am from Europe/Greece

Thanks
[Galaxy Tab S2 Android Development] jhill110:
Format data, SuperSU then boot patch.
[Galaxy Tab S2 Android Development] nk33:
I just got this tab today - flashed twrp - now i cannot format data - it wont boot either - says verification failed.....what can i do??
[Galaxy Tab S2 Android Development] nk33:
**UPDATE**

I just downloaded the stock rom from Sammobile and flashed with ODIN, unfortunately i still get the message about verification failing...probably due to the bloody encryption again

When i try and reset to factory settings it just goes into a bootloop.

cant believe i got this tablet today and already f**cked it... can no one help?
[Galaxy Tab S2 Android Development] ashyx:
Just calm down and follow the instructions. Boot to twrp tap the format button then reboot to recovery. Install supersu then the no_encrypt_no_verity patch.

First boot may take a good ten minutes.
[Galaxy Tab S2 Android Development] nk33:
Hi mate, ok so this format button where is it? Twrp cannot mount any storage at all so i cannot copy any files to the tablet to flash even if I wanted to.

When i.try and wipe data it tells me it cant mount the storage.

Basically i.cant do anything
[Galaxy Tab S2 Android Development] ashyx:
It's right there under WIPE. Says FORMAT DATA.
[Galaxy Tab S2 Android Development] nk33:
Yeah, and like I said… .i.did that… and it doesnt do anything… lots of red writing saying it cannot mount the storage to wipe it.
[Galaxy Tab S2 Android Development] ashyx:
This has already been discussed and explained in this thread. Ignore the red writing.

Please pay attention. You are NOT wiping, you are formatting using the FORMAT DATA button.

Then reboot to recovery then install supersu then the no_verity_no_encrypt zip.
[Galaxy Tab S2 Android Development] nk33:
ok - thanks - i have now done this - i couldnt see the format button before... -

BUT...now i have done the format... how can i get those 2 files onto the tablet to flash them??? when i plug it into my pc the drivers fail to install (MTP USB device).

All my other tablets and phones plug in and the pc sees them fine.

Are there new drivers for this device?

---------- Post added at 10:24 AM ---------- Previous post was at 09:58 AM ----------

ok - i managed to get hold of an sd card from another device - i put the files on that and it all worked!

thanks for your help guys. i did panick and i usually dont.

i think because this encryption thing is new to me.
[Galaxy Tab S2 Android Development] charis232:
I have the T719,LTE and I am with the stock ROM.I read all the 52 pages so far,I wanted to ask.Following the first page for rooting is enough or I must install the boot image,because I read here that after the procedure...we loose the wifi.I installed the TWRP so far with guide of the first page and I want to continue to root.If someone can help with rights steps.

Thanks
[Galaxy Tab S2 Android Development] nk33:
i have T819 and i still have wifi
[Galaxy Tab S2 Android Development] charis232:
and you didn't install boot image?
[Galaxy Tab S2 Android Development] nk33:
i did flash the boot image patcher
[Galaxy Tab S2 Android Development] charis232:
Thanks nk33 for the reply.I meant the boot image we take from the stock ROM and not the boot image patcher

is the first page I suppose.Plz the name of this patcher so that to clarify the correct file.
[Galaxy Tab S2 Android Development] nk33:
mate i am sorry but now you are confusing me.
[Galaxy Tab S2 Android Development] charis232:
sorry for that,is my fault.This is from the first page: ""BOOT IMAGE PATCHER

Boot image patcher to remove DM-verity and Forced encryption.Flash the zip below with TWRP.""

This is what you mentined before?
[Galaxy Tab S2 Android Development] nk33:
yes - i followed the instructions on the 1st page, and my wifi is working 100%.
[Galaxy Tab S2 Android Development] charis232:
Thank you very much.I will do later the procedure and I hope to be succesfull
[Galaxy Tab S2 Android Development] nk33:
ok - but bear in mind that mine is the t819.....different variant to yours
[Galaxy Tab S2 Android Development] ashyx:
The instructions in OP are up to date. Just read carefully and you'll be fine.
[Galaxy Tab S2 Android Development] charis232:

I followed the procedure from the first page,everything went fine,no problem with WiFi.

Thanks all for the help.A last question,when Samsung release a new Rom for my TAB,this

means that I will loose the Root and I have to repeat the procedure?

Thanks.

Worked for sm-t713 t713xxu1apg1

Hello,

It worked for my sm-t713 t713xxu1apg1

I follow update steps as written on first post.

- Download 3 files (Supersu/twrp/image patcher) and store it on SD card

- change parameters ( Settings –> About device and then tap on Build Number seven times repeatedly + Developer option => USB debugging)

- Reboot device using POWER + HOME + VOL DOWN

- apply twrp via Odin (without reboot option)

- POWER + HOME + VOL DOWN + VOL UP

Once twrp is started

- Wipe => format /data

- backup all on SD card

- install image patcher

- install Supersu

- install image patcher (did twice as not sure about order)

- reboot

And then SuperSU was installed!!!!

Remarks about tutorial post :

- it could be nice to alert that you should download all 3 files (Supersu/twrp/image patcher). I had to remount sd during install

- I was not sure about image patcher order. It seems to be last step, but it's in 2nd in post.

Thanks
[Galaxy Tab S2 Android Development] ashyx:
It clearly states in the OP to flash the boot image patcher after supersu.
[Galaxy Tab S2 Android Development] abonne01:
Sure. but all is quite mixed... this part should be placed later, or maybe reminder of steps in order...

Anyway. Thanks a lot for hard work.
[Galaxy Tab S2 Android Development] Boroda095:
Good afternoon!

And whether there is a hope for release of the version of TWRP for installation without FORMAT DATA?

When updating an firmware, custom recovery it is replaced standard, and then it is necessary to do FORMAT again. When data small and it not a problem, but when there are a lot of data and settings - to update an firmware becomes not really good idea :)

Thanks for work!

Sorry, SM-T719 model :)
[Galaxy Tab S2 Android Development] ashyx:
No, just flash the boot image patcher before booting to system.
[Galaxy Tab S2 Android Development] Boroda095:
Good news!

I will try :)

Thanks!

Custom binary blocked by FRP

Hello,

after successfully root tablet, used it for some days... I restarted it. And now, bad luck, I have error message :

Custom binary blocked by FRP.
SECURE FAIL : KERNEL

I tried to perform the recovery booting, and use backup made with twrp on sd card..

It's trying to enter recover and just after i'm again on the same error message.. :(

I saw on forum that you need to uncheck the OEM verification in developer tab, but as it's not booting at all anymore, I'm stuck on this screen.

------ EDIT - SOLVED -----

I had to reset OS. I did it with samsung tool "Kies 3" (Tools -> init of firmware)

All was reset (OS, user, data) as if tab was new..

I had then to format and re-root tab.

It seems that OEM verification was reactivated when I added another google account on tablet.
[Galaxy Tab S2 Android Development] R E H:
i have the same problem, so i can reinstall the os from kies? because i was not able to enter recovery or falsh any thing from odin
[Galaxy Tab S2 Android Development] abonne01:
It worked for me...

[Galaxy Tab S2 Android Development] danizmax:
I was just wondering is there still an issue with TWRP decrypting data?

I read the following reddit post, and it seems TWRP should already support mounting partitions that are encrypted by entering pass code or pin.
[Galaxy Tab S2 Android Development] Gandicela:
[MENTION=4899305]ashyx[/MENTION]

In the Lightn1ng ROM thread you mentioned to split recovery images of 713 and 719. May I know if the current "twrp_3.0.2-1_sm-t713_23716.tar" still works as intended anyways? Thank you, please.
[Galaxy Tab S2 Android Development] brotbuexe:
If I only want to root, can I skip decrypting data and install supersu zip through twrp?

Was there any statement from [MENTION=631273]Chainfire[/MENTION] about no cfautoroot for this new variants?
[Galaxy Tab S2 Android Development] jabbermacy:
ok, just got my T713 and I have a noob question: my last Samsung experience in custom ROM required a restore from a factory image when I really screw up, so where can I find a full restore image for US version T713XXU1APG1? I can find other regions but no official source. Can you help me please? Also, is KIES for a restore a reliable option??
[Galaxy Tab S2 Android Development] ashyx:
Well firstly if you make a full device backup with TWRP (the whole point of a custom recovery really) you won't need the stock firmware.

Second the stock firmware is available in several places. Sammobile, updato, Samsung updates, kies.
[Galaxy Tab S2 Android Development] jabbermacy:
^ yeah, I get it, but I'd rather be safe. Sammobile doesn't have U.S.A version, neither does http://samsung-updates.com/, UPDATO finally DOES have it.

Of all devices, Samsungs are the ONLY ones to ever give me heartache, be it phone or tab...

(and thanks, BTW :))
[Galaxy Tab S2 Android Development] Gandicela:
I just simply installed TWRP on my 719Y, then flashed SuperSU. I tried to backup whole ROM into my ext SD card but failed. Was it because I never did the BOOT IMAGE PATCHER part?
[Galaxy Tab S2 Android Development] ashyx:
You can't backup data if it's encrypted.
[Galaxy Tab S2 Android Development] ashyx:
Actually they all have it.

Region XAR Cellular South.
[Galaxy Tab S2 Android Development] jabbermacy:
Question: if you read the OP it says nothing about flashing the un-encryption patch then backup. I assume you flash the recovery, then the patch, then backup? If no then how do you do a complete backup??
[Galaxy Tab S2 Android Development] ashyx:
You can't backup data if it can't be mounted.
[Galaxy Tab S2 Android Development] jabbermacy:
OK well I enabled OEM unlock already, flashed recovery and the patch, still cannot mount data so backup fails. Next?

Also got boot loop trying to get back into system, as if a backup helps if you can't boot it.

Last, tried to just wipe and install Lightning ROM and it cannot wipe, cannot mount file system.

PLEASE help me out, I did exactly as OP, can't do anything now...
[Galaxy Tab S2 Android Development] ashyx:
You didn't follow instructions exactly or you wouldn't be in this mess.

I suggest you reread the instructions regarding the installation of the boot image patcher.

It clearly states the solution to your problem.
[Galaxy Tab S2 Android Development] Gandicela:
I believe, as mentioned in the OP, these should be done as follows to remove the encryption.

Under the WIPE option in TWRP, press FORMAT DATA. Note this will erase all your data.

Press HOME in TWRP and go to INSTALL to flash the boot image patcher, file name "no-verity-no-encrypt_ashyx.zip".

Press HOME in TWRP and go to INSTALL to flash the SuperSU zip file.

Reboot SYSTEM.
[Galaxy Tab S2 Android Development] jabbermacy:
^^ bless you, brother! That's the correct process!! I think all is well, at least I can boot!! WOOT!!

2. Flash no-verity

3. Flash SuperSU

3. Flash no-verity

4. Reboot

SuperSU app is installed and able to update to binary 2.78 but fails root check. Any solutions?
[Galaxy Tab S2 Android Development] Xp3riaXpr3ss:
Download the original firmware for your device, flash with Odin and restart over.
[Galaxy Tab S2 Android Development] ashyx:
Don't rely on root checker apps. Many need to be updated to work with the latest versions.

If root apps are working you have root.

Try root validator.
[Galaxy Tab S2 Android Development] dxxvi:
I downloaded the firmware for my SM-T713 (T713XXU1APG1_T713XAR1APG2_HOME.tar.md5), the USB driver (and already installed it) and odin v3.12.3.

First, I run Odin3.exe as a regular user. I selected BL, AP, CP and CSC. And for each of them I chose the same T713XXU1APG1_T713XAR1APG2_HOME.tar.md5 file. Then I clicked Start. Messages in the Log panel said a lot of things were updated, for example, recovery, modem, system ... Then it failed after about 20 mins. Then I closed Odin and run it again as administrator. This time I chose only BL and it failed as in the screenshot. I removed the usb cable, Home + Volume Down + Power the tablet, then I saw "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". What should I do now?

Edit: I can Home + Volume Down + Power to put it in download mode now. Could anybody tell me the correct way to flash the stock firmware with odin? Thanks.

Edit 2: now I don't know how to turn it off :crying:
[Galaxy Tab S2 Android Development] HairyMilkshakes:
You need to load it under AP. Then, if you are stuck on the Samsung flashing loading logo screen, factory reset the device.
[Galaxy Tab S2 Android Development] Xp3riaXpr3ss:
Try this.

1. (Power + Volume Down) to turn off the device.

2. (Power + Volume Down + Home) to enter download mode.

3. Load Odin and make sure your device is connected.

4. Select "AP" to attach stock firmware (md5).

5. Press "Start" to flash after file checks complete.
[Galaxy Tab S2 Android Development] dxxvi:
It didn't turn off the tablet, just restarted it. I'm stuck at the SAMSUNG logo and I want to factory reset it, but Volume Up + Home + Power does nothing (maybe it only works when the device is off?).
[Galaxy Tab S2 Android Development] Xp3riaXpr3ss:
When you are restarting the device, interrupt the boot process by pressing the (Volume Down + Home + Power) buttons immediately when the screen blacks out.

DO NOT WAIT FOR THE SAMSUNG LOGO TO APPEAR.

Note: The combo (Volume Up + Home + Power) which you mentioned is used when you want to access custom recovery (eg. TWRP, CWM).
[Galaxy Tab S2 Android Development] ashyx:
I'm afraid you've made a real pigs ear of this.

There are literally countless guides how to use odin on the net. The firmware hosting sites even have guides.

Regardless of what state you are in hold POWER + HOME + VOL DOWN until you enter DOWNLOAD mode.

Load the MD5 into ODIN. Hit start when the check completes.

When the flash finishes your device will reboot and you should be good.
[Galaxy Tab S2 Android Development] dxxvi:
I guess I was freaked out that my tablet was bricked forever.

Finally, when my tablet run out of battery, I can Volume Up + Home + Power to go to the recovery and do a factory reset.

By the way, what does "real pigs ear" mean? Google seems not understand it.

I am trying to root my T719C (T719CZSU1APF1), however after flashing the TWRP in download mode and trying to reboot in Recovery mode failed.

It stayed on the "Samsung Tab S2" page (which left upper corner has some "recovery boot" wording) for around 1-2 minutes...then it reboot again into the normal mode.

Any ideas? Is my version too update for root?
