I want to unroot my phone back to a normal new one and I dont know how. Please I need help

Give the forum search function a go and you'll find plenty of threads detailing steps for unrooting.
Worst case.. give Google a go and it will find it for you

Download stock firmware from http://sammobile.com/firmware/, unzip, flash in PDA via Odin.

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.

Find any firmware for the i9100 you need at www.sammobile.com, or through the CheckFUS downloader.
Not sure what the fact you have an i9000 has to do with this at all, though...
and with regard to odin and the root?
You want Odin ? Google it.
So far as root is concerned, CFRoot is easiest but do not rush it. Read the first page of that thread carefully, particularly the bit in bold red that says 'Help ! Which file do I use ?'.
If you read it, then come back to this thread & ask "Which kernel do I use ?", that tells me you haven't read the CFRoot thread carefully & you probably shouldn't be rooting your phone/you're at risk of bricking it.
If you do read that thread carefully and follow the 10-12 steps to the letter, rooting your phone is simple & takes a few minutes. There's nothing complicated about it if you can read/follow instructions.

[Q] Rooting ICS 4.04 on SII GT-I9100

Dear XDA,
I am sorry to bother you, as I am a Noob. But I've watched the video, searched the Wiki and looked in the forums.
It may be that I am stupid, and I am sure it will be pointed out to me in the comments, but I cannot find a guide anywhere on how to root my handset for the latest firmware upgrade 4.0.4, just snippets of information that I cannot bring myself to trust enough to risk bricking my phone.
My deets are:
GT-I1900 on T-Mobile UK
Android 4.0.4.
Baseband: I9100BVLPE
Kernel Version 3.0.15-I9100BVLPH-CL969772
Build num: IMM76D.BVLPH
Does anyone know where to find a good guide to doing this, or have any advice on how to do this?
Best,
Sam
Hey
You just have to flash a rooted kernel for 4.0.4 via Odin, then your phone will be rooted.
Boot the phone into download mode, in odin put the .tar into the pda field and flash it

Just look in the General section for the S2. There are guides for how to root your phone with Odin (or another method but that is the most common as far as I know) by flashing a custom kernel. It may look difficult untill you try it yourself.
Just make sure you follow the steps correctly. And before all this, search for info about the emmc brickbug before you start rooting, just to make sure you minimize the risks when you start the procedure.
Good luck.

I appreciate that you may be confused but we have plenty of topics that very clearly and specifically tell you how to root your device. Your problem is that you haven't read/researched enough and want spoon feeding by creating yet another "how do I root" topic.
If you want to root you just need to reboot into download mode and flash custom kernel like Siyah (.tar) as PDA (make sure re-partition is unticked).
Check these first:

[Q] Cyanogen 10.1? What is it exactly?

Wow - this forum is huge
Although I am new to Samsung Galaxy S3 I am prepared to work for it. I just don't want to start flashing unstable files. Which is why I thought I would ask here first.
Question
I have just purchased a Samsung Galaxy S3 i9300 and I have rooted it yesterday via Odin and in my apps I can now see CWM V3.60 and SuperSU Now I am looking for some advice please?
What is Cyanogen 10.1? I have been reading about it but don't fully understand? is it for installing Roms that supersedes Samsung software 4.1.2? and is there a safe tutorial you can point me to?
Also I want to get rid of the bloatware on this device can anyone please point me in the right direction of how I go about doing this?

The bloatware thread in Themes and Apps or flash a custom rom with bloatware removed .
Best to read all the faqs and guides before starting .

Go read the sticky thread in general forum, CF autoroot then backup your efs. Install a custom recovery to flash your custom rom.
Follow the guides exactly, it's quite easy to brick these phones.
