if you wan't to upgrade you don't need to unroot, just flash firmware trough odin (addicted to your country)
also to unroot just flash with oding (stock firmware) and wipe data/factory reset and done,
threads are everywhere in general just look around

Since this topic is started might aswell use it instead of making a new one...so my question is:
From what I've read, in order to install CM7.2 on a Galaxy S2, you also need to install a custom kernel...so if I did all that, and want revert back to my original ROM and kernel, I just flash a stock ROM from Sammobile? Or the Kernel will remain the custom one (if so, how do I change it back to the stock one)?

Nope your kernel won't be left until you flash a Rom which has no kernel, but all Samsung roms out there have kernels inside the flashable tar or zip, you ain't smart if you don't provide a kernel which is made specially for the Rom

Cannot flash stock rom = cannot update, need help!

I bought my S2 last January, and even that I didn't really care about rooting, I've came across these " Make the best out of your s2" articles and I decided to give rooting a shot.
I managed to root it and flash insecure kernel on it and everything was alright. However, I've heard that ICS4 can only be updated via KIES if I'm not on Root/insecure kernel, so I went ahead opened the application " S2 Root",and unrooted successfully. Nevertheless, I wasn't able to get rid of the kernel, which is perventing me from updating.
I've have searched on the forum, and I came across an article suppling stock roms, but it was all on multiupload, which is down since a while.
I'm aware that I can update to ICS4 using odin, but I'm more into the official way since I didn't really see a reason in rooting ( after I did ), well I'm certain it's because I'm just a casual user, who wants to call, or just play with some apps.
Some Info about my phone:
Samsung Galaxy Sll ( Of course )
JPKF3 Built!
I'd really appreciate if someone can link me to the above stock rom ( I've searched and find none), or just tell a method where I can remove this kernel in any possible way.
Much appreciated, and thanks in advance.

Unable to upgrade Android 2.3.4 to ICS

Hi,
I purchased Samsung Galaxy S2 I9100 from US. Now I am in India and my friends have updated their S2 to ICS but whenever I am conecting my phone via Kies it says that latest software is installed on my phone.
Details are:
PDA: I9100UHKI2
Phone: I9100UHKI1
CSC: I9100UUBKI2
Android Version - 2.3.4
Build Number - GINGERBREAD.UHKI2
Please senior member help me.
I don't want to root my phone.
Thanks in advance.
I dont think either you will send your phone back to US for any Waranty purpose or you will get an USA phone waranty in India, then what you are waiting for??
root your phone with Custom Kernel+CWM and install a ICS rom from CWM,
or flash the ICS rom from ODIN manually.
Root + CWM : http://download.chainfire.eu/40/CF-Root/SGS2/CF-Root-SGS2_CE_XEN_KI2-v4.2-CWM4.zip
official thread and Guides for flashing : CF-root link in my signature
Dude, if you really want ICS on your phone- Root It ! Because if Kies says that there are no updates available, you cannot help with it. Go ahead read one of the guides, and flash an ICS firmware via Odin- it does the trick. Even i was afraid of rooting my phone and flashing it- i thought it was dangerous. But dude, trust me- i was wrong. It has absolutely nil chances of something going wrong with your phone if you follow the instructions. If you root your phone , you can even get better things like Custom ROMs and other stuff which is absolutely brilliant and which you can show-off to your friends! Trust me , i've been through this. I was facing the same problem when all my friends on Galaxy Note got ICS, and i didn't. All i did was rooted my phone and put an awesome custom MIUI ROM on it. Now i shut their mouths hahah
So, go ahead- start HERE Just read everything carefully, make up your mind, and i'm sure you wont have any troubles rooting your phone. BEST OF LUCK!
Please press the thanks button at the end of this post if you found it useful !
Cheers!

As ZACQ8 says you wont have a warranty with it but rooting is up to you.
Go here http://forum.xda-developers.com/showthread.php?t=1075278
Download Odin, then download the latest 403 version from post 3 for your phone and flash it, then boot the phone do a factory reset and your good to go with stock ICS.
The latest India version is XWLPF just download teh CSC under that heading to flash.

Could you please let me know from where I can download below file which was mentioned in your link (flash via ODIN)
Just download the firmware version you want from the second or third posts and extract the .tar or .tar.md5 file in the archive and save it somewhere
Also do I need to take any backup before performing these steps?
The FAQ tells you everything.
Backup your SMS and Call Logs using Ritesh Sahu's amazing apps SMS backup and restore / Call Log backup and Restore. - Remember to email the XML to yourself as well!!
Sync your memo's and contacts with Google.
Since you're not rooted, you cant backup specific apps or anything as such - so you will need to download them again from the Play Store (My Apps -> All Apps)
Backup all your SD card contents just in case as well.
Good luck!

[Q] Several questions on how to flash a Galaxy S3

Hey guys,
I want to install a custom ROM my GS3 but before I just want to ask some questions on how to proceed.
My phone is currently running on the SFR (French provider) firmware BUALF1 and I want to get rid of the software overlay (13 app which I can't uninstall).
So if I understand I have to flash my phone with the stock firmware XXALE9.
Then I have to root my phone (I'll follow this tutorial : http://forum.xda-developers.com/showthread.php?t=1701770).
Finally I can install the custom ROM of my choice.
Is that correct or did I miss something ?
Thanks !
ps: Sorry for my English.
If you like to install stock firmware then there is no need for root.
Download the stock firmware and flash it directly via odin. I'd suggest you to read Intratech thread to know all about flashing..
《tapatalked from galaxy s3》
Ok thanks,
I already read Intratech thread but I just wanted to be sure everything was good since it's my first android mobile phone.
If you just want to remove the bloatware you don't need to root you can just flash the regions firmware.
But most custom ROMS do this anyway so if you are going to root and install a custom ROM their is no point in doing this. (You can anyway it will just be a waste of time) Happy Rooting
Wow ok indeed I was going to waste my time so I'm just going to install a custom ROM.
Thanks !

[Q] Get rid off 3 (three) brand to get jellybean

Hello XDA
I've been doing some research on my problem on dozens og forums, but I still haven't got what I'm looking for.
The problem:
I have a danish 3 (three) branded GT-I9100, which doesn't allow me to get the new android 4.1 update, as they haven't infected the update with their 3 junk yet.
I'm not using any of their applications or shortcuts, and would very much like to get rid of everything that has something to do with 3.
I need to backup the stock firmware in order to keep my warranty if something goes wrong, but I haven't been able to find out how to do it, because my phone has a very strange kernel: 3.0.15-1114882 [email protected] #3
I hope someone can help me. I'm not completely noob, i've been rooting my previously android phones without any problems, but I just can't figure out how to do it with this kernel.
Best regards
Morten

1.just flash the nordic jellybean.
2.you dont really get a "standard backup".what you would do is just reflash the firmware your on now (remove yellow triangle etc if needed) then send your phone for warranty.
3.if your phone ever got totally bricked, it wouldnt matter what rom your on if samsung couldnt boot it either to tell.
4.so get the nordic jb rom from sammobile, flash it with odin, root with philz kernel.read about efs backup and nand backup and spockys thread about simlock...lol

First you need to find out if your phone is network locked. Theres an app for that. (search xda/play store) the same app will be able to unlock it for you too but you will need to root your phone.. see my signature for your best option as its root with stock recovery. Your next step go to sammobile.com and find and download your current firmware from there. Then find a jelly bean rom I'm using nordic but search and see what sounds best to you... There are also custom roms you may wish to choose (wannam, jellybam, there are many) find one for you with the search box or browse the forum for them. there are custom kernels as well (jeboo, philz, there are many) find one for you as above or use what your rom choice is packed with.
I cant recommend enough using mobile odin (Play store) will cost you a couple of your currency but its worth every penny.
LASTLY AND VERY MUCH MOST IMPORTANTLY DO NOT FLASH ANYTHING UNLESS YOU ARE 10000000% HAPPY TO DO IT ONE SINGLE MISTAKE AND YOU'LL BE BACK HERE ASKING FOR HELP TO UNBRICK IT.

But how will I find the firmware I'm currently on? My warranty is spoiled if the phone isn't carrier branded,
as I have to hand it to my local 3 store to get them to send it to repair.
Perhaps my question should've been more like this:
How can I backup my branded firmware on my galaxy s2 from 3 (three)
Perhaps I'm a bit noob afterall, as I haven't seen that answer in your post or the others posts.

You havent seen it because it doesnt exist.I dont know how much of a noob you are, but you go to sammobile and get the stock firmware you are on now, and flash that if you are sending your phone back for warranty.
Eg.Im using spanish jb rooted because UK jb rom not out yet.My original software was I9100XWLPT (which is UK unbranded 4.0.4).
So if Im sending my phone back, I just flash the LPT rom from Sammobile; and check no traces of root are on my phone.
So, what you think a backup is/means, is the same result as just flashing the stock rom your on now.
You can check or wait to see if someone can confirm what level of, or if kies can make a backup of your stock rom, as I dont use kies or havent seen anyone using it.They just use odin.

[Q] Need help with flashing the right rom on my device

Good day everyone
I have decided to root my S3 and flash a custom rom of android 4.4.2 on it. Now, i've flashed roms before but what i dont remember and need help with is the difference between the roms and which one is the right one for my device and the carrier i'm with.
I got my S3 from Vodafone Australia. If i remember correctly flashing a rom designed for different radio kernels (i think thats what it was) will brick the phone. is this right? if so could someone please tell me how to find the right rom?
I tried to search and find my answer in forums but couldn't find anything, so any help would be highly appreciated!

you can brick your device only when you flash a rom which is not made for your device...
first confirm that your device is gt i9300
then you can try out any rom from here
http://forum.xda-developers.com/galaxy-s3/development
just find the rom that suit you and read the instructions before installing anything..
for ex for 4.4.2 roms you have to update your recovery to the latest cwm or twrp..
When you flash do not allow the rom to update the radio, otherwise you will lose network connection. Search and read in general forum for Australian S3 discussion.
