Need to unroot Samsung Galaxy S4 Model SGH-I337M Bell Mobility for warranty purposes.
I am a newbie to rooting and a while back I followed the thread linked below and used CF-Auto-Root method to root my phone.
http://forum.xda-developers.com/showthread.php?t=2293800
Now I need to unroot it so I can send it in for warranty by May 5th, 1 year warranty will be up then.
I have done some looking online and think that I understand the unroot process is done by finding the stock Bell rom online then using ODIN to flash the phone. Basically the same way that the root was done using Chainfire's method only in reverse. I think using the method I did to root the phone it still has the stock recovery so is unrooting just that simple? Could someone please confirm if this is correct?
Is this all that needs to be done to unroot the phone?
Do I need to uninstall apps that require root?
Should I do a factory reset after?
Do I need to use triangle away after so that Samsung can't tell the phone had been rooted?
Thank you for any help offered, much appreciated.

K, thanks. Just to confirm I understand correctly, I need to do the process I described above using ODIN, then download rootchecker like you described when done to confirm that the phone was successfully reflashed. Sorry for needing to be spoon fed here, totally new to this.
Yes

Hi
I just got my phone, but missing the benefits of rooting.
Can anyone tell me how to unlock the bootloader and then root my phone?
Found a lot of links, but not sure which are secure and not to use.
Here's where you go to unlock your bootloader - http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Once unlocked, you can flash root or do whatever at that point.
Warning though, you will lose your DRM keys in this process, if you don't know what that means, do some research

Is their any way to back them up? So if I ever regret, I can get them back?
Also, is it possible or will it ever be possible to root with an locked bootloader?

You need root to backup DRM keys.
You cant get root without unlocking the bootloader yet.
Youll lose DRM keys when you unlock the bootloader.
If you cant take losing your DRM keys do not unlock and root.

Last question. I got Samsung before and I was able to update my phone with Kies after rooting. Is their any way to update Sony devices when rooted?
Thanks
Flashtool or PC Companion. I prefer the latter.

You sure? As the DRM keys doesn't matter for me, as I don't really use the camera a lot.
But when I unlock bootloader on Sonys website, it tells me I would not be able to get updates from that. But i'm still able to get them with the PC companion?
Just to make sure, as I really want android 5.0 when it comes out.

You can't update with PC companion if you have unlocked your booloader. Your phone will be bricked!

No way to know for sure until someone tries. But with the Z2, you just have to relock your bootloader (might need to revert to a stock kernel first) and then software updates work fine.

YES, it can be done. NO, we can't tell you how because you didn't post your phone model or Android version.

Hej robogo1982, jesi dobio moju poruku u privat?
Hello!
I bought a phone, with unlocked bootloader and root. Z3 D6603
I dont know exactly how the previous owner unlocked BL etc.
But I flashed it to 23.1.A.1.28 lolli, fixed super SU and dualrecovery.
The thing is, I now want to return it to stock, so that i can get OTA updates by Sony Companion, and i have no idea how to do so.
Searched the forums, and found a lot of info, but I dont want to brick or ruin anything.
Do I need to flash stock firmware without root, remove dualrecovery or relock BL, or maybe all of it?
I posted this earlier, and im not sure if I explained it right, I said I wanted a step by step guide.
What I meant was a guideline in what ORDER to do stuff, not how to do them.
Is it enough to relock the bootloader, and then use Sony Companion to update, or do I need to flash something, maybe go back to original recovery first?
Help is sincerely appreciated !
PS: Sorry for posting again, but I dont know how to change the headline/bump the post, and need this done ASAP, or else I wont have a working phone in a few days. ( Change of sim card)

Nothing. If it is unlocked and you dont have backup of original TA partition. There is no help. You can't get you DRM keys back and without them you cant relock to original state. And majority of Sony stock fw simply doesnt provide OTA for unlocked bootloaders, except for the new Sony Concept ROM.
You may try to download Androxyde Flashtool as it provides relock function, however it doesnt restore TA. If it brings OTA back not sure, because I always backup my TA so just try it.

Hi peps,
I just switched from my crappy HTC One X to my new Moto G3 and I'm in love!
I don't really want a custom ROM, but I'd like to undervolt this babe. But since a root requires unlocking the bootloader = voiding the manufacturers warranty, I don't really wanna do that..
I've bought it over Amazon and I live in the EU, so I technically still have the retailer's warranty and Amazon would replace it without a hassle, but yeah.. it's new and all.
But I know there are apps like towelroot, KingRoot and what not, do they work with the Moto G3? I'm on 5.1.1.

Thanks for this unnecessary input. :good:
On previous versions of Android there were exploits that allowed rooting the phone without unlocking the bootloader, which means you could keep your warranty and I just asked if it works on the current Moto G3 with Lollipop 5.1, why do you have to be such a smartass? It's a normal question, why can't I have a normal answer?
I used to root in one click in just one method on my previous phone xperia sp but i dont know this phone have any toll which will work or not?

Being a smartass is kind of my thing.
You're afraid to unlock your device's bootloader because you'll lose the warranty, but you're perfectly fine with risking the security of your device by rooting it, right? Seems odd to me, but whatever.
Generally speaking, both KingRoot and TowelRoot are used on devices where using those two methods are the only way to root those devices.
Unlocking the bootloader will have no ill effect on your device other than voiding the warranty, and, if you're worried about voiding your warranty, you shouldn't be trying to modify your device.

Just unlock the bootloader and flash supersu for root.

Who said I'm afraid of unlocking the bootloader? Who said I never unlocked the bootloader of other phones before?
I just don't wanna lose my warranty in the first two or three months, in case my phone breaks unexpectedly, I also don't plan on using custom roms, I just want the root features so I can undervolt like I said and IF I could root it permanently without unlocking the bootloader, why not?
I'm not worried, it would just be convenient to have root without losing the warranty, that's it.
As far as I know you may be able to do it search kingroot in Google then download the apk and install it then open in and follow the instructions

Then leave the device stock ...
If you want the best of both worlds (root & warranty), then go buy a Nexus. Motorola drew a line in the sand as to what they will support, while still empowering owners with the option to unlock the bootloader.

Not really. While I've unlocked my previous phones, my new g3 I'm leaving locked for the first year, while the warranty lasts. But this site still has a few helpful stuff.

He just wants the warranty, but he doesn't care about rooting it because there's not really anything wrong with rooting if you know what you're doing and how to fix it.

Towelroot is exploiting a bug in the Linux Kernel in order to root a device. This bug was already fixed in June 2014.
On all Kernels with a later build date Towelroot will most likely not work.
For sure it will not work on the Moto G3 with a kernel build date more than one year after this bug was fixed.
Thanks!

It's probably been answered already but those exploits are security flaws with the SE Linux system and so with each release of android these have been patched, by 5.1 these security holes have been fixed and now by locking the bootloader
It's like just locking down and modifications to the system partition so unfortunately you can't root without unlocking, unless you have android versions lower down

What version of TWRP did you use coz I know there were some bugs on the moto range with TWRP 2.X.
I would completely wipe device using stock recovery, including dalvic/cache/data everything just to be on the safe side, then download the TWRP zip to your computer and flash it on using ADB.
Boot up normally and move the superSU zip from the link to your phones internal storage. Then reboot to TWRP, select install and pick the zip file.
superSU.zip:
http://dl-1.va.us.xda-developers.com/3/6/5/5/4/0/1/BETA-SuperSU-v2.62-3-20151211162651.zip?key=u0OeGV4-4s02KJXqrXJ-gg&ts=1466705675

Perhaps you can offer wisdom on this? I rooted my Moto G 3rd Gen once, wrecked something and had to go back to factory, then try to reroot again. Problem. No matter what I do in setting the device back to factory, the bootloader stays unlocked and reads the system software as "modified" which then seems to bork installing SuperSU. I install SuperSU via twrp and it goes fine, no errors, but when I reboot the system is lost in a loop of the "bootloader unlocked" screen.
So I cannot RE-lock the bootloader (ala setting the phone back to true factory) and after I flash SuperSU the phone refuses to successfully bootup.
Any aid? Ideas?
I had failed to backup my phone the first time with twrp and so to set to factory I downloaded the stock retail xml.zip for my phone and reflashed the entire thing via fastboot. Reinstall twrp, and try to root and the endless boot loop begins.
So I came to this thread to look into the possibility rooting my phone via another means that MIGHT work.
Please i need to know, recently i bought an Xperia Z5 Premium, but i want to root it, will i still get OTA updates?

If you use systemless root, you should be able to take updates; you'll have to unlock the bootloader and flash a custom kernel. Take a look at either SuperSU or Magisk.
Why would you need OTA, just flash newest version with flashtool and that's it.
And the most easiest way to root, is to :
unlock bootloader, flash latest 32.2.A.5.11 firmware using flashtool, and then flash patched stock kernel( twrp included), and flash latest supersu using TWRP (it will be installed systemless). Cheers
You won't receive any OTAs once you unlock your bootloader.

As far as I know, there is currently no way of rooting Xperia Z5 without unlocking the bootloader. If you decide to do so, don't forget to take TA backup before doing it.

BACKUP DRM KEYS BEFORE UNLOCKING !!!!! Just in case anything goes wrong and you need to take your phone to service center (so you won't void your warrenty)
