Is there a way of rolling back the firmware to .200  and going back to Go4 v4.0.1  , i am desperate to do this, is there any tech's that know a way?  the assistant 2 shows no way of doing this !

It seems that DJI is now only allowing rollback to .0400 through the app and Assistant. I'm not sure if there's another way to do it.

i know .200 had its issues, and Go4 4.0.1,   but it was the best firmware/software to date,  best overall control,  each update since it has flown worse,   surely there must be a way?  even if i have to buy an IOS device.  Does anyone know if there are any APK files available or other ways of doing this?
