[Q] How to unroot my device (which using stock ROM)? - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I'm using the stock ROM for my device (v. 2.3.3).
I've rooted it, several months ago, and I don't remember, how did I root the device.
How can I safely unroot the device, without re-flashing the stock ROM again.
I was wondering if there is a simple method for that.
Thanks,
Amir.

Flash the stock kernel via Odin and not CWM but it'll not remove the yellow triangle if you flashed CF-Root.

To remove that use a JIG or reflash the stock ROM

Hi,
I'm looking for or wondering, if there is a solution that doesn't need a re-flash of the ROM/Kernel.
Something like one click unroot... the easy way

[Q] Rooting issue!

Hi guys, I have had my phone for a few weeks now and I'd like to ask about a little problem I have been experiencing. So, I just rooted my device this morning and flashed the new ICS ROM. Though, I realised that I prefer MIUI. So, when I loaded recovery to flash my new MIUI ROM, I was greeted by a blue 'CWM-based Recovery v5.0.2.7'
I don't understand this because when I rooted this morning the recovery I had was a different version and it was orange.
What I need to know is the steps I need to take to flash a new ROM from scratch. Do I need to go back to the original ROM, then re-root? Do I need to re-root at all even?
I guess I'm still kind of a noob, so any help would be appreciated and I will click that 'thanks' button for anyone who gives a good answer.
Thanks in advance, Joe.

CWM and root are not directly related.
CWM comes with the kernel.
Root is part of the rom.
Miui will be rooted when you flash it.
You do not need to be rooted to flash roms via CWM recovery.

What do you really mean? from where are you accessing and what?
Why you want extract...? for removing any specific app?
If you have a CWM back up of earlier ROM, you can use Titanium Backup Pro for individual apps installation for installing from your earlier ROM....
I just wanted to do it in case I would like to back up to original state before rooting and flashing CM7.

Sorry to say you cant backup your current ROM till you root your phone...
Use checkfus to download original firmware .

If you use CWM you do not back up original as it has cwm and root kernel ,

Ok, I have back up my phone just after root so I have possibilty to back my stock T-mobile brand firmware but with root.

is it safe?

You can't update any rooted / superuser modified phones thru Kies.

As long as the ROM & CSC are correct you can update a rooted phone through Kies, as far as I am not wrong, whereas you will loose root and have to re-root. What is not working is the OTA update if you are rooted.
Hence the easiest solution is to download the ROM via sammobile or XDA and flash it via Odin or better Mobile Odin (to keep root).

No, you can't. I've tried myself and it doesn't work.

Yes, you can update a rooted phone through Kies as long as the csc is correct. You will lose root though, but other than that it's safe.
thanks guys for immediate response.I think i will just use odin to maintained rooted. my only problem is i am not sure what guide to use and which is safer? although i research myself through i am just confused so many guides in using odin. my phone is GT - I9300 android version 4.1.1 with a baseband ver: i9300XXDLIB. i just want to update this to 4.1.2 if possible via odin to maintain rooted. If you guys can help me out which guide to follow that will maintain rooted and safe that will be much appreciated!

As I mentioned, Mobile Odin is the easiest way as you just select the rom and it flashes incl. root injection. For Odin, simply download the rom you would like to flash (e.g. stock rom from sammobile or prerooted from XDA's general section), and follow the usual steps (e.g. there are easy videos to follow on YouTube & there are many guides in the general section). If you chose to flash a rom that is not yet rooted you will need to flash CF-Auto-Root of CF-Root again.

got it! another question if you don't mind, can i use stock rom using odin without unrooting my device? some people say that if you try to flash your device with official stock rom might unroot phone? is this true or just using odin will prevent your phone from unrooting? no matter what rom you would use. thanks in advance!

there are two ways:
(1) Odin (desktop version): if you flash a stock rom (normal version, not rooted), it will be not rooted, hence you have to root again
(2) Mobile Odin (Adroid Play Store): if you flash a stock rom (normal version, not rooted), you have an option to inject root and directly root it in the process of flashing the rom

I see, the mobile odin i guess is suited for me. since i dont want to unroot my device i just want to update it.
you can always reroot it afterwards. Or better yet, flash a prerooted ROM

[Q] How to unroot galaxy mega 5.8??

So i rooted the device using odin 5.0.7 and saw that i cannot update my O.S
Can anybody give me a step by step instruction on how to unroot my device or if there is any way to upgrade my rotted device??
P.S-I am a newbie and i know very little about such things
If you have superuser by chainfire then you can unroot using the app itself. Otherwise download and flash via odin any stock firmware to unroot. Better still flash the latest stock instead of ota updating.

If you want root you are going to have to flash the new Roms as they are released and not try OTA anyway. If you want stock, that's fine, but you can't do much around here with a stock Rom.

Thats for i9205 my model is i9152

i9100 Rooted but no CWM

Hello everyone, greeting from Turkey!
First of all im a newbie for android rooting and romming etc. I ve always used stock roms since ive got this phone. Now Im running a I9100 (int.) with stock Turkish 4.1.2 (XXLS8) on it and i ve rooted it via superuser.zip with my stock recovery.
What i want to do is to install CWM and want to flash a RELIABLE and Long Battery life rom. Are there anyways for me to install a CWM without using odin (via stock recovery). And can you please suggest me a good rom for daily usage. (i want to use vanilla android btw [just like nexus]).
Thank you for your helps.
I don't know much about roms/kernels for the international version, but you will need to flash a stock kernel with cwm and then just choose a rom from your development thread and follow the instructions, don't forget making backups and reading a lot, you can start from flashing cyanogenmod.

As i said i dont know about international version kernels, but it should have a tag like "stock kernel" or something like that if its for stock, just install it and you will have cwm, if its not stock it wont be installed anyway.

You can flash a kernel for stock roms via stock recovery, you don't need to use odin, just read the instructions.
