Reprogramming your JamBlaster SD card

If the SD card in your jamblaster fails here is how you can reprogram it.

Remove the card from the jamblaster

  1. Remove the four screws
  2. Follow instructions attached or here https://s3.amazonaws.com/jamkazam-repo/MicroSDCardHolderInstructions.pdf to remove the SD card

Two options for programming the SD cards

A. User runs scripts on a linux machine to create SD image
  1. Download the assets here https://s3.amazonaws.com/jamkazam-repo/sdprog-jb.tar.gz
  2. Extract the content to directory with: tar voxf sdprog-jb.tar.gz
  3. cd sdprog-jb
  4. Insert there SD card and find the mount name (http://superuser.com/questions/352598/how-to-find-the-dev-name-of-my-usb-device). . Note by using a SD card with larger capacity, you can store more recordings on the jamblaster.
  5. Run command to burn sd card:
    1. sudo ./prog_sd.sh -sdcard <drivename>
    2. eg: sudo ./prog_sd.sh -sdcard sde
    3. When the script is done it will output a command like this “SUCCESS: Installed software on /dev/sde”
  6. Remove the SD card and return it to Jamblaster
B. User uses a Virtual box to program the SD card
  1. Install virtual box (note Virtual Box currently does NOT seem to work with Windows 10 System – so It must be Windows 7, Mac or Linux 64 bit host system)
  2. for installation videos - see https://www.youtube.com/results?search_query=install+virtualbox
  3. Install the virtual box extensions for the platform extension pack - https://www.virtualbox.org/wiki/Downloads. This is needed for the system to pass through the USB interface from the host to virtual system
  4. Download the jamblaster virtual disk image – https://s3.amazonaws.com/jamkazam-repo/JamBlaster.ova
  5. Start Virtual Box and select “File->Import Appliance” see example on importing here
  6. When the import is done start the system. See - https://s3.amazonaws.com/jamkazam-repo/Screen-2017-02-01-14-55-07.mpeg
  7. NB. If the system says it cannot create the network adapter and offers to create another, just go ahead and create one with default settings. We do not use the network interface so it does not matter.
  8. Connect your USB memory card programmer to host system USB port with the jamblaster SD card - (see https://s3.amazonaws.com/jamkazam-repo/Screen-2017-02-01-14-57-43.mpeg). Note by using a SD card with larger capacity, you can store more recordings on the jamblaster
  9. Open a cmd terminal (shell) in the virtual system
  10. cd sdprog-jb
  11. NB: the password for the jamblaster user is jamblaster. So the username and password are the same.
  12. Run command to burn sd card:
      sudo ./prog_sd.sh -sdcard <drivename>. Most likely the name of drive will be sdb since the virtual box software only has one drive.
    1. eg: sudo ./prog_sd.sh -sdcard sdb
    2. When the script is done it will output a command like this “SUCCESS: Installed software on /dev/sdb”
  13. Remove the SD card and insert in the jamblaster
  14. Shutdown the virtual system

  • I was able to do this on a Mac with virtualbox running Ubuntu. It was a little involved for the average computer user but I'm pretty sure I got it fixed.
  • Great! Please post any ideas on how we could refine the process.
  • If you need assistance with this or want to make other arrangements please contact support@jamkazam.com
  • So I noticed that in order to access the USB SD reader in virtual box, in addition to installing the extension, I needed to go into the settings and add the correct USB filter. Under settings --> ports --> USB in the lower right side it's the icon of the USB cable with a little green plus sign. See image attached.
