ReadyNAS Ultra 6 (RNDP600U) stuck at ReadyNAS boot screen two days after OS6 (6.10) upgrade
Very similar to this thread, I upgraded my ReadyNAS Ultra 6 (RNDP600U) from OS4 (v4.2.31) to OS6 (v6.9.5) only because I lost access to the ReadyNAS Admin console from modern-day internet browsers. ...
If you can't get to the boot menu, Flash corruption is a possibility. USB recovery for a legacy unit converted to OS6 requires that you create an OS4.2.x style recovery media but with the OS6 image file or that you recover to OS4.2.x (using a spare drive) and then convert again to OS6. Unfortunately, with that level of flash corruption, your VPD file may also be corrupt, which only Netgear can repair.
Of course, there are also a lot of non-repairable things it can be. The display will say "ReadyNAS" with just 5V present -- the NAS doesn't even have to try to boot. Adding a VGA cable to the internal VGA header can help in further diagnosis.
This was an interesting idea on trying the VGA cable. I popped the case open but could not find any (obvious) VGA ports on the motherboard. (See the attached picture of the motherboard).

VGA header, not VGA port. You need an adapter. Not something I've used myself, but I believe the VGA header is here:
There is some more info on this here: https://www.truenas.com/community/threads/freenas-on-readynas-pro-6.24666/
That's the location for the Pro6 and Ultra 6 Plus. It looks the same, but is in another location, on the Ultra 6. The title of the thread is confusing, because it says Ultra 6 but gives the part number for an Ultra 6 Plus.

FWIW, my picture is an editted version of the one posted by OnlineUser. So I am thinking this is an Ultra 6 Plus, and not an Ultra.
StephenB Please see my updated status. Any thoughts on "MBR H error" and the memory upgrade? Thank you!

I believe the MBR H error indicates a corrupted flash. Unfortunately, that is not something I know how to fix. But a USB recovery might work. Note you need to use the recovery setup for OS 4.2 systems.
As far as memory goes, I've been recommending that people upgrade to at least 2 GB of RAM before converting to OS-6 for quite a while now. The Ultra 6 Plus (which is what you have) can handle some 4 GB modules (so 2x4GB is the max). But compatible modules are hard to find, and generally quite expensive. So I normally recommend 2x2GB for the Ultra 6 Plus and the Pro 6.
