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.

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.)
hi guys - finally decided to take a look at rooting and getting cwm on to my s2 to give it some custom loving.
need a little advice on what cf root version im needing as some of the numbers etc look similar to each other with varying letters that im not sure of.........
phone details are:
gb 2.3.4
baseband i9100xxki1
kernel 2.6.35.7 - i9100xwki4
build xwki4
i can see variants of xwki4 (ie nee v4.1, 42 v 4.2 etc etc) but id rather get it right first time as il get hung by the mrs if i screw it up lol
cheers in advance and if anyone wants to suggest a rom
scotty
I don't know about CF-root. I used superoneclick, but I suggest to use cm9 if high battery consumement and some bugs aren't bothering you, if they are, I suggest to use GalaxyZerox if you want to get nice ics look
I don't think it really matters what kernel you flash to root it. I think its just advisory to get one that closely resembles your original one when first rooting. As once its rooted, when you flash a different rom they come with a kernel anyway and most people on here seem to always be experimenting with different kernels.
Hopefully someone else will confirm this.
I'm fairly new to this but it really isn't that hard as long as you follow the instructions from wherever you get them from.

cheers guys - all done! just went for it and alls good.
appreciate the responses.
rom time yeehaa
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.
Hi Guys as my title Says..
i need Help very Badly.
First of all MODS and USERS i'm sorry i didn't knew where to post this thread so if its in in-appropriate section please move it to correct section. THanks
OK my problem is this.
i recently (less than a week ago ) bought a Samsung Galaxy S2 its by Bell Canada and its i9100M. i bought it online since my service provider is Rogers.
i guess this phone is already rooted to unlock it and i can see CWM and SU icon there.
Well i'm a Hardcore Blackberry Fan and have been using Blackberries from last 6 years. I loved the new samsung because of it looks and its screen.
I Had Lot of Problem with it like setting up my yahoo as push email, setting the Ringtone Profile, setting up the Custom Ringtones for Text Messages..
Having wrong time stamps on Recieved TEXT Message.. well i fixed all those by installing apps from market and forwarding my yahoo to my gmail...
i Hated doing all that but infront of the beauty of this phone i had to compromise but today it took 3 hours to find my gps location and day by day im using it i'm hating it .....
SO OK I DID MY RESEARCH AND FOUND OUT ALOT... the more i'm researching the more i'm getting confused...
first of all what is the difference between custom ROM and KERNEL.
i know custom rom could be like operating system but customized by unofficial person.
what the h is KERNEL..
to install rom's or kernel do i really have to root.
To unlock do i have to root or is there a paying method.
also i want to know if i'll go back to stock rom can i still unlock it.and recieve all the updates from samsung or google specially when ICS will be launched.
after unlocking and installing custom root. can i unroot it
and lastly which is best custom kernel and which is the best rom availble.
since been a blackberry user i have very basic needs. i don't play any games or download much apps and if an app is paid..i'll pay for it.. i don't want to jailbreak anything .
all i need is better battery life, gps and network coverage.
Thanks for taking time to read and reply.
Hi there.
I'll try and get through your questions as simply as possible,
Imagine your phone is like a car
A kernel is like the engine of a car - it's the low level machinery that keeps it going.
The Rom is like the body of the car around the engine. Roms can be official (or Stock Roms), or they can be customised by other people.
So, when you install a stock rom - you're installing the kernel, but you're also installing the radio (called a modem or baseband) and the registration (or the CSC which is location specific information) as well as the unique 'body' of the car for that rom - tweaks, default software, etc.
You don't have to have rooted your phone to install a Rom. When you update your phone via Kies, you are, literally, installing an stock rom. You can even install stock roms from elsewhere without rooting your phone. Because stock roms are released in different regions at different times, lots of people update their phones to the latest official roms via this method - no root required.
However, to install a custom, unofficial rom, you will need to root your phone as they will require access to the 'root level directory' of your phone's file system - which is what root really means.
You can find everything you need to know about that, how to root and also lots of stock roms you can install without rooting here:
Some shops will root you phone for you if you want to go down that path and don't want to risk it. But it's easier than you think and the galaxy s2 is very hard to break. There's lots of help available on XDA - just remember to search before you ask so you don't ask a common question the millionth time.
If you have installed a custom rom you can easily re-install a stock rom over it that will still work with Kies and thus be updateable when ICS turns up.
There is no 'best' Rom or kernel. Some Roms go 'as is' and some are customisable to the nth degree if you like fiddling with your phone non-stop. I personally use CheckRom because I like the kitchen app that lets you swap kernels, modems and mods with ease - but check out the Original Android Development threads and see which other roms you like the sound of.
Depending on what you are currently running, a new rom - even a stock one if you're running a very old one - could easily help with battery and range issues. For GPS - try installing FasterFix from the market and see if reassigning your GPS fix to a closer location helps.
Best of luck - it's a great phone once you open up its possibilities
Thanks a lot for the reply
well your reply did help me a lot...
my phone is been already rooted by someone else already from the person i bought it....
as for searching i did a lot.. and its been confusing me more and more ..well thanks for your answer
also as u said S2 is hard to break..i guess u mean is that the JIG thing on EBAY
and as for flashing the stuff i've played with other stuff just not android thing ive replaced the os on BB and jailbreaked iphones and installed macintosh on HP PC and also worked on most of the languages 10 years ago... and i believe nothing is impossible so going to someone else is never an option for me
just want to know as much as stuff i can before going further
well i have few more questions
how can i find which rom or kernel is already installed...
i mean is it possible to tell if its stock or its customized and its customized by which group.
and one last thing.. u know the words u used modem and baseband...
i read about it before...
but my question is ...
IS THE BASEBAND ANYTHING LIKE IPHONE BASEBAND???
u know in iPhones when baseband is updated u r screwed sometimes its hard to jailbreak and definately hard to unlock and reverting changes to baseband....
is it the samething in Galaxy S2 as well...
Thanks a lot for replying...i really appreciate all the time you took to reply.
Thanks once again.
Yeah baseband is the code that handles the phone part of your smartphone. Talking to your wireless provider, 3G, texts all these things are done by baseband.
Flashing a different baseband won't screw your root, and you'd still be rooted. Samsung doesn't make it hard to root as Apple does to jailbreaking. Even if something goes wrong with a new version, you can always revert back to old one using Odin(Samsung ROM flashing tool) and you are good to go.
Thanks a lot... about that quick reply...
i'm gonna collect more information and hopefully i'll be flashing it on weekend...
but how can i find which rom or kernel is already installed...

Everything you need to know can be found here. Most of it, anyway.
Backup your device with cwm when rooted ... So you can always restore to previous state. ;-)
Good luck there. But reading is a must.

also you can go settings - about phone - then look at the bottom fields to see kernel, baseband and build. Quote those and we should be able to tell what you have.

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??
