[Q] Questions about new Galaxy S2 International on ATT - Galaxy S II Q&A, Help & Troubleshooting

Hey all,
Just got the Galaxy S2 Internationl GT-I9100 and I'm using it on ATT in the United States (it is NOT the ATT version).
The info:
Android Version 2.3.3
Baseband Version I9100XXKE7
Kernel Version: 2.6.35.7-I9100XWKF3-CL276555, [email protected] #2
Build Number: GINGERBREAD.XWKF3
So I have a couple questions:
1) Will CF-Root v4.0 for KF3 work on this phone? Is there a later version of CF-Root for KF3?
2) Does it matter that baseband is KE7 and kernel is KF3?
3) Does the S2 brick easily? Soft brick that can be reversed by flashing stock with odin (like on my captivate) or hard brick?
4) My plan is to install CF-Root, then backup /efs, and then flash cognition. After backing up /efs, can I just flash cognition using Odin or do I need to use CWM?
5) I noticed that cognition uses the Ninphetamine kernel...will that be compatible with my phone? Will most custom ROMs be compatible with my phone?
Thanks for the help guys! Now that I have an S2, I can use my captivate to muck around with the android source =D

May not be relevant but
How about trying to update to 2.3.4 stock ROM before going root. Personally I don't feel much need of rooting after switching from galaxy 1 to 2. Fast enough.

I've always been a bigger fan of community developed software than stock ROM. Also, I want titanium backup and few other things even if i just stay on stock rooted

New SGS2 needs rooting, please

Hi guys & gals,
I've *just* taken delivery of a new Samsung Galaxy SII running
Android 2.3.3
Baseband I9100XXKDJ
Kernel 2.6.35.7-I9100XXKDJ-CL187606 [email protected]#2
Gingerbread XWKE2 build
I've successfully flashed the kernel of my previous SGS1 to root it using CF-Root via Odin.
I believe I'm looking for a KDJ version of the CF-Root, but can't find one.
Any help / pointers would be much appreciated as unrooted, the phone's just no fun! And I can't use my Titanium backup.
Thank you
Dave
No need to find KDJ or specific. Just find your PDA version and flash that kernel.
I hope you know how to see PDA version,
*#1234#
Regards.

You may want to update to a newer rom, look in this thread, then select a correct version of CF root.

[Q] Returning Rooted Galaxy S2

Hi. Got a GSII from T-Mobile a few days ago and (obviously) went ahead and rooted it. Then I noticed I had a dead pixel and T-Mob are going to swap it over since I'm within the 7 day period. I have unrooted and used the GS jig to reset the insecure kernel download number. I then downloaded a secure kernal and flashed using Odin.
In my settings, however, it still says:
Baseband version: I9100BOKG1
Kernel version: [email protected] #2
Build number: GINGERBREAD.BOKG2
Would anyone be able to tell me how I get that information to show I have an untampered with device? I feel like I'm missing something pretty simple (or it can't be done)
Thanks
ps - sorry if this has been discussed before.
What is the kernel you used to flash back to stock?
Flash a full stock rom not a kernel .
Reset rom counter to zero with usb jig .
Thats all you need to do .
They might query KG2 firmware with KE2 kernel instead of matching KG2 kernel .

[Q] ICS dilemma

Hello everybody,
I have a SGS2 from Bell Canada. I upgraded the stock firmware following various guides here. I managed to root it and to unlock it using Galaxy S unlock from the market.
The phone is running well now, battery life is about 2-3 days (I have Juice Defender and it helps).
I would like to upgrade to ICS but after reading a few threads I am very confused...
My first question is: will I lose my unlock?
Then, Kies does not recognize my phone any more; should I flash back to stock and wait for ICS to be available for my carrier and take it from there? Or should I go through Odin and just flash one of the ROMs released for Europe (or another region).
I am even willing to pay for Mobile Odin Pro and flash it directly from the phone, I read that it's safe and you don't lose any data, although other people were saying that it's better to just start from scratch.
Right now my phone info is the following:
PRODUCT CODE: GT-I9100LKMBMC
pda: I9100XWKK5
PHONE: I9100XXKI3
CSC: I9100XEUKH2
Model: GT-I9100 (shouldn't it have a M at the end?)
Android version: 2.3.6
Baseband version: I9100xxki3
Kernel: 2.6.35.7-I9100xwkk5-CL754841
[email protected] #2
Build number GINGERBREAD.XWKK5
So, could anyone point me to the right direction?
Thanks in advance
I think you have the international sgs2. I have tried flashing the xxlpq ics update and then flashed a custom rom but I encountered a lot of issues. I think the ics update still has lots of bugs so I rolled back to gingerbread using checkrom revoHd v6. So as of the moment all you need to do is root your phone with Odin and CF-root kernel and wait for a stable ics rom

You have a whole lot of options to play with, it all depends how comfortable you feel and what do you want.
For starters, you have upgraded from KG2 to KK5, which is a firmware other then Bell, as Bell never released and update. Because of this upgrade your phone says it’s a I9100 and not I9100M. Mine says the same after I upgraded as well.
I updated my Bell KG2 to ICS (LP7) and so far I don’t have any problems with it. I did have an issue with calls going straight to voicemail, so I installed the LPQ modem, and things have been well. People have complained about battery life, but I don't think it’s bad. I would say pretty close to stock GB if not better.
What you can do is make a Nandroid backup and then upgrade to ICS. You can do it through Odin Mobile if you like, as it won't upgrade your Custom Rom Counter, if that is an item of concern to you. There are other ways to clear the custom rom counter, if you go through ODIN.
I would suggest doing a factory reset with CWM, and clear cache/dalvik cahce. This will be like setting up a new phone. You can also upgrade without the reset that and it will keep all your settings and unlock. You will lose root though, but you can re-root.
I have done it both ways, and I went with the reset in my 2nd try just for my peace of mind. I didn’t have any problems without the reset either.
If you don’t like it, you can always go back to your Nandroid backup, which is what you currently have using CWM.
If you want original bell firmware, then you have to wait until bell releases it.
In the end you are the one to decide. Hope this helps.
Once u unlocked network it won't relock after u flash/update software

Hi everyody, thanks for the answers...
I guess I want to try the stock first and then move on to some custom roms...
I read a thread about the XEO Rom and was going to try that
What do you think about this?
@sahib - thanks, I was not aware of that...
@warhawk_la - thanks a lot, very helpful bits and pieces; what is the difference between the LP7 rom and the XEO and where did you get the files from (I see tht you flashed a different modem)

NO its un locked .

May not work as Kies needs correct codes .
Or should I go through Odin and just flash one of the ROMs released for Europe (or another region).
Your choice but rom for your region and actual phone is always best even as a backup for warranty .
Personally i would not jump on the ICS bandwagon yet .

Help needed please

Hey guys,
I'm a real noob at roms, rooting etc but i followed a tutorial on Youtube which lead me to root my phone using Odin and Superoneclick. I have no idea what this did as i didn't notice a difference on my phone but now ICS is released for my Galaxy SII which is TmobileUk branded. However, when i check on Kies, it says New Firmware Is Available but when i click Firmware Upgrade button then nothing happens. When I click Firmware upgrade and initialization under tools i get the error GT-I9100 does not support initialising. When reading on forums i found out this is because of me rooting so i searched on how to unroot Galaxy S2 but everything comes up with Unroot and installing Stock Kernal etc but i am not sure if i have installed a kernal but i can remember i put XWKDD file in ODIN.
Android Version: 2.3.3
Baseband Version: I9100BOKF1
Kernal Version: 2.6.35.7-I9100XWKDD-CL161513 [email protected] #2
Build Number: GINGERBREAD.BOKF3
and i have no MOD VERSION which i fugured is for a rom.
When typing *#1234# i get these versions:
PDA: I9100BOKF3
PHONE: I9100BOKF1
CSC: I9100TMUKF1
I have read some posts and found UK Tmobile have BOKF3 etc from http://forum.xda-developers.com/showthread.php?t=1113928
but i do not know what todo with it.
Also i just installed an app called Ginger Unroot which has unrooted my phone so if i need to root or do anything can you explain please and will any of the steps wipe my phone (apps, data etc)
I really need this help
Thanks in advance
RE
Im real desperate
What most people do one they root their phones is install ROMs based off of the official release. It's like getting the release, and guaranteeing root access. I think that's a better way. You have more freedom. Otherwise, you can upgrade and pray that Samsung doesn't release something that breaks your rooting capabilities. Check the forums for a ROM based off if the official OTA update and install that. If you have a custom recovery installed, (Which you should have if you rooted correctly) add far as I know, the update won't work.

Hey there thanks for replying Can i find out if i have a custom rom or kernal as i dont know but i did unroot by an app called Ginger Unroot and checked with basic root checker which confirmed that i no longer have root access but the error still comes up. So if an OTA Update is released, then can I download that?
