do us a great service and rip that sucker apart down to the circuit boards. there is a pretty big demand for info on a factory reset and there has got to be something on the inspire some where that would hint how to do it. when these things get sent back for repair they HAVE to plug it in to some port for diagnosis somewhere that allows them to clear everything out. maybe there is motherboard battery, a paper clip pin hole button somewhere or maybe a hidden micro usb port berried deep within. take it apart and tell us what you find. i will con-seed there is good chance the dji factory might just put the a/c into flight data mode and hook into the port in the back with their classified software they wont give us to diagnose software problems, in any case for those who are forced into replacing parts some pictures posted of what all the parts look like dissembled will more than likely do a lot of people some good saving time and money since DJI is reluctant to give us such information.
