RNDP600U upgraded to OS6 stuck at ReadyNAS
Bought a used ReadyNAS RNDP600U (Ultra 6 Plus) as a backup for a Pro Pioneer(RNDP6000) that is still running. Upgraded the RNDP600U to OS6, like the other older model. It ran a few days, I copied a few TB to it. Then after a reboot it got stuck at "ReadyNAS" on the Display, no amount of rebooting does anything.
Things I've tried:
1. Hooked up a monitor and keyboard, the BIOS posts perfectly
2. Replaced the power supply with a new one
3. Replaced DIMMs
4. Replaced CPU fan (only because I broke the original)
5. Made 2 custom OS6 USB boot disks on an 256MB and one on 8GB
6. Booting with and without drives
7. It never gets far enough for the NIC to initialize so No Radiator/Radr/SSH option is available.
8. Booting holding the reset button in the back
9. Booting holding the backup button in the front with a recovery USB stick in the front.
It won't boot to either USB disk(maybe I made them incorrectly)
Based fact the BIOS loads and the moment it tries to start the OS the screen goes blank and it never boots, I suspect the OS load on the EPROM is failing. Anyone know how to reinstall the OS on the EPROM?
I don't care about the data I have triple backups, just want to revive the unit.

Did you check that you're installing the correct OS? Here's a link to the support page for your RNDP600U.
Thank you for responding . The unit has been upgraded to v6 and it is recommended never to downgrade versions, so all the v4 files are useless for this system.

Not quite. That advice is limited to OS-6 downgrades - and even there Netgear says is it safe to downgrade minor releases (6.10.7 to 6.10.5 for example, but not 6.10.7 to 6.9.5). As far as converting from 6.x back to 4.x, Netgear offers no advice, as they don't support OS-6 conversion at all.
It is possible to try converting back to OS-4 again, you'd need to put the 4.2.31 image on the USB recovery disk.
Then immediately do a factory reset (perhaps with a spare disk) - as was needed when you converted to OS 6.

You need to make the USB disk using the OS-4 instructions, but put the OS-6 image on the disk instead of 4.2.x.
It's possible that your VPD is corrupted - though it has somewhat different symptoms. If that's the case, then only Netgear can repair it. Although OS-6 isn't supported on your NAS, the mods have often fixed VPDs in the past as a courtesy.
