Downgrade i9100MUGLD3 from ICS to Gingerbread - Galaxy S II Q&A, Help & Troubleshooting

Ok, i have seen a lot of threads looking at downgrading, but i cant find anything specific to my version of my phone. I am on the Sasktel network. I have seen lots of stuff about downgrading, but none have the same specs as my phone.
PDA: I9100MUGLD3
PHONE: I9100MUGLD3
CSC: I9100MBMCLD3
Any help is appreciated. I rooted it before, then upgraded to ics, then had to flash with ics again due to a booting problem, which made me loose my root access. All i want to do is get it back to the stock Gingerbread 2.3.3 it came with.

Need...Some help with Flashing

Hi, I have looked endlessly to try to get a grasp on the concept of flashing but it seems to refuse to sink in for me, so I'm hoping maybe one of you more experienced in doing this can help me out. First off, I'm with Bell and my phone information (Still on stock) is as follows.
PDA: I9100MUGKG2
PHONE: I9100MUGKG2
CSC: I9100MBMCKG2
Basically, what I want to do is upgrade the firmware to 2.3.6, but preferably I would still like it to be an 'official' upgrade and from what I've read, it seems that it must NOT be a 'Frankenstein' firmware.
Then I'm only left with the...:
XILA2
Firmware info
PDA:XILA2
PHONE: XWKI1
Date: 12/01/2012
Android 2.3.6

Is it safe for me to install this firmware even though I have a different phone model number and everything? Every guide I've looked at just says to pick ANY firmware from http://forum.xda-developers.com/showthread.php?t=1075278 so I don't know if that's true or not. If I installed this firmware would it change my CSC so that my phone would no longer work with my Bell carrier?
Thanks in advance...!
TLDR: Can I use this firmware update with my phone and would I still be able to use my phone with my current, Bell, carrier.
If you would like to help me, I would greatly appreciate it if you could use some links (preferably download links) in your response. Even if you don't want to help me, thanks for looking anyways!
i am also curious
Edit: Answer was given here: http://forum.xda-developers.com/showthread.php?t=1453251
No, if you are on a carrier locked device then you must flash carrier specific stock firmware in order to save warranty otherwise its fine to flash pretty much anything
BTW you should have received official updates by now.
If you can elaborate more about your location then we can help you out.
Alternately you can also check out this thread, it its for Bell/Virgin Canada Specific devices

[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.

RE
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?

[Q] Roll back to Gingerbread on O2 (UK) GSII help

Phone specs:
Model: GT-I9100
Android Version: 4.0.3
Baseband Version: I9100XXLPR
Kernel Version: 3.0.15-I9100XWLP3-CL287862
[email protected]#3
Build Number: IML74K.XWLP3
Operator: O2 (UK)
I have the above model and since upgrading to ICS, the phone has an issue where the battery seems to drain within a couple of hours. I have done a factory reset, run with no additional apps, and even bought a new battery. Nothing has helped. Upon my google travels, I saw a number of users with similar issues who were blaming ICS. So I would like to roll back to Gingerbread.
I found this guide: http://www.galaxys2forums.com/17-sa.../3405-how-roll-back-gingerbread-gt-i9100.html which tells me to download the O2 UK firmware from here: http://forum.xda-developers.com/showthread.php?t=1113928
I think I need this one: XWLP3: Download - Firmware info: PDA: XWLP3| Phone: XXLPR CSC: eek:2ULP4
But the link seems to be dead. Is there anywhere else to get the firmware? And am I looking at the right thing in the first place?
Sorry if this is a very basic query, but I have no experience with flashing phone firmware and would really appreciate guidance on this as my phone is almost useless to me right now.
Thank you!
Sammobile......and you dont know the difference between gb and ics obviously

Thank you for that link. I am now downloading the firmware.
"United Kingdom (O2) 2011 November 2.3.5 I9100XWKJ1 I9100O2UKJ1"
Apologies for my ignorance..The tutorial I linked to then linked to that thread which made me think that all the links there were for GB firmwares. I don't know how to read the shorthand for the different Android versions.
Its ok.Just google firmwares next time to see which version it is.
I run rooted kg5 on this thing.

[Q] Attempted to unbrick after rooting and failed, help?

About a month back maybe two I attempted to root by S2 using several guides on this site. I managed to **** it up and brick the phone, shortly after I managed to unbrick it and flash back what i thought was the correct stock firmware.
At first I noticed several small differences in the OS, the contacts list didn't show up in the phone app. As well as these small differences I also have been experiencing an issue where the phone would just turn off and the only fix would be to remove the battery and reboot.
I have no idea how to go about finding and putting back the correct firmware on to my S2. I looked at several sites that host the many many stock firmwares but was afraid to try incase it screwed up the phone even more. I tried connecting it to Samsungs Kies but that informed me that a factory restore was not compatible with my phone.
I don't really care about having a rooted phone anymore, I just want to get back to the stock firmware with my phone fully working again.

Unless you had to perform JTAG connection or replace motherboard your device was not "bricked". Its likely you simply flashed incorrect kernel/rom resulting it device not booting to system.

Take your pick. As long as it's 4.0.3 you are all good.

For my unlocked S2 which has a EE/T-Mobile sim, I'll be fine?
I've tried the 4.0.3 T-Mobile and 3 4.0.3 and both have errors once installed.
I can't seem to find an unbranned UK 4.0.3 which is what mine was originally I think.
tried looking over here?
If you want unbranded go to sammobile.
