Nucleus failed to come back up after being shutdown. No output on HDMI A, although power LED illuminated.
Decided to remove the internal SSD which hosts Roon Nucleus OS. Now full output on HDMI interface and asking for boot media. Put internal SSD back in , same no output via HDMI. Assume internal SSD failure.
I have purchased 256GB MZ-V8V250BW to replace the Kingston SSD. However, I followed this guide: https://help.roonlabs.com/portal/en/kb/articles/roonos-recovery and the USB stick does not boot using Etcher. This appears to be a problem with the underlining image?
I tested to confirm that the USB stick and setup is boot capable, by using a standard Ubuntu 22 Grub and works fine with boot menu given at startup.
How can I get the Nucleus OS back up and running? My ideal end state is to have the Web Interface as before with Roon OS. Don’t mind doing any advanced configuration or procedures.
Please let me know how to proceed. Note: I also tried by-passing Etcher and using "sudo dd ■■=10m if=roonbox-linuxx64-nuc4-usb-factoryreset.img of=/dev/rdisk4 conv=sync " and this has the same result as Etcher.
Could you please share a screenshot of what you see after pressing the F10 key on your keyboard? Make sure to continue holding the F10 key until a menu appears asking you to select the device you’d like to boot from.
This will help us better understand what your system is showing and assist you further.
So bit of an update on my side. I have tried two different branded SSD’s and none result in the Nucleus booting with any HDMI Output. TS256GMTE110S and MZ-V8V250BW. If I remove them from the board (just like the old Kingston one), it boots fine, no issue. So assume something has happened to the motherboard?
Is there a CMOS reset anywhere on these custom boards? or anything else you think may prohibit a normal boot process.
So far, the only workable fix has been to pull the M.2 drive and discard it.
Since the unit is a year out of warranty—and support here in the UK has to go through the dealer—I’m otherwise left with a £2,500 paperweight after just three years.
I created a ROCK USB installer, ran the setup, and allowed it to wipe and reformat my 8 TB SATA SSD (which already contained all my music). After reinstalling the OS, I had to copy the entire library back onto that same drive.
The end result is that both the operating system and my music now reside on a single SATA SSD. I’m not thrilled with this—my Samsung 8 TB QVO is designed primarily for read-heavy workloads, and running the Roon Core on it introduces constant writes (logs, indexes, etc.), which will inevitably reduce its lifespan.
It also means that if I ever want to upgrade the SSD to accommodate more music, I’ll have to start from scratch again. Replacement motherboards for the NUC7i7DNB used in the Nucleus+ simply aren’t available.
That will not be sustainable. And not because of Samsung QVO QLC reduced longevity. RoonOS requires its own boot drive. By design, Roon updates routinely can wipe and overwrite the entire drive. Your up to 8 TB of music storage will be erased.
Based on your description, it does appear to be a failed M.2 controller. I’m glad to hear that you’ve already reached out to our RMA team and found a suitable solution.
I’ll go ahead and mark this topic as resolved for now. Please don’t hesitate to reach out if you have any further questions or concerns.
