If a firmware update fails to complete, Promote Control may become inoperable. To restore Promote Control, a complete and valid firmware must be applied – and if Promote Control is completely inoperable, the method described in Performing a Firmware Update will not work.
In this situation, use the following emergency workflow:
1.Download the latest firmware update file from http://www.promotesystems.com/
2.Download the latest version of the Promote Control firmware update application from http://www.promotesystems.com/ and install it on your computer.
3.Install a fresh set of batteries in Promote Control and/or connect the optional AC adapter as described in Using an AC Adapter.
4.Remove the protective cap from the RESET button located on the back of Promote Control (see Controls section for details).
5.Connect Promote Control to your computer using the supplied white USB cable.
6.Hold down the Promote Control "Mode" button and use a straightened paper clip to press the RESET button.
7.Launch the firmware update application and proceed with the regular firmware update from Step 6 as described in Performing a Firmware Update section.
8.Allow the firmware installation to finish before disconnecting or using the unit.
After the firmware update is finished, disconnect Promote Control from the computer and press the "Power" button to confirm correct operation. Promote Control will attempt to restore all saved settings even after a firmware update failure. In the unlikely event that settings are not restored, re-enter them manually.
