The instructions below describe how to force the Maestro into bootloader mode by performing a hard bootloader reset. Most customers do not need to use these instructions, but they can be used as a last resort in case something has gone wrong.
One reason to do a hard bootloader reset is if you accidentally loaded the wrong firmware onto your Maestro. The result of loading the wrong firmware is that your Maestro will have corrupted, unusable firmware. The Maestro will not be recognized by your computer and it will probably not blink any of its LEDs. In this case, the normal method for getting the Maestro into bootloader mode through the Maestro Control Center will not work, and you will have to resort to a hard bootloader reset. After that, the Maestro will be in bootloader mode and you can restore the Maestro’s correct firmware.
This might require a few tries. Once it works, you should see the green LED double-blinking, and the Maestro’s bootloader should be visible in your Device Manager (if you are using Windows). Then you can stop shorting together the pads and retry the firmware upgrade procedure in Section 4.f starting at step 7.
