Do you need more help with using one of our Support Sticks? Please read the following guide carefully.


USB stick: Things to consider

  • The SIG file needs to be in a folder called mrbeam, all lowercase and without spaces.
  • This folder can only contain one SIG file.
    • If you have used this USB stick with your Mr Beam II before, please make sure that there are no old/other SIG files within the mrbeam-folder on your USB stick.
  • The USB stick should be FAT32 formatted:
    • Most of the sticks have this format out of the box. However, please double check that in the properties of your USB stick.
  • The USB stick needs to have at least 100 MB free space.
  • The USB stick needs to be USB 2.0 compatible.


Did your Mr Beam show any color other than the expected green?

  • Blue: there might be something wrong with the USB stick or its formatting. Please check that the USB stick is formatted FAT32 or simply try with another USB stick.
  • Purple: make sure that the SIG file is inside of the mrbeam folder. It's important that the SIG file's name was not changed.
  • Red: please contact the Mr Beam Support.
  • Yellow: please contact the Mr Beam Support. (signature mismatch)
  • Orange: please contact the Mr Beam Support. (serial mismatch)
