Cisco 7971 - reboot loop upgrading... failed

[cyberhostpro]

Hi

I got a Cisco 7971 refurb today, i read online to reset the config hold # during boot and enter 123456789*0#  which rebooted the phone.

Now it boots up and shows upgrading screen, then says error and reboots itself.

anyone know how i can fix this?

Hi

i've downloaded 8.5.2 so thanks for that. i extractracted them to a new folder called c:\firm and set my tFTP client to point to that folder. 

I then rebooted the phone, it downloads the term71.defaults.load then reboots. then upgrading comes back on screen and says failed, then adds to the log another download of term71.defaults.load as shown in screen shot.

I have experienced this before..It just tells you that you have the wrong firmware (ie the phone cant upgrade to that firmware) for the phone on the tftp server. Can you try using 8.3 firmware..Download that to a tftp..Make sure that you extract all the files including term71.defaults

Hi

each 8.3 firmware i try to download on the cisco site says this:-

Cis is causen real trouble with these restriction in places.

They require a valid support contract to downalod images, then the absurd thing sis that many products are EoL already, and no support contract can be purchsed anymore.

I can only suggest again, for SIP service at home, use something else.b

Its not for at home its for office use with our PBX which is asterix.   I've bought these phones and they were not just cheap throw away prices I need to get them to work.

Do you know anywhere I could find a copy of these files?
