I have to say this happens to my TM nano 3T at least twice a week. I have the blue hd skin installed and it will just show the loading spinning wheel and box will become useless just the channel playing in the background that it is stuck on. I will then have to hard power off the box via back switch. This happened with Apollo, Hades, 3.2, 4.0 and 4.1 so this is not a firmware issue but somewhat frustrating. My friend also purchased this box at the same time and is having similar issues. Any help or ideas would be greatly appreciated.
