Can someone please give me a run down on how to remove root on the Tab S2 8.0? I've tried to flash the stock firmware in Odin but it fails every time. Im not sure where to go from here. Thanks!
Use the uninstaller in supersu settings
Thanks ashyx. I did the unroot in supersu settings but my s2 is still saying "the operating system has been modified in an unauthorized way" when I try to update. I guess what I'm looking to do is completely go back to factory state.

flash stock firmware with odin

I was rooted and running CM6. I tried getting back to a stock 2.2 by flashing the stock image from Rom Manager. I downloaded the 2.2 update from google and it wouldn't update. In the system menu or bootloader I got a little format happy with boot/system and so on. Anyway, doing a nandroid now. Is there anyway to get this phone back to the kernel it shipped with?
You have to flash it with the stock recovery.
I've been using that Universal androot.http://www.androidappjudge.com/2010/08/one-click-root-application-universal_10.html I tried flashing stock 2.2 and I didn't read the two options, I just clicked them and kept going not realizing that I flashed the rooted, superuser version. Does this mean that I'm now rooted forever? When I try flashing stock 2.2 with rom manager It stops @ the android and /!\ symbol. Now it's even doing this with CM.
I'm now wondering how to get rid of whatever crap might be floating around on my phone and why it may not be flashing anymore?
there is nothing wrong, rooting allows you the ability to have super administrative rights. Since all you have done is grant yourself admin rights, the recovery should be the same.
Something is wrong. I can't Fix Permissions or flash anything.
Man, I should have just left it alone.

Did you wipe? I used 1-click root and I hadn't flashed anything in over a year so I forgot to wipe and I boot looped until I pulled the battery, booted into recovery and wiped. Simple solution but it could be worth mentioning...
So you are saying that, you have the stock recovery now? Triangle with little android? If so, Just download a PASSIMG.zip and flash through bootloader. This will take you to stock.
I have an N1 with locked bootloader and when I wanted to go back to stock(Forgot to get a nandroid of unroot rom). I had to flash a stock recovery. then downloaded the PASSIMG.zip from here http://forum.xda-developers.com/showthread.php?t=717870&highlight=frf91+downgrade
This takes me back to ERE76. Then I download an OTA of FRF85B.
I think fix permissions fixed everything. Thanks for the tips!

TWRP Recovery
Rooted
Xposed framework installed
Been getting bugged for the 4.4.4 update, and I wanted to open and look at the ZIP out of curiosity, so I hit install now, thinking it still needed to download... but turns out it didn't, and rebooted right away.
So now I'm stuck in a boot loop of sorts.... it boots, and loads up Android, and I can use the phone, but after about 20-30 seconds it reboots into recovery.
Is there an easy way out of this without wiping everything? Preferably a modded OTA that I can install for the 4.4.4 update.
Check out the thread under general tab to use RSD Flasher or House of Moto to install the 4.4.4 FXZ

The above post is good advice. If you use House of Moto with the full 4.4.4 FXZ, you can choose to "KEEP DATA".
You will need to flash TWRP back on and re-root afterwards AND re-install Xposed, but all of your apps and settings will remain intact.
The reason this happened is because you have TWRP installed - taking OTAs *always* requires you to have STOCK recovery - not custom.
Good Luck :good:

Thanks for the replies. Thanks for the reply... the phone eventually decided the update failed and gave up. Apparently clearing the cache would've also probably worked.
But, now I've reflashed stock recovery, removed xposed, and unrooted. I should be safe to just take the OTA now, right?
I would've done the FXZ earlier, but didn't realize there was a keep data option.

You can try, and it will probably work....but if it were me, I'd still use the FXZ and keep data option. It's cleaner and no chance of something going wrong. Afterwards, just do like I said -- re-flash TWRP, re-root, then reinstall Xposed.

Great!! Glad to hear everything worked out. I sent you a Private message - check your PMs
Just to add my experience: I too tried to apply the update (rooted, 4.4.2, xposed, stock recovery, locked boot loader).
Got the boot loop you mentioned.
Only remedy was for me to quickly go into root explorer and rename the 3c.ota.apk and 3c.ota.odex files. Now I no longer get the notifications (unless I reboot my phone).

And in your case, it was Xposed.
There are several threads (and posts) discussing conditions for taking an OTA. You need stock recovery, have to disable Xposed, and you need to be close enough to stock so the pre-flash verification will pass. Otherwise, the OTA will fail, and/or you'll get stuck in a boot loop.
There is a little more to it as well, but I'll ask you to see the other threads.
Thought I disabled xposed. But perhaps not. I've read other threads. From my understanding, I won't be able to root (or even the quasi-root) on 4.4.4 with a locked boot loader.
Thx for the reply.
Hello, I'm terribly sorry if this is the incorrect place to put this; but I'm desperate. I flashed hyperdrive on my galaxy s4 active NH3, and it booted the rom before I could flash the master patch, and the su update zips. So now im stuck with an unrootable nh3 galaxy s4 active that runs hyperdrive rom fine, but my wifi doesn't work, and I can't get into safestrap to flash the modules, because I can't root to install safestrap. Someone please help me, I can't reinstall my stock rom with Odin right now because my computer isn't working. Please help and thank you so much
The safe strap splash screen doesn't show up at boot? A safe strap ROM should not uninstall safe strap iirc.
Just because the app isn't in your app drawer, doesn't necessarily mean safe strap is gone. Reboot and check if it's still there, it should be.
The splash screen doent come up at all. It just says "samsung galaxy s4 active" and where the ss screen should come up, it automatically boots into the rom, displaying the rom boot animation and booting into the rom

Every single solution I can think of either requires root (lol hardly a solution, huh?) or consists of, "Odin back to stock." Are you able to use Odin at all?
Even if you don't want to Odin back to stock NE3, I think the W0lfdroid method should still be able to root your phone while on hyperdrive, just like on stock NH3. I.e. flash the root kernel to your phone via Odin, boot and run towelroot, Odin flash the NH3 kernel, boot and install/run superSU.
I'm inclined to think that method will still work because for any rom to work on the i537, it automatically has to be compatible with our stock kernel.

Thank you, ill try that method. I wont be able to get my computer fixed until the weekend so im suck with no wifi or camera until then. Im still very confused as to why it did all of this. When I flashed the rom in ss, the aroma installer launched, and at the end I pressed next and it froze, so I had to take my battery out a place it back in. When I rebooted I expected to see the ss splachscreen so I could proceed to flash the masterpatch and the camera and wifi fix but it just booted right into the rom boot animation and then loads the rom. It continues to do this, so I have no safestrap now. However I do have the safestrap apk saved on my sd card along with the towlroot apk incase I ever lose root while flashing a rom and my wifi doesn't work such as the fist time I flashed hyperdrive with my NE3.
Anyways thanks a bundle
Classic case of bootlooping.
Recently used Flashfire to install rooted stock version of Lollipop 5.0. After trying to reinstall X-posed framework by flashing through flashfire, phone became bootlooped at At&t logo, remaining bricked after factory reseting and clearing cache.
Used odin to try and downgrade back to a stable version of 4.4 kickat. However, phone now bootloops after shuddering at samsung logo, before blipping to black screen with blue indicator light permently on. Trying to install current version of OTA rom through default recovery made no change. Suspecting bootloader my be root of issue, as trying to flash stock version of 4.4 bootloader in odin fails.
Currently looking for options to simple get phone back complete factor reset at this point. Links to other threads that have already solved this problem welcome.

If you installed the 5.0 rooted then I'm guessing you seen this thread. If you have the s5 then scroll down to the notes section and flash the nce downgrade file in odin. That'll put you back to stock.

Flash in odin 3.09 in the ap slot
Don't flash this file if you took the ota to 5.0 or if the phone came with 5.0 on it. You will brick the phone.
Hello
When i use the ODIN file it flashes and passes but it is not installed? It just boots up in stock recovery. I have the G800F. Can anybody help?
It's this one i try to install. http://forum.xda-developers.com/galaxy-s5-mini/orig-development/recovery-twrp-3-0-0-t3313775
Download Flashify from the Play store and flash the IMG :good:
What ROM?
If you want to stay on stock, you must disable security updates and Knox or it may revert recovery to stock, I guess. At least in first lollipop versions with 1GB kernel. If you don't just boot to recovery after flashing recovery.
I am writing a guide - i got it to work thanks guys
would be great if you could post just the steps, I got the same issue :-/
