Call Manager 10.5.2

The majority of our 8851 phones when plugged in will upgrade from sip88xx.10-2-2-16 to sip88xx.10-3-1-20. however a few will not. They will have this in phone configuration -

Registration: Registered with Cisco Unified Communications Manager cucm2.ad.churchmutual.com
IPv4 Address: 10.XX.XX.XX
Active Load ID: sip88xx.10-2-2-16
Inactive Load ID: cert.os.mfg.drop
Download Status: Upgrading
Requested Load ID: sip88xx.10-3-1-20

Phone information display on the phone will say "Upgrade failed".

I have tried factory resets on these with no effect.
