you can, via odin or via CWM, you can downgrade to 2.3.6; done it myself (using CWM)
Since you don't mention a specific rom, and having used odin, I assume you have been flashing stock ICS leak.
To revert to gingerbread rom, download and odin-flash the appropriate original rom here: http://forum.xda-developers.com/showthread.php?t=1075278
Important: I don't know if you need to flash the ones with or without bootloader, you need to find out yourself.
This IS NOT ORIGINAL ANDROID DEVELOPMENT.

Ok i'm from mexico city and my carrier is Telcel GSM. I want to debrand my Galaxy SII. Personally i don't like ICS so i want a Gignerbread stock firmware. There are some samsung mobiles that won't work after flash because of the modem. I don't know if this is the case with the Galaxy s2. Hopefully i can flash any firmware and it will work with no problem i don't know. So please guys can you help me out here? What version can i flash to my gs2 so it goes unbranded and stock so i can root later?
Now i'm running 2.3.4
baseband l9100uhkd8
kernel kg6 cfroot
buiild unkg4
Thank you in advance.
is your phone lock or unlock? if you really want GB go with this one
GT-I9100 I9100XXKL1 ## 2.3.6 else go with ics
Hi guys, I'm looking for the stock ICS firmware for my Virgin Galaxy S2 (i9100/m).
Went into the thread with the collaboration of stock firmware but the downloads have been removed for both bell and virgin. Can someone point me to the right direction for the stock rom? Or any rom that's close to stock?
According to my copy of Checkfus, there is no official/stock ICS for I9100M/Bell Canada. If you're after a copy of Gingerbread firmware for this carrier/country, search Samfirmware.com
The last and likely only firmware for Bell/Virgin/Sasktel GT I9100Ms was UGKG2 (2.3.3), if you want ICS you'd be better served by downloading a european stock or custom ICS ROM as Bell has never expressed any interest in doing further updates for this phone.

As I said here, The Galaxy SII for Virgin Mobile in the US is NOT the i9100 or i9100M. It is the SPH-D710, otherwise known as the Epic 4G Touch. anyone looking for stuff for a Virgin Mobile US Galaxy SII is in the wrong forum.

Hi, I was given a Galaxy S2 I9100 with baseband version I9100BOKJ1 T-mobile that has android 2.3.5 installed.
So, I wanted to update it to 4.1.2 through OTA but it says that there are no updates available, what are my options?
Can I just install an official 4.1.2 stock rom through odin? If so, what 4.1.2 stock ROM is compatible with this phone? Thanks!
Yes, you can flash a 4.1.2 stock ROM via Odin. There are plenty of stock ROMs on the internet for our device, most of them are on sammobile.com, but you need to sign in to use it. A simple Google search will show its results. Try to find a ROM matching to your region/carrier.
Think about making a backup of your baseband. There are guides on the internet. If you get big problems with GPS or signal strength with the new ROM, you can flash it back. Some people report the stock baseband solves GPS and signal issues, nevertheless it didn't change anything for me when I tried around switching basebands.
Hope this helps.

Some regions didn't get JB update at all. You can flash your phone using odin.
Go to below link find a none carrier firmware download and flash.

My current rom is xwlsw.
And don't try AOSP stock is always the best.
