ReadyNAS RNDU4000 4.2 to OS6 boot failure

I've been wanting to upgrade my legacy NAS to OS6 for some time, so I finally gave it a try yesterday, unsuccessfully.

 

First, my data is backed up, so I don't mind if the solution wipes the disks.

 

I am going from 4.2 to OS6 (I think it was 6.6.0 that I had downloaded).  I went in to the manual upgrade tab, loaded up the .bin, and rebooted when prompted.  Then the NAS would hang at 98% (first time), 80% (second time), and now at 99% with a "upnphttpd.service" message. RAIDar shows storage with "management service is offline" status.

 

What to do?  I've read many threads, but I'm not sure the other solutions will work for me.

  • Did you install the Prep add-on before installing the R4toR6 .bin ? The sole purpose of the Prep add-on is to trigger a factory reset (wipes all data, settings, everything) at the appropriate time.

     

    If you didn't install the Prep add-on you'll need to do a manual factory default using the boot menu.
