I can´t upgrade the RC either. Have tried everything. Also called support. They gonna send a rest file they say, nothing yet.
They made some suggestions like trying different SD card, format the card etc, upgrade through the camera... Nothing works.
As a last try i tried this suggestion
Okay
Here is what I did to clear that upgrade required error.
Download this patch file from here..

Put it on a USB pendrive and update your RC with it.
This is a DJI patch file for this purpose.
Obviously you do this at your own risk etc..
Don´t work either. Nothing happens when i update with this patch.
So now i am downgrading to old firmware again. At support they say i can do this by just putting the old firmware back on the SD card which i have done. Its downgrading the firmware right now and it seems to work. They told me to use the old App and not the Go App as there might be compability issues.
Anyone know if its actually safe to fly after a downgrade? Worried about the batteries being messed with. I have a film job this week end and it just have to work. My first payed job with drones. At support they said if its says safe to fly it is safe...
And thanks DJI for ruining my day. I have bought new USB stick, micro USB cables to try to get it to work but nothing.
