NV+ ERR BAD FIRMWARE
So I have an NV+ (RND4425v1) that is reporting ERR BAD FIRMWARE. This occurred after my home lost power. I'm not sure why it didn't shutdown on its own as I have it monitoring my UPS. The good new...
I suggest you try booting in read-only mode using each possible set of three drives and see if you get better results.
I think what they call "NAND recovery" in the ancient documentation is what we now call USB recovery.
Thanks sandshark... how exactly do you boot in "read only" mode?

You can't with the NV+. But you can boot it up skipping the volume check (which should be good enough for the purpose here). See pages 23-24 here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
Another option is to try removing all the disks (labeling by slot), and then try to do a factory install on a spare disk (which will be reformatted). If that works, then that will tell you that a USB recovery isn't needed.
Thanks Stephen. So I removed the disk and labeled them. Put in 3 old 750gb drives and did a factory reset. The system booted just fine. But then I could not get logged into the NV+. I finally found an old post from you that suggested using netgear1 as the password and low and behold I got into FrontView. Thanks for that posting as well!
So I put the original 4 disks back in and powered on the unit. It said "booting..." "Please wait". then about a minute later the message changes to just "booting..." After about a minute, I'm back to "ERR BAD FIRMWARE". RAIDar is once again seeing the NV+ but reports a status of Corrupt root. At this point I don't know where to do except for a factory reset and lose all my data that wasn't backed up. It's not a whole lot but will really be a pain to recreate.

This means that the OS partition on the disks as somehow gotten corrupted (and based on the earlier posts an OS reinstall didn't fix it).

If you can connect at least three of the disks to a PC you could attempt to offload the data - either using a linux LiveCD and mounting the raid array manually, or by using R-Studio ( https://www.r-studio.com/ )
