Hope the FW roll back is the fix,
Till now i had no real issues apart from 1 confusing moment when i changed batteries directly after the maiden new FW flight,
After landing i took the battery out i had flown down to 30% and lay it on the hard case in the shade to cool, shoved the next fully charged battery in but when i tried to start the motors an IMU escape warning came up, it said to turn off and restart and if the problem persists contact your dji dealer...or words to that effect,
I turned off and back on a couple of times and it did the same, i then pulled the battery and put the phantom in the shade to cool, tried again a few minutes later and no IMU escape warning,
I did 2 flights the next day again with 2 fully charged batteries and no warning so i kind of forgot the incident and put it down to a software fart.
