Hi Everyone

    Not sure what downlaods you are using. These steps include the files that should work.

     

    1. Upload PREPR4TOR6_0.1-x86.bin as an add-on using the ReadyNAS web gui, but do not reboot afterwards (avoids the need to do manual factory resets)
    2. Upload R4toR6_6.9.5.bin using the ReadyNAS web gui firmware update
    3. After you upload the addon+firmware and reboot, it will update the firmware and start a factory default.
    4. Go through the setup process on the converted NAS 
    5. Update the NAS to the current OS 6 (check for updates will NOT work).

      the web GUI shows firmware version 

      and also RAIDar show this 

       

  • Additional note:

    I used Firefox and set it to tls and also tried a older version of opera, i also noticed that there is no addon in in the addon tab.
