I  tried updating the firmware to version V02.00.0700 using DJI Assitant 2 for Phantom (Mac) but it kept failing at 55% after several attempts (snapshot #1 below).

However when I restart the P4 and DJI Assitant 2 for Phantom (Mac) it displays #2 below.

Is the firmware V02.00.0700 updated according to attached snapshot ?

When runnng DJI Go App on iPhone I have no firmware update warnings; therefore I assume controller firmware is up to date ?

I get the following error on the DJI Go App :  Air Encoder Error 0x2800020 (snapshot #3 below)

Advice please.

Thank-you.
