I am having a little issue. I recently updated to KK and jut didnt like how it preformed. I .toted back to ZV7 to start fresh, this is when I noticed I had a sim card in my statusbar with a little X on it. Then I noticed that I had no LTE. I can't figure out if I did something wrong or what.
I had one of my developer friends walk me through a few things that he had to do on the G Flex, which was toting 5 or more time till that sim card was recognized, well mine still doesnt work. heck I even went into Sprint to have them check it out, and all they did was replace and scan in a new LTE card.
Could me Sim slot be turned off? or could it be fried?
