[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
Works as it should. Tried some apps that didn't work with enforcing kernel are now working. When I started the tablet the first time, kernel was set to enforcing, but you can switch it yourself to permissive with terminal or SELinuxToggler. The kernel then stays permissive after rebooting. If you need something special tried, don't bother to ask me.

You're from UK. I'm from Austria. Only 1 hour between us. Seems you're also "Live by Night". :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Zimus:
What apps were not working with SELinux set to "Enforcing"?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
I'm in the UK too. OK let's get cracking. You need that file but, how do I get it from my tablet I mean. I have not found anywhere to get it online, nowhere seems to have the AQDC one yet.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
Yesterday it was only available as OTA.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
So they don't make the full firmware available online for a while after OTA's?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
It's okay I'm downloading it now. I'm surprised you got UK version as I can only find Spain and Hungary.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
It seemed to just start downloading while I was back on stock. It was tiny but took a while to install. It's saying build number NRD90M.TM820XXU1AQDC
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
SELinuxToggler (when switching to permissive)

Lucky Patcher (when giving SU rights / and don't judge me now you can use LP for other things too. Not only for cracking apps.)

Haven't tried, but I think Apps2SD also have problems with enforcing enabled on Samsung devices. (I had problems with it on my Tab S)

And the TWRP app (not the official one) had problems with Online Nandroid Backup. (at least on Tab S)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Well we will soon see what the situation is. I take it TWRP still boots OK with this new firmware?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Let me just double check that.

---------- Post added at 06:59 PM ---------- Previous post was at 06:53 PM ----------

Ok.. TWRP loads but I can't get into the system, (first logo boot loop) also, data wasn't mounted by default so I used the format data option and it seemed to mount after that. I imagine this causes more issues for you... sorry
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
I really don't know. ATO firmware is for now only available as OTA.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
You need to remember each time you boot with the stock kernel your device will become re-encrypted and neither will your device boot with the custom kernel.

Now, what do you mean you can't get into system?

Boot image update: https://www.androidfilehost.com/?fid=673368273298952595

.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Sorry, I simply meant I couldn't boot. Shall I flash the TWRP again and run your patch?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
So twrp is now preventing your device from booting? This is because you still have dm-verity enabled. You need to patch the boot image or use the custom boot image.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Yeah, this slipped my mind. On it now. Give me a sec.

No issues - boots fine. Apologies for the oversight there m'lord.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
OK lol, so are we saying good to go on twrp and Kernel?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
As far as TWRP working, ROOT working and booting up just fine. We are good.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
OK then I shall recompile the kernel with a few extras and then post it in a separate thread incase anyone wants a permissive kernel.

Thanks again for testing.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
You are welcome, it's you who deserves the thanks anyhow. Would you mind PM'ing what those extras are for the sake of learning on my part?

Thanks again.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
By extras I mean just enable a few things in the kernel build such as NTFS, f2fs support, enable all available governors etc.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Ok, is it worth waiting around to try it today? or will it take a while?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
It's compiling as we speak. Will be ready within the hour.

Features I've included:

Permissive

Root restrictions removed

Knox disabled

NTFS support

F2fs support

Power efficient work queues

All governors enabled, Interactive set as default.

Any one of these could cause the kernel not to boot.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Righto. Will test it when it's done. ;)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
Do you compile TWRP and AQDC permissive kernel for the SM-T825 too? I would love to test too!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
No the kernel is still built from AQD6 source.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
How is it going Ashyx?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Damn compile kept failing at buildng F2FS driver, had to just disable it in the end to get it to compile.

https://www.androidfilehost.com/?fid=817550096634767347

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Do I flash it in AP in Odin? and with auto reboot on or off?

Bootloop, first screen
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Yes odin.

OK will try again tomorrow, might have fudged something up.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
do you have the thing to flash to get it to boot again, the original
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
The what thing?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Something I can flash to get it to boot up again.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Just flash the other permissive kernel I uploaded.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Cheers. I must be drunk
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Riokou:
Am I the only one having issues with d6 BL, and kernel; WiFi authorization fails on boot and when I tried the build.prop fix that works on the s7 it didn't fix it, also Bluetooth won't turn on no matter what I do. Sm-t820
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Ok, recompiled.

https://www.androidfilehost.com/?fid=457095661767159000

.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Not working either. This time, it reboots once after the first boot screen, then stays at the first boot screen doing nothing.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
No you're not the only one. I've missed that to try out. WiFi authorization fails and build.prop fix don't work, as you said. (SM-T825)

Edit: After switching WiFi off it won't turn on again until I reboot.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Riokou:
Do you have the same problem with the Bluetooth, and did you see if it worked OK before the kernel (I didn't) I'm just trying to figure out if its the official firmware or a derp in the kernel

Edit: forgot I can't check till I get home from work which will be almost 8 hours
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
I get issues with Wi-Fi when installing Magisk modules or at least I thought it was that.. fails to auto reconnect, have to re enter password etc
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
WiFi worked with stock kernel.

Bluetooth don't work correctly. I can pair but when I try sending a file it doesn't work. Then I tried to use internet over Bluetooth but also didn't work. I think it worked with the stock kernel, but I can't say it for sure.

---------- Post added at 01:23 PM ---------- Previous post was at 01:13 PM ----------

I don't have Magisk and WiFi also don't work. I tried Magisk a couple of days ago with AQC1 firmware and stock kernel and WiFi authorization worked after reboot.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Hopefully this one boots. I've also tried to address the wifi password issue. Password should stick after entering once.

https://www.androidfilehost.com/?fid=529152257862724724

.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Is wifi just not tuning on or not remembering passwords?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Riokou:
It fails authorization till you reenter the password, the Bluetooth tries to turn on but never actually does even with reboots
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HUBSi01:
When you start the tablet WiFi works but not remembering AP and password. Then I turn WiFi off and I can't turn it on again until I reboot.

(I looked at the wpa_sufficient file in data/misc/wifi folder and AP is still there, but when I reboot, it's deleted there too.)

Edit: I mean wpa_supplicant.conf.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
it boots but it's still saying enforcing and not permissive and the wifi is not saving, with mine, I'm sure it was magisk modules causing the problems, not anything you did.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Strange it SHOULD be permissive. Can you set permissive mode in adb with:

adb shell

su

setenforce 0

Also do you have Magisk installed which is faking enforcing mode?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
This worked, it says permissive, but the changes you made to WiFi made it always forget the password now, it was magisk modules which was causing my issue not what you did.

---------- Post added at 05:05 PM ---------- Previous post was at 05:05 PM ----------

dammit, it was probably that. I didn't realise that's how magisk works, sorry for that
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
OK I'll revert the changes, but honestly it should be the other way around. Strange!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Just so you fully understand what happens, it loads up WiFI, but instead of saying the WiFi network, it simply says 'WiFi' and I have to find my network and reconnect.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Was that every time or just the once?

Reverted: https://www.androidfilehost.com/?fid=817550096634767515
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Every time and it still is, and it only goes permissive if I do the adb command

Resetting always reverts it back to enforcing
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gpsrookie:
Hi

I had this problems with stock rom already bevor I had flashed twrp recovery or rooted the device. Therefore I think it has nothing to do with ashyx work.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Something must be setting it enforcing on boot. You can use selinux changer to set it permissive on boot.

https://xdaforums.com/showthread.php?t=2524485

Could you do me a favour and see if the original permissive boot exhibits the same behaviour?

https://www.androidfilehost.com/?fid=673368273298952595
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Yeah sure, but let me just get this right. Can I simply flash this on top of what I already have? or do I need to format and ensure everything is fresh?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
OK, flash with odin with auto-reboot unchecked.

As soon as the flash finishes immediately force reboot to twrp and apply the boot patch.

Then reboot as normal.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Blast.. I wasn't doing that way before. Would this explain everything?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Its only to disable encryption and dmverity. I've already disabled it in the recent versions.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Identical problem. So what's the next step?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
So, this is the original AQD6 kernel you flashed, but you didn't report problems with it previously or was that because you was still on AQD6 firmware?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
I believe I was on the AQD6 still at that point because then the other poster mentioned the new OTA, so I flashed stock to check for it myself.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Then maybe the wifi issue is related to that. There's a fix I could try.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Ok just let me know.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Well I won't post tonight nearly bed time for us lol.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Well I'm going to TRY and stay up and watch the boxing on BTSport.. but I normally fail to stay awake as I get older, lol.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
It comes to us all :crying:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
That's true. Well, have a good night and thanks for the attempts at getting this work today. Just one question; do you intend to buy this tablet in the future?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Well no, I think I've got enough with 5 lol. Enjoy the boxing. ;)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Ok, see how you go with this. Just flash with ODIN and reboot normally.

If you get any odd issues, you can revert by flashing NON-HLOS_AQDC.tar

It's still with the wifi problem, although it makes the tablet boot up much faster somehow.. Just so you know, even with the backup file you provided, the WiFi problem still persists! So it's like messing with it at all messes up the wifi somehow
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
It's strange that the ro.securestorage.support=false flag doesn't fix it.

Samsung must have changed something.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
I noticed that the WiFi is initially off for about 4/5 seconds before it turns itself on also.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
I found a neat little app that overcomes the wifi issue. Its called 'NeverForget wifi' . Tested it on 3 devices and it works.

Simly enter your wifi details once and it will connect the wifi every time.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
The latest firmware is AQDC, so you need this one: https://www.androidfilehost.com/?fid=817550096634767515

If your still having problems with wifi password then it should solve it whichever you are using.

You can flash this with ODIN or extract the boot.img and flash with TWRP.

Tab s3 master thread please

This is awesome news. But guys (admin), we need a dedicated master thread for the Tab S3 and have this moved over there. To mix the S2 and the new S3 in the same thread is a total mess. These two tabs are more than 2 years apart and are totally different hardware. Thanks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] hurray:
Very good news! Thank you both [MENTION=4899305]ashyx[/MENTION] and [MENTION=2313936]suzook[/MENTION] for your work!!! :)

Am I right with the assumption that all Tab S3 are delivered currently with the Snapdragon 820 as CPU so that TWRP and root will work with all T-820 all over the world or will there be different versions (e.g. Qualcom and Exynos)?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] basic086:
Sorry for the completely unrelated question, but how the heck can you get your hands on a tab s3 ? I live in Australia, been scouting the web and couldn't find anything. :(
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] suzook:
[MENTION=4899305]ashyx[/MENTION] deserves all the credit. He did all the work, I just flashed. It seems like all are Qualcom.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Just a question. I noticed in this recovery log you flashed the boot image patcher BEFORE Supersu instead of after.

https://drive.google.com/file/d/0BwPAGUQCA8FDN2pGWV9HSmdYNDQ/view

If you install Supersu on it's own without flashing the boot patcher do you still get the boot image not found issue?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] suzook:
I will give it a try. I am already rooted, Does that matter? Should i wipe, and redo?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
No need to wipe just restore the stock boot image and then install supersu. Thanks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] suzook:
I am a bit confused.....That .log is an earlier log, and I did try to flash both ways, and neither way worked. The only way to get root for me is use the last file you posted.https://www.androidfilehost.com/?fid=673368273298943936
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
I wanted to make sure that flashing the boot patcher before supersu wasn't causing the issue of SuperSU not finding the boot partition.

I have posted a bug to Chainfire, just wanted to ensure its a problem with supersu.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] suzook:
OK.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] CAL7:
Hello. I'm going to go a little OT here, but please cut me some slack. I'm following this thread closely because I'm needing a new tablet and the S3 looks perfect, but I insist on being able to root whatever I buy. My questions come from a long background in rooting, but I'm mostly a follow-the-recipe type of guy and all my recent experience has been with Sony Xperia's and Nexus devices. A lot of the terminology relating to Samsung rooting is beyond my comprehension. So...

With this TWRP 3.1 and SuperSU, do I get full root access?

Is it a permanent root or will I need to flash something on reboot?

What is Samsung's warranty response after rooting this way? If I have a hardware issue that no reasonable person would relate to the root, is it likely, unlikely, or a definite no-go that Samsung will help?

I don't think I care about Knox, Samsung Pay, Android Pay. Do I lose anything else that I should care about?

Given my limited experience level, are there unreasonable bricking risks (assuming due care and not being totally stupid) to try this?

Thanks much for your efforts to get this far and any advice you can provide.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] suzook:
[MENTION=4899305]ashyx[/MENTION] you might want to update op about broken camera with root.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Knight1314:
Can confirm, camera does not work with root. No FC message or anything, just a brief black screen with two buttons, then back to the home screen.

Edit: there is a brief message that sometimes appears: 'Camera keeps stopping.'

And here is a logcat output of the camera error:

http://i64.tinypic.com/whd0tf.png
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Try a third party camera app. It's likely a permissions issue. It has been reported to Chainfire.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] suzook:
No camera app works. I also found out auto rotate breaks too. What I have done is made whatever modifications I need/want rooted, then flash the original boot back, and camera and rotate is back, but obviously root is gone.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Gpsrisk:
Still stuck in the boot and stays there.

Any idea what i might have done wrong

also tried the 825 permissive boot and this time it boots and off and boots and off ...bootlooping....
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
It still doesn't work mate, something really messes with the wifi, not just remembering the connection, it seems to struggle to turn off and on for example for about 1 minute
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Was it the same issue on AQD6 firmware?

I'm surprised that app didn't work, it worked perfectly when I tried it. However I was only deleting the wifi connection myself, but as soon as I turned the wifi on it automatically populated the wifi setting and connected right away, both when rebooting and if I turned the wif off then on.

.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
This is interesting, that app just worked somewhat, but only when I clicked on the network name. I didn't have to enter the password.. Obviously still not ideal though...

edit.

I just have to open the wifi network list and it connects in fact.

tried it on a format and factory reset and the problem is there still. If I open the network list it auto connects.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Try adding the wifi fix to build.prop and see if it works better with that.

ro.securestorage.support=false

Ensure this is exact, no space at the end or anything.

If it already exists just change it from true.

By the way I have created a thread for the kernel. Let's move all discussions for it to that thread.

This one is going OT.

Thanks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Tried that with no success. The difference after flashing your file is, the WiFi also seems to start as 'Wifi OFF' (although it does eventually turn itself on) and normally it would actually boot up with the wifi connected instantly.
