Rooting Samsung Galaxy S2. New at this, please help. - Galaxy S II Q&A, Help & Troubleshooting

I'm curious on if it's possible to root my Samsung Galaxy S2. The information of it is:
Model Number:
GT-i9100
Android Version:
4.0.3
Baseband Version:
I9100DXLPA
Kernel Version:
3.0.15-I9100DXLPB-CL709089
[email protected] #3
Also curious on if it matters what the baseband is when rooting a device. I know the model, version, and kernel is what matters but not sure about baseband.

Welcome to the forum. Don't take what I'm going to say below the wrong way.

Yes. There are rooting guides all over the place. Some of them are even stickied. Rule 1 of the forum is to search before posting.

No. Basebands can be changed later. You can even use a modem that was originally shipped with Gingerbread while the phone is running ICS, or vice versa.

Use the guide by Rachmat.Theres a link in my sig.

Upgrading to Latest Official Firmware?

Hey guys!
I just bought a used Galaxy S2 I9100 and I love it!
It's the "factory international" unlocked one.
Even had to buy a wall adaptor for the European plug to work in Canada.
I would like to update it and trust me, I do search, but it's ever confusing!
The previous owner already rooted it, but I would just like to unroot it and go to official latest firmware. Starting fresh.
I visited this thread:
http://forum.xda-developers.com/showthread.php?t=1075278 and I know I have to get my downloads from there and flash with odin, but I have NO IDEA which one to download.
Here's my phone info currently:
Android Version: 2.3.3
Baseband Version: I9100XWKE1
Kernel Version: 2.6.35.7-I9100XWKDD-CL161513
[email protected] #2
Build Number: GINGERBREAD.XWKE7
I live in Canada and I'm using Rogers as my carrier (they don't carry the I9100).
I absolute love this phone so far but I would just like to get to the latest firmware.
Can anybody point me to the firmware I want to get?
Thanks folks, and have a happy holiday!

I'd look for the baseband version associated with bell since they do sell the i9100. They use the same baseband frequencies as Rogers.
kernels are interchangeable. Always backup your current ROM before upgrading for sure just in case. I've even gone as far as trying different modem firmware to try and improve signal strength and data speeds.
As long as you have a backup of what currently works you can't go wrong really
oops...didn't read the part about unrooting. I've never gone back to un root before but I think you can flash an unrooted kernel through Odin. Sorry I can't be of more help add to which one.
I'd still look for stock Bell firmware

I JUST finished updating my phone by downloading this:

Just checked my phone and it says:
Android Version: 2.3.6
Baseband version: I9100XXKI4
Kernel Version: 2.6.35.7-I9100XWKK2-CL726411
[email protected] #2
Build Number: GINGERBREAD.XWKK2
So far everything seems okay.
I noticed that the Voice Talk app crashes now after I say a command.
I also got rid of that yellow half screen problem!
I think my phone is unrooted now because I didn't see a yellow triangle at boot, but the thing that's weird is I still have the superusr app and in my Kernel version it says "root".
Do you recommend me reflash my phone to Bell firmware?
If I do so, wouldn't I get all the Bell branded bloatware stuff on my phone or no?

Just wondering, what baseband version are you running?

Automatic root?

Ages ago, I rooted my phone using an automatic rooter, but now I can't seem to find it. Can someone help me please?
If u are on GB then download Siyah 2.6.14.TAR and use Odin Method as described in other Threads.
If u are on ICS download latest Siyah 4.1.5.Tar same method as above.

About to flash the Siyah kernel

I'm about to get my SGSII in about an hour and the first thing I plan to do is flash the Siyah kernel through odin and gain root. Is there a way to backup the stock kernel without root before I flash this one?
Thanks in advance.
you dont need to backup the original stock kernel. you can download it anytime, just use the search function. i recommend flashing a matching stock rooted kernel for your firmware, then perform traingle away and then flash siyah from cwm.

OK, thanks for the good advice. I will definitely go that route since this is the first SGSII I've owned and you would know better than I do. Just for the record if I did it my way would it have bricked my phone?

After getting your galaxy s2,
First thing is to Post your firmware details here; Goto Settings - About phone, and post everything you see.
You might not need to flash any kernel at the end the day.
Happy Independence Day!

Anyway here is the info
Model Number: SGH-T989
Android version: 4.0.4
Baseband version: T989UVLH1
Kernel version: 3.0.8

Good.
1. Your device is T-Mobile variant of the Galaxy SII.
2. Flashing anything meant for GT I9100X including Siyah kernel will destroy your phone.
3. Visit the right forum for your phone, and continue from there: forum.xda-developers.com/forumdisplay.php?f=1329
Consider yourself very lucky!
Don't flash Siyah kernel at all
Happy Independence Day!
Wow thank you for saving me. Didn't realize there was a subforum for my phone. I definitely owe you one.

[Q] S2 update advice

Have a Mt8s s2 GT I9100
Build Gingerbread.XWKF3 2.3.3
Kernel version 2.6.35.7-I9100XEKF3-CL276555
[email protected] #2
Baseband version I9100XXKE7
Could someone kindly advise me as to the latest and safest Android Version to update it to, with a link to file if possible.
reading so much about the s2 bricking and couldn't sort the other Mt8s stuck at boot problem am a little weary and welcome any advice.
Thank you.
Every Andrioid version is safe.
The only kernel that it isn't is 4.0.4.
So there you have it.
And don't even think about asking which ROM should you flash.

[Q] What kernel to use for XXKI4, confused about all the ROM's

Hi all,
It seems to be important to choose the correct ROM.
I have a rooted device with an XXKK2 kernel (CMRoot)
Now I want to upgrade to Jelly Bean and so I need a newer kernel.
But: can't find a kernel for XXKK2.
How can I decide what kernel to use?
And is there an explanation what all these chars mean?
Chainfire mentiones I should care about the KK2 part, but it seems there are no ROMs for ICS on this radio...
Is that true? Is the device too old?
Thanks a lot for your answer!
Pedor
More info pls go to Settings then about phone. Them details please.
Pedor you dont seem to know basic information,which is resulting in you posting total crap lol.
If you want a rooted JB setup,then go to sammobile and download a jb stock rom for your region etc,then flash philz kernel for jb.
-------------------------------------------
maybe your an iphone expert
------------------------------------------
@ OP we don't use CF Root with our S2 since the whole brick bug drama.
We now use ExynosAbuse (ICS only) , SU + BusyBox + CWM or a custom kernel like siyah ir the above suggestion.
You got the EverRoot option featured in Chainfire's Mobile Odin Pro.

There is a clue in the 2nd paragraph of his opening post.
And he was told what to do in my previous post.

I didn't read it well. I was going to say follow what you posted. With use of what gastonw said about mobile Odin ever root option. But philz is cool to though. More work for op though
His desires didnt make sense to me.He wants a newer GB kernel for JB lol.He doesnt mention whether he wants stock or custom.

Id say stock at a guess.
