VVX 500 reboot loop

VVX 500 reboot loop

I'm a home office user that has been using the vvx500 on my own.  It is not a deployed solution within the company.  I figured out how to get it to work with our Skype for Business server and it has worked well over the last year.  

Yesterday I tried to upgrade to the 5.7 version of the UC software and it is stuck in the bootloop.  I get the error about the config file not found.  I tried to reset the phones settings but it's still stuck in a loop.  

I have no support so looking for some help from the community.  

I've entered setup on the phone.  Can someone send the polycom upgrade server parameters so I can try the upgrade again?  Any other idea's? Any idea why it wouldn't have worked?

I've upgraded this mutliple times and never had an issue.

Hello @MH30092,

welcome to the Polycom Community.

The best solution would always be to setup a local provisioning server as explained here:
