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.

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] Stock KERNEL (not firmware) required

I've posted this before but I didn't really get the response I need so am trying again but just clarifying what I'm asking for.
Stock KERNEL for SGs2 ICS. This is the KERNEL not the ROM. Please don't post a link to stock firmware
I've tried here:
http://forum.xda-developers.com/show....php?t=1075278
but no links work (it always says no longer available or copywrite infringement)
Thanks
1) You absolutely did not need to make a new thread. That's called spamming the board. That's a cardinal sin on here. Mods will be closing this soon.
2) Before they do, you haven't specified what kernel you need (Don't tho, it doesn't really matter). So what I'm going to do is give you a link to a site you can get entire roms from, and you can extract the kernel (zImage) you need from the rom yourself. Try here or Samfirmware.com.
Sorry and thanks
..
Locked. Please don't spam the forums, and read before posting.l
Cheers

[HELP]How to go back to official ICS?

I bought my S2 with official ICS 4.0.4 in it and I wanted to try Jelly bean so I flashed XXLSJ with odin, i replaced the PDA, PHONE and CSC..
I don't like it and I want to go back to official... Can somebody give me the latest official ICS? I have been searching for hours here, found one that has only the PDA file... phone won't boot with it...
Have you tried the FIRST post of Original Android developemnet section? either way: http://forum.xda-developers.com/showthread.php?t=1544487
choose the one you had before and it should work out.
Regards.
Just give me the link to the latest one that can be updated with Kies.

Firstly, ever thought about saying "please" instead of just demanding? This isnt your personal tech support site, its a community of smartphone/tablet enthusiasts and developers.
Second, How do you expect anybody to be able to link you when you dont even give such basic info like what model your actual S2 device is?
Third, Rule #1 of xda rules says you should use search before creating topics as its extremely likely you topic has already been created so no need to be re-created and that is the case here. If you had searched you would find the topics that have the stock carrier roms or people linking to http://www.sammobile.com/firmware/?page=3.
In future please respect XDA and use search and have courtesy when asking for help instead of demanding it.

[Q]4.1.2 on XXLPQ

Hello everyone
I have bought a SGS2 GT-i9100 and i was searching for 4.1.2 frimware for my devie. My PDA It's XXPLQ and i searched it by Samfrimware and didn't found it. My question is: There's 4.1.2 for my device? Or dosen't matter if it it's XXLJS or another version.
I don't know if this is necesary but i'm from Venezuela.
Try to search here. Link

Why would you link someone who has clearly stated they have an I9100 to I9100G firmware ? You do realise a lot of people who ask for help here take whatever help you give them rather literally & tend to blindly do what they're told without thinking ?
I hope for your sake this guy doesn't download one of the firmwares you linked to & flash it, you owe him a new phone if he does.
Edit - OP, you're very confused. There was only one 4.1.2 I9100 stock firmware released for Venezuela, which is available on Samfirmware - VNO - I9100UHMS8. There is no 4.1.2 firmware XXLPQ. You can use any stock firmware from any carrier, it doesn't make any difference. However, you seem to be completely lacking in 'the basics'. If you attempt to flash anything with your current lack of knowledge, you're asking for a busted phone. Read the guides/tutorials stickied near the top of the General section before you do anything.

You don't need to be rude here. Everyone does mistakes. And yeah i didn't notice about I9100, and i already edited the link that i provided before.

[REQUEST] Valid links for root and CWM/TWRP

It was not my intention to spam,
and I hope I have not miss any message that had them, but I can't find any valid link to download the root and recovery zip files. All link are dead.
But I see modding is still alive here, and I have to admit this makes me very happy about that, so, can anyone upload those files? I resurrected this phone after my Nexus completely died, and I would like to mod it, since the stock ROM is not that good.
Thank you, and sorry again for this strange post.
Please explore around here: http://www.xda.mister-freeze.eu/XDA-files/
Most development stuff are kept there for ace2.
Also check out more in ace2nutzer's thread from where I copied that link from.
