hi to everyone, im new her (well been checking for a while since i goy my first epic but i just decided to register) i have a question that i havent been able to find out, i just got a galaxy S2, and i want to root it, first to remove al unwanted apps (belive me in mexico, Telcel charges phones with a lot of useless ****) i already read how to root it, i know about the insecure kernel and all that stuff (i have a little previous experience with Epic 4G) but here is the thing
the version on mi cel is 2.3.4 and kernel UMKG4, from what i'd understand i must install an unsecure kernel (the same as the OEM one but unsecure version) so i can root it and then get CMV, super user, etc
so i havent been able to find this kernel version, what happens if i install another kernel version? and then if i want to flash back to OEM to remove the yellow triangle at boot, will it work with another kernel version even if its not the oem one?
i thank you in advance for clearing this doubts
A different kernel version should not cause any trouble as long it's not an "ancient" one (like KE2 or KE7).
Also see that it's a kernel that comes from/for a ROM with the same Android version - 2.3.4, in your case, so XXKG3 should work fine for you.
For XXKG3 there's root kernels, stock kernel and everything else you need floating around.

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
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

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.

Jiffage ?? Did you make it ??
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 .

Read the post in regard to versions /kernel matching first .

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!
Nicholas
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?
Hi, I have the orange i9100p - and rooted using the rachmat3 method
I could really do with a few pointers- Especially from people with the same phone version and root method
I've flashed ROMs before on other phones (desire, desire HD Touch Diamond) but the whole thing seems bewildering on this phone, I've spent days reading and still dont really know whats going on and whats the best way to proceed
So my phone is as stock, still with the Orange ROM updated to ICS, I assume it has stock kernels, but it is rooted etc
I was hoping to flash another ROM, maybe without the Orange stuff, and perhaps one that can use JKAY or something as everyone seems to think thats great and mine dosent seem to be supported. Also maybe deodexed if thats worth doing. I dont like the stock unlock screen, and also tried the s3 launcher and it didnt work on this current ROM - so I want to switch to something that will allow me to do these things.
The only trouble is I have no idea what do. Nothing ever seems to be the obvious way forward
These are some of the questions I keep coming up against -
Should I be able to do these things on my current ROM -
If I change ROMS will I loose NFC (should I care?)
Do I need to keep the same kernel to avoid brickbug risk, and to keep things simple, and if so how do I do that, they all seem to come with Kernel with Chainfire installed which I dont need right? (delete zimage out of the zip file?)
Should I flash with the temporary CWM, or use odin (I haven't used odin yet - can I use it with only the temporary CWM)
Are there any obvious ROMs that would be easy for me to get the above from
Here are some details -
model - gt i9100p
Android version 4.0.3
Baseband version i9100pbvlp7
kernel version [email protected]#3
build number IML74K.BVLP8
Anyone with this phone model in particular, or if you used Rachmat3's method - I'd love to hear what you've done
Free bump for an interesting title.
I'm in a similar situation to the original poster. Got the I9100P UK Orange phone and wanting to flash new firmware but a bit daunted by the information and options out there. I've flashed the old Samsung i8910 and that was pretty painless. The S2 seems a lot more complicated and with more potential problems!
If you can afford the risk, all you need to do is take the leap of faith. Rom and kernel are mostly "safe" to flash (except stock 4.0.4), if incompatible will result in soft brick the phone, where you only have to get it back to download mode and flash back a working one.
Yes, i think you will lose NFC...
It is daunting but dont just be like most of the noobs on here and proceed without doing any research first.
They dont even have the decency to read about basics like
What is cwm
How do I root
What is Odin

So, I have one galaxy s2 i9100p (O2). I come from a stock gb, rooted and flashed a new custom rom using the recovery mode, full wipe and every other things... I lost the nfc function and never found a method to bring this back but every other things are working fine, very fast and stable on 4.0.3 version with siyah kernel... i think you don't will have problems too but you will lose the nfc. it's your choise BTW, I have the stock ics rom with NFC (o2), I don't know but if you need, send me a PM, just flash the .tar file with odin and everything will work again (NFC), like factory new one (sorry my english :/)

Hi there,
I have the same phone model with the same kernel, radio and stock rom.
Did you manage to upgrade firmware to JB (which kernel and rom did you use) and keep NFC??
hi,
i have a new sg2 i9100 version witch came with 4.04 and no brick bug as reported the emmc.
i am searching for days and i am a bit confused .i am not familiar with that kind of softwares and i would like your help.
the goals: i want to root, and to be able to flash any rom i want.
1)if i understand so far i will need a kernel too?
2)i do not have the knowledge to understand what varius kernels offer and i simply choosed the siyah since it is the most popular(??) the s6 version states "This kernel is only for Samsung JB ROM (No ICS support anymore).
that means that my ics 4.04 will not be accesible and working anymore and i should flash a rom imidiately after the kernel flash?i do not mind to flash rom imediately after siyah kernel since i do not have anything instaled on the phone yet.
is it posible?with odin?1.86 , 3.04?
3)after the siyah kernel flash from the oficial siyah site , do i have root?
4)do i have cwm? if not what do i need to do?
5) is the siyah consider safe kernel?
thanks
i apreciate your help.

Frist root your phone, everything will be explained in the thread. Check FAQ
If you don't know what you are doing, don't flash siyah and stay with the kernel that gets installed when flashing the rom you want.
Flash a custom kernel with Odin. Another Siyah kernel than v6 will do, just check the changelog.
You will have root, CWM and you're able to flash custom roms. You can choose to try other kernels than the one that comes with a rom, but it's not a must.
And the person above is right: If you don't fully understand all this, try to learn a little bit more. It will prevent you from doing something wrong.
Good luck.
