Hi all,

I've tried everything imaginable to update the firmware.  Fomatted the SD Card, tried the update using the app.  Tried updating with the Assitant using three different computers and nothing works.  With the app, at times it says it is updated and others it is not.  It won't recognize the SD card (tried three different ones) and the camera will freeze in black and white.

When attempting to use the assisant, it gets to 36% and then fails.

There has been to damage to the aircraft or crashes.

It will take off and fly, put is unstable.  Plus no camera or recording.  Not fun.

Any advice?

TURN OFF THE CONTROLLER..IT WILL WORK!!!!!!!

Thanks for the reply.

I tried that, still no luck.  It won't recognize the SD card.   I just hooked everything up after 5 failed updates and the controller says it is updated.  But I've been through this before and it will alternate between "updated" and "requires update".  I also get  Processor chip critically overheated. Th e aircraft will power off in 30 sends" (but it doesn't power off).

This so frustrating!!!

Make sure you have a plenty batery , try another Usb Cable or maybe is a Sd Card Problem .... i would try another one ( class 10)
