Re: Accidently set Frequency Range to USA-Band

Hi! I had same problem. Thanks you I could solve it. I was playing with hidden menu *#*#4636#*#* and changed the band at "Phone information" menu -> Select radio band -> USA band . Since then my phone not is registered at network. I could solve it reinstalling phone's software with PC Companion. First, You must a backup of the phone.

Just do a factory reset. Problem solved. No need to connect to PC companion and repair.
