How To Access Hidden Menu/Turn 4G On-Off

[Gman9831]

For service code go to http://www.whiterabbit.org/android/& where it says MEID/ESN enter your IMEI that you get from settings then about phone then, it's going to give out a 6 digit MSL Code & that is the service code for both of the following
*You can use this app to get the MSL https://play.google.com/store/apps/...xpY2VkbWVkaWEuYW5kcm9pZC5tZWlkY29udmVydGVyIl0.

1. For menu for the network select- Go to dialer and enter ##626* then enter 6 digit code that you got above, then go to network select then network mode and you get this menu PIC:http://db.tt/ckh3xgTV
LTE Only - 4G Data only ----- no call or text
CDMA+LTE/EvDo - 1x,3G,4G ----- call & text
EvDO Only - 3G Data only ----- no call or text
CDMA w/o EvDO - 1x ----- call & text
CDMA/EvDO - 3G ----- call & text

2. There's also another hidden menu ##LGSERVICEMENU or ##5473784236368 the service code is the same 6 digit one from the top

Well some things you may do with the hidden menu are:
-Change Network mode : Turning off LTE may save battery life
Field Tests - Check 4G Spectrum Bandwidth
Semi-booting mode - Enable Semi-Booting mode (http://androidforums.com/motion-4g-all-things-root/661377-interesting-find.html)
Network Lock - Change Network lock mode
ICC Activation Setting - Make it where the phone still works even without the sim card
-Hardware & Software Tests
And more but I don't have this phone so I cant list all of them
^^These arent confirm so if you see it in there just post here that these are in this hidden menu
Thanks to Cubone for confirming the codes for me.
