Alright so this is an issue we ran into using the Polycom VVX - 401 Phones.
Here is what would happen we had our initial FTP server setup as 18.104.22.16851 firmware.
After inital provisioning when the user would sign into the phone it would prompt them to update. This is where the problem was the update from the Polycom Server would install version 22.214.171.124xxx.
126.96.36.199xxx is not an available version you can download for an FTP server is it slightly behind the lowest Stable build of 188.8.131.5251. So when the phones would try to reboot and search for the files matching 184.108.40.20648 you could see in the boot log that they could not find the files, because they were looking for an older version than the FTP server had.
Also it did not matter what version the phone was on 220.127.116.1151 - 5.9.1.xxxxx it would always update is the user chose to update down to 18.104.22.168xxx. After this point anytime that phone would be rebooted it would go into that Downloading Core 1 of 1 loop which I'm sure some people are familar with.
The fix to this issue and to stop the Core loop crash is to make it so phones do not seek updates from the Polycom server.
IF YOU ARE STUCK IN Core 1 of 1 download loop. The only fix is to factory reset the phone using the keypad (factory reset option). This might help you save a few phones that seem stuck in Limbo.
This will force the phone to use the provided FTP server and it will not communicate with the Polycom FTP server.
Add these two lines to an exisiting .cfg file (Do not enter line 1 or line 2 they are for reference it can be anywhere in an exsisting cfg file as its own entry.)
<DeviceUpdate device.set="1" device.prov.lyncDeviceUpdateEnabled.set="1" device.prov.lyncDeviceUpdateEnabled="0" lync.provisionDeviceParams.enabled=”0”>
line 2 </DeviceUpdate>
Or create a .cfg file with the following single line entry. (The change is the / before the final >)
<DeviceUpdate device.set="1" device.prov.lyncDeviceUpdateEnabled.set="1" device.prov.lyncDeviceUpdateEnabled="0" lync.provisionDeviceParams.enabled=”0”/>
Hello @LRose ,

Resolution: A core dump is uploaded by the phone if a phone crashed for some reason. Please provide these to Polycom support for further analysis.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Both of your solutions are correct but users/admin might not realize that the firmware download is the issue. What people seem familiar with is downloading core 1 of 1 repeat which I have seen multiple articles on. So I posted our solution to the issue when we found what it was.
Hello @LRose ,
you did not supply the full firmware details so I cannot comment but I assume you are mentioning a Microsoft hosted Firmware.
Not knowing these full details makes it difficult to comment on a post.
