Hi guys, I never once had a problem with my P3S up until its recent 1.9.20 update. I updated via wifi and everything seemed to check out ok. After updating I tried to do a flight but I could not get the AC to connect to the remote. Link indicator lights were both red on the AC and the RC. Tried re-binding multiple times but still nothing. I then checked the FW on the RC and it said 'Current Version 1.7.90 even just after updating to 1.9.20. I then tried updating again through the DJI Go app, the only version on the drop down list was 1.9.20, it seemed to download and install successfully but its still showing 1.7.90 as the current version. I still cannot get it to update or even detect the AC at all. I think I tried pretty much everything even multiple devices. Even tried downgrading the AC back down to 1.7.90 via SD card but still cannot get the RC to update or detect the AC. Is there any way to flash the firmware on the RC or even force it to update. Would there be certain contacts on its circuit board to flash it back to factory defaults? Any Suggestions.
