No intention to immediatly burn you down when you're new here, but since you are new you should read the forum rules and the stickies first. Everything you ask is already explained hundreds of times, so don't start thinking about rooting yet if you don't know what you're doing.
As said above, first start reading and learning. It's the best way.

Welcome to forum!
You don't need to search so much to find how to root your device.. Well, i'll recommend you cyanogen mod, it's a very famous rom i've got installed and i love it. It works very well, it's JB, increases A LOT battery life.. and automatically adds rooot to your phone. http://wiki.cyanogenmod.org/index.php?title=Install_CM_for_i9100
You should read guides and stuff, for learning more for your device. In the top of this web, there is a text box to search posts, threads.. If you type in "Custom ROM" you will find a lot of useful information, do the same with all that words you don't understand.
In the bottom of every post, there is a button called "Thanks", if this post was useful to you, click it (just information ). You should do it with every post useful to you, but there is a limit. You should read this post for learning the rules and other forum stuff: http://forum.xda-developers.com/showthread.php?t=1699450
EDIT: I forgot, please read about root, don't root the phone without knowing what is it. Check en.wikipedia.org/wiki/Android_rooting

Got a Galaxy S2. Now what?

Hello. I came here from the Xperia X10 mini forum, because i just got a S2
Thing is i don't know what to do with it. With the SE it was different, I was a SE user my whole life, so I was up to date with how to do things on SE droids (root, flash with flashtool, etc.). But i have 0 experience with samsung.
I have:
PDA: I91000XWKE2
BASEBAND: I9100XXKDJ
KERNEL: 2.6.35.7-i9100xwke2-cl187606 [email protected] #2
It's running droid 2.3.3 and I cant update with KIES because it gives me windows encountered a problem etc etc... the old send dont send but on windows 7 (x64).
So I would like to flash it to a 2.3.5 rom and root it. Can anyone explain how do I do this? I don't know what and where to search because I'm new to samsung.
So far i have downloaded ODIN 1.85 and a found this "GT-I9100_OXA_I9100XXKI3_I9100XXKI3_I9100OXAKI3" file. What do i do with it? (also explain steps plz).
I never had a smartphone in my life before I got my SGS2, and I managed to flash all the ROMs without creating threads with questions that are answered in stickies. But maybe I'm a genius, not anyone can be one.
So, try here for starters.. or just search around.
install this kernel and read all the texts.
http://forum.xda-developers.com/showthread.php?t=1103399
You should now be root and have cmw recovery, and you can flash pretty much any rom you want.
Not to familiar with teh sony's but i assume you had clockwock mod recovery?
Odin to flash, cf root to flash as kernel to allow root and get cwm, cwm to flash a custom rom as a quick guide on what to search. Generally reading around will help.

Ty for the reply guys. Really apreciate the help and am reading everything you posted.
But 1 thing: witha ll respect, stop acting like I'm using up your personal space, I opened this thread for a reason, because i dont understand sh!t, and reading wont help unless i start to read the very beginning.
When i was at the Xperia thread, i used a program called Flashtool to flash a new generic rom to my X10 mini pro. It also updated the baseband (and basebands where important when i flashed a custom ROM, you needed to have latest baseband and kernel to flash X,Y,and Z custom roms).
I just want to update to the original samsung 2.3.5 ROM with odin (as kies sucks and wont work) and the rest will be easy. Don't want CWM and root yet, just a plain stock 2.3.5 rom. I just wanted to know if i can flash THAT file (first post, long text) to my phone with ODIN.
Again, thank you very much for the support, and will continue to read everything you guys post here.
It's easy to say search for this and search for that when you know exactly what to search for. In my case, I dont even know where to begin. And i would like to finish this "job" in the next 2 hours, as after that its time to sleep :/

No offence mate but when I moved from an HTC to a Samsung based device I was a newb then to, coming from another phone to different methods to another new method I got to grips with everything just reading around.
To answer your questions, yes you can flash a stock rom using odin, all you need is to check out intratechs thread in original development section, as of now KJ3 is the latest 2.3.5 firmware, download a frankenstein version and read his thread which had a guide on what to put where.

Your original post mentioned you wanted to root it hence I gave you the easiest way of doing so is to flash cf root, searching cf root would have given you that thread plus instructions within that thread.

well i flashed that rom i pasted there and it worked. Was simple once i knew i need to put that in PDA and start it.
Yes i know about CF root and will be my next move. Thank you so much for everythingyou posted (again). And will REread every post again for extra knowledge. Need to forget everything i know about SE and learn new stuff.

[Q] Noob - Where to Start

Hiya guys,
I have a Samsung Galaxy S2 that I got this week. Im finding the phone is brilliant to use at the moment and works very well. It's alot better for me to use this device that it was when I had my previous phone which was an iPhone (don't shoot me)...
Anyway here we are. I've had the phone 4 days and i'm wanting to root it. The main reason for this is that I hate bloatwear. Samsung have filled it with all their own specific software that they find useful and I don't want that. All I want is a lovely OS with no Samsung to worry about etc.
Right a little about what i'm wanting. Ok so the phone is a Samsung Galaxy S2 GT-I9100. The andoid version is 2.3.4, the Baseband is I9100XXKI1 and the Build is GINGERBREAD.
Im basically wanting to install the exact same version of Gingerbread but without all the bloatwear. Is this possible? Im completely new to this so any guides and tutorials that you can point me to would be brilliant. Is there anything I should be wary of when rooting my phone etc.
I have been looking around on the net and from what I can see Cyanogen M7 seems to be the same version as what im on now other than you don't get the touchwiz.
Any help would be brilliant on where to start.
If there are any questions then please ask.
Regards,
Just freeze the bloat yourself, rather than trying to find a ROM with it removed.
Root via zergRush, freeze bloat with one of the apps on the market.
However, if you do go down the CM7 route, just follow the instructions on http://forum.xda-developers.com/showthread.php?t=1176411
Other things to look out for. If any instructions are telling you to make a nandroid backup, do it, and back up your efs folder. You can use Hellcat's kTool for that.
Ok thanks for your post. So i guess my next question is What is Rooting and what does it actually do to your phone?
Do I need to root my phone in order to install new Roms??
Also the link to the M7 *Nightly* release you gave me. Is that stable? I read on their forums that I should only look at installing their *Stable* release and be wary of their *Nightly* release as its still buggy.
Since your first post said you were wanting to root, I kinda thought you'd know why. Bad assumption on my part, I know.
Anyway, before you flood the place with more questions, have a read for a while.
FAQS/Guide/Additional Info For Rooting S2 - High level summary
[FAQ] GT-i9100 Galaxy S II FAQ thread
Also, there is no so called "stable" CM7 build for the Samsung Galaxy S II.
Hi again.
Ok so I've had a read through the links provided to me and Im positive i want to root my device so that i can install new roms and unlock the phone and such. So next then can someone suggest what method i should do next. could someone also tell me what cf-root and clockworkmod is? Im confused as to what these are.
Regards
CF will give you root and clockwork, you can then reboot into clockwork and flash roms. Just make sure you read everything thoroughly and be sure to avoid the repartition option in odin.

Thanks but could you explain to me what they both do? Im assuming that its better to use cf-root as it allows you to install roms also...
Love spoon feeding eh?

[Q][I9300] Where do I go next (after learning basics)?

Hi guys,
So I've had two smartphones: HTC Desire HD and now my current Samsung Galaxy S3 GT-I9300. My S3 is the first phone I've ever rooted and flashed a custom ROM on to.
Stock, Specs:
AP: I9300XXBLG8
CP: I9300XXLH1
CSC: I9300XABLG8
I have read the rooting guide (flashing CF-Root via Odin) and I've flashed two ROMs so far: MIUI and CM10. I suppose I could say that I know the basics of flashing a ROM on to my phone.
I'm on my next crusade in the technology world (coming from a web dev background) wondering where do I go from here?
I know how to flash a ROM, how about customising one?
Where can I find some form of documentation/guide on performing tweaks to a ROM?
Where can I learn the syntax?
How can I go about creating a custom ROM?
How can I reduce my chances of bricking my device (considering I've had it two months)?
I realise I'm probably asking a lot considering I've only ever flashed two ROMs and 2 days ago I was terrified by the idea, but I'm an optimistic guy looking for a new hobby
Any help, however slight, is greatly appreciated.
Thanks!
P.S: sorry if this has been asked before, related threads weren't much help!

Install android 4.2 on galaxy s3 (from Smartisan)

Hi,
I'm fairly new to android (recent iOS convert) and playing with roms, I got an international samsung galaxy s3 i9300 which was already rooted and I put the Smartisan OS on to it. After playing with it for a while, it's good but a little buggy in it's pre-alpha state, I'd like to put standard android 4.2 (not the samsung stock software) onto the device.
Would anyone be kind enough to tell me or point me in the right direction to do this please? I've googled and can find people rooting the device or putting other ROMs onto it but nothing that tells me how to put standard android 4.2 on it from the Smartisan OS it's on now.
Many thanks in advance for any help
Best,
Greg
Just flash an aosp zip via recovery and do a factory reset

thanks but I don't really know exactly what that means to be honest
Where do I get an aosp zip from and how do I flash it?
Best

This is what the guides and FAQs are for in general
Sent from my GT-I9300 using Tapatalk 2
I thought I made it obvious that I wasn't able to find what I needed in there....
Nope. You didnt mention "general" at all. You said you googled. Look in "General" - important stuff is stuck at the top.
Or follow the link a moderator posted to you in your duplicate thread.
We wont spoon feed you.
Or see the sticky fas and guides .
Any user who cannot find the basics and has not read them should flash nothing .
Saves bricking your phone through ignorance is why .

I'm just asking for a bit of help, a link to something relevant, is that unreasonable to you? I thought this was a help forum.
I've looked and looked and can't find anything on installing pure android from the smartisan OS
Lots about rooting and lots about installing new roms, nothing about simply putting android 4.2 onto it... Do I just need to root it? (mine came rooted with omega on it so I don't know if simply rooting would do the job)
It's probably just the correct terminology that I need to know, is all.

No its a developers forum and users get tired of the same questions day after day .

Root does not put on a rom .

Want to root my S3, I am completely lost. Please help!

Hi, first of all I apologize if this kind of thread is against the rules.
I just made my account here and I want to learn more about rooting, custom firmwares and stuff. I was interested in formatting my phone, and install Android Lollipop (newest version, which is 5.1.1 I think), but searching through the threads in this forum is leaving me confused. Could anyone please point me to the best tutorials on how to root my S3, and how to install Android Lollipop 5.1.1?
Again, I apologize for my noobish brain. I literally just entered into the world of phone rooting xD
Thank you for your time.
