Poly X Series - LEDs flashing White / Units unresponsive

[SR_MCSE]

I had a number of my X30 and X50 devices, 10 of 15 units, that were showing a health status of offline in the Teams Admin Center and would not respond to a reset from the WebUI. 

I have multiple units on the same floor, and some were impacted and others were not. 

Their paired TC8 tablets were not impacted by this event.

My only means of resetting these X series devices was to run around to the rooms and pull power and plug back in. 

After a reboot they came back online and were functioning correctly. 

In the TAC, I find it odd that it states there is an 'upgrade' available for the X series, however it wants to bring it back down to 3.13.0.368067 from 3.14.0.372034. The consoles show healthy and show 3.14.0.210851 is up to date. 

I have all devices running 3.14.0.372034 and have been on this version for just over 3 weeks. 

From the user guide, it states:

Pulsing white

Boot initialization in progress

What would cause this to occur and get stuck?

Hello @SR_MCSE ,

Welcome back to the Poly Community.

The LEDs mean the Android software has rebooted / crashed but is not starting up successfully. Please raise this via our support organization and provide the logs prior to a manual reboot if this can be reproduced or happens again.

If you open a ticket please mention as an example 34363431 so it can be escalated in the region.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
