hello I purchased an i1 from a friend of mine and am looking to register it under my name and give it its name. Currently it has the old owner info How do I make this change? Thanks

Unfortunately, you cannot change the email that the unit is registered to, but you can log into your DJI Account in order to have the new flight logs save to your account. For the device name, you can go to you General settings in the DJI Go app via the Camera View in order to change it. It would be the last available option at the bottom of the page. This will only show up when the unit is powered on and connected to the Go app.
