Root and Upgrade I9100 - Galaxy S II Q&A, Help & Troubleshooting

Hi All,
Below is my phone details:
Model Number - GT-I9100
Android version - 2.3.3
Baseband - I9100DDKE4
Kernel - [email protected]#2
Build - Gingbread.XWKF3
I want to root my phone & flash ICS custom ROM.
The problem is "LOTS OF INFO" which is confusing me & also not "Much Info" on "I9100XWKF3" kernel.
I want to use "Semaphore Kernel".
Please guide me on how to do this.
Regards
Sudhir

You need to sort that info, look for recent posts.
If you have any doubts, post them in THOSE threads.

[Q] Which kernel do i have? Samsung Galaxy s2

Hi,
I watched the noob video when registering, heard that you should ask in the thread relating to your issue, well i wasn't allowed as a noob to post in that thread because i had below 10 posts, which makes the video telling me to do that stupid.
Anyway, i wanted to root my Samsung Galaxy S2 ( this thread: http://forum.xda-developers.com/showthread.php?t=1103399 )
But i don't understand which kernel to download for my phone cause non of them match my kernel when i look in my phone.
This is the kernel my phone has : [email protected] #2
Which kernel root package do i need to download? Is this KE2, KE7, KE8 or KF1??
I have no idea, i'm very confused.
(Reason i want to root is to mount smb shares with cifsmanager, and only that.)
I'm realizing my version is XWKDG which no one else on the entire internet has, this is probably because i turned in my phone for repair just after 2 days after recieving it due to some technical errors, i'm guessing they gave me some firmware no one else has?
Can i just use the KE2 and root with that or the XWKDD? Honestly, try google XWKDG and you'll find nothing. Everyone who is aksing about it is me, it feels lonely.
Check your link again, there is a Kernel that matches your slightly, the: XWKDG1
Hi, Im noob and I have similar problem.
I have bought 8 days old, second hand galaxy s 2 that is rooted and I want to unroot it. Problem is I dont know which cf root to use (there are 3 diferent codes XXKE7, XWKDD, XWKF3). And also which is the stock/original ROM???
Here is the info
Baseband: I9100XXKE7
Kernel ver: 2.6.35.7-I9100XWKDD-CL161513 [email protected] 103 #2
Build num:Gingerbread.XWKF3
Thanx
u should look I9100 in ur kernel ver so urs is XWKDD
Thank you, thank you, thank you...
I am still trying to find the thank you button...
Can someone explain more about kernel? What will happen if I flash a Rom with different Kernel than the one on my phone?
Also Can i flash a different kernel, or i should only look for ROMS that have my kernel only.
I have been looking for weeks over the forum but i couldn't find a helpful explainaition for Kernels.
Thank you. i know there are many experts on this forum that can help us.
I need a hand as well please. I am new to all of this but I have read quite a bit so far on rooting my GS2. The issue I am having is that my when I go to
settings > about phone > kernel version it only reads 2.6.35.7 There is nothing after that to denote which CF-root I need to be using. Any suggestions would be appreciated.
Model Number : SAMSUNG-SGH_I777
Andriod Version : 2.3.6
Baseband Version : I777UCKK6
Kernel Version : 2.6.35.7
Build Number : GINGERBREAD.UCKK6

Meatness: I had the same issue. If you install "cpu spy" (find it on the Market), it gives you more information about your CPU, including the full kernel information.
Hope that helps!

[Q] Samsung Galaxy S2 I9100T Kernal and NAND Question

Hey kids,
Some details on the phone:
Samsung Galaxy S2 I9000T
Android 2.3.3
Baseband Version: I9100TDUKF4
Kernel Version: 2.6.35.70I9100XWKDD-CL1611513 / [email protected] #2
Build Number: GINGERBREAD.DUKH1
So I'm new around here, I've done some searching and I've read as many of the pertinent pages of this huge post as I could, it's quite long hehe, but I still have some questions. So if someone in the know can help me be in the know, that would be ace:
1) I found a guide on the net, which had a modified kernel attached to grant SU. So I followed that guide, and all went well and now my phone boots up, yellow warning triangle and all, and I have SU. However if I try to remove or freeze some system apps (not all), I'm told there is an error and that I need "NAND unlocked". What is that/does it mean?
2) In the post I linked above, there are numerous attachments of modified kernels. Now my understanding from reading it, and other guides, is that I should try and match the modified kernel to my current kernel version as close as possible. Since I've already updated it with a new kernel, I actually cannot recall what the existing number was and there is no kernel close to my one ( 2.6.35.70I9100XWKDD-CL1611513). So does this mean I should rather not try a new kernel, or, how do I determine the correct version to use (I'm not understanding the differences)?
Anyway, thanks for any help!
Cheers!

[Q] Where do i find an insecure Kernel for 4.0.3

Hey everyone,
so i've rooted my phone once before, and after some time i decided it was time to install chainfire's rom due to my battery drainage.
so i went on over to chainfire's thread and read... and read.... and read... downloaded all the jizz. and eventually i got down to the odin part. it was hanging at a specific step. anyways i read... again and realised that my firmware supported a very old recovery tool that didnt work so great. so i got back down to the site and read some more, and eventually got down to installing a new firmware (still confused with firmware vs kernel... but anyway)...
i went down to sammobile. and voila got a 4.0.3 firmware nice! but then... root was gone, and like my rooted apps that installed requested it needs to be rooted first. so i was like (EFFFFFF) anyway.
so i began searching again on how to root, and yes i know i need an insecure kernel... but where on earth do i find this thing.
i noticed that on sammobile they have kernels (or is it firmware, jeez all these names )... and i noticed that some of them have hash signs (##) next to them, does that mean it's insecure? i read somewhere that the star (*) sign means incomplete (it's an update rather)...
so please, someone, anyone, please help...
all i wanna do is install chainfire's rom

thanks in advance guys...
Just download and flash via odin the cf root kernel for LPQ which is compatible with LP7 (use the latest version 5.4 referred to as proper it is a bug fix version). This will give you root and cwm.

You'd probably be slaughtered alive for posting this question. This is xda, mate. Search, read and try before posting questions. And even if you do have to post a question, find the correct thread for doing so.
Since you asked, look through this thread for all your rooting requirements. Me and probably a million others like you have read that and then managed to root their phones following the steps mentioned there.
http://forum.xda-developers.com/showthread.php?t=1103399
Dont forget to thank the contributor.
Yours being 4.0.4 theres a problem with an EMMC bug bricking the phone. again, read the forums thoroughly before going ahead.
Just flash a pre-rooted kernel.
I guess there is a thread discussing about rooting.

***** PLEASE read this important information*****
-You are running stock 4.0.4 ROM which it's known to have brick bug on it's kernel.
-after rooting, DO NOT factory reset/data or restore any backup without changing your kernel to custom one. Siyah, Dorimanx, Dream, and Speedmod kernels are known to be safe.
-You must change your kernel after rooting. It's better to be safe than sorry

Swyped from my Samsung Galaxy SII
I have the same setup as you so I think you can look into my thread which i started yesterday and Jokesy took the time and answered all my questions there including linking to a guide (thank you Jokesy, fantastic). I did not use Odin, but i used CWM Recovery Touch.
After following Jokesy link i rooted my phone, i installed the latest siyah S2 kernel (no beta), i also installed Titanium backup and purchased the PRO key. After that i followed an external link of services and programs that i could safely freeze/delete.
It shall be said that i have been using SGS2 since last spring/summer and this was my first time modifying anything with the phone.
Here is my thread: http://forum.xda-developers.com/showthread.php?t=1841641

For simplest root just use method 1 from 1st guide in my signature. No CF-Root, no CWM needed. Just copy one file to external SD card and update from stock recovery.
- Thanks for the contributions... - there's a lot to take in -
- This 'Bricking Bug' is something of a concern... - so I'll be doing some more reading before I choose whether to proceed with rooting my SGS2 -
- Hopefully things will be simpler with the Nexus 7... -
- Understanding the various versions, terminology & methods etc. is giving me something of a head-ache today -
- But thanks again... -

different basband?
Hello devs,
I ran into a problem few hours ago and I am trying to work my way around and through it. I honestly did, I have already lost patience and feel like quitting life itself. I wiped my phone, installed a different BOOTLOADER, different MODEM, different CODE and different CSC. I did all this to install a new ROM, I didn't like the changes so I went for my backup and restored it. Everything was successful, except that the Baseband version hasn't changed at all.
What is a baseband? Does it matter if I installed a different one (it is supposed to be XXLPS-I9100)?
Thanks
Baseband and modem are pretty much the same thing mate. You don't need to have a particular one. If you find your signal isn't as good as it should/used to be, you can change your baseband at a later stage. It doesn't matter if you stick to the one you have. It won't spring up at night and chop your phone into two bits

Hey i have a problem my samsung galaxy s2 is an indian version 4.0.4 and its baseband version is I9100 DDLPB so its ok to root it with another baseband verison?

[Q] Kernel for my GS2

Hello,
I have a S2 that don't accept the official firmwares, it's a i9100. I have had the same problem with a GN N7000 that I solved by installing a Rom Custom (but i have battery issues...)
Could you help me by chosing a Kernel, there is so much I don't know which to choose.
For exemple, I would like to install a CyanogenMod 10.2 (JB4.3), shall I use this CWM : GT-I9100_JB_ClockworkMod-Recovery_6.0.2.7.tar ?
or this KernelSafe : CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5.zip ?
My phone :
Anroid version 2.3.3
Baseband version I9100XXKDJ
Kernel : 2.6.35.7-I9100XWKDF-CL170898
[email protected] #2
Build Number GINGERBREAD.XKDF
The mobile is rooted
Many thanks.
I strongly suggest you read the guides/tutorials stickied near the top of the General section before you do anything with your phone
