I flashed my i9103(Galaxy R) from 2.3.4 to 4.0.4 Stock India via Odin, and after that my serial number has become 000000000 and the phone cant find the network!
I tried flash another 4.0.4 stock rom, but nothing has changed. IMEI is OK, ONLY with serial number problem
Sory for my bad english
I will be very glad for advice! Thank you!
P.S. I created question in this thread, because in Galaxy R original thread too quiet, i hope this is not big problem
