[KB1469] Always upgrade from ClickShare version 01.03 to 01.04 before moving to version 01.05 or higher versions? (FAQ)

Short Description

Important notice for updating to software version 01.05 and above on CSC-1 The firmware versions 01.04 and above are digitally signed to increase their level of security. To change from an unsigned firmware version to signed firmware, an intermediate step is required. This step is included in firmware version 01.04. As a result, to update from firmware version 01.03 to firmware version 01.05 you must first update from version 01.03 to 01.04, and then update the firmware from version 01.04 to 01.05 or higher. When updating firmware version 01.04 to higher versions, no special action is required. Downgrading a firmware version to an older version does not require an intermediate step.
