Here we go guys, latest official UK firmware
1. Just put extract the .tar file in the zip archive and put it as the PDA in odin and reboot your phone to download mode.
2. DO NOT PUT .PIT FILE AND DO NOT, I REPEAT DO NOT, TICK REPARTITION.
3. Connect the USB cable and flash
Anyone ask about .pit file is a moron
I know it's an old screenshot but still the same methodology
No password needed.
It will not wipe your phone if you flash as recommended
You will lose root so just reroot

I used XWKDD insecure to root and this one to flash back the original kernel
Tested on my SGSII with the latest official ROM
