Hello! My name is Matt and I made the mistake of trying to take my prop guards off and put the long screws back into the unit, which messed up all four motors. As I have crashed the unit before and had to send it to DJI for fixing, I'm sure you can imagine my frustration when the air was total silliness this time and didn't even result from flying . I decided to order the 2312 motors and re-solder the wires together but unfortunately that didn't do the trick in the same problem still was there. So for the next step I decided to order for new ESC 2.0's for my unit and though I am an amateur solderer, after a long days process, I was satisfied that I had correctly replace the ESC and the motors. Here is a video of the problem: Unfortunately the motors still are not working and now I am just at a loss for what I should do. Has anyone else experienced this and have an idea of what I should do next? Any advice would be much appreciated!
