My Mavic Pro prompted me for an update yesterday v01.04.0300,tried to  update using my Crystalsky via WIFI.Would not work,so then I took it to  the PC using DJI Assistant 2.Have made approx 20-30 attempts,EVERY time  it stops at 40%(see screenshot below).Tried downgrading then  upgrading,re-setting all the settings,delete and re-installing the DJI  Assistant and end up at the same point every time.At least 4 hours of my  time wasted,would really appreciate some help here!! I know I could  just leave it at the older firmware,but I dont like being nagged to  update every time I boot it up,and beyond that its become a battle I  dont want to lose!!
