Hi. I am sorry to know that your DJI Phantom 4 Pro backward sensor is not calibrating. For the calibration issue, have you tried to uninstall and reinstall the DJI Assistant 2? I would recommend using a different computer or use the recommended resolution. For recommended display resolution (usually 14 inches for 1366*768 or 1440*900; 17 inches for 1366*768 or 1280*720; 19 inches for 1366*768 or 1440*900; 22 inches for 1680) *1050 or 1920*1080; 24 inches for 1920*1080 or 1920*1200). Please keep us posted or updated for us to be able to assists you further. Thank you.

Thanks for recommend.I have used both my computer laptop to calibration this Phantom 4 pro but both failed.I have were calibration my 2 other phantom 4 standard and Pro used this Assistant 2 and these work fine but this Phantom 4 Pro just bought on Ebay is failed.Uninstall and download new DJI assistant 2 but not solve.the problem just with backward sensor.Start calibrating forward sensor ok then downward sensor ok then backward sensor first round ok but second round problem come at 60% of round,the App said :sensor moved incorrect direction,try again,then failed .repeat that some time but finally complete.But then in calibration collecting transmitting step from 0% to 90% then failed to complete
