Rooted stock ROM phone. To make a long story short I made a bad flash with an incompatible file. Restoring a backup resolved everything with one exception: 4G. Data works fine through 3G or wifi. No 4G data for apps. Curiously opening settings > Activate This Device pops spark right up if it's enabled in settings > More Networks > Mobile Networks > Network Mode but that's the only time. Also noted are APNs only list 3 "Wholesales" options which are all mostly empty.
The apns-config.xml file is present in /system/etc. All the appropriate data appears to be contained within it. Wiping does not restore the APN settings. Factory reset does not work either. Reflashing the stock rooted ROM does not resolve it. What else can I do?
