I had this same issue and was about to give up. Then I removed the top shell and carefully removed the cables and wires from the Naza unit. (I took pictures of the connections and general set up so I would know how to put it back together.) I took a screwdriver handle and sharply whacked the Naza unit once, very sharply on the side opposite the Naza logo. (I did not remove the Naza from the circuit board.)
Then I put it all back together, plugged it into the assistant software and did an "Advanced Calibration." I unplugged everything and shut it down. Then I took it outside and to my relief, IT WORKED!
I flew it conservatively for about 8 minutes in GPS mode and it flew perfectly.
I don't really know what I did to fix it, specifically, but somehow, something I did worked.
DJI really needs to provide a software solution fix for this Red-Green-Yellow, Error 25. I paid almost $700 for my Phantom, and at that price it shouldn't screw up the accelerometer every time I have a hard landing. Otherwise this is a toy - and I'll invest in an Arduino Quad when I'm ready to upgrade!
