Describe the issue

Hello. Over the last few days, I have made numerous attempts to connect to Nuleus (via the Roon app on my smartphone and laptop). The device suddenly stopped playing and it was no longer possible to connect to Nucleus (it was also no longer visible—neither in the app nor on the laptop). I then reinstalled the app several times and deleted the cache and everything else. Without success. I tried restarting, disconnecting from the internet, rewiring, restarting, etc. None of this worked. I unscrewed the Nucleus and disconnected it from the internal battery for 20 minutes (according to your instructions on the internet). That didn't help either. When I run Roon on my laptop, I can see my laptop in the Roon app. However, I can no longer find the Nucleus (the device is powered on, the LED is lit, and so is the LED on the Wi-Fi cable). I then connected a monitor to the Nucleus' HDMI cable and the word “ROON” appeared on the screen. I could move the mouse, but I couldn't reboot or do anything else. It seems as if it can't connect to the network/is no longer recognized. The serial number is SN54B**38B9***.
I hope you can help me, because I would like to enjoy music again.

Hello @MouseMusic ,

Thanks for reaching out. Seeing just the Roon logo on HDMI output typically indicates that the M.2 SSD has failed and needs to be replaced. We can help walk you through an SSD replacement and operating system reinstall and that would be the simplest option, or depending on your location you may be able to get serviced by our US based service center or a Roon distributor in your country. Would you be willing to replace the SSD yourself? Let us know how you’d like to proceed?

[MouseMusic]

Thanks for your help. Yes, I would like to proceed and do it by my self (located Europe).

By the way, I installed a hard disk myself to expand the storage Space. I disconnected it. But you dont mean that one, do you?

[MouseMusic]

I got it. I need like the M.2 SSD wich holds the roon database only, not music files. Should I order one? (TS256GMTE110S)?

Hello @MouseMusic ,

Perfect! Note that you’ll need a USB drive for this process that you can connect to a computer, and then the Nucleus.

The first thing you’ll want to do is purchase a new SSD. Here is a link to one SSD option we recommend to many users:

Amazon.com: Transcend 128GB M.2 2280 SSD, Up to 1,500 MB/s, Compatible...

And here is a short video on how to replace the SSD on your device: Nucleus SSD replacement.mp4

After that, you’ll need to format the SSD. We have a good help article you can find here for next steps. Start from step #3 :

ROCK Install Guide

Essentially, you’ll be flashing the ROCK OS to a USB drive, and using it to boot and format the new SSD in your Nucleus.

Once you’ve successfully flashed ROCK onto the new SSD, keep your Nucleus online and complete the form below:

Nucleus Troubleshooting

From there, we can update you to the Nucleus OS on our end.

I’ll be on standby for any questions you have in the meantime!

[MouseMusic]

Hey thanks. I habe the new SSD installed. You mentioned the process for ROCK and Nuc.

• For NUC 12 and older: Your device is supported by Intel.
• The exact model number is printed on a sticker on the bottom of your NUC.

I have a nucleus + from 2019. Wich Software should I download to flash the System? Intel?

Thanks!

Hello @MouseMusic

Thank you for the update.

You can skip the step with the BIOS update. Feel free to start from Step 3 of the ROCK Install Guide provided by @noris earlier.

[MouseMusic]

Thanks, do I also have to do step Nr. 6 of the ROCK Install Guide provided by @noris earlier?

[MouseMusic]

I made it thru!
I see now my “roon optimized core kit”.
All the System Status’s are ok.
But it say I have to “Update required”.

Can someone please help with the next steps?
I cannot connect via the “connect” Button.

[Suedkiez (Just a fellow user like you)]

The Nucleus software is up to date, build 271 for Roon OS and 1582 for Roon Server.

Where does it say „update required“, in the Roon app? Can you go to Settings > About and make a screenshot of that?

[MouseMusic]

Here it says that: I try to connect via Android-App from Mobile Phone

[Suedkiez (Just a fellow user like you)]

That’s weird because the version numbers on the screenshots are up to date. (And also weirdly, this „Update required“ text wasn’t there in the first screenshot you had posted previously.)

One thought: Is your Android app the regular version, i.e., not the Beta version? If it’s the Beta, switch back to the regular one.

If your Android does have the regular version, you can try „Select a different Roon Server“ in the second picture, it should list all Roon servers it can find, including the ROCK again. Maybe then it lets you connect.

If not, I suggest waiting for official Roon support when they come back from Thanksgiving next week.

Hello @MouseMusic ,

Thanks for your patience as we returned from Thanksgiving break. @Suedkiez appears to be correct, it looks like you are running Early Access on your Roon remote devices. To be able to connect to the Nucleus, please try to uninstall the current version and reinstall the latest Roon version avaliable from the Play store. And if you haven’t already, please submit a request to our team to flash the Nucleus back to Nucleus OS, as the specific thermal heat management capabilities is tied to the Nucleus OS and is needed to ensure long-term stability.
