Mosaic upgrade causes the Rossini to fail to boot

It stays on this front panel display after turning on (the button does not respond, the blue indicator light does not light up). I tried to restart several times but nothing changed. Why the upgrade process is a disaster and what should I do?

Hi and welcome to the community. I hope that we can help you.

We may have to approach this stage by stage . The first thing to do is ton switch off the unit from the mains. This is not done from the button on the front panel but from the rocker switch on the back panel. Please do this and wait a minute or two before switching back on.

If it then looks like the unit is booting up, open Mosaic on your device ( have you installed the latest version from Play or App Store?) and open the system controls /Support/Versions and check if the update option offers a new update or says that there is no update available.

Please get back to us and let us know how you are getting on.

Thank you very much for your reply.
I turned off and turned on the rear panel power switch after 2 minutes, The front panel display still shows the same startup screen.

Here is the Mosaic App screenshot.




“CHECK FOR UPDATES” button here is not responding


Mosaic can’t find device


I’m sorry that you are having issues with your Rossini after updating your unit - normally the update process is resilient requiring at most a power cycle to complete but of course when updating firmware on any device there is always the possibility - no matter how rare - of something happening.

In this case, if you look in your routers settings has your router allocated it an IP address?

If it has then can you get to the Rossini’s web interface? (If you need help with accessing the Rossini’s web interface then I am happy to send you instructions.)

Thanks Leslie. As Phil of dCS has kindly responded it will be best to deal with him hereon or it will become confused. So start by following his recommendation to check your router.

Hi Phil,
I can accessing the Rossini’s web interface, but the connection seems unstable, disconnect will happen later.
please tell me how to do next if I can see web interface.

Thanks for your help, my friend!

Where are you located geographically?
