updating a rooted Galaxy S2 to android 4.x - Galaxy S II Q&A, Help & Troubleshooting

Hi there,
I have my rooted I9100 (su binary v3.0.3.2) still running android 2.3.4. I think this is time to update to 4.x (JB is the latest available I guess) but after some research I couldn't find the firmware from a trusted source (since I have to perform the update manually due to root). Could anyone help me out? Some instructions would be nice too. Thanks

Sammobile.com (or JB thread sticked in the general forum) and flash with Mobile odin Pro.
Don't wanna pay for the pro version?
Mobile Odin Lite.
It doesn't get any easier than this.

thanks. Just flashed and everything's working fine. One more question: is there any way to remove all the pre-installed bloatware?

Yes, see @Sun90's post about which apps are safe to remove. And you can use titanium backup (from play store) to freeze/uninstall the apps you do not want.
Edit: gastonw beat me to it..

Freeze the apps first.....in case you mess with something you shouldn't. And make a nandroid before you start....that way you always have something to 'fall back' to if you freeze/delete something that the phone needs to boot .....

thanks @ all. I just found the Root Uninstaller Pro and removed everything I was sure that will not damage the system, like those Hubs and some carrier specific bloatware. Seems to work fine

Getting Root without deleting data. Possible?

Hello. Is it possible to get root on Samsung Galaxy S3 with no data deleting and no flashing new ROM. I just want to save current pre-installed stock ROM?
No because most Rom's these days require a full wipe unless stated....follow the procedure in the S3 Android Development section in order to root your device....new process is available, easier and quicker

Root using this -CF-Root- method. I'm quite sure this method won't wipe your data. OTA updates are not available on rooted phones.
I followed this guide
http://www.androidnz.net/2012/06/at-your-own-risk-how-to-root-your.html
and rooted my GS3 without loss of any data at all. Everything exactly where I left it when I rebooted..... it was still a bit scary messing with £500 worth of phone, so that's why I did it within the 7 day period where I could take it back to the shop for an instant replacement
I see.. And how to get new stock updates on Rooted phone? What will you say about http://www.sammobile.com? They offer paid services...
Mate, any new firmware will be picked apart and put back together about 1000000 times better by our devs here on XDA... Look at all the phones we play with.. I have been using this site to hack my phone for years and I can tell you that the roms the devs cook up here are light years ahead of what most companies do...
Anything that appears in the zoo will make it out here to the wild sooner or later....

you can get root without loosing any kind of data or config with the stock rom!
just follow this thread: http://forum.xda-developers.com/showthread.php?t=1684535
and do exactly what is written in the sections "Instructions - Long" and "Manually rooting" - you will than have root with the stock rom - no need do change firmware, rom or kernel and no need to do a factory reset! I've done that yesterday, and didn't loose any configuration!
cheers Gerald
Thanks Gerald. Guys, what about getting new versions of stock firmware after rooting the phone? Is it possible without deleting data (something like OTA)?

What the hell are you talking about? ofcourse it's possible.. I did it..
You flash the insecure kernel with Odin, then you push superuser via adb.. it's as easy as that.
It doesn't touch the data partition.

You can't get official updates from Samsung with root, but you can flash the updated software via recovery (and I'm guessing odin - haven't got much experience with that since its my first samsung) without wiping data, thus only updating the system.

[Q] Galaxy S2 Root

Hi all,
New to all this. Have performed a root using the instructions here. Thanks lyriquidperfection
http://forum.xda-developers.com/showthread.php?t=1125414
Seemed to work ok, just installed first insecure kernal on the list without matching to my kernal, it installed Superuser but not Busybox, so installed that from the market.
The reason I wanted to root it apart from 4.0.4(needs to be rooted?) coming soon was in the hope I could get shot of some of the locked apps Samsung and Google installed on it. Busybox looks to me that you need to know what you are doing to use it. So the question is is there anything simple I can use to get rid of the locked apps that I don't want?

Wonder why they make it so complicated, most of the pre-installed stuff is a lot of tosh, then again so is the Market stuff

Just bought S3 and want to ROOT and install OTA 4.1.2, possible?

Hi Guys,
I just bought a new Galaxy S3 here in New Zealand and before I start using it, I want to update it to the latest version, I believe 4.1.2 and then root it, can this be done? whats the best option for me? I see the Galaxy Toolkit to do the rooting, is this the most popular/best ?
Also after rooted, can I still do the OTA updates or will I have to flash custom roms?

If 4.1.2 was not yet launched in NZ, then you will not get any update for your phone at the moment.
What you could do is, root your phone and then install the 4.1.2 version (Poland)(root is not required for flashing though). For rooting refer to the stickies in general section. Popular methods are CF-Root 6.4 (incl. CWM as recovery) or CF-Auto-Root (keeps stock recovery) (both can be found in dev. section).
After rooting you will not be able to get OTA updates though, whereas KIES should still work (but you will loose root if you update).
In addition, make sure to read all the stickies and guides for rooting before you touch anything! Especially the EFS backup procedure.
I hope it helps.
Rooting your phone voids it from getting OTA updates.

As said above 4.1.2 is still not available in NZ. So you can flash other ones (like Poland) if needed.

After rooting OTA updates will not work. But you can still get the firmware and flash them through Odin. This will remove root and will have to go through the rooting procedure again.
I feel samsung will release 4.1.2 for other regions soon and my suggestion would be to wait for that and then go ahead with rooting
You don't need to root your phone to install an official firmware!

Thanks guys yeah 4.1.2 does not look like its been released yet, I'll wait for it to come out then root cheers!
I used to wait for offical releases, then realised there was no need - the custom ROMs are far better than the official and much faster at new releases than regional Samsung rollout. They also get rid of the battery sapping bling most people only use the once.
If you are going to root anyhow, then the warranty isn't a concern.
Just had bad experiences with 3rd-party ROM's. Had a Desire Z and ran about 5 different roms, cyanogen, gingerbread and ICS variants, mimcry, ilwt, extreme mod, and none of them seemed to run very well after a few weeks of use. The stock ROM on this galaxy is flying like no tomorrow! especially after simply disabling the garbage apps

I'll admit that Samsung could teach HTC quite a few things about writing a good ROM, I'm sticking with customs of the stock jb 4.1.2 for now as it all works so well and saves me having to remember what needs disabling. I tried a few minimalist roms before sticking with the viking one.
I've got a 4.1.2 in NZ but that's because my phone bricked and they updated it when fixing it(4.1.2 supposed to have the fix for bricking)

[Q] Just Rooted my JB 4.1.2 (XXELKC) What Next?

Hi,
I just rooted my S3 JB 4.1.2 (XXELKC) so what is next?
Any recommendation to make use of all the benefits of Rooting
You can Install Adfree, Go Backup or Titanium backup and make a full backup of your data, First go to Recovery (CWM) make a full system backup.
After that you may wish to try some Custom roms, CrDroid or Wanamlite or Foxhound they are very good ROMS.
If you do not know what for are you rooting your phone - do not do it.
Most likely, your base benefit will be:-
- loss of stability due to overclocking;
- loss of functionality due to app freezing in TB;
- worse case scenario: phone brick.
sorry mate but your post looks like:
I just have removed all the fuses in my house, and I replaced it with rigid cable, so what should I do next?
If you do not know what for are you rooting your phone - do not do it.
As the man says root does nothing .
You root for a reason and not if you have no reason .
You would be far better off reading the basics in the stickies before trying to do what you know nothing about and risking a bricked phone .

First Phone I rooted was the the t-mobile G1. I had no idea what I was doing at the time... We all have to start somewhere...

You can install apps like adaway or such as stated above. I just want to tell you one thing. Naturally you will be curious to use custom ROMs like Ultima (it's really cool) or such. But before trying each different ROM have a Full Wipe.
May take a look at this thread:

Use Google my friend. Lots of bennies but I agree with JJE. Best to know why and what for.. before doing anything
Also please in the future ask Questions in the Q&A section.

Thank you all for your replies. My main reason to root to try different apps that require rooting. I don't think anyone when started rooting his/her device knows everything and what to do without referring to some help from forums of reading somewhere.

Sorry, but... actually I was acting contrary to that. I rooted my SGS two years ago first time to freeze/uninstall bloatware and to ban some apps from net usage, or to limit its net usage to WiFi only (by the use of Titanium Backup and DroidWall, respectively).
Unfortunately, DroidWall needs the root all time while running, otherwise, I'd unroot device as soon as I finished cleaning.

I first rooted my LG GT540 so that I could flash a CM7 port, best choice I ever made.
Now I use it for Titanium, root explorers, adfree, getRIL , fasterGPS, multi window control and to obsessively flash roms mainly.

[Q] Managed to successfully root But... Some Q's

Hello, I have a S3 I9300. Came with 4.3 Pre Installed.
Now I have JUST Rooted it and removed some useless apps.
Now my questions is: IF I want to do a factory re set.
A) Would it work?
B) Would it work and go back to Unrooted or stay as Root?
I am looking for a Simple Stable/FAST/Smooth/Stock Like ROM. Any recommendations.

Yes the factory reset will work and after that you will lose your root access, but you can easily gain it again with https://towelroot.com.

Ditch touchwiz and try a different launcher and it will be even better.
Also be warned asking which roms/kernels are best etc are against the rules.
