So, I'm making a game for Firefox OS, and just got my ZTE Open C to test it on. I've been running it on the simulator until now. I uploaded a version of it, and it kinda worked, the accelerometer wasn't working for some reason, but that's not the problem. After I installed some apps and updated the OS, I went back to try a newer version of the program, and it won't upload. I press the "Update" button, and it won't do anything. It still works fine on the simulator, and it does won't upload the old version now too. Help!
