I got my LG D802 from HK. Coming back to where I work ( China ), I found out it doesn't have any option for LTE (4G) in the menu or else. I googled the problem and found I can use the hidden menu and activate LTE for every time I boot my device ( it's a temporary solution as it's gone again and need to re-enabled each time I restart my device ).
So, anybody found any solution for this? I mean a permanent solution which doesn't need enabling after every restart.
