Dear all,
I'm sorry in advance if the post exist but I'm completely lost with the process of rooting and install cwm and new roms on my Samsung Galaxy S2 I9100. I searched a lot how to do it and in the safer way as I don't want to brick my phone.
My phone version is:

Android Version : 2.3.3
Baseband Version: I9100JCKE1
Kernel Version: 2.6.37.7-I9100XWKE7-CL215725 [email protected]#2
Build number GINGERBREAD.XWKE7
Please help I would like to root and install Jellybean ROM 4.1.2 or 4.2 either Official or Custom on it. If needed install CWM
Thanks in advance for your help
P.S I think it is the International I9100

Doomlord oneclick is tge safest way.
Framaroot app could also work as it's an exynos exploit.

Ok, as I have got a little bit time to help you saving time, here are my favorite rooting threads:
1. Chainfire's CF-Root thread => http://forum.xda-developers.com/showthread.php?t=1103399&highlight=CF+Root
Please read Chainfire's first two posts carefully before flashing anything.
If you can find the corresponding CF-Root kernel to your ROM (should be "XX_OXA_KG6"), then this is the easiest flashing method and provides the CWM Manager (including ClockWorkMod recovery with additional features for backup, recovery, flashing zip files, flashing kernels, etc.).
2. Intratech's "Quick Root Guide" in his first post of this thread => http://forum.xda-developers.com/showthread.php?t=1075278
This is a little bit more manually but works on every ROM (you only need the stock kernel to get rid of the yellow triangle after flashing).
Thank's for helping.Will try tomorrow.

[Q] Samsung galaxy S II GT-I9100T Stock kernel for Vodafone Australia

Hello everyone, I've just recently switched from iPhone 4S to Android Galaxy S II. My phone info is given below:
Model: GT-I9100T
Android version: 2.3.5
Basband version: I9100TDUKJ1
PDA: I9100TDUKJ1
PHONE: I9100TDUKJ1
CSC: I9100TVAUKJ1
I have already followed the guide http://forum.xda-developers.com/showthread.php?t=1103399 to root my phone. I used http://download.chainfire.eu/50/CF-Root/SGS2/CF-Root-SGS2_XW_LUX_KJ1-v5.0-CWM5.zip and used Odin to flash it. I'm now having the yellow triangle which I want to get rid of. According to the instruction, it says "(4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)" however, the secure kernel link which I found from http://forum.xda-developers.com/showthread.php?t=1101671 does not seem to be listing any KJ1 version. Can anyone please provide me a link for downloading this? Would it be the one here? http://hotfile.com/dl/144715979/1949050/I9100JPKJ2_I9100OJPKJ1_I9100XXKI4_HOME.tar.7z.html
Thanks in advance.
metalmaze,
Your best bet would be to download the stock firmware from Samsung themselves. Unlike many other companies, Samsung has a database where all (or rather most) of their stock firmwares are stored.
Since I'm unable to post outside links on the forum for now, do a Google search for "SamMobile firmware" and click on the first link. You will have to register in order to download any files from SamMobile, but it is quick and free, definitely worth it.
Hope this solves the issue! Best of luck!

Hey omar7os, the link you gave me does not have the KJ1 kernel so far I can see? Also, the rooting part isn't the problem, the flashing of the stock kernel to get rid of the yellow exclamation mark, while retaining CWM v5's features enabled is the problem. I believe this is due to not having the proper stock kernel for the KJ1?

Hey omar,
You're missing my issue here. My issue is not rooting, that's easy. But I'm trying to get rid of the yellow icon by following the instructions which is not working. So I believe I need the stock kernel for KJ1.

[Q] The safest way to root Galaxy SII i9100?

Hi there,
Please could someone post relevant information on how to root the Galaxy SII, I have searched a lot of threads and can't seem to find a reasonably safe solution to my question. People say its not possible to root a Galaxy SII lately due to a hardbrick bug in the chip. Please could someone enlighten me on this topic and tell me if it's safe or unsafe. I will post the details on this thread to the best of my knowledge.
Ok here goes;
Model number: GT-I9100
Android version: 4.0.4 (ICS)
Baseband version: I9100XXLQ6
Kernel version: 3.0.15-I9100XWLPT
Build number: IMM76D.XWLPT
Also, I have installed the eMMC brickbug check app from the play store and here is the result i was given;
Brick Bug ? No. Sane chip (no idea what this means but I'm guessing my chip is safe to just flash any Kernel?)
I am just looking to root for now and possibly flash a custom ROM in the near future but at the moment I am happy with the stock firmware but I just want to be able to use Titanium Backup, Superuser & ROM Manager but i am unable to do so until I have rooted my Galaxy SII.
I'm not new to any of this because I previously had a ZTE Blade which I rooted & flashed custom ROMs myself, this was a walk in the park compared to the Galaxy SII. On threads which I have browsed through, some people state to use Siyah Kernel, would this be safe to flash through Odin? Or maybe I could use CF-root.
thank you for reading my post & I'd be so grateful if someone could provide links and/or instructions. Much appreciated!

http://forum.xda-developers.com/showthread.php?t=1746794, use that, method 1 always works.
oh and if you just wanna be 100% you wont be affected by brickbug, just flash siyah kernel through odin, that will give you root + CWM recovery
In my opinion, you should go for siyah but pick whatever u prefer
Thank you Poroto, I will probably try the method 1 posted by Phil3759. That looks kind of safe but I'll read through that thread you posted first before I decide. I really appreciate your help

No worries, just remember not to wipe anything on stock 4.0.4 kernel under any circumstances.

[Q] Root a I9300 XXEMF1

Hi there,
I have a question that may seem silly since I am using an S2 for almost a full year, so here it goes:
I am now in the possession of a S3 GT-I9300 and I would like to root it. The firmware model can be seen in the attached print-screen.
Q1: Is there a way to root it from SD, without needing to use CF-Root and Odin (I have found this file CF-Auto-Root-m0-m0xx-gti9300.zip but i don't know if it's the right way to proceed as I have rooted directly from stock recovery on my S2)
Q2: I have been reading and there are devices with locked bootloader and others with unlocked bootloaders, and it seems that if you flash one for the other you will probably brick the device. Is there any way to tell what kind of bootloader you have?
Thank you and sorry if my questions seem trivial to you,
Doru

1. There maybe some flash zips that auto-roots your phone without using odin but CF-Auto root is one of the safest way to root.
2. The international model (GT-I9300) is always bootloader unlocked. The root will not damage any part of your bootloader but if you brick your device then i'm 100% sure that you flashed the wrong file. If you want to know what version of bootloader you have then download the app called Android System Info on Google Play.
baseband version or build number is important in this rooting process ? i have gti9300 ,on 4.1.2 and
baseband version - I9300DDEMG2
build number -JZO54K.I9300XXEMG5

It doesn't matter what baseband you have. It has nothing to do with the rooting process.
