Now you can open 'Secret Code Explorer

I still can't get this to work on my Verizon S5 (SM-G900V - v4.4.2 - G900VVRU1ANCG). I can get into this menu but I dont know where to navigate to open that dialog. I have tried manually searching for that shortcut "Servicemode" and "service mode" and none of those open that dialog.

I found it but now there is another problem.
If you look for code 2263 and use root privileges (method 0) to open it you get the menu. Options are as follows:
1 - Automatic
2 - WCDMA Band Preference
3 - GSM Band Preference
4 - LTE Band Preference
5 - WCDMA/GSM Mode Only
6 - LTE/WCDMA Mode Only
7 - LTE/GSM Mode Only
If I choose anything other than an LTE mode, I get an icon (where the reception icon is) with a circle with a forward slash in it (meaning no service). Perhaps there is something more to set the Verizon S5 in CDMA only mode? I know on my Motorola Razr Maxx HD there was an option to CDMA auto (PRL). Perhaps it doesn't have the Preferred Roaming List (PRL)? I have run the *228 but it gives me a message: Sim Card: A Version Wireless SIM card has been activated your service and updated your phone's roaming capabilities ...
