Important notice for updating to software version 01.05 and above on CSC-1
Please note that firmware versions 01.04 and above are digitally signed to raise security level. 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, updating firmware version 01.03 to firmware version 01.05 requires first an update from version 01.03 to 01.04, followed by an update from 01.04 to 01.05. 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.
Flows to follow when up or downgrading between signed and unsigned versions:
