marshmallow 6.0 secret code and lte settings lg g3 cat 6 f460s
After updating my mobile to mm 6.0 the new secrete code for my g3 cat 6 model number f460s is *#546368#*460# and service code is 5457#*460# .
Also LTE was not working for me, in India Vodafone 4g, (it was showing lte icon though) so i created a new APN by going to settings then go to tethering & networks >> Mobile Networks >> Access Point names >> New APN >> Name: Globe , APN: HTTP.GLOBE.COM.PH, leave everything to not set. This worked for me like a charm. Thanks Naren
PS: if someone knows how to enable VOLTE on mm 6.0 please update. (Also i enabled iSim somewhere in secret menu)
