    After installing the ZenMuse and PMU on the Phantom I upgraded to 3.14.
    Big mistake. It sends the Phantom into a warm up loop ( 4 yellow flashes) which goes on forever and I can not
    fly the craft.
    In the manual it states that if the warm up lasts longer than 2 minutes to go into advanced calibration.
    Did that and it makes no difference. Clearly a software bug.
    When I downgrade to 3.0 via the backdoor process I can fly the phantom. The Zenmuse and GPS access via the PMU V2 dont work
    under 3.0.
    I see some people have downgraded to 3.12. That would give me access to GPS and Zenmuse.

    How can I downgrade to 3.12 ???? Help would be much appreciated.
