During the update, some customers reported that the update failed—always together with some kind of 'endlessly flashing screen'.

Most of the times, reasons are (missing) previous updates and the behavior of the USB connection on the computer (which has been solved with the new VBar Control Manager), or a misconfigured screenshot app (switch assignment which makes hundreds of screenshots, e.g. screenshot assigned to motor switch, so a screenshot is made every time the motor is switched on and off—and so fills up the memory). The screeeshot issue was solved in a previous bugfix, the maximum number of screenshots was limited—but of course, if the update wasn't made ...

Please follow these steps, check for functionality after each step. Depending on the cause of the situation,  all steps are necessary!

The new VBar Control Manager is required, as written in the update instructions. People using the old VBar Control Manager  may run into troubles, too.

If you have a "No System Config" screen: follow our FAQ here
