As a reminder, when updating the machines with new FW it is crucial that the process is being done with the embroidery module and the BSR foot disconnected.
The single machine must be updated first. Afterwards, when the BSR foot or the embroidery unit is automatically loading the appropriate FW into these modules.
Not updating the machine first can result in undesirable performance behavior of the machine and the embroidery module.
