Purchased P3 Standard yesterday. Installed dji go on android smartphone (LG G4), update notice came up. Downloaded to device the update, followed instructions to connect to p3s via it's wifi. Updated started, got to 14% then error. Said to shut down all, reconnect and restart update process. Did that, not it (p3s) beeps like hell, like at least two beep codes at once and update only reaches 4% before error. Is there a 'manual' means of updating firmware via usb? I see two usb ports on the p3s. Is the SD card for the camera only? About ready to send back to retailer for a refund and forget the whole experience.
