Base Version : I9100GDKJ2
Kernel Version 2.6.35.7-g7b57e17-dirty-Lucifr_1.60uv-200Mhz

Flash your stock 2.3.6 xwlc2 stock rom simply via odin. Or if u want a faster method, just go to privacy and hit factory reset. It will be as good as new. Backup your data before doing it though as you will loose data.
Thank if i helped mate. Hf

you don't need to wait it for that much of time.. as odin says pass after 5 minutes...
when all steps are completed and phones reboot to apply CSC update and then reboot to samsung bootanimation you can take off phone and wipe it through recovery to get it working..
waiting for odin to say pass == wasting time

If you flash the siyah kernel before you start that gives you the option to boot into download mode after you've finished the wipes and formatting. You can pick any region of firmware I can't answer about the carrier as I always opt for the unbranded version as there is less bloatware on it.

How to get Official JB Update (when it's out)

Hello
I just wanted to ask a question about the official jb update from Samsung.
I'm currently running a custom Omega ROM, if I want to change to the official Samsung JB, when it comes out, how would I proceed best?
I tried to find out how to revert to Stock, so I could just do an OTA update, but I don't have an original Stock Firmware Nandroid Backup..
I live in Switzerland and had a Swisscom branded Phone, which was not locked.
What do you think?
**EDIT**
or the leaked JB test firmware
You can find your firmware at sammobile.com. Just flash it with odin.

If from OMEGA rom , do you want to go to a rom stock samsung , run before a nandroid backup and save the folder EFS , performs a wipe date , factory reset ,then after with ODIN flash rom stock samsung , if remains in boot-loop repeat a full wipe from the recovery ....
I would wipe phone and install JB as its a new OS not an update .
jje
there's still something i don't get..
i do still have the ota option on omega.. is the firmware seperate, which would mean that i would be possible to be on omega rom and have a stock firmware, or do i also return to stock rom when flashing the firmware?

No, because Omega is a costum rom,it's based on a stock firmware and kernel but, it's a modded firmware so you must wipe everything and flash with Odin if you want to go back to a Samsung Stock firmware.

[Q] Galaxy S2 i9100 Official Android 4.1.2 Firmware

Does any one have the download link for Android 4.1.2 Jelly Bean (i9100) Samsung Official Firmware? I flashed a custom rom to my Galaxy s2 without creating a firmware backup so I cannot revert or downgrade to original rom. So I was wondering if I could download official 4.1.2 firmware then I can flash it. One more thing pls: A friend of mine own a galaxy s2 i9100 and it has the same version of firmware that I am looking for, so can I make a backup of its firmware and flash it to my s2 or copy its firmware as a zip file or something.

Sammobile is all you need looking for your apropiate carrier of course.
Samobile requires premium account

No it does not. You only have to register, for free, in order to DL firmwares. Nothing premium required. Stop spreading nonsense.
Also, next parrot who posts 'Go to Samfirmware' to this thread dies. Once was enough, 3 times is ridiculous. What the hell is wrong with you people ?
I thought it was premium ..
Thank u man
