Guys, I need some help regarding my Samsung S4, GT-I9505, the problem starts after a technician managed to sim unlocked my unit using unlocked gadget "blue box"?? (I'm not sure), as expected, the sim has been unlocked, but my new problem is the WIFI, it keeps on HALF lit state, meaning, it seems to turning on, and if I will try connecting to a network, the WIFI will crash, and restart stating : "Failed to connect to the network". I already flashed it with MI8 firmware, and the latest leaked MJ3, but no luck, I also flashed it with the WIFI-FIX MI8 BL firmware, but still the problem persist, I BADLY NEED HELP. can anyone help me with this?, or maybe my WIFI is broked?, what to do guys?
THANKS, i need help.
