I've updated the 's4 of a friend with odin to 4.4.2 I9505XXUFNB8. Before he had the 4.3 then we installed the cyanogen CM11 on the 4.3 without updating modem or another. Today I flashed the stock 4.4.2 I9505XXUFNB8 with odin but the WiFi does not go does not work. I did the factory reset from recovery after updating but nothing. How do I resolve?
