Hi guys,
this is my first post , i hope i find some help....
recently i got my samsung galaxy s2 upgraded from gingerbread 2.3.3 to ICS 4.0.3
but since the time i got it upgraded, i am finding some compatibility issues and also internet seems to be not working properly.
Now i want to know how do i revert and get back to my previous gingerbread version..
Any suggestions and help would be appreciated.
Thanks in advance !!
Download your device firmware from sammobile.com

As far I know, you neet to root to flash new ROMs. Once Samsung or your Service Provide have upgraded the version, even if you factory reset, it goes to the same version.
You can take it to a samsung service center and ask them to load 2.3.x. I got this done to my Samsung Galaxy SL. The update published by Samsung to 2.3.7 was very unstable. I asked them to downgrade to 2.3.5. They did !!
No need to root, download the version you want from sammobile or xda and flash it to your GS2 via the Odin program. I did mine yesterday, ics 4.0.3 back to GB 2.3.4 as my galaxy became unstable in ics, wifi issues, SOD and jerky operation. Make sure you find an official release.
Mine is perfect again

Here: www sammobile com/firmware/?page=3&t=1&o=1&m=GT-I9100&r=-1#modelsa (make points between www and com) you can find the firmware you need!
Be sure, which I9100 you got (normal, G,...)
Choose your region and you get the latest GB-Firmware (2.3.5.) flash this with odin and you're lucky

Hey...
I wanted to know about details of available Samsung Galaxy S2 firmwares what changes did each bring?
Mine is XXKF1. When I connect my phone through KIES it says that its the latest one available. Is it really the latest one?
I believe that is your latest firmware available from your carrier.
If you're not patient enough for your carrier to release firmware updates, you can flash updated firmwares by visiting this thread:
http://forum.xda-developers.com/showthread.php?t=1075278
Don't forget to say thanks in his thread if you found his post useful.
If you're feeling a little "adventurous", you can try flashing Custom Roms, that are based on the KH3 firmware (latest leaked firmware right now).
Hope I helped,

As posted above if Kies says its the latest for your phone then it is .

Hi all, I'm new to posting here but a vet over at samdroid.
I've looked around quite a bit and my problem seems to be unique...annoyingly.
I got my S2 on contract from O2 about 4 days ago, instantly went home and found out I was eligible to upgrade to ICS officially via kies. I have been on kies and connected my phone every day since, and I keep getting told I have the latest version (2.3.5), even though I've seen countless threads/comments of people delighted about the fact they upgraded through kies!
I was thinking of trying odin (i was a pro at updating roms on my spica), but don't know if using an offical update through odin instead of kies would void my warranty etc. NOTE: I don't want to actually root my phone (yet)
I hope that all made sense and any help would be much appreciated
Thanks,
Oli

make sure you got i9100 not any other varient
does other O2 in your area got ICS via KIES
odin is fine and will not void warrenty aslong you dont root and flash back the ROM you have now. you have to find this ROM first if you want to go back.

I got my S II on monday from o2 and I beleive its the I9100p not the I9100, if yours has NFC written on the back its the I9100p and for some reason there is no ICS on kies yet for it

what do you mean by this?
also is there an official rom for my particular S2 that can be updated using odin? or even an unofficial one that wont void warranty?
thanks for all the help guys
This Thread has instructions and official ICS.
Plz note that this is official and will have TouchWiz and does look extremely similar to Gingerbread and without root and custom theme you will not get that ICS feel. You will however get most of the goodies that ICS has to offer.
I got my S2 on contract from O2 about 4 days ago, instantly went home and found out I was eligible to upgrade to ICS officially via kies.
Well that's not exactly true you upgrade if their is an upgrade for your exact phone .
Kies has firmware for GT-i9100KAO2U product code .
I have been on kies and connected my phone every day since, and I keep getting told I have the latest version (2.3.5), even though I've seen countless threads/comments of people delighted about the fact they upgraded through kies!
But not for your phones product code which obviously does not match the released O2 firmware .O2 may well and probably over twelve months had more than one phone for sale unless contract has different codes to PAYG .
Standard older O2 UK firmware for xxx Product codes is on Kies its also on this forum in a legitimate flash via Odin .
http://forum.xda-developers.com/showthread.php?t=1544487
legitimate O2 firmware not stock Samsung tested and works on O2 .
Or you can go to Google find CHECKFUS and try to download from your codes .

you still didnt confirm if you have i9100P which i think you have but i could'nt find the Stock ROM your running now, so you can go back to it later if required.
if you have i9100P this thread has good news for you though the actuall thread is stupid and useless...
http://forum.xda-developers.com/showthread.php?p=24030713
i think what happened to u is you got the model which is i9100P not the usuall i9100, thus all on normal model are on ICS and you still on GB. you can wait for it to come or use the i9100 ROM's but please search if that is actually possible.

i read somewhere that i can use i9100 firmwares on my i9100P, so which of those 2 links would you recommend? also, is there a lot of risk or is it pretty easy and you're just covering yourself?
finally, if i update like this, will i be able to update officially through kies when the update is finally released for me?
no im not covering my self...... i tell you in points....
1: you got I9100P on O2 for which i cant find a firmware for.
2: because you cant go back to your old firmware which is O2 you will get into warrenty problems

ok, i guess i'll wait for the official update then. thanks for your help
here are your options if you still want to continue.
1: you can flash stock firmware for i9100.
2: you can flash custom firmware
3: you can flash O2 branded firmware for i9100.
but in all cases NFC wont work by default.
plus now you cant go back to O2 i9100P firmware as it cannot be found anywhere... atleast by me.

Hi everyone,
This is my first time and I am wondering if someone can help. I have tried everything and nothings far.
I have SG SII few weeks ago someone mentioned that ICS was out so I googled it and followed the instructions which installed i9100xxKP8 4.0.3 version and at the first start the phone does not recognise any SIM card you put. I know I made the mistake not noted down the original firmware number etc.. But I am stuck I can't use Kies to upgrade to the proper O2 upgrade which is out.
I had a look at SamMobile.com and I would not see any firmware or instructions.
Any help would be appreciate it before I bin this lovely phone .
Thank you
Wessam
Can you see your imei number?

The O2 UK ICS firmware is on XDA flashable voa Odin not KIES .

No need to bin it if you can boot the phone into download mode. Can you?
And the firmware hasn't "busted my phone" - you did.
Why are you trying to flash some old beta version of ICS into your phone when there are much newer and official versions available such as xxlpq, xwlp7 etc? Just follow the instructions how to flash those firmwares from here: http://forum.xda-developers.com/showthread.php?t=1544487
You can also find the link for Odin at the end of the first post.
Hey guys samsung stated ages ago that all UK unlocked phones can receive the ICS 4.0.3 update through Kies, I seem to be the only one who still cannot update through kies message still says your device cannot update through kies, I have rung samsung support and gave them all my detials numbers firmware numbers eventually they told me that it was my computers fault and that my phone should update normally through kies even though i have told them i have tried on 3 different computers, so im now asking you guys as a last resort to help, before you guys ask i do have the latest version of kies my phone is NOT rooted has stock firmware never been flashed with a third party here is my phones details,

Chris i think you missunderstood my problem, i do not want to install a custom rom or root my phone i was asking here why my phone cant update through kies when my Code XEU is listed as Official ICS Update,
Ignore his root your phone post Updates do not require root as it would void warranty .
Kies updates your firmware when the phone provider has updated it .
You can use CHECKFUS to check on the server and download directly .
Alternative is to flash stock Samsung roms from XDA posted in General and also in stock rom thread .

Try your service provider...
Hi,
I´m in Spain and using Orange. The last time I was able to upgrade my stock ROM, the change came from Orange because they customize it (basically to lock you into using their system). If you choose to stay with a stock ROM, then your service provider may have to supply it and they are a little bit slower than Samsung because they have to add their changes. They usually add quite a bit of "Bloatware" to justify their modifications.
So I rooted my phone and am now using custom ROMs - Resurrection Remix 1.1 and am really glad to be rid of the Orange system. I also unlocked my phone so that I could use SIMs from other countries. Hopefully this will prove helpful....
Hi, quijote1, my phone is unlocked and unbranded so i am not tied with any network in the uk or have any bloatware as far as i know it is a standard rom,
Hey ZacQ8, As i previously stated in my OP my CSC is XEU, witch has been rolled out by samsung through kies that's why i have made this post in the first place.
could my problem be my firmware version? and is flashing with odin my only way now of getting ICS for my phone?
hey guys any idea';s?

You are making an assumption that ICS is available for your actual phone . That may be wrong .
You can use CHECKFUS to actually see if the ICS for your phone is on the Kies server .
Alternatives take the phone to the vendor/Samsung service for an update .
Join XDA Developers forum and flash stock Samsung roms on the day they are released .
You have no other routes except to ask Samsung /your phones vendor why you have no update .

Hi there i got my fone 5 days ago and as soon as i got it i checked to see if there was any software updates thru check for updates and there was ics any so i don't understand how urs ent come yet i dent do it thru kies
Sent from my GT-I9100 using XDA
may i know malaysian s2g can update to ics??
still confused myself as XEU is released so ICS should be avalible through my phone and i dont wanna flash samsung roms myself just incase i brick/invalid my warrenty, i guess the only way is to take it to a samsung repair shop but dosent that mean i have to pay for the update when others get it for free?, just frustrating, is there anyone here who can sugest the correct ICS rom for the Code XEU?
update: ive found my product code and there is a ICS firmware on checkfus do i download it is it the right one? and if so why dosent kies see my phone as a possible update?

UP to you your choice .
it is it the right one?
Who knows you put the codes in correct then presume so if not its easy to tell once flashed .
and if so why dosent kies see my phone as a possible update?
You need a clairvoyant or try asking Samsung .
Personally in your shoes i would stick with what you have and not bother updating .
Because the next post you make is probably how do i restore to GB .

Well, you could try and flash with Odin the right stock ROM. By saying right i am reffering to this : go to settings, about phone and check ur build number. That's the unique code of the stock ROMS, or signatures or w/e you should call them. Those need to match in order to work in India, because you said that its XSA. In my point of view you should flash the Indian Stock ROM just to make sure your out of problems.
If you don't know with Odin browse youtube, or i think you could try with Samsung Kies because the ICS Stock ROM has already been released =D
About backup up apps, well, i used titanium backup and it failed me every time. Use other apps such as Nandroid, Backup Master, Mobile Backup II etc. You said you are not rooted so the titanium works only with rooted phones.
Hope it helps, have fun
Thanks....But as per current 2.3.6 kernel version(KK2) I didn't find matching Indian firmware...only one matched was Australian region ICS kernal(LP8).
I got same firware update thrgh kies...got confused whether to go via kies or ODIN.

if u connect ur phone to KIES and if its showing an ICS update is available then u can give it a try
If you can manage to install your applications again, it's better to wipe before and after the update.
Also personally I don't like backup apps to go from GB to ics.
you can use the following to backup your apps & sms
Titanium Backup for backing up your apps
SMS backup & restore for backing up your sms
You can merge your contacts with google.. or you can export all your contacts to the external card (if you have any)..
You can flash the indian ICS version directly through ODIN. It's very simple, easy & clean.. KIES take a hell lot of time to update.. (that's y i HATE it)
or if you dont want to do that.. you can find an Indian GB firmware 2.3.6 Flash it.. through ODIN & than flash Indian ICS.. using ODIN..
You can download the same from many sites one most popular being www.sammobile.com or www.theandroidsoul.com
If you want to know how to flash using ODIN... you can visit - http://www.theandroidsoul.com/i9100...-update-for-i9100g-galaxy-s2-finally-arrives/
NOTE: The above link is just for your reference if you want to flash your ROM through ODIN.. The direct download link for ICS provided on that page is for "I9100G".. SO I AM NOT SURE WHETHER IT WILL WORK ON OUR INDIAN I9100 model.. You can download the I9100 Indian ICS Firmware from sammobile.com & use the above link to see the steps on how to flash it using ODIN.
Hurray ...! I upgraded to ICS 4.0.3 through OTA Yesterday
No Issues ...No Conflicts , downloaded Installer Package in 30 mins and Installation took 10 mins.
Installer optimized my apps ... All apps are working fine ...... NO need to wipe the data(factory Reset)
If u got ICS update via OTA for your Galaxy SII, then it is the best & simplest way to update your device...
