I need your help about an issue I encountered on my Optimus G E975.
I'm French, my carrier is Free and I recently activated the 4G (LTE) option proposed in my plan, no problem.
I then wanted to enable the 4G network mode in my stock ROM, here comes the problem !
The LG's ROM only let me choose between 2G, 2G/3G or 3G networks. My phone is compatible, my APN are ok, Free's settings are ok too... So I decided to modify the build.prop file to force the 4G choice. I edited those lines :
- ro.telephony.default_network (changed value from 9 to 10, referring to a Google Code thread)
- telephony.lteOnCdmaDevice=1 into telephony.lteOnGsmDevice=1
I can now choose 2G/3G/4G setting and it seems to be working, but after each reboot, it doesn't stay checked and goes back to "2G/3G".
Can you help me please ?
