Downgrade lock

The downgrade lock prevents the downgrade of firmware upgrades that have already been
performed to correct errors.
Note
Upgrade higher firmware versions
Components with higher firmware versions are fully downwards compatible with components
with lower firmware versions. Following a firmware upgrade, a component will also operate
without restrictions with components that have a lower firmware version.
Note
Firmware retrofit of a Control Unit
A higher firmware version is also characterized by having a larger range of functions than a
lower firmware version. If you downgrade a Control Unit from a higher to a lower firmware
version, it is possible that certain functions will no longer be available.
