Help rooting Galaxy S2 Vodafone ICS - Galaxy S II Q&A, Help & Troubleshooting

I understand that mods hate these sorts of questions,
But I can say that I have tried 2 different kernals, both didn't work and I was forced to Re-flash my stock ROM back.
I have searched for hours, none of which were similar enough to my situation to be helpful.
My aim is to root, and just root, my Galaxy S2 I9100T running ICS 4.0.3 on Vodafone Australia.
The kernal version is 3.0.15-I9100TDULPB-CL710191 Please keep in mind that my phone it the 'T' model i9100.
I have tried 2 kernals from Chainfire > http://forum.xda-developers.com/showthread.php?t=1103399
They were called
CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5 and
CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER
Both of these made my phone unable to boot past the Samsung Galaxy SII page.
I came to the conclusion that perhaps the CF-root method was not intended for the i9100T model?
I have heard good reviews about the Siyah kernel? Although I have no idea which kernal to flash.
If any one has a recommendation on a modded kernel, please give me the actual link to the download as it will save me a lot of time
Any help is appreciated

Search/ look for 'Root SII without flashing an insecure kernel' under Original Development section.
That method should work for you since you are on ICS.

So what I want is some help i need to correct everything step by step.
I want to root my Galaxy s2 19100 and install an custom ROM i heard that custom ROMS can handle better with the battery this is true right? And what about guarantee i heard you can unroot if you note all your settings.
please help me here are my phone settings:
Phone: Galaxy s2 GT-19100

buildnumber: GINGERBREAD.XWKK2
thank you, and sorry for my bad English

No odin it is a flash tool to flash entire rom or kernel.
Kernel are normally rooted so you can flash a tar file in pda and obtain root and cmw to flash custom rom.
To flash you have to put phone in download mode.
Custom rom have different graphics and some feature but battery life is same.
I suggest you cf root kernel to root and gain cmw.
Also to know your firmware version dial *#1234* and check pda

Please read the Quick Root Guide in Intratech's first post of this thread => http://forum.xda-developers.com/showthread.php?t=1075278
He describes two rooting method, but as you are running a relatively new ROM, the zergRush exploit method won't work for your phone. (The other rooting method will work fine.)
The easiest rooting method is to flash a rooted kernel, such as CF-Root.
Here is Chainfire's thread => http://forum.xda-developers.com/showthread.php?t=1103399&highlight=CF+Root
Stick to his description.
There are a lot of other "good" kernels which will root your phone, increase performance and extend battery life (e.g. SpeedMod, Siyah, NEAK and RedPill).
You will have to search a little bit and then make your own decision.
P.S.: After flashing an insecure/custom kernel, you will get a yellow triangle at boot and the binary counter will be increased.
That's why Intratech and Chainfire also describe how to get rid of the yellow triangle. Or you buy a USB Jig to remove the yellow triangle and reset the counter.

I9100G rooting "ITS G" and updating kernels

Hi friends
U may be knowing that there is other method for rooting i9100g instead of using ODIN.
Its DOOMLORD'S rooting method.(SMALL ALTERATION IN NEEDED IN ROOTING TOOLKIT BEFORE ROOTING) http://forum.lowyat.net/topic/2068824
Advantages:
-NO yellow triangle at startup.
-NO increase in binary count.
-Easiest way.
-I think u can unroot also by UNrooting toolkit( havent tried). http://www.darkyrom.com/community/index.php?threads/root-guide-zergrush-method.7327/
-Root without flashing any customed kernel if u want to. (U can flash other custom kernels with the help of other easiest kernel flasher tool called- "initial CF root flasher" - ( http://www.wuploadsearch.com/downlo...f_root_flasher.rar-wupload-download-link.html ). Even then no yellow triangle and no increase in binary count.
I recommend to flash with this method. i have tried it on XWKJ2 firmware 2.3.6 (GTI9100G).
I HAve tried it on XWLA1, It does not worked for me.
To flash any kernel with "initial CF root flashing kit", u hav to extract "xyz.tar" kernel file and look for "zImage" file and put it in Zimage folder. AS ur already rooted so click "already-rooted.bat" and follow the on screen instructons carefully
You will find detailed method on various other forums (http://forum.lowyat.net/topic/2068824 ). I will provide the softwares and rooting method later on or u can google around and u will find method on other forums and rooting kit along with it.
ITS THE BEST ONE
Till now the best custom kernel is SUPERATMOS 3.0 for i9100g (XWLA1 based)- works on XWKJ2 also.
After lot of CF-Benchmarkings and at any governor ur CPU speed comes out to be EXACT "1200mhz". As previously said that i9100g is capped at 1008mhz.
And in performance governor mode, ur benchmark points shoot beyond the Galaxy SII model.

Was there a question in there? The [Q] in your subject heading indicates you have a question, but I didn't see one in all that rambling. (which, incidentally, regurgitates a bunch of information that has already been posted more times than I can count)
There's already a sticky for this info.

Sorry wrongly clicked question option.
I m just mentioning it bcoz lot of people use odin method and they land up with yellow triangle and usb jig doesn't work on new firmwares and binary count doesn't got reset with stock kernel with odin method. Very often so many people doesn't mention this method and we hav to search a lot where rooting and flashing kernel explained together without having trouble with yellow triangle and binary count.
Thnks

Lastly I have applied most of the mods available till now on stocked i9100g except ntfs3g. I just want to share them.
*sigh*
But again, there are stickies for this info. If everybody posts this stuff (which, unfortunately, lots of people do already) it just saturates the forum, actually ending up making it HARDER for people to find stuff.

What do you want me to do?

Whatev dude. I don't hold any power here anyways. Just giving my personal opinion.
I'm using an I9100g with build DZKL3. I haven't come across any method to safely root my phone. Can anyone verify for sure a method that worked? DZKL3 was released in Dec 2011. (I'm Malaysian). My phone specs below:
Samsung Galaxy S2 I9100G

You can try the above given method. It should work.
THIS method does not work on "XWLA1"

[Q] How to get CWM when using DoomLords easy root (S2)? Not sure which Kernel/method

Hi everyone,
So I just did some research about rooting and custom firmwares and Android in general the past few hours and I finally rooted my Galaxy S2 I9100 with T-Mobile Branding (running Android 2.3.5) using DoomLords root (zergrush exploit): forum.xda-developers.com/showthread.php?t=1321582
Then I wanted to make a full backup of my firmware because I wanted to try out a custom firmware. Of course I did research and I found out that there is clockworkmod which allows you to do backups. Now I don't have that.
I found a thread on another forum which explains a method where you use Chainfire's method to flash a Kernel (using the inital CF Root flasher) as described here: http://forum.xda-developers.com/showthread.php?t=1331784 which is actually for the Galaxy Nexus. Will this also work with the S2?
I've also checked this thread which contains several kernels with CWM: http://forum.xda-developers.com/showthread.php?t=1103399
I got Android 2.3.5 and Kernel ending on KK1 (this Kernel isn't listed there)
Which method should I use? Which kernel should I use of those listed in the above thread? What's the difference between them?
I would really appreciate it if someone would help me out because I am afraid of bricking my phone.
Also this is a wonderful forum and I will try my best to contribute and help people out using the little knowledge I got
Greetings

[Q] Rooting Vodafone SII GT-I9100

I have a Samsung Galaxy S2 GT-I9100 from vodafone. Here are the specs:
Android ver:4.0.3
Baseband:I9100BULP6
Kernel:3.0.15-I9100BULPC-CL332484 [email protected] #3
Build nr:IML74K.BULPC
CSC:I9100VODLP8
Now running on AT&T
I want to root this phone while maintaining the stock firmware or something better. Could some help me out I can't seem to find the right kernel to use. I appreciate it (p.s I did like to unroot at a later stage).
thanx
Since you're on ICS, just use this. No kernel flashing required.
There's a pretty good guide right here:
Your kernel: 3.0.15-I9100BULPC
Look for the LPC zip file in that thread, that is the kernel you need, be sure to read the guide well.
Good luck.

Thank you for the link. I tried it out and it worked out well for me.
Hi,
I have the exact same phone as the OP:
PDA: i9100BULPC
Phone: i9100BULP6
CSC: i9100VODLP8
I've been trying to root my phone to install a custom ROM on my phone for the last few hours but I keep hitting hitches.
I've tried using the customer kernel posted by nawrejin on this thread, but when I boot up my wifi won't work (stuck on authenticating/obtaining IP); that aside I also have a problem with CWM ('cwm manager needs superuser access')?
If I flash the stock kernel for my build then the wifi problem resolves itself, but returns to being unrooted. I don't have a mini SD card so can't use the solution proposed by ctomgee (rooting without kernel flashing).
Can anyone propose a workaround or solution? I've been trying all night now with no success. And I am a newbie noob noob .
Thanks for any input,
Will
Buy an sd card for a couple bucks.
Try to get the sd card. I I hae found this method very effective. When done you could download neat rom lite by Sale and watch your phone fly.

[Q] Help with insecure & stock kernels..I9100T!

Hi,
First time rooting my SG S2 GT-i9100T and I bricked my mobile last night and spent the last 24hrs searching the web for a solution. I finally used CheckFusDownloader_v2.1 as mentioned in one of the forums and was able to down the firmware and unbricked it by flashing it through odin.
I have little to zip experience with rooting and I think I flashed the wrong CF root (used CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER.zip ***). I ended up with the yellow triangle and then nothing...black screen. I rebooted several times and no result...tried recovery reset...nothing. Ordered a USB jig online today and soon after found the Checkfusdownloader and downed the firmware.
I can't seem to find the right CF-Root or the right insecure/original kernel to be able to root my SG S2. The youtube vids and other sites seem to require an insure and original kernel....
1) Is there any other (simple) way to root the SGS2? (tried superoneclick...w/o success)
2) Can anyone help me find the insecure and original kernel that I need?
3) Anyone know if the firmware I downed using checkfusdownloader or from samfirmware is the stock kernel? (I9100TDULPB_I9100THUTLP8_I9100TDULP4_HOME.tar.md5)
My Samsung Galaxy S2 GT-I9100T info:
android: 4.0.3
kernel ver: ...I9100TDULPB
baseband: I9100TDULP4
I'd appreciate any help!
Cheers,
