Hello all. Tuesday, my data connection suddenly dropped on my thunderbolt. Thinking it was a network issue, I left it for morning, but still no luck! When I go to settings /about/network, it shows I am on the LTE network, but I have no 4g/data connection. Reading other forums, I found the ##778 menu option, where it says to change the modem settings Rev.A to enable. I restarted the phone and saw 3g pop up for a moment, but once it connected to LTE again, the data was gone. I have played around with a number of modem settings, and 3/4g switch items, but nothing has been able to get me better than a 3g connection. Does anyone have suggestions on how to fix this or what could be wrong? As an additional piece of info, I am rooted, and reflashed my room with a full wipe, and had no luck with that either. Thank you!
