if the update with ProfiLuxControl failed it is possible to update with another tool

1. download http://support.aquariumcomputer.com/...oad.php?did=48
2. save it somewhere you will find it, no installation required
3. start "flash.exe"
4. select "MB91F467D" as controller, 4MHz, navigate to the firmware file (click "open")
5. check the interface (under "set environment")
6. disconnect ProfiLux 3 from power (it is not necessary to open the enclosure and to set a jumper like it was ProfiLux II!)
7. now click "full operation" - ProfiLux still has no power!
8. plug in the DC-connector - ProfiLux has now power again and the download should start

Hint: If the update with ProfiLuxControl failed then there is maybe something wrong with your connection from PC to ProfiLux 3. Please ensure that your connection is stable and reliable before attempting to update with ProfiLuxControl or this tool, e.g. check the USB driver and update it if possible.

Here you find the detailed manual for flashing the firmware:
