can some one plz help me with it.....
thank you
the easiest way ( in my opinion ) is to find your baseband version and down load the corresponding cf root file on itratechs thread and flash it in the PDA section in odin

i am a complete newbie with android so flashing and all is not for me i just need root on my device so that i can install few of the application
As Wezza said, CFRoot is the easiest & most hassle-free root method for SGS2. Takes all of 2 minutes, very remote chance of stuffing your phone up so long as you follow the instructions. By your own admission, you're a 'complete newbie with Android', and IMHO, using a method other than CFRoot to root your phone is just making life unnecessarily complicated for yourself.
Just my (and obviously Wezza's) opinion tho.

Hi all just taken delivery of my brand new samsung galaxy s2 and am working on rooting it,
So far ive flashed the insecure kernel and when it comes to rooting the phone using superoneclick it comes up with the failed message which im not understanding why? Any help would be great thanks
You are probably using the extinct method if you read post one .
Root + CWM .

SuperOneClick is indeed tricky on SGS2. Try using SOC version 1.5.5 or so and also downgrading .NET framework from version 4 to the 3. If even doing this SOC get stuck in "waiting for device", try unplugging and plugging again the phone. Try ten times, in the last it will work I did it in the past, and by my own experience I can say that SOC+insecure kernel eventually works, but you need a lot of patience and persistence.
That said, the best way to get root is flashing a CF-Root kernel. In addition to root, you get ClockWorkMod (CWM) which is a must-have tool. Just flash the CF-Root Kernel and everything is done without hassle. This is what I recommend and what I use. However, if you prefer to use an original kernel (honestly, I don't see any advantages in using an original kernel instead of the CF-Root) you can try the first alternative.

Exactly!!!
im using 1.5.5 but im not sure how to downgrade .net ? and also ive already installed an insecure kernel so i cant see what my old standard kernel used to be to try the cf-root?
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Have a look at the xda bookmarks in my sig and get a recent stock firmware that also has a corresponding root firmware. Follow the instructions to flash them both and you should be fine.
It's actually very straightforward if you read and follow the instructions - it just seems daunting at first. Good luck mate.

It is simple, just completely uninstall the .NET framework 4 and install the .NET framework 3. (google for it and get it straight from Micro$oft website).
Regarding the CF-Root, chose the one that matches with your firmware (eg. my build number, baseband and kernel versions are all KH3, therefore CF-Root KH3) Go for your build number suffix and you should be fine. There is no much difference between the kernels anyway (according to Chainfire's post where the kernels are available for download). Anyway, after rooting, which kernel were you planning to flash? Get the CF-Root counterpart of the same number.
Read Chainfire's first post on his thread, it is plenty of information of the kind.
I am new to the android .and bought my first galaxy s2. I will follow the s2 one click root to root my phone. I need to know if I need the same kernal as my device? My original kernal is JPKG5. do I need jpkg5 insecure kernal and then a jpkg5 secure kernal to root my phone? Or can I change my kernal to some other kernal of my choice?
my galaxy s2 gets pretty hot if I play intense games like asphalt or star legends, it even gets hot if I use mobile internet like EDGE (i guess its 2g internet nott sure) and browse the internet. The battery life sucks. I keep wifi, gps off and it last like 7 hours if I use mobile internet. Heard a different kernal might help.
One last question, what is the purpose of titanium backup? Do I get to restore my phones original self back again easily? Like will it unroot itself and return to the original gingerbread rom if I decide to change to cynogenmod? If titanium backup does not do that, then how can I unroot my phone and then get back to my original gingerbread rom?
Thanks alot for your help...

Welcome to Android I am not sure about the kernel. The purpose of TB is that you can backup all your apps and data and if you flash a new custom rom you can use TB to restore all the apps and data. Its a very powerful application. You can always flash the original stock rom downloaded from Intratechs thread http://forum.xda-developers.com/showthread.php?t=1075278. Then you will have an unrooted phone. Beware of the custom counter!!

If you are international S2 (i9100) user use CF-Root instead SOC:
http://forum.xda-developers.com/showthread.php?t=1103399
Dont use CF-Root or SOC if you are AT&T user, there is specific threads on how to root AT&T devices.
CF-Root is 1 step only, this means for a non experienced user like you (as it's your first android device) less chance to screw up something.
Follow carefully the instructions.
Be sure Kies installed but NOT running (kill kies process) because kies block odin = semi bricked phone.
Takes about 30 seconds
If you need more info feel free to ask here or pm me

im a bit confused, all those stock kernals in that link u gave are kernels and rom? Like if I have cynogenmod rom installed in my fone and then flash my phone again using one of those stock kernels/roms, I would be flashing back from cynogenmod to gingerbread 2.3.3 (JPKG5)?
Also what is the custom counter?

sorry for the multi reply post, dont know how to quote 2 messages in one reply...
Cf-root seems like it will limit me to only one kernel, is it a fact? Is it possible for a gs2 user to use any kernel he desires? because I would like to use a better kernel than jpkg5 but stick to the original gingerbread rom 2.3.3. Then mod it to stop loading the so called bloat somehow using an app. Plus I found cf-root to be a little confusing, can u help me understand this? Cf-root will use the kernel inside the phone and leave it intact plus give me root? Or will cf-root change my kernel permanently?
Thanks for all the trouble everyone, if its ok ill ask more questions if I get stuck, but will try my best to figure it out myself first...thanks again...

If you flash one of those ROMs you will flash from cyanogen to your original. The custom counter counts how many times you flash a custom rom / kernel - it can be a problem if you have to send your phone in for repair. Read more about it.

cf-root is an original kernel with root+cwm inserted. No it dosnt lock you to a single kernel, its just the most easy way to root your phone while keeping your stock rom. When you are rooted you then can flash any kernel or custom rom you want.
You only need to pickup the same (ex: kh3, ki4, kf1 etc..) for the root process, this to have full compatibility during root with the stock rom on your phone, but after successfull root you can flash any kernel/rom for the s2

Isn't there any update.zip available that can be flashed via recovery ??
Or any PC software such as SuperOneClick ??
I9100G root kernels here, which you can flash by following the guide here. SuperOneClick, don't know a lot about it as I've never used it, search on here for the thread.
No, there is nothing you can flash from standard Android recovery to root your phone.

Hi everyone, i've acquire recently a Samsung Galaxy S2.
I came from LF P970.
I would like to know, the best and safest way to ROOT my S2, and Tools and procedures needed to flash new rom.
And yes i've used search and also the INDEX of guides and tutorials, but there are too many for the same thing, so i dont know which one i should use.

Flash a kernel through Odin to root it. Flash a rom through CWM. All of the details are written down in the guides.

First learn how to flash using odin. There are so many guides on xda and other forums. make sure you install samsung kies and have proper drivers for your phone. Then flash siyah kernel v5.0.1 using odin..Then you will easily get root and CWM recovery
