[cisco-voip] factory resetting a 7942 - stuck on "upgrading"

[Nicholas Samios]

I know this particular issue is resolved and this may not be entirely relevant…but I’ll post it anyway as it helped me fix an issues recently ☺
Cisco changed their signing authority used on device firmware recently.
Phone’s with a firmware 8.3(2) or earlier must be updated to one of the ‘bridge’ firmware releases, being 8.3(3) <-> 8.5(2) which understands both signing keys.

If you try to go from 8.3(2) or earlier directly to 8.5(3)+ it will die citing ‘auth fail’ on the phone during boot/load.

Hi

I have had the same problem recently with 7975, which I did a factory reset and during boot it stuck exactly at the same screen of what you have posted.
I did a debug on CME with " debug tftp events" and found out it was looking for the load file which came along with phone which has 8.3.2, since I have upgraded the phones with firmeare 8.5.x, it was not booting.
I had to download old files from Cisco site and loaded the OLD files to the phone, it booted promptly, without issue, once it boot I have upgraded it with latest firmware.
