Hi everyone, i've acquire recently a Samsung Galaxy S2.
I came from LF P970.
I would like to know, the best and safest way to ROOT my S2, and Tools and procedures needed to flash new rom.
And yes i've used search and also the INDEX of guides and tutorials, but there are too many for the same thing, so i dont know which one i should use.
Best regards,
ruibullseye
Flash a kernel through Odin to root it. Flash a rom through CWM. All of the details are written down in the guides.

First learn how to flash using odin. There are so many guides on xda and other forums. make sure you install samsung kies and have proper drivers for your phone. Then flash siyah kernel v5.0.1 using odin..Then you will easily get root and CWM recovery

I am new to the android .and bought my first galaxy s2. I will follow the s2 one click root to root my phone. I need to know if I need the same kernal as my device? My original kernal is JPKG5. do I need jpkg5 insecure kernal and then a jpkg5 secure kernal to root my phone? Or can I change my kernal to some other kernal of my choice?
my galaxy s2 gets pretty hot if I play intense games like asphalt or star legends, it even gets hot if I use mobile internet like EDGE (i guess its 2g internet nott sure) and browse the internet. The battery life sucks. I keep wifi, gps off and it last like 7 hours if I use mobile internet. Heard a different kernal might help.
One last question, what is the purpose of titanium backup? Do I get to restore my phones original self back again easily? Like will it unroot itself and return to the original gingerbread rom if I decide to change to cynogenmod? If titanium backup does not do that, then how can I unroot my phone and then get back to my original gingerbread rom?
Thanks alot for your help...

Welcome to Android I am not sure about the kernel. The purpose of TB is that you can backup all your apps and data and if you flash a new custom rom you can use TB to restore all the apps and data. Its a very powerful application. You can always flash the original stock rom downloaded from Intratechs thread http://forum.xda-developers.com/showthread.php?t=1075278. Then you will have an unrooted phone. Beware of the custom counter!!

If you are international S2 (i9100) user use CF-Root instead SOC:
http://forum.xda-developers.com/showthread.php?t=1103399
Dont use CF-Root or SOC if you are AT&T user, there is specific threads on how to root AT&T devices.
CF-Root is 1 step only, this means for a non experienced user like you (as it's your first android device) less chance to screw up something.
Follow carefully the instructions.
Be sure Kies installed but NOT running (kill kies process) because kies block odin = semi bricked phone.
Takes about 30 seconds

im a bit confused, all those stock kernals in that link u gave are kernels and rom? Like if I have cynogenmod rom installed in my fone and then flash my phone again using one of those stock kernels/roms, I would be flashing back from cynogenmod to gingerbread 2.3.3 (JPKG5)?
Also what is the custom counter?

sorry for the multi reply post, dont know how to quote 2 messages in one reply...
Cf-root seems like it will limit me to only one kernel, is it a fact? Is it possible for a gs2 user to use any kernel he desires? because I would like to use a better kernel than jpkg5 but stick to the original gingerbread rom 2.3.3. Then mod it to stop loading the so called bloat somehow using an app. Plus I found cf-root to be a little confusing, can u help me understand this? Cf-root will use the kernel inside the phone and leave it intact plus give me root? Or will cf-root change my kernel permanently?
Thanks for all the trouble everyone, if its ok ill ask more questions if I get stuck, but will try my best to figure it out myself first...thanks again...

If you flash one of those ROMs you will flash from cyanogen to your original. The custom counter counts how many times you flash a custom rom / kernel - it can be a problem if you have to send your phone in for repair. Read more about it.

cf-root is an original kernel with root+cwm inserted. No it dosnt lock you to a single kernel, its just the most easy way to root your phone while keeping your stock rom. When you are rooted you then can flash any kernel or custom rom you want.
You only need to pickup the same (ex: kh3, ki4, kf1 etc..) for the root process, this to have full compatibility during root with the stock rom on your phone, but after successfull root you can flash any kernel/rom for the s2

As Wezza said, CFRoot is the easiest & most hassle-free root method for SGS2. Takes all of 2 minutes, very remote chance of stuffing your phone up so long as you follow the instructions. By your own admission, you're a 'complete newbie with Android', and IMHO, using a method other than CFRoot to root your phone is just making life unnecessarily complicated for yourself.
Just my (and obviously Wezza's) opinion tho.

Hello guys,
So, I decided to install another ROM on my Samsung S2 i9100G - thats why I went to different forums and found so many ROMs and Kernels and Tutorials, that I'm not sure, which one to use (and where the files are up2date)
Ive got a German Model with 2.3.6 (I9100GXXKL4)
and my kernel is on 2.6.35.7
I'd like to use CyagenMod (dont know the exact name) 4.0.4 on my Phone and I already downloaded Odin - but "damn" im scared as hell to brick something with the wrong version lal (I flashed my nokia 5800XM and it was a hell of work )
and do I need to install any kernel? where is the difference between the ROM and Kernel? can I just install a new ROM?
greetings

edit:
DO I need to ROOT my Phone?
and: Is a SD Card neccesary or can I use the phone one which is integrated (16GB)
Third Question: Can I use any Kernel I want? As far as I know now, I need to Root my Phone flashing a Kernel via Odin (I will use Lucifr)
But its a GB Kernel, right? So I cant use any ICS ROM?

If you don't want to root go to www.sammobile.com and pick a ics firmware. They have flashing tutorials. But honestly I wouldn't do anything until you do some research.

Before you do anything to your phone, DO NOT INSTALL A I9100 International firmware.. You have a I9100G, It is not in anyway compatible to the intenational phone. READ THE STICKIES FIRST PLEASE.

Hey I have a couple of quick questions on flashing. First question is what does Odin do? It looks like it flashes roms and roots your phone. Is that correct? If I brick my phone somehow can that unbrick my phone? Another question is what is the main way to flash roms on the galaxy s3?is it Odin? Clockwork mod? Twrp? Is twrp and good manager even supported on the galaxy s3? Thank you for all of your help.
Also I know that this is a subjective question but what rom should I start with? Which is the fastest and most feature rich rom with little to no bugs?
if you dont now know what Odin is you should not flash yet. You can flash a .tar Rom using Odin and a .zip using cwm. Most of the custom roms are available for cwm flashing. All the stock roms are available in tar format I.e. Odin flash.
Subjective ans to your subjective ques... The best Rom available is stock IMO

Odin cannot root your phone. Is just a software to flash .tar file into your phone. Most people just use CWM to flash roms.
There is no perfect rom. Just try flashing until you find the right rom for you.

Could do with a little advise. I have rooted in the past, most recently my HTC desire. I used to flash roms all the time.
Anyway I have decided to root my s2 and I am having problems. I root view odien and everything goes fine but when it reboots everything is the same and have no root access? any ideas?
If it helps I did the manual ics update a while back, don't know if that has anything to do with it?

You're not really explaining the steps you took to root. Flashing a CF-Root kernel through Odin would usually do the job if you want to maintain stock ROM. Otherwise, flashing a custom ROM would also give you root access as most ROMs come with it built in.
I strongly suggest you explain further what steps you took to flash. Because root view odien doesn't say much and is quite confusing.

I could say flash siyah-s2-v4.1.5 via odin(which gives root/perm cwm and safe kernel).
But I wont til you post the details.....

It has always been my preference to root through a custom kernel... If you do decide to go this way, download siyah v4.1.5 and flash it through the PDA section of odin.
Also, as theunderling said, please post your phone details before flashing.
Flashing this kernel will grant you root + permanent CWM

If you followed this tutorial you are already rooted on 4.0.3. If you want to upgrade to 4.0.4 I recommend to flash a stock 4.0.4 via odin then Cf-root (or other prerooted) kernel to have root, custom CWM recovery and be safe from brick bug. Then flash desired custom rom. Yes, custom roms come usually with root.

I haven't mate. I downloaded root checker and it says I don't have it.
No you don't. Flash the TAR ( NOT zip.) version of siyah or dorimanx kernel via Odin. You don't need CWM for this. Once you install one of these custom kernels you will have root and CWM and can then install a ROM and whatever else you want via CWM.

Theunderling is not so much patient for new members
It happens everytime you flash custom software to your phone via PC odin.
Use Triangle Away app from Google Play store to remove it. However read carefully the app instructions before you use it.
