Reviving an old thread. I had the same problem while flying in the evening (by the time i wanted to land, it was pretty dark). After taking off, i disabled VPS cos I might go low over water and wanted to fly by visual. After that I went up to about 200 m, and wanted to descend to land. I switched the VPS back, but I couldn't descend at all. Tried to on-off VPS, Go app, and even remote, but that didn't help. Eventually I managed to move the Mavic over a grass field with 1% left and checked that the area was clear before the power cut at an altitude of 39 m. Fell into the ground, cracked 2 blades and got some dirt under 1 motor. Gonna get it checked by a friend soon.
