[Sprint LG G3] 1619415:
IT IS NOT MY FAULT IF YOUR DEVICE(S) BREAK/MAKE A BACKUP IN RECOVERY TO GO BACK TO!

I need some testers to test the guide on ZV8 PM me if you want to test it. You just need to report back to me if it worked or not and what carrier(s) your using this on and what kind of connections your getting.

________________________________________________

ZV4-ZV6

Step 1:

Download "Shortcut master" pro or lite doesn't matter (https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite)

Step 2:

Go into "Shortcut master" and click the little 3 dot (menu) and click "Search..."

Step 3:

Click the little drop down in the upper left corner and select "System apps" (Just to narrow things down ;))

Step 4:

Then on the line labeled "Enter text to search" (search bar/line) and then type "IOT" then click the "Search" button

Step 5:

Click on the option that says "com.lge.SprintHiddenMenu.iot.IotHiddenMenuMain" some options will come up click on the little star that says "Favorite" and then click "Launch" and grant shortcut master su permisson (The star just makes a shortcut on the home screen for quick access)

Step 6:

Click on Network mode and use the drop down menu to scroll down and select "GSM only" If done your signal bar(s) should have a little red "x" over them. (This part does not work on ZV8 but I am working to fix it)

Step 6

Click the back button until you get back to "Shortcut master" then search for "apn"

Step 7:

Click on "com.lge.hiddenmenu.vzw_only.ApnSettings" and "Favorite" then launch it like before

Step 8:

Create a new Apn I wouldn't delete any system one's you may end up not getting data or not being able to send MMS (pictures)

Step 9:

Save your settings and reboot (this way the apn and the radio(s) restart. If you really dont't want to reboot you can go into a terminal emulator and run these commands: su then press the enter key then type killall rild then press enter. This will restart your radio(s) the same thing happens when you reboot.)

Step 10:

Go to settings>roaming>scroll down for GSM settings (Check the GSM box and agree to the pop up)

FIXES-

HiddenMenu force close:

Some say there are problems with the hiddenmenu force closing I recommend that you install this copy of my hiddenmenu that I use View attachment 3054813. Install to system>app>. Also make sure that you have your sprint sim in while you do this then put in your other sim. This is from my stock g3 ROM so I guess (thanks lg for the apk)

It's not working at all:

For some this doesn't work at all I recommend you change your rom to this one it works for me http://xdaforums.com/sprint-lg-g3/development/rom-stock-zv6-base-odex-deodex-t2949087 (Stock ZV6 I'm using the odex version).

Straight Talk fix (>>>maybe<<<):

For some with straight talk wireless they can not get it to work at all. So I was thinking and I was thinking and I figured that you could go into your dialer app and dial the following code (depending on ROM) here it is: ##update# (##878283#) <<< Cheat Cheat. This will reboot your phone and update your network profile/prl and might work or break your phone. Make a back up before doing this! UPDATE*You may want to use the cloudy g3 rom http://xdaforums.com/devd...6315#downloads(make sure to download 1.2) its based of the international rom but may fix your gsm some members say it does. But you still have to follow my guide:)UPDATE*

If after doing this wifi calling or any sprint apps go missing then check out this thread: http://xdaforums.com/sprint-lg-g3/help/fix-missing-wifi-calling-zv4-t2842102

Second Method (Cm12 based)
