u/DaCosmicOne

I recently had to by a new controller for my mini 4K drone cuzz the old one just blew out while charging and won’t turn back on.

I have the new one and it won’t connect (it keeps flashing green) and every time I select join the prompt reads “Unable to connect”.

I’m told this might be a firmware problem but I’m not sure how to upgrade the firmware or if that’s even the issue.

Can someone explain what the issue is???
