need a little help here. new to rooting and as we all know, 4g seems to drop out from time to time on the GN. well it was out for me for about 10 minutes so i thought i would try to toggle the data off and then back on. well when i did this, it never came back on and showed no connection. before it would show either 4g or 3g with gray bars but now it shows just gray bars. i cannot figure out how to get my data to reconnect. any suggestions?
