[Q] root - Galaxy S II Q&A, Help & Troubleshooting

I am new to the Android scene (previously I had Iphones) and I recently bought a Galaxy S2.
I am having some problems where my phone is utilizing my data plan without my knowledge.
I have read that one of the culprit aps is Ap Mobile and the only way to remove it is by first rooting the phone.
I have read a lot of treads and it is still confusing with all the different kernels, basebands etc…
I have 2 questions requests:
1- My phone has Model number: GT-I9100, Android version: 2.3.3 (updated by KIES yesterday), Baseband version: I9100XXKG5, Kernel version: 2.6.35.7-I9100JPKH1-CL453266 [email protected]#2, Build number: GINGERBREAD.JPKH1
I would be very grateful if somebody could post clear instructions as to how to root the phone.
2- there are so many different Kernels, and some of them show android version 2.3.4 or 2.3.5. Can I update to the Firmwares\Kernels from my phone, if so, how?
I shall thank in advance anyone who are willing to help me with my questions

this thread is for updating your firmware and rooting
http://forum.xda-developers.com/showthread.php?t=1075278
if you use data for a specific time like me
P.S you can turn off data settings>wireless and network>mobile networks

Please use the Q&A Forum for questions Thanks
Moving to Q&A

I want to have data on all the time because I have my work mail setup.
My data plan is 250 Mb and I only utilize it to access my work mail, it was never an issue on the Iphone, but on the galaxy my data plan was used in a couple of days.

[Q] Rooting the Samsung Galaxy S2 - India Version

Okay guys, First off I apologize if my post is too noobish. Yes I am a noob at all this.
I rooted my phone using steps mentioned here - http://samsunggalaxys2review.org/forum/showthread.php?tid=43
I bought my phone in india with the KE8 update, and now the About Phone section shows the following:
Android Version - 2.3.3
Bsaeband Version - I9100DDKE2
Kernel Version: 2.6.35.7-I9100XWKDD-CL 161513
Build Number: GINGERBREAD.XWKE8.
I read about a post for rooting the galaxy S2 here - http://forum.xda-developers.com/showthread.php?t=1101671
and am a little bit confused. Firstly did I do the rooting with a piece of old software or something? Do I need to do the rooting again or flash my phone with some other latest software ?
Can someone please spoon feed me some info about:
1. Whether I need to infact update my software and flash my phone again
2. If so how?
Thanks a lot guys, and again sorry for being too noobish :S
flash CF-root KE8 kernal as per
http://forum.xda-developers.com/showthread.php?t=1103399
that way you can keep your KE8 and have Root AFAIK
(take no responsibility blah blah blah)
http://forum.xda-developers.com/showthread.php?t=1101671
I found this thread here and here they have given source of the Stock KE8 Kernel. Since i have already rooted my phone, is it enough if I just flash my phone with this stock kernel to have the latest software in my phone?

yes just download the stock kernel KE8 and flash over the rooted one, and your phone will still be rooted
Well I have rooted mine yesterday after a 3 hours effort. I think there should be a thread for Noobs like OP and me which will elaborate the Steps & Methods, the Application needed etc. in a Simple way with good demonstration. Not everybody had Android before, so for the new comers this is hard, very hard to understand all these. Like I am now having difficulties with ADB, I don't even know where to install it and from where, how to use it? The devs are very easy with these stuffs and they just mention the software name, but we, newcomers to Android are getting puzzled. It's a like a 5 year old baby has to face class X straightaway.
Some basic faqs SGS1 mostly same SGS2 .

Thanks mate. Just 1 more question:
Firmware info
PDA:XWKE8
PHONE: DDKE2
CSC:ODDKE2
Build date: 18/05/2011
Generic India (ODD): www(dot)multiupload(dot)com/6OZ2KOHB07
XWKE8 Stock Kernel: www(dot)multiupload(dot)com/ZTRYIQ5S35
There was another thread where I found this. Which here should I use? What is ODD Generic India and what is the difference between this and the Stock Kernel?
And btw here is a guy that explains everything in detail on youtube:
I followed his instructions, and did exactly what he did and rooted my phone in 10 mins

This is the stock kernel which came from the Samsung factory. The phone is NOT rooted if you did not root it. You can do rooting with an insecure kernel and then revert back to the stock kernel, keeping the root intact.

[Q] Holistic understanding of phone.

Hi XDA Devs & Members,
I'm a new member, and I've spent hours scouring over the forum to my answers but I'm still slightly confused.
I'm currently using Galaxy SII, hence the post in this forum under Q&A
Firmware:
Android: 2.3.4
Baseband: XXKH3
Kernel: 2.6.35.7-I9100XWKDD-CL161513 [email protected]#2
Build number: Gingerbread.XXKH3
I originally wanted to debrand the vodafail branding, and flashed the firmware of XXKH3 which is the "Frankenstein version" according to here
Then I messed up my sms by pressing the 'update' button in *#*#4636#*#* phone information menu which is another story, but I fixed that rooting the phone using Odin and SuperOneClick.
So basically, what I want now is to go back to basic, don't use one of those frankenstein firmwares, but a stock one, stay as close to stock as possible, root the phone, I know CF-Root has a made a post on this, but now that I've already rooted my phone using Odin, I don't know how to go back.
Also, I've been searching, but I haven't been able to find a comprehensive guide/information regarding how to understand the phone. I understand the individual parts, i.e. what rooting does, what roms are, what are firmwares, but I'm not able to put them together to give me a holistic understanding of the phone. Is there something I can read to understand this?
Thanks in advance. This is a great forum!
=====Added Questions=====
Also, does the firmware code represent anything? I.e. KE7, KG8 and so on...
How do I find out which is the latest firmware?
Who develops these firmwares?

Thanks JJe!
I have another quick question, does factory reset reverts the phone back to original settings with the folders and everything else the same? I may be paranoid, I executed busybox installer multiple times and the folders look like a mess when I connect the USB to share files. All the additional folders that came with rooting and TitaniumBackup and other apps made the entire phone look like a mess. Is it worth doing a factory reset?
Factory resets reverts to the last firmware installed wiping phone and user apps . Out of the box setup then required .

Rooting the T-Mobile (U.S) Galaxy S2

Hi All,
YES I did do a search (actually several searches)
and YES I did do a bit of reading before deciding to post this.
Things I'd like to accomplish by rooting:
1.) Get rid of T-Mobile junk (and there's a LOT of it!)
2.) Install Arabic support (haven't figured out how to do that yet)
3.) MAYBE overclock (haven't figured out how to do that yet)
I would like to root this T-Mobile (U.S) version of the SG2. However, none of the posts seem to match the kernel number, firmware, or even model number as listed on the phone (see below)!
In order to avoid bricking the phone, I wanted to see if someone has managed to do this, and if s/he can direct me to the correct method/post to do this.
Here's what "About Phone" lists:
----------------------------------------------------------------------------------
Model Number: SGH-T989
Android version: 2.3.5
Baseband version: T989UVKID
Kernel version: 2.6.35.11 (no letters after the number!)
Build number: GINGERBREAD.UVKID
----------------------------------------------------------------------------------
Can someone please help idetify which recovery, kernel, and (if applicable) ROM I should be using?
Thanx

[Q] Absolute Android n00b Question

Hey guys - 2nd post here so please don't flame me!
I've had a read at the wiki's and stuff and some of it kinda seems daunting.
I've just rooted my phone as I was keen on getting the Orange signal boost app working on an unbranded Galaxy S2. Everything went surprisingly well ...not a bricked phone in sight and the app is working!
I have been planning on rooting for a while but now that I have done so, what can I actually do with my rooted handset that I wasnt able to do before, except getting access to the root of my handset?
I apologise in advance as i knw it's a total n00b question - it's my first android handset so i'm keen to get stuck in!

Umm you get tons of features including: flashing custom roms using app called rom manager, which can make your phones preformance better. You also get free wireless hotspot. You can put any carriers sim card in and will still work. You have total access to your device. And you can get apps supported for rooted devices. Hope you find something usefull out of this. Any questions ask me. Thanks

- CWM (Best way to flash ROM's, and make backups)
- Adfree hosts file
- Overclock
- Flash Custom ROM's suck as MIUI or CM7/9
- Sim unlock
- Remove bloatware (from Samsung / Carrier)
- change system files
thanks for the replies. Am i right in thinking that custom themes and custom rom's are the same thing? :S
Custom themes and customs roms aren't the same thing. Themes are high-level changes that don't really do much to the system itself (changing how it looks pretty much) whereas roms usually have many low-level changes and features.
Custom ROMS, themes, apps, overclocking, so on and so forth.
In other words, you get to have an actual bad ass phone without junk and crap that slows the phone down and reduces it's actual performance.

Basically, themes change the UI (and how everything looks), while roms change the entire system.

It seems like you have the European Galaxy SII (also unbranded), so I would recommend these roms: http://forum.xda-developers.com/showthread.php?t=1162715 or this: http://forum.xda-developers.com/showthread.php?t=1312240.

Need experienced help on CM 9 i9100 install

Calaxy S2 i9100 (international)
stock Android version Gingerbread 2.3.5 not rooted
Baseband version: I9100XXKI4
Kernal version: 2.6.35.7-I9100JPKJ2-CL655700 [email protected] #2
Build number Gingerbread.JPKJ2
no carrier. GSM sim card.
I want to perform the following to my i9100 phone:
1) How to move from the official Gingerbread 2.3.5 version to cyanogenMod 9 ROM. Including, can I install Cyanogen 9 on top of 2.3.5 kernal.
2) Best safe way to backup original stock Gingerbread ROM in case something doesn't go according to plan.
3) How and at what point during upgrade to CM 9 to root.
4) Which is the proper, stable kernal for this CM 9 (dorimanx has been recommended). At what point, during the upgrade process, is the kernal changed. This is a main concern I have.
I have never done any of this before. I didn't want to upgrade to Android 4.0.04 because of potential Super Brick or other complications. Jelly Bean is not an option for other reasons.
CyanogenMod 9 would seem to meet all my current needs for this phone, and is open source)
I have not seen a detailed "How to" guide to upgrade from stock Gingerbread 2.3.5 to CycnogenMod 9, rooting, and kernal install. Just parts of it scattered, a year old. Can someone guide me through this.
I just need a flexible stable everyday ICS level phone. I'm open to suggestions. Please remember, I have not done any of this before. Thank you.
Spoon feeding is not aloud here on xda. Please read them scattered threads for the info you need them put it all together and then read abit more. Learning is the key to xda not just asking then getting what you want. First thing you need to look at is rooting. Good guide on here telling you about root
