Or restart with a Sprint SIM card inserted, select network, then replace with user SIM.

To enable diag/hidden menu:
GSM

3845*#<model#># (diag)
159753#*<model#># (diag)
*#546368#*<model#># (diag)
*#865625# (unlock)

Verizon

Sprint

##3424# + SPC code
##8378# + SPC code


You can try to following ADB activities (not all will work, but worth a try):
adb shell am start com.lge.SprintHiddenMenu/com.lge.SprintHiddenMenu.iot.IotHiddenMenuMain
adb shell am start com.lge.networksettings/com.lge.networksettings.MobileNetworkSettings
adb shell am start com.lge.networksettings/.MobileNetworkSettingsForGLOBAL
adb shell am start com.lge.networksettings/.msim.MSimMobileNetworkSubSettings


LTE Service Disabled fix
--------------------------
Insert an original SIM, and the network option will be enabled so it can be changed manually.
OR
Using Quick Shortcuts search for "mobile", Mobile Networks, Network Selection, GSM/UMTS.
OR
adb shell am start com.lge.networksettings/com.lge.networksettings.MobileNetworkSettings


Data fix
---------
5689#*<model#>#
Field Test > NAO Test > NAOT > NAO Setting > NAO Carrier > SPR/None
Field Test > NAO test > NAOT > NAO Setting > NAO Test Toggle > NAO Carrier > SPR/None


No upload data fix
--------------------
Unlock
##786# reset
Unlock again
Disable hands-free
Set APN to IPv4/v6 with TMO
OR
Reset SEC partition


HFA/Hands Free Activation popup disable
----------------------------------------------
adb shell pm uninstall -k --user 0 com.android.LGSetupWizard
