I just receieved the 2nd Gen starter kit. I registered the Sim card successfully. However, the network LED and the tri-color LED have never turned on when I apply power. I have tried to connect to the board in bash. When I put in the command adb devices it says that no devices are found. I am thinking maybe it is a harware issue but wanted to check the forum before I made arrangments for an exchange. I have been told to check and if needed to change the APN. I can't do this without the ability to communicate with the board.
