[GUIDE] HOW TO GET NETWORK MODE SWITCH (WCDMA Only, GSM Only) on 4.4.2 NC5/NC2
Hi, I hope that this will be useful for those who upgraded to 4.4.2 like me and were looking for hidden menu (at least) to change from GSM network mode to WCDMA mode and so (Testing mode is shown as disabled/unavailable on NC2 and NC5 when you use any application like Pimp My Rom or Hidden Menu App to access to Hidden Menu)

After doing this reboot your device, then go to Settings > More Settings > Mobile Networks > Network Mode and you will get a screen like the following screenshots:
