resetting 4G/3G toggle for Thunderbolt

[karend1840]

Hi, New to Android. Concerned about battery life on Thunderbolt. Entered test mode w *#*#4636*#* and happily changed to 3G only. Reset phone. Now status bar does not show 3G. And I cannot reenter test mode - the entry just sits there in the phone keyboard. Help appreciated.

You might need to do a factory data reset to restore that value. Check out our HTC Thunderbolt forum for further assistance...
