Manual reset[/h]The connection is fine but the automatic update does not work anyway?
If after "Connecting (try to reset hardware and start bootloader)..." is not an "OK" coming up after ~3 to 4 dots than you can do as follows:
connect the PCB (i.e. FC) over the ribbon cable direct to the MK-USB (not over a wireless connection!). For the BL-Ctrl use the connector on the side of the MK-USB!
remove jumper from MK-USB
In the KopterTool select the appropriate file and start the update
