Universal DreamUp 1.3

Loads compatible firmware and flashes the Dreambox hardware. Flashes the files in 15 minutes. Calculates the CRC32 and STB once the flashing finished. Erases the ROM from the memory to completely wipe it and delete any other errors that might appear.

This is the tool required to flash your Box. It is very easy to use and take about 15 minutes to complete the flashing of image.
Once completed, it will calculate CRC32 on STB, erase flash as well as flashing from its memory. Hopefully all these simple steps will serve as an alternative just in case you are not able to flash your Dreambox decoders by any means.
