Why is the minimum FW version 6.52.0003 for these models?
In November 2018 an internal hardware (HW) change was made to these models that requires this new minimum FW version. The new HW version isn't backwards compatible with older FW versions.
If the unit has been upgraded to a higher version, how do I get the 6.52.0003 FW?
This FW version was only released for these three models, so it isn't available on the Bosch Download Store. At this time, please contact Technical Support to obtain this FW.
