I received official 4.3 update. frankly i didnt like it just like the jeally bean. call me crazy but i really liked the ICS too much and it was more than i need. i usually downgrade from jellaybean to ICS without any problems. its just last night when i tried to do that from the 4.3 i lost my Imei and it leads to no network thing / lost signal !! i was trying to use my stock room ( latest ICS update ) which is I9300XXBLH1_I9300OJVBLH1_XSG but now after flashing this as i mentioned i cant do calls.
Is there is any way to fix this? i heard that i have to flash the modem and thats all. please help am currently on 4.3 .
thank you soo much guys.
