ReadyNas Ultra 2 booting issue - CASE #18994884 - SOLVED

Updated with case number. After browsing the forums, I did try to do a firmware reinstall. I am able to enter boot mode and select the OS Reinstall option. Then when I execute the option by pressing the reset button again, the RAIDAR utility shows as status "booting", "updating", and then again, nothing, ReadyNAS cannot be found anymore. Reinstall of the firmware started over an hour ago, but no progress. Just the green Disk1 led is on, fan spins, but no further activity. I did remove one of the two disks before executing the firmware reinstall just in case anything would happen to my data. I do have an external backup, but it is from several months ago, so I wouldn't want to lose the data accumulated since...
