I think I totally bricked it now. I had everything working and root access but FRP lock was turned back on after I added my google account so when I rebooted I got the message.

"Security Error: This device has been flashed with unauthorized software & is locked. "

---------- Post added at 09:53 AM ---------- Previous post was at 09:26 AM ----------

Okay I recovered by using Smart Switch Device Installation. Think I'll give up on the TWRP for a while lol
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
You need to enable OEM unlock in developer settings.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] murphinator:
Yes, unfortunately the T825C firmware doesn't have that option.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Of course. CROM service apk is supposed to do that.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Oh_wow:
I flashed AQDC and used the file starting with AP in odin with no issues. I did bootloop when I skipped the no verity file...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] johnp357:
I did this but whereas I was originally successful with the stock firmware the UK version will not allow me back up and mount the data. So no back up or even an option to load the hide or supersu.... sigh. Missing something.. anyone?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
That has nothing to do with the firmware. Read the OP again.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] eos:
Hi. I would like to test the theory from post #342 that Magisk on stock kernel does not break WiFi and/or Bluetooth. Can someone please tell me where or how I can get the stock kernel as opposed to installing the whole AQDC firmware via Odin?

On a side note, I have managed to successfully install Magisk (all green) on my SM-T825 following the recipe from OP and simply patching Magisk instead of SuperSU. The WiFi and Bluetooth issues still persist though. :(
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] napx:
No any WIFI/Bluetooth issues with patched stock kernel + Magisk 12

a week after rooting, I turned off Developer Settings, and updated super su then "The SU binary needs to be updated. " appears, so i updated it and rebooted but it got stuck on boot and it appears "an error has occured" thing. what to do? do i need to reflash the firmware? thanks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] eos:
Thanks napx, sounds promising. So, where can I get that patched stock kernel??? Or do you mean one of the device-related links from OP above (e.g. https://www.androidfilehost.com/?fid=673368273298952403 )?

---------- Post added at 08:00 PM ---------- Previous post was at 07:57 PM ----------

Hi. I believe someone said something here about SuperSU 2.82 having too many issues and that we should therefore stick to version 2.79 for the time being. I suggest you use the link from OP, flash it over in TWRP (not the whole firmware) and refrain from updating it if this approach has helped you.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
The other issue is he disabled developer settings. Developer settings needs to remain enabled.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] WS24:

Thanks!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Karaokegod01:
Is there any way you can send me a link with the directions because as of right now I can not get mine to root.I am able to flash the twrp but when it goes to boot in recovery mode it just loops
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Update your device to the latest firmware.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Karaokegod01:
It will not allow me to update to the latest firmware because I have already flashed Twrp with odin

I have the USA version Wi-Fi only does it matter that it is the Baltic version and do I flash all the files in that folder once I unzip it and also do I need to reflash twrp after? I really appreciate you helping me out my friend
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Probably not, but why not flash the US version? If you do flash it, I'd suggest just flashing BL and AP.

TWRP Needs to be flashed afterwards.

I'm having a similar issue as the guy with /data mounting problem a bit back.

Running T820XXU1AQD6 (which seems to be the newest version?) which boots fine right now. When I install TWRP from the OP with Odin, it cannot boot /data. The beginning of the log says

Could not mount /data and unable to find crypto footer

and upon an attempt to wipe data I get a few lines of errors

Failed to mount '/data' (Invalid Argument)
...
Unable to mount storage

Going through with dm-verity ends with an error about mounting /data and it hangs it at boot.

My log is attached
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
No need to post the log, just follow the instructions in the OP correctly.

Hi,

Thanks [MENTION=4899305]ashyx[/MENTION] for all of your work on this and for assisting so many users.

Do you know your changes will make it into an official twrp release? I tend to be a bit paranoid wrt unofficial builds.

hi are there any kernals for the 820 that are stable or am i best with stock
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Shroomalistic:
i was able to successfully install twrp and supersu on my new galaxy tab s3!! thank you.

Now im trying to find the right info but theres alot to go threw on this thread. If I wanted to fully recover my device back to stock( remove TWRP and flash stock firmware back) what steps would I need to take. Im an extreme noob to android but im a quick learner.

When I download the firmware from the net, I cant find any for USA. What am I doing wrong?

I would like to get netflix working again, I was able to install it but it looks like it only plays in standard def.

Main reason I rooted and installed twrp was to install the adoptable storage patch, I didnt know it would break netflix.

Sorry if this has all been answered, i cant seem to find it.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
It's root that has broke Netflix not twrp nor the patch.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Shroomalistic:
So if I remove SuperSu, netflix will go back to normal? Is that whats keeping it from playing in HD?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] eos:
How do you know it is not playing in HD? Could it be that some titles (e.g. Deep Space 9) were never recorded in HD to begin with? I have yet to find an option in the mobile Netflix app that tells me things like current streaming speed etc. I can do that on my TV, not in the Android app though.

Another thing to try (without which Netflix would not even start on my SM-T825 with the latest Magisk instead of Super SU): boot into TWRP and use its File Manager to go to /system/vendor/lib. Rename liboemcrypto.so to liboemcrypto.bak and restart your device.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] diehard2013:
hello,

I conldiit find an answer is the first pages.

Does rooting (super su) disable or cripple stock apps/features such as Game Launcher, Secure Folder or Soundcamp?

I know about Netflix and Knox I don't care.

Merci.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Just tried on my t820, game launcher works with root, I don't seem to have soundcamp on my device. As for secure folder I don't use it but the menus in settings appear to function normally, hope that helps

---------- Post added 11th July 2017 at 12:08 AM ---------- Previous post was 10th July 2017 at 11:51 PM ----------

Further to that, just downloaded Soundcamp and it works fine
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] badJester:
Regarding Netflix:

My Netflix isn't playing at all after flashing twrp. It opens and shows a loading indicator, but nothing happens then. I could not find any message in logcat that indicates, what's wrong. As far as I could see from other users, root only removes Netflix from playstore but after installing it (e.g. from their website) it worked without problems.

Regarding Secure Storage:

After flashing twrp, my logact constantly shows the following error:

E/SecureStorage: [ERROR]:SPID(0x00000000)The kernel binary has been changed.
E/SecureStorage: [ERROR]:SPID(0x00000000)The platform/kernel binaries should be synchronized for running Secure Storage.
E/SecureStorage: [ERROR]:SPID(0x00000000)Please use the same version of platform/kernel binaries.

I don't know if this is affecting the secure folder, because I don't use it. So this is just a note.

Regarding Wifi:

[MENTION=4899305]ashyx[/MENTION]: I also flashed the permissive kernel but returned to this here. I now also have the problem, that the wifi connection gets lost after restarting. I used the App "WiFi Key Recovery" to show the wifi password after I entered and compared it to the one that is shown after restarting. The passwords are very different. I don't know if this is helpful for you.

Thanks for your work, by the way!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
The warnings you posted from logcat I'm aware of and precisely the issue which is why secure storage needs to be disabled, but the flag has no effect on this device and also likely the reason for the different passwords. One will be in encrypted form.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] fkofilee:
Hi Ashyx

I have a few questions about TWRP and your Permissive kernel.

I am unable to edit the system partition in any form as it is still protected with KNOX and will either reboot or lockup when attempting to remove a file etc

I am rooted on V2.82 and have the latest firmware AQF3 / AQE6 - I havent flashed the Permissive Kernel yet. (Im about to however)

Do i need to boot into TWRP and wipe data If i have already flashed TWRP / No DM Verity / SUperSU ?

Also does your permissive kernel allow for System RW and removes Knox in full on the current Software?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
How are you attempting to modify the system partition?

Dm-verity should already be disabled by SuperSU.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] fkofilee:
Remove Some Apps / Deleted Media Ringtones and also Apply Adaway.

Adaway doesn't currently apply because it freezes everytime i try to apply it.

It does boot and DM Verity as mentioned should be disabled with Super SU which is fine.

But ive flashed botht the Super SU 2.82 and the Fix you provide after that as per the instructions .
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Not what, how? As in what are you using to delete the apps?

Tbh I don't really understand why people remove stuff from the system partition as there is no benefit.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] fkofilee:
Completely agree haha, however i debloat mine with Tib Backup etc...

However apps being used include - Root explorer - Shell Explorer - Tib Backup and ES File Explorer

But even that won't remove apps after full root... .

It is a strange one, but everytime i attempt to get Adaway to install accordingly - The system freezes and i have to force reboot

Also as well making any amendments to the system partition does the same thing.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
I would try SuperSU V2.79 sr3. I've seen the issue reported before in the SuperSU thread.

Also are you using systemless Adaway?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] fkofilee:
I did notice that there were some issues with 2.82 -

Yes - The latest version of Adaway does use systemless root to write to the system.

---------- Post added at 13:53 ---------- Previous post was at 13:27 ----------

Ive installed SU 2.79 R3 It disabled knox which is a good thing. Lets see if it makes a difference

---------- Post added at 14:04 ---------- Previous post was at 13:53 ----------

Adaway etc and deleting files still fails. Its not giving me root access even though it says root is there. This is really weird...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Adaway shouldn't write to system in systemless mode. Did you check systemless mode in Adaway?

Can you get a root shell in adb or a terminal emulator?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] fkofilee:
Yep... SU even comes up for Term Emulator

I have just factory reset my tablet again and followed your instructions all the way through for installing root on the device

Still dies... So i cant mount the system partition on this one :/

Tried Magisk and SuperSU and while it appears to give root access no root apps allow modification the system partitions also aswell Adaway still wont work and deploy the hosts Systemless Root etc

---------- Post added at 15:48 ---------- Previous post was at 15:19 ----------

Would it be worth me rolling back to AQDC?

You permissive kernel works on that? :) Could the cause be that im not able to get a permissive kernel etc ?

Flashing the Permissive kernel on the current FW doesnt work - It doesnt boot... (Not AQDC)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] fkofilee:
Sorted! Rolled back and now i can write to system partition with no issues. :) AQDC works great.

Plus superSu 2.82 flashed along with No Encrypt zip and its flying...

Thanks very much :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] atomiX_X:
I'll be getting my T820 sometime this week so I just finished reading this whole thread to prepare.

It would be great if I could get some clarification on something regarding the encryption of the DATA partition.

Personally, I prefer to have it encrypted but I take it the main reason to have it disabled with this device at the moment is to be able to mount it with TWRP to do backups/restores. Is there a reason DATA currently can't be decrypted by TWRP on this device even if the passcode is provided? Perhaps it's just because it's still too early and this functionality will be added in a later release? This was the case for the Nougat release on my Nexus 6P and TWRP was updated to fix this afterwards. Maybe not exactly the same core issue but it was something that had to be implemented into TWRP.

Is there another reason, maybe?

In any case, I can handle formatting DATA and having it decrypted if that's the only way to go.

Also, thanks for all the hard work you've put into TWRP and your kernels, ashyx!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ianmacd:
I just wanted to say thanks to [MENTION=4899305]ashyx[/MENTION] for this latest port of TWRP.

After two years with a rooted T710 (also done according to his instructions), first on Lollipop, then on Marshmallow and most recently on Nougat, I'm passing the device on to my wife and have upgraded to a shiny new T820.

Thanks to this thread and TWRP, after upgrading my new device to the latest firmware, I was once again able to decrypt /data and root the device in mere minutes. After that, it was a simple matter to restore almost everything from Google and Samsung's cloud back-ups. The rest I can pull over from Titanium.

So thanks to [MENTION=4899305]ashyx[/MENTION] for continuing to support Samsung's tablets and allowing us to utilise their pull potential.

Recently bought the SM-820 and hope to TWRP and gain root access.

Have used your files and followed directions exactly 3 times.

After TWRP flash immediately try to boot into recovery - never see either

TWRP or stock recovery. Only two lines of recovery and loop into it.

Fortunately downloaded QD6 build of stock firmware before beginning and Odin it back on each time.

Any suggestions would certainly be appreciated.

Hi, after flashing supersu 2.76 and then no-verity-no-encrypt_ashyx, i reboot and now it never goes past set warranty bit : kernel

I also tried flashing magisk over supersu but im still stuck at that screen. Im still able to boot into twrp.

What choice do i have? Im thinking to wipe dalvik, system, data, internal storage, cache, misc and start fresh by flashing the stock rom. But then where do i get a stock rom if the sites in the opening doesnt have the USA version?

Thanks to anyone that can help, my tablet cannot go past the boot screen with set warranty bit : kernel

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jchen12:
This is what i did after it booted to twrp,

swipe to allow modification

wipe>format data, typed yes to confirm

back to main menu checked that mount had data, cache , micro sd checked

then flashed supersu 2.76, then flashed no-verity-no-encrypt_ashyx

reboot and then stuck at screen that has set warranty bit : kernal

im going to download the 2 files again and try and report back

also if i do a complete wipe including internal storage and system, misc and use TWRP to flash a firmware from updato, i can return my tablet to stock and try again all over again?

3) will factory reset remove twrp?

Turned off, power+down volume+home = ok, download mode. Load .tar twrp provided here, selected it in AP, when I click start it shows FAIL..

Any help?

EDIT: OEM UNLOCK enabled.

Some more info:

TWRP flashing through Odin resulted in boot loop with blue name "Recovering Boot" and some more texts...

Then I tried to Flash Rom Stock back = soft brick (Odin Failed)

A little desperation!

Discovered that Odin 3.12 solves this. Could flash stock ROM.

Tried now with Odin 3.12 flash TWRP... no deal

Back to stock and now not doing anything...

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sameekou:
I followed instructions on first page as far as I could, however...

1. It mentions ADB Backup; is that necessary for the root to work? Or is it only to backup data?

If so and I can't do it in the first attempt, how do I proceed? Flash it again? Because after that it will enter in Boot Loop.
