[Nexus 6 Android Development] ziddey:
Anyone using this rom with Sprint? LTE only works for a while on the first boot, after which it can't establish the data connection unless forced to 3G mode.

Doing *#*#INFO#*#* and selecting "Phone information" crashes.

Unfortunately I didn't capture a full logcat, but I do have a snippet, grepping for Sprint:

Went back to LOS 14.1 and LTE is working as it should again.
