Hello S2 community,
I've got S2 yesterday, and since then I'm trying to find a way to root it. And I need help.
I found dozens of tutorials, most of them are old, and I am not sure which one would work for me.
I know there's a lot threads like this, but well, I just want to be sure, 'cause I don't want to end up with hard bricked phone.
So, here's some info about my phone :
Model number : GT-I9100
Android version : 4.0.3 (tried to update, it says there's no new updates)
Baseband version : I9100ZSLPE
Kernel version : 3.0.15-I9100ZSLPE-CL232300
Build Number : IML74K.ZSLPE
I just want to have custom recovery(cwm), so I can flash ROMs and kernels.
I had HTC WIldfire S before, and I did root it, but it was an easy procedure, using zergrush exploit as far as I remember, since it was back in 2011.
By the way, is S2 S-OFF by default ? 'cause we had to unlock bootloader in order to root WFS.Or to be S-OFF.
Does S2 have unlocked bootloader by default ?
Thanks in advance!
Darko.
I am told that Samsung phones are some of the easiest to root....Sammy phones don't have locked bootloaders or S-Off (not sure what S-Off is, but as my upgrade will be an M8 I'm going to have to find out)....
With Samsung, the order is.....
1) root
2) flash CWM
3 flash custom ROMs.....
.....or.....
1) root and flash a kernel with CWM baked in via Odin (in one go).
2) flash custom ROMs.
There are plenty of guides stickeyed at the top of general that will point you in the right direction....just have a look.

Alright, done.
I've just followed CF-ROOT tutorial.This is the file I used -> CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5.zip
It's for ZSLPE version too.Did it in 2 mins though, it's quite easy.

Sorry, this may have been asked loads but I've got to ask.
This is my second android device, my first being a HTC Desire which was rooted and I could quite happily flash any ROM that I lay my eyes upon. Rooted fine using unRevoked method etc and the goldcard antics. - It scared me to do but when I had it done then was comfortable flashing new roms all the time. I had CWM 2.5(I think) as my recovery and wiped data/cache/dalvik with ease.
Is the Atrix on par with that? I mean after I have rooted and unlocked my bootloader, I am wanting to just have the stock gingerbread rom and then the fixes that I'd need like the ram fix etc.
But really, just how hard(& scary) is it rooting, unlocking and flashing GB rom?
Sorry if my post is very ....erm...... noobie if you like..
I had a nexus one.. rooted, unlocked, various roms.. great phone.
my atrix is hard bricked beside me :-/, and im back on the N1..
lots of tutorials lots of 'if your this version', 'if you came from here, but are here now, dont' go here', etc... seems more 'gotchas' and accidents can be made with the atrix than my nexus one..
Since it's been out a while, it's pretty easy. There's step by step guides to unlock and flash any rom you like. Personally, I'm on KPs 2.3.4 Beta 4.5 rom, and it works great. Browse around in the Development section and you'll see a guide for ANYTHING you want to flash. It takes little to no knowledge to do. Not scary.
So from what I've found...
I root using this:

I really don't know where I should start, currently my specs are:
System Version: Version.4.4.20.MB860.Orange.en.GB
Firmware Version: 2.2.2
Baseband Version: N_01.95.00R
Webtop Version: OSHWT_U1_6.61.6

Build Number: OLYEM_U4_4.2.0
I am right there with you I bricked my Atrix already and don't want to do it again. There is to many ways to root and unsafe ways to root someone needs to compile a guide on how to root install CWM and then install Roms safely.
I agree, Theres a noobs guide for AT&T users, we need an International one now....hint hint anyone..?
I am a noob to Android but I followed the steps in this thread and I unlocked my BL and rooted my phone with ease. I did this after having the Att GB ota.

Hello everyone, I'm new to this forum, and I would post this question in the appropriate thread, but alas, as I have less than 10 posts, I am not allowed to post in the developer forum.
So anyways, I will be receiving my Samsung Galaxy S2 in a couple of days, and plan on unlocking it (for free), which can only be done via a root app, that obviously requires the phone to be rooted.
After extensively reading several guides on rooting the GS2, it seems like a fairly straightforward process, but I do have a question about flashing the insecure kernel:
- Do you have to use a specific insecure kernel version for your device? I have seen a few guides that say you must use the specific kernel for the firmware you are running, but then other guides say that you can download the "XWKDD Insecure Kernel" to use.
If it must be a specific kernel, how does one go about finding out which to use?
Also, I am planning on flashing back the stock kernel and unrooting once I have the phone unlocked, so since it is SIM-Unlocked, it will stay unlocked forever, no matter what I do with the firmware, correct?
Thank you!
If you search for a rooting kernal according to your firmware then you cant go wrong.you will need the proper kernal to root it.one root kernal doesnt root eveything so seach according to your firmware.secondly the only true way to have a phone unlocked forever is via emei. Number.i had an sgs unlocked through a program similar to what your talkin about and it worked fine but when i reflashed the firmware to 2.3.4 it relocked.but if your not gonna play around with reflashing then shouldnt be a problem.the most common root kernal seems to be chainfire and works perfectly.
Thank you so much for answering my question.
So, when you say that the only way to have your phone unlocked forever is via EMEI, are you referring to the unlock code? I will be using this program: https://market.android.com/details?id=eu.chainfire.sgs2simunlockcode
By using this program, it will find the unlock code, and then I can use that to unlock the device, and I believe it's via EMEI, so reflashing the kernel should be no problem, correct?
The method I have chosen for rooting and unrooting (I'll unroot and reflash a stock kernel after I have the unlock) is this: http://forum.xda-developers.com/showthread.php?t=1125414
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
Build: GINGERBREAD.ZSKG2
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
Build Number: GINGERBREAD.ZSKF4
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 .

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?
my new sgs2 is coming in a few days. what should I do before rooting?
should i update so it has a newer kernel/firmware?
I'm trying to follow Chainfire root: http://forum.xda-developers.com/showthread.php?t=1103399 and it seems that the old radios are not supported.
You should research. If you found a thread with instructions on what to do and you are not sure, ask there.
You should however NOT ask for hand-outs.
Basically all you need to know is CF-Root. Or you could try one-click-root

I did do research. My concern is that only the older versions of CF-Root work with older kernels, like KE, etc. so if I get an old phone, I'm wondering if I should then update to the latest gingerbread version before using CF-Root so I can apply like 5.0?
Hello,
first of all if your phone isn't a new one you will see if its already rooted or not !
if its not, then you have to root it and the only way from stock rom is to flash new kernel version with CF-Root, and CWM is great too for not being often on odin/download mode if you don't want to...
anyway have nice time with your phone its a great one and hard to brick as long as you don't touch to bootloader file..
The CF-root thread has a big list of ROM versions. Just pick the kernel that matches the ROM version of your new phone and you should be all set in rooting the phone.
Here you go.
http://forum.xda-developers.com/showthread.php?t=1103399
I'd strongly suggest you use the phone without doing anything to it (rooting, flashing kernels etc.). Most people find the phone just right the way it comes out of the box.
You should only consider rooting or flashing something if you have a specific need for it.
