I upgraded my firmware today on my UK T-Mobile SGS2 today, but lost the root I had in the process. I was previously having a really annoying 'lag' that would make the whole phone jerky and unresponsive and that seems to have cleared up after this upgrade. I'm really keen to do the rooting properly this time... as I'm guessing it was a problem of incompatability that cuased the jerkyness problems I was experiencing before.
From the Chainfire rooting thread I see that there isn't a rooted kernel that is for KG2 and Android 2.3.3
CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4.zip - Is for 2.3.4
These files aren't labeled as being 2.3.3 or 2.3.4 - does anoyone know:
CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
CF-Root-SGS2_JP_XSG_KG2-v4.1-CWM4.zip
If you were in my position, what would you root with?
My current phone details are:
Modellnummer:
GT-I9100
Android-Version:
2.3.3
Basisbandversion:
I9100BOKG1
Kernel-Version:
2.6.35.7-I9100BOKG2-CL255512

If you are going to root then flash a custom Rom, then I wouldn't worry as the Rom will be based on 2.3.4 probably.
If you want to stay stock, then you could follow my route, CF-Root then flash VillainRom which is based on 2.3.4 and as close to stock as possible with a few tweaks to improve things such as battery life.
Hope this helps
Ideally I'l like to be able to get future official updates through Keis - and I would lose that if I switched to Villain rom right?
I also wondering if I'm going to flash a custom ROM, might I as well flash a more recent Samsung one like KH3? Looking at Villainrom it says there are problems with the stock browser and stock SMS.
Piecing together info from other threads I saw that someone said that you can flash a rooted kernel and then flash back your original unrooted kernel and it will stay rooted. Is this true? If so, perhaps I could flash a rooted kernel (either a 2.3.4 or a 2.3.3 for KG1 or KG3 (close to my rom), and then flash back my current KG2. Thing is, how do I get my current KG2 kernel off the device before I overwrite it with a rooted variant.
Sorry if my questions are a bit basic or confused. I'm still trying to get to grips with all this. Thanks for the patience!
1. Yes you will lose updates through Keis but the custom Roms are based on the most up to date anyway.
2. Don't think you can restore your kernel and keep root afaik busybox etc are baked into the kernel
3. Yes there is a lag problem, it is to do with odexing/deodexing (don't ask me) but there is a flashable fix if you search the thread. Villain Tweaks app should help with the SMS I think.
4. Find your firmware/kernel on Intratechs thread and download it and keep it safe. When you root you will replace the current kernel. If you need to go back then you can flash the original through odin.
Well, since it seems going with a full flash is the only way of rooting with my current officical setup, I'm gonna try KH3 and see how it goes. I'm quite relctant to get into custom romming because I don't normally have the time to deal with the inevitable problems (so I hear), but I do need to be rooted. Wish me luck! and thanks for your help.

Okay guys, First off I apologize if my post is too noobish. Yes I am a noob at all this.
I rooted my phone using steps mentioned here - http://samsunggalaxys2review.org/forum/showthread.php?tid=43
I bought my phone in india with the KE8 update, and now the About Phone section shows the following:
Android Version - 2.3.3
Bsaeband Version - I9100DDKE2

I read about a post for rooting the galaxy S2 here - http://forum.xda-developers.com/showthread.php?t=1101671
and am a little bit confused. Firstly did I do the rooting with a piece of old software or something? Do I need to do the rooting again or flash my phone with some other latest software ?
Can someone please spoon feed me some info about:
1. Whether I need to infact update my software and flash my phone again
2. If so how?
Thanks a lot guys, and again sorry for being too noobish :S

Well I have rooted mine yesterday after a 3 hours effort. I think there should be a thread for Noobs like OP and me which will elaborate the Steps & Methods, the Application needed etc. in a Simple way with good demonstration. Not everybody had Android before, so for the new comers this is hard, very hard to understand all these. Like I am now having difficulties with ADB, I don't even know where to install it and from where, how to use it? The devs are very easy with these stuffs and they just mention the software name, but we, newcomers to Android are getting puzzled. It's a like a 5 year old baby has to face class X straightaway.

This is the stock kernel which came from the Samsung factory. The phone is NOT rooted if you did not root it. You can do rooting with an insecure kernel and then revert back to the stock kernel, keeping the root intact.
So last night I rooted my Samsung Galaxy S2 and I’ve got a few questions regarding various things that I havn’t been able to find through searching around on the forums. If the answers are around the forums and I have missed them I apologize and hopefully you can direct me there.
1. Since I used chainfires rooting method. I’ve used Nitrality’s app to ‘backup’ my /efs and something else it backup up. Here I’m wondering if I use a custom rom such as “Lite'ning Rom v6.1 XXKH3” will the things I backed up with Nitrality app restore my original ROM and Kernel incase something hardware wise fails and I need to send it back in to claim on my warranty.
2. The second question im asking is regarding various Custom roms, if I choose to flash ;Lite’ning rom, will I be able to since it states it’s;
based on I9100XXKH3 firmware
baseband I9100XXKH3
The baseband I’m using is XWKE7, will I be able to use this rom?
3. since the version of android I have is 2.3.3 and majority of the Roms need 2.3.4 will it work correctly? If not and I have to legitly update to 2.3.4 will it successfully update since i've rooted my phone?
Hopefully you guys can help answer my questions. Thanks.
bump because I really need help :[
- Litening ROM is based on KH3 ROM, that doesn't mean you need to have a Stock KH3 ROM. So yes, you can install it.
- As I said it doesn't matter what ROM you currently have to flash a 2.3.4 ROM.
- Don't know about the Back up issue, sorry.

thankyou so much for your help
before I flash it will I need to upgrade my 2.3.3 to 2.3.4 though?

First off, I'm completely new to this and wish to root my new sgs2, and I've done some reading on the forum about this but got some questions (or want to confirm what I think I know) before I actually go ahead with the process. I apologize if it's something others have already asked, but I would really hate for anything to happen to what has become my new baby...
I mainly just want root access on my phone as I've come across several apps and what not that required root access.
My phone's status right now:
Android version: 2.3.3
Baseband: I9100XXKG1
Kernel Version: 2.6.35.7-I9100ZSKG2-CL361136 [email protected] #6

I found (http://forum.xda-developers.com/showthread.php?t=1103399) about CF-Root. It seems like a lot of people recommend this method to root, so I thought I may try it out. Before I do though, I wanted to know:
- Just rooting my phone will not prevent me from receiving any new updates to my phone via Kies, right? (E.g. a new firmware or version comes out in the future...)
- What do I need to do if I wish to unroot in the future?
- For this method, this should be the one I should download and use right? (it's the closest one I found matching my current kernel): CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
Again, sorry for asking what may be pretty simple questions, but I really appreciate everyone's help!
Hi,
You can follow this (http://knowmydroid.com/guide/root-samsung-galaxy-s-2) step by step guide to root your SGS2.
1) Yes, rooting your phone means you cannot use KIES anymore. Its highly not recommended
2) Download any official firmware from SamFirmware.com and flash via ODIN
3) You can flash the KH3 version of CF-Root as well.

Hello,
you will still receive updates via KIES.
Unroot is possible with SuperOneclick. I have not tried so far. Every new firmware overwrites root. So if you root with ODIN and flash the rooted Firmware to the original one, KIES will allow to upgrade.
You could also use ODIA's insecure original kernels and use the ones provided from INTRATECH to have the original back on.
Never tried CF myself.
This phone is practically impossible not to root! Read everything thoroughly and take the dive, see you on the other side

Thanks~
Thanks for all the help! I did take the plunge ... and have no regrets!
I used CF's way, and have flashed back to my original stock kernel afterwards (courtesy of INTRATECH). Everything seems to be happy so far.
And now.. time to have some real fun with the phone
Thanks again everyone!
I also recently rooted with the CF-Root method. Congrats from a fellow HK/Taiwan phone user.
Check out this thread if you are interested in an XXKH3 rom with Chinese input: http://www.mobile01.com/topicdetail.php?f=568&t=2188818&last=30718996 (Note: I have not tried these myself.)
Hey all,
I'm a beginner in this rooting society, moving over from jailbreak development on iOS. I am wondering how I would be able to root a Galaxy S2 with model/kernel number ZSKF4 running 2.3.3.
Not sure if this is the proper place to put this, but I've searched everywhere and no place is providing an insecure/original rom for rooting with this kernel number on the file name.
Can somebody help me?
Many thanks,
Nicholas
UPDATE: Anyone know how to root ZSKI2 running on 2.3.5?
Root + CWM .

Thank for your reply.
Many guides like the one you gave me, requires kernel matching first, but really, I'm entirely lost in this matching process. Can you give me some heads up on what to choose using my specs I list below?
My Galaxy S II:
Model Number: GT-I9100
Android Version: 2.3.3
Baseband Version: I9100XXKE4
Kernel Version: 2.6.35.7-I9100ZSKF4-CL280225

If you can help me, I will be very grateful.
Thanks a lot!

Instructions in the post are .
Don't worry too much, just find the matching download and use it. What if there is no matching download ? You can ask me to make one, but I can tell you right now, I very very rarely make CF-Root's for kernels on request, unless it is the very latest kernel that has been released by Samsung. In the latter case, be sure to let me know. If there's no match and I'm not making one, try finding the closest match. You should treat "KG1" as a number, but instead of 1-9, we have 1-9, A-Z (where A would be 10, and Z would be 35). "KG2" is really close to "KG1", "KF1" is not close to "KG1" at all.
You want then a KF4 kernel from post 5 .
jje
This one from post 4 should do it: CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.zip
You have a HK/Taiwan phone? If you install Kies you should be able to upgrade to the official ZSKG2. Although that is still 2.3.3 so not much difference there.
Yes, I have a HK/Taiwan phone,
Thanks guys,
So if I have ZSKF4 right now, I'll use "CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.zip"?
If I upgraded to the latest ZSKG2, will there be any difference comparing to ZSKF4? because you said its the same 2.3.3.
Okay, well after looking at the instructions, I got a little freaked out of how long it actually is, and was pretty worried if I do this, I would get a triangle at boot because I'm using Custom Kernel? Also I heard that many people don't want to use CF-Root because there's a higher risk of bricking comparing to SuperOneClick that I used to root my Galaxy Tab 7. So, I checked on something else.
http://forum.xda-developers.com/showthread.php?t=1125414
Thats a one click rooting app for the S2, but what is this "Flashing an Insecure Kernel" and how do I get this kernel for either ZSKF4 or ZSKG2? I prefer the most easiest way so that I wouldn't run into a huge risk of bricking this device. Thanks for all the help on CF-Root above, but would you guys happen to know what exactly is going on in this link?
http://forum.xda-developers.com/showthread.php?t=1101671
That contains all the insecure kernels for the S2 one click rooting application. Which one do I choose if I have ZSKF4 or ZSKG2?
Thank you everyone for helping me,
Nicholas
Rooting with CF-Root is very easy, just start up Odin, click the boxes like it says in the instructions, and it's done in less than a minute. You can use the other method, but if I were you I would just go with CF-Root because 1) so many people have done it and 2) at least you know one person (me) who did it on their HK/Taiwan phone and came out fine (and I was a complete root noob at the time).
I think whether you upgrade to ZSKG2 first depends on why you want to root. If you are rooting so that you can install a custom ROM, then no need to upgrade to ZSKG2. Just root your phone and install the new ROM and you're good to go.
But if you want to keep the Samsung firmware and only rooting so that you can run certain apps or do certain mods, then upgrade to ZSKG2 through Kies first, then root. There is nothing really bad about the Samsung firmware. I run Cognition 1.5.1 + SpeedMod, but it's mostly just for the fun of it. I don't do anything on it that I couldn't do with rooted 2.3.3 Samsung firmware.
And yes, you do get the bright yellow triangle at startup. There are ways to remove it, but I haven't tried. I like the triangle, it's like a little badge of honor for power users.
Yeah, I'm only rooting for just certain apps that require root/superuser requirements. Other than that, I won't put a load of mods on.
So, if I go to Kies, upgrade to ZSKG2, then I begin rooting, would I be using:
CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
But the thing that scares me is that it says "ZS_OZS_KG2: Untested", does that mean it would be risky to do it?
Hey just noticed in the General forum that the official ZSKI2 is out - and its version 2.3.5 to boot. Check it out: http://forum.xda-developers.com/showthread.php?t=1281717
Yeah the "untested" means the author did not try it personally (can't really expect him to test every kernel from every region). I used it and it worked fine -- that's all I can really say.
Oh wow, that looks pretty cool....
I'm sure I can update to that, which I will, but, does this mean I have to wait for another rooting procedure?
I have a crazy "OCD" that I have to always stay up to date haha. So yeah, if I do this, logically if the CF-Root is able to root it, I will have to wait for a person to make the ZSKI2 kernel insecure version?
Actually, okay, when I upgrade to ZSKI2 kernel, which "CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip" do I use? I don't see a ZSKI2 kernel anywhere...and I'm assuming I can still use CF Root to root at 2.3.5?
You can use a version that is close -- in this case I think XX_OXA_KI3 is the best match. It will probably work with the ZSKI3 firmware -- but I have not tried. (Sorry I mistyped the name in my earlier post, it is ZSKI3 and not ZSKI2.) If you want to be safe then yes you will need to wait until there is a rooted ZSKI3 kernel that you can use.
If you plan to install a custom ROM, then it does not matter what kernel you use for root, since the custom ROM will generally come with its own rooted kernel and it will replace whatever you had before.
For some reason, Kies isn't letting me update.
It says: "This version of this device cannot be updated"
Do you know why this is happening?
By the way, I noticed when I plug in my phone to Kies, I see under CSC, in brackets are (KOR). What does this mean and does it affect any rooting?
UPDATE: I know what KOR means, it means it's a Korean region based device. Is there any difference to what I may be able to update to in Kies or any rooting differences?
Hello all,
To begin here are the current specs of my At&t Samsung Galaxy S2:
Model Number: SAMSUNG-SGH-I777
Android Version: 2.3.6 (yes, i have done OTA update from 2.3.4)
Baseband Version: I777UCKK6
Kernel version: 2.6.35.7
Build number: GINGERBREAD.UCKK6
So now onto the reason for this post, I have spent several hours...several months uptil now trying to fully understand the rooting process for the At&t Samsung Galaxy S2 and I have a few questions around the entire process that i would like to get some concrete input on.
My objective behind rooting is only to get SuperUser access and be able to remove all of the at&t/samsung apps i dont need or use, and to use apps like titanium backup to backup all my stuff...i dont plan to ever install anything custom on my sgs2 as the stock rom is sufficient enough for what i do on the phone (at the moment).
with that said:
1) is it possible to keep everything stock and just but just enable the SuperUser access, if so, can some1 point me in the direction of what all i need to achieve this?
2) (if #1 is achieved and ) if i just root the phone by keeping everything stock, is there a posibility that my flash counter on sgs2 will get incremented? ( i am aware that there is a method to undo/reset the flash counter back to 0 ("NO"), but i would like to avoid incrementing it to begin with).
thanks for your input!
