Ok, it sounds like you have a battery issue.
Since you can join the Phantom network, I'll assume that the Phantom turns on, the ESC's beep, etc.
1. Does your Phantom turn on and beep/lights flash?
2. If not, are you turning on the battery correctly by pressing it once and releasing, than immediately pressing again and holding?
3. Assuming you past the Noob stage and can turn it on..... then the Phantoms lights are flashing. What color and sequence are they flashing? If nothing, and your battery is on... your Phantom is very broken. Return to DJI
