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

[sashank]

HI,

 

I am attaching a document which will explain you the recovery procedure after doing  a factory reset. Remember that this process will be usefull if you have no choice other than connecting your Phone to the System and upgrade using TFTPD32. I searched for the procedure. Couldn’t find much information. So thought of creating this document.

 

Warm Regards,

Yes, I was worried this was coming into play here, but thank goodness I was able to downgrade after the upgrade.

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.

Cheers,

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.

HTH
