[Q] Got a OTA update and lost root. Easy to re-root? - Galaxy S III Q&A, Help & Troubleshooting

Hi, did read on the website phandroid.com (sorry can not post the link because of spam protection) that there was an update for my i9300 and so i applied this update which indeed came pleasantly over the air. Although i got it rooted before with the help of Odin and CF-Root ... Would like to know if it's safe to use this method again to regain the rooted state of my phone? Anyone tried it already?

[Q] which way to root

Hi I was just interested in which way is best to root my device and why.
I broke my last galaxy s2 doing it via odin as I was unable to unroot it.
This time I have done it the superoneclick way and unrooted via ginger unroot app.
Yes I'm a noob and someone if any one answer will have a pop about which thread I should've gone to, but looking around for the last hour has shown bugger all.
I could'nt for some reason unroot with odin and am baffled why.
Any help would be appreciated
Regards Shaun
Root using one of the many root kernels.
Unroot by flashing a stock ROM from this thread: http://forum.xda-developers.com/showthread.php?t=1075278
Easiest way just flash CF Root via Odin. Job done simples.
Yes, I'm going to have a "quick pop". Initial search of Q&A forum turned up very similar questions, this is where you should have posted instead of creating a new one?
http://forum.xda-developers.com/search.php?searchid=8243020
Answers are above, including the link with guides.
Hi I did this the first time via odin, but was unable to unroot.
I used an insecure kernal and had the original kernal but when I flashed the original kernal back it was still rooted.
So this may be a silly question but why do I need to flash a rom as some people seem to suggest?
Sorry to sound thick ( I am I guess ) but so much info has really baffled me.
I thought you downloaded an insecure kernal and flashed via odin and that was it, rooted, then if you want to unroot you flash the original kernal, use usb jig and job was done.
Or am I way off lol
Again sorry if I am that bad
Regards Shaun
If you flash back stock firmware, busybox and superuser are removed, so you won't have root access. Also stock kernel as part of the package will instal stock recovery.

The actual rooting process changes (adds) things to the system, that's why you need to flash a "clean" one to unroot.
The unsecure kernels only provide the means to perform the root, they don't do the actual root.
Kernels like CF-Root or mine (see sig) do perform the actual root on boot, but as said above, it involves adding things to the original system.
First and foremost, thank you all for your info it is much appreciated and I mean that.
But I am totally lost and still have a screwed of G2 in the drawer.
I have followed advice to the T and some how I am no better off.
I mean what has firmware and roms got to do with rooting or unrooting.
I just want to get to grips with rooting before flashing firmware or at least someone to say what I did wrong.
On my new G2 I did it via superoneclick is that wrong?

Thats usually in most cases not following the relevant instructions .
This method works but if you cannot understand it then leave your phone unrooted and start reading the Guides and FAQS .
Root + CWM .
http://forum.xda-developers.com/showthread.php?t=1103399
Basics are choose your kernel flash through Odin phone is now rooted .
Ignore the yellow triangle or just buy a USB recovery jig to remove it .

Flash a fresh/clean ROM like suggested in this thread, that should most definitaly fix that phone and get it back to fully working state.
So just before I do this flashing the firmware, just to make sure you understand!
I do the flashing the firmware as if I was flashing the kernal?
Also I'm on 2.3.4 will it stay as that or will I have to use another firmware for that?
Again sorry if I am getting this wrong and thank you for your patience
Get a USB jig.
Flash your stock rom of choice from the intratech thread.
Flash speedmod kernel or whichever you want to gain root.
PS. You shouldn't be flashing anything if you don't know what your doing.....

The intention is to get the phone in a working state, so you can just about flash any official firmware you like. Your Android version will also upgrade if you flash a newer package.
Good reports about XILA2. May have a few Italian apps on it, you may wish to keep them or uninstall later. You may have to flash a seperate CSC later, or just manually enter your APN.
Follow Intratech's instructions and go for it!

JB ... ok, ATM there is only the leaked XXLSJ for our phone.
I recommend to flash CWM in stock recovery (=> http://forum.xda-developers.com/showthread.php?p=28178105 ... Method 1), then flash XXLSJ NeatROM Lite v4.0 (=> http://forum.xda-developers.com/showthread.php?p=35066742).

You would just boot into recovery and flash CWM zip file or boot into download mode and flash via ODIN.
This has already been discussed MANY MANY MANY MANY times already, there is no need for these "How do I flash" type topics no matter what version of Android is coming soon the process is same.

i9305 rooting error

Hi guys,
First of all thank you for all the awesome tips and tricks here, I really learned a lot from the community.
I have a samsung i9305 which I recently purchased to replace my i9300.
I downloaded super su and busy box to my phone but then they didn't work because my phone wasn't rooted (stupid me, i forgot)
so I tried rooting it using this method:http://forum.xda-developers.com/showthread.php?t=1914394
and followed each and every instruction perfectly but then my phone wasn't getting rooted (checked on rootchecker basic, although settings stated that my device is modified and triangle counter is 2)
so i did it twice but I still got the same result.
Then I tried this one: http://forum.xda-developers.com/showthread.php?t=1957273
And I thought it worked properly (since when my phone booted up it said that it was updating the OS)
but then my super su installation was gone and every time I try to open root checker it just gets stuck on the (your system appears to be slow...) and it never finishes checking. Also, sometimes the apps won't open.
Can anyone help me with this issue? I don't want to break/brick this new phone. :crying:
I'm currently downloading the original firmware and im hoping to unroot it by flashing it via odin later. But it's a zip file right and we need the .md5 thing to flash on odin? how do i flash it?
I hope you can help me out and I'm really sorry for the hassle.
Thanks in advance for the help.

By flashing a kernel like siyah v6 b5+ via odin.
Thanks for the answers!
Now first of all, ExynosAbuse would be perfect but does that support 4.1.2?
Also what comes to sidyah, does that support phones that are sim-locked? If so, how can i get rid of the operator sim-lock and is this risky?
And for the last: if i root my phone, can i get official updates in the future from samsung? Cause i don't wanna mess with the style that i got in my jelly bean quite like it, just want to get superuser-access.
So the app that i'm searching for is one click root that supports updates in future for 4.1.2. Is it impossible?
Thanks!
I'm with theunderling here.
I've always flashed via Odin woithout any problems and it very quick too. If you do everything right, it shouldn't take more than a minute, dead serious. 1 minute. Okay maybe more, but maximum 2 according to me
Just download tar or md5 file. Open Odin. Put the file in PDA. Then start. (and make sure Re-Partition is NOT checked)
(Im not going to give you step by step instructions cause that is for you to find out But i've actually helped you out alot
Good luck, and post for further question. Just dont forget to search before.
*EDIT* Yea, siyah is one of the best kernels, and dont worry everythin should be the same. You can get siyah kernel from gokhanmoral.com

[Q] [HELP] My S3-I9300 was in repair and came back rooted

Hey Guys,
Had a problem with my Galaxy S3-I9300, it wasn't charging, turning off on it's own, wouldn't turn on and etc.
I took my phone to a repair shop where I still had insurance. They fixed the phone and everything looked good until I tried updating my firmware, then I found out they rooted my phone without even telling me.
When I asked them why the did it they said that they changed some "electrical component" and without root my phone won't have any reception and internet (is that even possible?).
My questions are:
Is it true what they are telling me?
Can I still update my firmware some how?
Can I unroot the phone for the firmware update and then root it again?
Update:
I just got an update from the store that when they "fixed" the problem, the electronic number (IEMI?) disappeared and that's why they didn't have a reception, to get it back they had to use root.
How is that even possible?
I really appreciate your help, I really don't know who else to ask about this.
Thank you!

1. No, root has nothing to do with reception (Unless they changed your radio - which could be possible, but still nothing related to root)
2. Yes, use Odin and flash the stock firmware from http://www.sammobile.com/firmwares - you'll need to register.
3. Yes, but better to just use point 2.
Good luck!

Its simple. If your phone is rooted, and you have a custom recovery create a FULL nandroid backup and save it to your PC. Then read the unrooting thread and completely unroot your phone. First by running triangle away app reset your flash counter, then factory reset your phone, and flash the latest firmware available for your country(you can also cross check modem and CSC codes) via odin. All details are in the thread i mentioned. If the issues fixed by the company show up, reroot your phone and flash a custom recovery like CWM. Copy the nandroid backup to phone and restore. No harm done and you will find out if they are lying or not.
To update OTA you need to be fully stock and unrooted. Otherwise you can downlaod the firmware for your device at www.sammobile.com and flash via odin. As for your last question yes you can but there isnt much practicality in that.
