Unfortunately, there is no txt file on the sd card. I did the update lugging in the P4 directly to the iPhone as instructed via the app. Did get an "update successful" message on the app.Paul Tortora, can you post the log from your memory card? It should be in "MISC\LOG\P4_FW_LOG_AB.txt".
Have you updated your own P4 yet...and if so, which method did you use? I haven't tried mine yet, as I'm waiting to see where this thread goes!I got it to run on my MacBook Pro. I had to go into "System Preferences" --> "Security & Privacy" to allow DJI Assistant to run. After doing that, I was able to start it up and login.
Update: I contacted DJI tech support and they suggested I delete the DJI Go app on my iPhone, reinstall it and then power everything up. I followed their suggestion and It did indeed correct the communication error between the RC and the P4. Specifically, it updated the RC from 1.5.8 to 1.6.0. I then recalibrate the IMU, compass and gyro. Much better but still a couple of issues. Now when I power up, I get a red triangle telling me to wait until the IMU warms up but it takes much longer for it to cycle through compared to the start up time prior to the update. Second issue is that the auto lift off button on the Go App never comes on as an option, even when you get a green ready to fly message. If I manually lift the P4 the auto land button becomes visible and if selected, works but again, the auto lift off never comes on as an option. Any thoughts?
