Phantom Vision 2 lift off flipping and falling

Recently my Phantom 2 vision has started flipping over repeatedly just at take off or when it reaches a few feet in the air.

I have tried several things based on reading forum posts to correct the problem but nothing is working..

(1) re calibrated compass..no help
(2) unplugged the compass..no help
(3) recalibrated basic and advanced IMU with laptop... All values well within normal ranges... No help
(4) checked props for correct orientation and spin.. All correct... No help
(5) held the drone by the landing gear and had helper throttle up to full throttle to see if the quad was pulling any direction but straight up.... No issues and did not help
(5)motor test... Full throttle and no stuttering or cutting out... All motors respond with various txt inputs
(6) full take off throttle.. ie.not easing it up.... No help
(7) correct mix setting on assistant software


I am currently running firmware 3.08
NaZa mode


Any ideas.....??..??



Did you figure out the problem? I have the same thing ..out of no where :-(
