So I have been unable to fly my drone for some time now due to the issue that the drone will not take an firware update. Here is the list of items tried and hoping that someone can relate and help.
Upgrading through the go app - When starting this the ipad will ask to beging the update and after hitting it nothing happens. Reset, dleted and redownloaded the app and all stays the same.

DGI Assistant 2 - Everything seems normal on start up. I have down graded and also tried taking thig back to factory and remains the same. It starts the download fine until the update starts. Once it hits 36% the drone then turns on and off twice and remains on then until the battery dies after a an hour nad a half. The percentage stays at the 36% and never changes.

When trying to fly it is a mess. the video oges in and out and the gymbal won't move.

Thanks for any help you can provide.

My Phantom 4 pro doeas the same. But I can't even get drone and RC to link, so I can't do anything.

I would love to be able to go all to factory defaults and update from there.
Ever sense I did the latest update it just bricked the whole thing. I can't get
any firmware updates to work, they stop because the drone can't link.
I don't know how this stuff happens.
I've had this drone for 2 years.
