I bought this unit used and it worked right out of the box; starting/stopping, pairing with the transmitter, viewing real time with the app etc. I was able to put in about 10 hours of flight time in before the issue I describe below began. After researching the available software etc I used the DJI Phantom 2 Assistant version 3.08 software to upgrade the firmware (according to DJI's) website from 3.12 to 3.14. After doing this I am no longer able to start the phantom or get the iPhone DJI Phantom Vision software to view it. The perplexing part is if I use the transmitter I can control the camera & when hooked up to the computer the assistant software recognizes the joy stick movement but will not allow it to start. Some resources; the unable to start/stop pairing issue, confirmation of the software recognizing the controller & attached is a snapshot of the firmware versions. I have tried quite a few things; using the assistant software 3.06 to re-install the firmware, used the assistant 3.08 software to re-install each component of the firmware (i.e. main board, zen muse etc). While researching the P330CB-H3-2D board & how to possibly perform a factory reset, I came across this thread (Install OpenWRT WebUI on Repeater/P2V+) regarding the WPA settings on the controller & drone. The controller wireless network (i.e Phantom_XXXXXX) is accessible but the hidden WPA SSID 'FC200_XXXXXX' (where XXXXXX is the last 3 octets of the MAC identifier) is not accessible even though the signal for the WPA is present on channel 7. I believe this is where my problem is and have even gone so far as to try every permeable SSID corresponding to what should be the default (i.e. FC200_038CB9). Can anyone provide some insight? Where I have already spent more than I wanted to on a used drone to determine if I want a nicer one I don't really want (or can afford) to dump money into an expensive repair of the unit. Any and all help is appreciated!
