So all of a sudden my 4G stops working. The LTE and Spark icon still display on status bar but data fails to work. Switching phone to CDMA mode (3G) and data works like a charm. Tried multiple profile and prl updates, tried reactivating multiple time via ##72786# and ##update#, tried factory resetting and even restoring phone via download mode. Multiple calls to Boost have been useless. Right now I'm waiting on their engineering department to look into issue. While I'm waiting I figured I'd see if anyone else has had this issue or anything close?
