I put my battery on the Ar Drone, and ALL Led's flash red also the one under it.
When I connect my Iphone to it, and I open the app, it says there is an update avaible, I can either press Ok or cancel.
When I try to press Ok, the sending file comes up, but after 5 secs it says Wifi not avaible, Connect to your Ar drone, and if I press Cancel, I get the screen, with the platform and it says control link not availble.

Is it the Mainboard thats not working or what?

Hope anyone can help, Thanks
