Do this
Config>More Settings>Mobile networks.
In network mode select WCDMA Only for 3G and GSM Only for 2g.
Note: If you are using both sim cards only one sim can be set to WCDMA Only Mode.

[Need help] Radio off, can't turn it on

Here are the symptoms:
When going into the network settings and pressing choose a network operator, it says "Error while searching for network"
If I select "choose network automatically", it says "registered on network" but nothing changes.
When I tried to make an emergency call, for example, it tells me to turn off Airplane mode. However, if I scroll down the notification bar, Airplane mode is OFF.
In About Phone> SIM Status>:
Network - Unknown
Network type - Unknown
Service state - Radio Off
Signal Strength - 0dBm 99asu
Network State - Disconnected.
IMEI IS THERE. NOT CORRUPT.
Dialing *#*#4636#*#*
Will not let me change preferred network type.
Pressing Turn On Radio does nothing.
Neither does updating smsc.
I did what anyone with common sense and a little research would do.
Reboot phone
Remove/insert sim
Tried my dad's sim, which is on a different carrier.
Tried slot 2 as well
Wiped cache partition
Then as a last resort, full hard reset. I have wiped dalvik, system, data, user data and cache.
...But to no avail.
Restore qcn from other device still not fix error
