I got my brand new P3P yesterday, downloaded the GoApp (2.7.2) to my Samsung tablet, upgraded aircarft to 1.8.80 and the GoApp popped up a message to upgrade the RC. So I downloaded and started to upgrade the RC via the GoApp with f/w v. 1.6. The upgrade ended succesfully and the left led turned solid green. A couple of hours later I prepared for the first flight and I turned on the RC and the aircarft. The link was succesful, but I was surprised to see again a pop-up message in the GoApp to upgrade (again!) the RC... The message indicated that the f/w was downloaded and the upgrade was ready to start. So I hit start... Another suprise hit me as the new upgrade was for the same version that I already succesfully installed a few hours earlier: 1.6 !!! So I got a magical GoApp screen telling me that the RC was upgrading from v. 1.6 to v. 1.6 !!! The worst was yet to come, as the upgrade got stuck at 45% ... Almost half an hour later a decided to (abruptly) turn off the RC, as there was no progress and the buzzer started to sound strange. When I turned on again the RC, it connected to the GoApp, but a few seconds later the red led started to blink fast and the buzzer was signaling an error. The app displays connection error. I tried to perform f/w upgrade with all 3 alternative methods, but all failed.... I tried to downgrade the RC f/w but there is no f/w available in the downgrade list. I re-installed the GoApp but there is no message to upgrade the RC any longer. Did anybody have a similar experience? Any ideas?
