Unroot and reset to factory - Galaxy Tab S2 Q&A, Help & Troubleshooting

I need to reset my Tab S2 to return it. It may not go so well, since it has Knox tripped due to rooting it, but I'm still going to try.
I've got 5.0.2 on it, rooted. As well as TWRP 2.6.8. I didn't see a way to do this, so wanted to check: can I get the stock recovery back on the unit, as well as unroot? Or will be stuck as-is, with the most I can do being a factory reset?

Just flash the stock firmware to put everything back to stock then factory reset.

Knox remains showing "void", yes?
What about stock recovery?

Returning to Stock

Hello guys
I have a stock Rom dev. Edition with root.
I'm having some issue and wanna go back to stock. I can keep root as once I do like a factory reset, I will root again
I tried the factory rest from settings but it doesbt work. So I was gonna do a wipe from recovery but was worried I would end up without any Rom.
Can some one tell me the way to do it?
Thanks.

you should be able to do a factory reset through recovery without problem. the rom will not be deleted as long as you don't format the sd card/system partition..

There is still no way to do a recovery back to stock. This is the reason I have yet to purchase this phone. AT&T and Samsung have really screwed people like us. Keep it's posted on your progress.

If you reset the phone you will still be rooted, any apps you deleted will still be gone, it will delete any apps you installed. If you are on MI1 and want to go back to where you were then you need to find the Odin build for MI1 and use Odin to flash it. I am not sure what having SS on your phone will do if you Odin back but to be safe, if you have SS installed I would un install it.

So couldn't I just get the RDLV I originally used and flash it..? I think it was like 1.8gb because it included mi1.
I may even still have it.
So you say to essentially re-perform the RLDV procedure?

If you still have your RDLV it should work just fine. If you want true stock MI1 then you need to find that firmware and flash it in Odin. If you want to keep root then use your RDLV.

Soft Brick after Wipe in Safe Strap

I am new to the note 3 and did a full wipe in the 'advance options'...Coming from the s4 that was standard and it apparently soft bricks the phone here.
I am able to get to download mode. It just hangs on the Samsung screen.
Do we have the odin files for 4.4.2? I was on N900 I think. (Literally just got the phone so cant remember)
See if you boot into recovery by holding power, home and down key. If so download a custom rom on your computer and put on a sd card and try to install that way. Otherwise try to odin back to stock. Good luck

He said he's on 4.4.2, so he most likely has the A3 bootloader. You cannot restore back to MJ5 once you're on the A3 bootloader.
Looks like the only way is going to be Best Buy

im guessing carl1961 fix should be good for the ones stuck on a3 bl's but not sure. if you softbrick again after that then a reflash of nc2 is the way to go.

Let me guess. You wiped your stock slot clean then rebooted? LOL
You need to get with @carl1961 and he'll get ya back and running. Don't even think about the "restore to mj5" thread. You have the locked bootloader and it wouldn't work for you.

Ill try that if BB fails. I just want stock NC2 so i can root and safestrap away...
Cant believe I soft bricked a phone lol. This is like my 6th droid and ive never bricked b4.
At least im on MLG now. I bet BB can update it to NC2. I tried to sideload the update but it expects MLD.

I have no idea. I was attributing it to the fact i did a full wipe in advance. I cheeked all expect micro SD then flashed Dynamic Kat and the theme. Then it wouldn't get past the Samsung Logo screen.
Maybe it was an MD5 mismatch...

First, we're you useing Safeway? And are you sure you didn't have "wipe sd" checked.? Sounds like you need to do a full restore. Follow the instruction to a "t" and you should be fine.

you cant use the restore to mj5 method, different bootloaders. your best bet is bestbuy to reflash the official until somebody figures a method.

[Q] Rooted/s-on. Can I update anything.

Can I install stock recovery and then try to take a ota to update. Will I loose root and will I loose my rom? Will I be able to reinstall a rom or will I need to reroot?
you can try, you shouldn't loose root or anything but once you have unlocked and flashed stuff I doubt stock recovery will like your system enough to take the update. try this http://forum.xda-developers.com/showthread.php?p=53518227
HOW Change ...... ???
Sent from my SM-T217S using XDA Free mobile app
From my understanding, as long as /system is stock, you can install the stock recovery and then take the OTA. Afterwards, you'll need to re-root your phone. Make a backup of your current setup before you get started. Once you've taken the update and get rooted again, you can always restore your backup.

Must be the fact that I am s on. We need that s off before we can do anything as far as updating
This one is tricky. I flashed the stock rooted rom from mikmik, I then unrooted and flashed the stock recovery via fast boot. When applying the Ota, it fails because the build.prop is not stock. Comes back with an error like /system/build.prop unexpected.

I just tried it to and did the same exact thing except I had boot loops as we'll.
when I flashed back to the stock recovery to take the recent OTA, I had a reboot bootloop like every 2-3 minutes, I was ready to throw the phone against a wall, then it hit that I read recently someone else had the same issue, and mentioned a factory reset fixing the issue, yup after a factory reset, the reboot bootloop was gone, I just now rerooted and flashed a backup

yes, I was able to take the latest OTA, and no, it did not help with my signal at all, my device didn't drop calls or anything, but it has a hard time latching onto lte at times before and after the OTA.......

this might be a really stupid question (and my first post no less), but does performing a factory reset take me back to stock, unrooted form?
currently i am rooted with S-on, TWRP and Chainfire SU.
i followed a youtube video to root and im basically clueless with regards to doing anything more.
thanks in advance.

no, a factory reset will not unroot you, you need to restore a stock backup, then flash stock recovery in fastboot to unroot while s-on

Hey everyone.
I've spent the better of the last three hour scouring the inter webs, Google, and these forums trying to find the answers to my questions - but to no avail (I've found partial answers, but I am afraid a partial answer could lead to a total brick).
Here we go:
I bought one of the first Sprint HTC One M8's through Amazon. Here are the details:
Model: 831C
Android Version 4.4.2
Software Version 1.12.651.17
Unlocked but S-On (Using TWRP)
Naturally, right out of the box I rooted it. However, I did not save the original ROM.
* I want to restore the phone to its original state so I can accept the OTA update and hopefully address the god-awful cell signal.
I've found a lot of stock recoveries online, but none that match 1.12.651.17.
Do I need to find that specific recovery to flash to my phone? Will another one work (e.g. 1.54.654.13)?
I've never worried about saving my stock recovery in the past (been rooting since the HTC Evo days) but it looks like not doing so finally caught up with me.
Thanks in advance.
PS I did find something 1.12.651.17 related here, but how to flash this to my phone (or whether or not it will brick) is beyond me. I've downloaded all 6 files and am waiting to figure out how the heck to get them to my phone.
