When I try to update my Gingerbread Galaxy S2 through Kies it says "Your device does not support updates via Kies".
My current firmware version is
I9100XXKL1/I9100OXAKL1/I9100XXKL1/I9100XXKL1(KOR). When I've tried to update from Settings >> Software Update it said "No updates are available".
What should I do to upgrade to ICS 4.0?
