(you can search and download the software from Samsung website and install it to your PC)<BR />*Performed a factory reset on my phone.<BR />*Rebooted the device and the network signal returned.<BR />*Used the Smart Switch app on both my PC and the phone to restore the backed-up data.</P><P>The data restoration only took about 5-8 minutes, followed by another 14 minutes for the phone to download and configure all the apps using wifi (recommended). While I had hoped to solve the issue without wiping the device, the factory reset successfully restored my network connectivity. O, well....
