I had flashed cm13 on my LG LS990 yesterday and everything worked fine except for the mobile data connection. When I tried to create an access point, I got the message "Access Point Name settings are not available for this user" I tried deleting telephony.db but that didn't work. I also flashed a zip file of a possible fix that i got off another website, but that didn't work too. Please help. Thank you in advance.
