Turns off the BHT power
Starts the OS Update
The BHT always performs the full-reset (cold boot) after the
update.
The RAM file system, the registry and the registry data
stored in the FLASH memory are all deleted whenever a
full-reset is performed.
Therefore, resetting the registry is required after the update.
The following steps are strongly recommended for the
registry reset.
1. Create the registry file (*.reg).
Refer to "[13] Registry Editor" for how to create the
registry file (*.reg).
2. Enable the "Startup Launcher" in the "Startup Config" to
automatically deploy the registry file (*.reg) in the "Setup"
folder when a cold boot is performed.
Refer to "[12] StartupConfig" for how to set up.
When the OS update fails, full-reset must be performed
manually to restart the BHT or complete the OS update.
