There is a possibility that you could brick your NAS with these instructions. Please make sure that you read the entire page carefully. These instructions are intended for (and were tested successfully with) Linkstation Mini models LS-WSxxxxGL/R1. Other models should download the correct TFTP and Updater software from Buffalo. This procedure is not guaranteed to work for your Linkstation Mini model. Proceed at your own risk.

  5. Change computer IP address to (subnet
  6. Download and extract TFTP boot recovery software ( )
  7. Download and extract LSUpdater software on computer ( http://www.buffalotech.com/support/getfile/lswsgl-106.zip )
  8. Adjust [Flags] section in LSUpdater.ini
     VersionCheck = 0
  9. Add section to LSUpdater.ini

  10. Disable firewall on your computer (firewalls can interfere with install)

  12. Boot device in EM mode (power off, hold function button while powering on, release function button when blue light starts flashing, press and release function button again, press function button when red light starts flashing, repeat until TFTP boot succeeds)
  13. Wait for TFTP server to send images to device (initrd.buffalo and uImage.buffalo)
  14. Do not proceed unless the TFTP server indicates successful transfer of initrd.buffalo and uImage.buffalo

  15. Close TFTP Boot window

    The following commands will completely erase and rebuild the Linkstation Mini. ABSOLUTELY ALL DATA ON THE DEVICE WILL BE LOST. Make sure that you are using the the correct firmware for the intended device (i.e. LS-WSxxxxGL/R1). If you have selected the wrong firmware and/or device, THEN THIS PROCEDURE WILL BRICK YOUR DEVICE. Proceed at your own risk.

  20. Select all checkboxes in both "Update" and "Config" frames (update boot, update kernel, update initrd, update rootfs, do not check version, rebuild partition table, delete user-config, force update)
  21. Make sure that you have selected the correct device, then click on the "Update" button to begin the update
  22. Confirm that you want to format and update the target device
  23. Wait for update process to complete
  24. Close LSUpdater utility.
  25. Enable firewall on your computer
  26. This will restore the device to factory settings; however, the web interface will be in Japanese language. Follow these steps to change to the language and character set of your choice...

  27. Open the device web interface in your browser (should be [1]... on DHCP networks, consult the router DHCP client list)
  28. Login to device (user = admin, password = password)
  29. Change the language and character set as needed using second menu item (looks like folded paper)

Congratulations! You should now have a Linkstation Mini reverted to factory settings.
