Hello.
================
Gonna start off by saying I loved the noob video when signing up.
I also want to preface by saying I genuinely have looked - all day - and am still very confused.
I've been on iPhone since since the 3g, I loved it, but I wanted a change, and the GS2 gave me reason to change. I was massive into jailbreaking and customising, so naturally I want to tinker with this phone.
The problem is I don't have a clue. I know nothing about android, and I know nothing about rooting ect...
Any of the many guides I've seen all say different things, I can't seem to find one clear cut definitive guide.
================
I don't know what info you need so I'll just list what's in the "About Phone" menu.
Galaxy S2 i9100
Model Number - GT-I9100
Android Version - 2.3.3
Baseband Version - I9100BUKG1
Kernel Version - 2.6.35.7-I9100BUKG2-CL342890 [email protected] #2
Build Number - GINGERBREAD.BUKG2
It was bought in Ireland today on the Vodafone Network.
I know the pros and cons for Rooting - as I said I have been researching as much as I could, but now I just need pointing in the right direction to a guide that will suit my needs exactly.
Also, I have ordered a 16gb sd card for it, so I will have it soon, but I do have a 2gb one if that's any good for now? - Does the sd card retain the root or can all files be deleted off it after?
I thank you in advance for your help.
have a look here, i found it to be the easiest to follow and the kernal works great

Thanks a lot guys. I'm gonna have a good read through all of your suggestions now. I'll let you know how I get on.
Thanks again.
The easiest way to root is just put phone into download mode and flash CF-Root, it will automatically root your phone with busybox and other good stuff. I think you can then flash Stock kernel again if you don' want to use CF Root and the root will still remain intact.
Also, can I use a 2gb card for this then switch to a 16gb without it affecting anything?
Root is not involved with the external sd card so you can swap .
jje
So, If I follow this one [just to root] - does that mean I then can put other stuff on like kernels*? And if I decide I don't like the kernel can it be taken off? - or do I put another on top and it deletes the first?
Basically [as I'm brand new to rooting] what do I do after rooting?
You do nothing after rooting . All it does is open the door .
kernels can be flashed via Odin one will replace the existing kernel . Likewise firmware can be flashed via Odin .Likewise custom roms though they are often via CWM .
Read some posts in the development section is what i would start with stock roms and custom roms .

Thats a root kernel, you flash it, it roots your phone, but apart from that it acts like stock.
You can put other kernel's ontop and they will replace it, you cant remove a kernel.
You will keep root if you change your kernel, but if you change rom you may need to reroot.
Thanks a lot for all your help. I'm rooted now, frozen bloatware and very happy.
Does anyone know if I can get the battery icon in the status bar to show its percentage? I've only seen widgets which I don't want.
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!

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 Guys, I've been searching and searching for several days now, and trawling endless requests and information about what kernels are compatible with what, but [blank look] huh?
Being an HTC user for the last 5 years, this all seems overly confusing, just when I think I have the info I need, I read a contradiction, then the thread dies!
So my question, and I apologise so much if this has been (and I'm sure it has) asked before:
I have a KH2 orange branded SGS2. I've flashed a new kernel (KH3) CFRoot, didn't put the original one back on because I don't want to lose CWM - it was invaluable on the hero, g1 etc.
Android Version: 2.3.3
Baseband: I9100BVKH1
Kernel: 2.6.35.-I9100XXKH3-CL479037 [email protected] #2
Build: GINGERBREAD BVKH2
But I still have the old Orange Firmware / Rom on the phone. I want to try some new unbranded ones, and check out how cyanogen works (and hunt out villainRom! My fave), but worried that if I use a rom with the wrong code (i.e based on XWKL1 or IML74K) I'm going to end up with an expensive (but very pretty) paperweight.
I see KH1, KH2 and KH3 in my phone info and I'm starting to get a little nervous that I messed up! lol
As far as I'm aware the code (XXKH3) (XWKL1) refers to the kernel?
The baseband would be the modem? If so, is this flashed with the rom/firmware?
How on earth do you decipher those codes?!
Thanks, and again, apologies if this is not a unique question but I'm sure the search feature is beginning to wear out now. If I had a touchscreen pc, there'd be a hole in the screen from pressing it so often!
The "codes" as you call them are just firmware version numbers
(Year)(Month)(rom number)
So KK5 would be a 2011 rom released in the 11th month and its the 5th rom built this month.
BVKH1
Bold: Country code
Underlined: Rom version
Baseband is the modem, you can mix/match any modem with any firmware (also our modem is almost unbrickable, had someone flash a i9000 modem and it was fixed by flashing a correct one ontop, but still be careful), there is no "best" modem, just find one that works for you.
Its best to keep your kernel and rom version the same, but it wont hurt to much if they dont match.
Recovery and kernel are fused together in samsung devices, so when you flash a kernel you flash recovery, so in order to get CWM you need a kernel with it (glad to see you worked this out!)
Dont worry about the base version, you can flash any i9100 rom on your i9100, the code is just a version+region code.
Also you dont need to worry about the region code, it doesnt have to match your region.
Also, this is a very good guide
ps make sure to backup your EFS asap, read that guide for more info!
Thank you very much!!
That's so much clearer And now I'm not terrified of turning my SGS2 into a plastic poptart let the fun begin!!

Stock roms: clickme and howto flash guide
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

Hi People,
After being a long time lurker on this board, I finally thought it was time to signup now that I'm in desperate need of some help. The girlfriend has been complaining about the poor battery life of her phone ever since she carried out the latest update. Now with that in mind, I thought I'd do what I've done with my ZTE Skate and that's change over to good ole' cyanogen mod.
So I downloaded Odin3 in the hope of unlocking my phone but when it comes to hunting around for the most appropiate Kernel, for one reason or another, I can't seem to find the one I'm looking for. The details are the following:

Could anyone please point me in the right direction? I've tried searching high and low but have came up short each time I've been looking. Hopefully, if there is one out there, I'll be able to use CF-Root 5.6 or something similar to change the Kernel so I can swap out the rap to something a little less resource intensive.
Any help would be much appreciated. I know this is my first post but I hope this isn't enough to put anyone off from helping me out. This is an awesome community and before creating this thread, I did search high and low but came up with nothing.
Thanks very much people! :good:
You're asking for a recommended kernel at the same time as saying you want to flash CyanogenMod (and "unlock" the phone?). Before you do something (else) stupid, you should do some more reading. Especially on the difference between a ROM and a kernel. Everything you need to know about CyanogenMod is in its own thread(s).
Apologies for my stupidity! Just when I thought I knew what I was talking about, I end up shooting myself in the foot. I'll take on your advice and do some more reading!
I am also confused about what exactly you are planning to do... What do you mean by "unlocking", and how are you going to use Odin for it? Is your gf's phone completely stock, i.e. not rooted? If so, the easiest way to me would be to flash PhilZ kernel and recovery straight from stock recovery (you don't need Odin for that, and it will not trigger the yellow triangle). This will give you root and a very nice touch CWM, which you can then use to flash CM (if that's your intention), or anyhing else you want...

Thanks very much kt-Froggy! I think I was confusing myself when I wrote my original post but somehow you managed to make sense of exactly what I was asking. Her phone is completely stock and I was looking for the appropriate kernel to flash. I'll give this a shot and see how I get on. With a little luck, it should be plane sailing! Cheers! :good:
No problem! Just make sure you get the right PhilZ version (the latest XWLSW) to match your current ROM. IMHO, it's by far the easiest way to get both root and CWM on our phones.
