Hi Pilots,

First of all ... sorry for my worse english! I am just a german! ;-)

A couple of day ago i bought a new P3S. First flight with no problems. After the first flight the app said that there's a new firmware. So i do the update. On my second flight i mentioned that the video signal is lost just after 50 meters, but i can returned. I read a lot here and once someone from dji meantioned to downgrade the firmware to see if the problems will be fixed. So i downgrade the P3S Firmware to 1.6.07 without any errors, but after restarting the copter a mcu Error lights up in dark red and it says that the barometer has an error. I still tried to calibrate the IMU, and/or up- and downgrade the firmware again. The error is still there.

Anybody a suggestion how to fix it? I don't think that it is a hardware failure, cause it just happened while downgrading.

You didn't have to upgrade it. Open a ticket, you might even get a free replacement.

sure, i just thought that there will be a easy and simple solution, cause i don't want to wait weeks till i get it back! ;-)

Could you please find the update log file and post it here? I'll help to check it.
