[Q] Moving from branded rom to stock rom - Galaxy S II Q&A, Help & Troubleshooting

I want move from my branded vodafone rom to the latest stock rom. so am I correct in assuming all I have to do is get the latest stock rom from one of the other threads and flash using odin?
Is there anything else I should look out for?

You'll have to reset the phone after flashing, if you want to change the phone's csc

Pick a rom with CSC for your area is the best method .

[Q] How to revert back to a stock phone/backup the stock state?

I have a few questions about this phone. All the Kernel/CSC stuff is kindof confusing for me coming from wm6.5.
1) If I want to have root access, I have to flash a insecure kernel etc. I understand that so far. To revert back to the state without root I just need to reflash the original kernel as far as I understood.
So my questions is do different regions (ATO, AUT, XEU etc.) have different kernels, or are those kernels the same everywhere?
If yes, where do I find a kernel for ATO (Austria), or is there a (easy) way to extract/backup the kernel?
2) In the wm6.5 world we had something called ROM which containt almost everything. I just read that there are also ROMs for SGS2. If flashed do ROMs update PDA, CSC and PHONE all at once? Where to find that for ATO?
Is the kernel part of a rom?
3) Does flashing a kernel change the CSC in any way?
In general I would like to stay on the stock way for updating etc. but I would also like to gain root access.
Something that's also very important for me is the possibility to get back to a stock phone(no root). (I have some dead pixel issue and I'd like to exchange my phone as soon at my carrier has newones in stock)
I am sorry if something similar has already been asked. If so, I simply didnt find it, sorry.
Hey im still quite new to evreything myself but i thought id have a go at answering your question
1. The different regions dont have different kernals but the different firmwares do, so firmwear XWKE1 has a different kernal to XWKE2 but they share the same CSC XEUKD1.
2. The kernal can be part of the ROM and these are packaged as .tar files which will contain everything that is needed to flash all elements of the phone including kernal and csc. the stock .tars will have secure kernals in them that is why people have made inscure kernals so we can use just the kernal in ODIN root then flash back to the secure kernal to keep the root and have a secure kernal.
A for finding an ATO one i couldnt spot a CSC for austria but your ROM/Kernal can be found over in Intratech's thread in the dev section here:
http://forum.xda-developers.com/showthread.php?t=1075278
3. Flashing the kernal doesnt effect the csc that i can tell, but flashing a custom ROM such as villanROM did, i had to flash the csc for my country to get it to show again
tbh Intratechs thread would be a good read for you as it tells you how to root as well as having a good collection of the stock roms and csc.
hope that was some help, hope people correct me if i am wrong
Thank you for your answers.
Another question:
firmware == ROM == CSC + PHONE + PDA?
I am sure there has to be a way to extract/backup the as is state of my phone. If not, where do all the files come from?
Why arent there any ATO's anyway?
This is the state Ihave right now:
Firmware info
PDA:I9100XWKE2
PHONE: I9100XXKDJ
CSC: I9100ATOKD1
Build date: 06/05/2011
My fear is: Since there are no ATO CSC so download, will I be able to revert back to stock after I messed something up.
yeah a ROM is CSC + PHONE + PDA
I think there is a way to do this via ODIN but i havent done this myself.
i guess you just need to find the CSC for your phone and you will be good to go. Im sure there is someone on here that can help you find it
EDIT:
over at http://www.samfirmware.com/ there is a link to download:
I9100XXKE2
MULTI - CSC - ATOKD1
maybe give that a look. i think that will probably come as a stock ROM so flashing that would take you back to how your phone was if it just came out the box, ie. no root.
that being said too root you have to flash an insucre kernal which would add to the internal custom binary flash counter, more info here
http://forum.xda-developers.com/showthread.php?t=1068522
so if you are planning on returning this phone due to its dead plixal then i would maybe hold off the rooting
Thank you.
I think this answered my questions so far.
Is there a way for me to backup my default custom rom?
I can't find it for download and I want to have a backup for warraty reasons.
Here is the info:
Country: Portugal
Operator: TMN
Product Code: GT-I9100LKATMN
HIDSWVER: I9100XWKEB/I9100TMNKE2/I9100XXKE6/I9100XWKEB

[Q] Can you change your Kernel???

Hello All,
I just changed from having a sony xperia x10 to getting a new SG2 and I am brand new to the SG2 forums. I am currently with Rogers wireless in Canada, but the phone was originally a Bell Mobility phone that was unlocked. I do see that superuser is installed on the phone (in which I assume that would be it has already been rooted) and I am able to use the phone on Rogers now.
I now want to install custom ROMs, but I do see that it is quite different than what I am used to. I see that custom kernels are all based on your existing Kernel (please forgive me if that is incorrect...), and that custom ROMS are tailored to specific kernels.
My current Kernel is
2.6.35.7-I9100XWKDD-CL161513
root(at)DELL103 #2
Model number - GT-i9100M
Android version - 2.3.3
Baseband Version - I9100MUGKF6
Am I able to change the kernel, so that I can install custom ROMs onto my phone? Or will the current firmware suffice? Thank you very much for your help, it is much appreciated!
Do you mean a kernel the full firmware or a custom rom .
kernel is upgraded with a later firmware or a custom rom .latest custom rom will usually have latest kernel or custom kernel .
Decide what custom rom you want and follow the instructions .
Rough draft to update to cognition rom latest i would
Flash a matching stock rom KG6 via Odin .
Flash matching CWM and Root Kernel KG6 .
Boot phone and set up .
Follow instructions in rom post which is usually copy to sd card boot to recovery mode and install zip via CWM .
Your Firmware is KDD thats very old now .
Only must check is Bell Canada and do you need to flash a different modem and or CSC for that area .

That is a TON of help. Thank you so much, I really appreciate it
Does anyone know if the current Bell SG2 can install an EU ROM?
Yes, I've installed a custom ROM (lightening ROM) which is based off a European ROM on my Bell's SGS II.

[Q] Problem upgrading from KI4 2.3.4 to KI3 Android 2.3.5

Hi,
I am currently using KI4 Android 2.3.4 and I want to upgrade to KI3 2.3.5.
I downloaded the firmware (but I think it was simply the stock kernel) from Intratech's post - "XXKI3 stock" and I flashed it using Odin, but it got me into a boot loop and thankfully I did a back up before in CWM4, but I had to re-install KI4, root it, go back into CWM4 to restore the phone. Again thankfully that worked otherwise I would have lost everything.
So... how should I be doing the firmware upgrade?
Also, should I download ZSKI3 instead of XXKI3? I know XX belongs to Europe, but where does ZS belong to? Does it even matter where it belongs to?
Lastly, if I decide not to use CyanogenMod, and I want to use another ROM or if I want to just simply use the stock version that came with the phone, what should I do?
Follow the instructions . Stock firmware thread .
http://forum.xda-developers.com/showthread.php?t=1075278
FULL FIRMWARE NOT KERNEL
ZS = China HK firmware .
Lastly, if I decide not to use CyanogenMod, and I want to use another ROM or if I want to just simply use the stock version that came with the phone, what should I do?
Dont make sense to me but if you want to use a rom you follow the given instructions likewise a stock rom read and follow the instructions .

Thanks JJe!
I have another simple question, is there any problem with installing ROM on different firmwares? Because as I look in the forum, I have seen the ROMs having based on KI4, KI3 and so on... is it critical that I upgrade the firmware, then install the ROM?

No mostly is the answer rom modem kernel interchangeable in practice .
My preference if KI3 custom rom would be to install KI3 stock beforehand .

[Q] upgrade to different stock firmware

need some help over here
Phone Info:
PDA:I9100UHKI2
PHONE:I9100UHKI1
CSC:I9100TPAKI2
GINGERBREAD 2.3.4 AND LAST SIYAH KERNEL
i want to stay on stock firmwares, but i want jkay mod.
last version is 13.2 for xwkk5 (2.3.6)
can i update to the XWKK5 from frankestein? (2.3.6)
and then flash my csc from the original stock firmware to have my apn setting or enter them manually.
maybe that is not possible and will brick the phone, so let me know if i can, with custom rom i have made it but i haven´t found one i like and i think is not the same for stock roms.
So i will stay on stock and i want to know if is possible to get to the last gingerbread firmware from mine stock rom!
I would do a full wipe including both cache through recovery mode and then flash away!

Yes you can flash a separate CSC or copy and replace the CSC files on the phone or rom .
Thats for stock or custom roms .
So i will stay on stock and i want to know if is possible to get to the last gingerbread firmware from mine stock rom
If its been released for your product code its on Kies .
Or via the stock rom thread .

[Q] going back to stock rom from Omega and Siyah Kernel,what do you suggest?

Hello!
I want to restore my S3 I9300 back to the stock rom.
this is what I get from *#1234#
AP :I9300ZSEMA1
CP :I9300XXELLA
CSC :I9300PHEEMA1
First,which OFFICIAL ROM are you suggesting to use? I live in Greece and the phone is not branded.Also,since I am using the SIYAH kernel I supoose I have to restore this too to the official Kernel,right? Please suggest me the correct kernel I have to get.
thank you in advance!
Techno.
Q&A is right there for you
Go to samobile a and get latest stock unbranded Rom for your region
Run triangle away
Flash stock Rom
Go into recovery and factory reset
This will put you back to factory/as new condition, note it will wipe your sd card.
The stock Rom includes kernel
