Hi I have a Samsung Galaxy SII GT I9100 2.3.5 it I9100XXXK13, and Kernel 2.6.35 7-I9100XXK13-VL577579 #2 and has gingerbread.XXK13. It is unrooted. They send it to me from Luxembourg and I live in Greece. Greek samsung and Greek Kies Is updating Jelly bean.4.1.2 but when I connect the mobile it syncronizes it takes a back up but says it there is no firmware update. No techcnisian takes the responsibility because is from another country. I want a sure solution beacause I am psychologist and I have a lot of apps for psychology and psychiatry and some of them paid and for sure I dont want my mobile to lock ,
If you know a sure way to update to Jelly bean 4.1.2 I would appreciated a lot ! And please I really need instruction not just words odin, OTA , because its from another planet for me !
thank you very much
