I have a 7975 which i keyed up a factory reset on. it goes to the upgrading screen, then goes to load term75.default.loads, comes up with an Auth. Fail, and then instantly tries the exact same file once more on a new screen. (the two screens come and go within couple of seconds) Then it goes to the Cisco splash screen and sits there for ages with a circle symbol in the corner which has a dot in the center, then reboots, then over again. I have tried to change it to load SCCP75.8-5-4S.loads in telephony-service, and that file has also been tftp-server-flashed, but everytime I reboot the phone it does the same thing. Have I missed anything?
Here is the output from TFTP debug:
Apr 4 12:25:13.989: TFTP: Looking for term75.default.loads
Apr 4 12:25:13.989: TFTP: Opened flash:/Phones/7975/term75.default.loads, fd 10, size 654 for process 380
Apr 4 12:25:13.993: TFTP: Finished flash:/Phones/7975/term75.default.loads, time 00:00:00 for process 380
Thanks!

That happens because term75.default.loads uses a version that is too new for the phone to update to (search "auth fail").
Give it a correct term75.default.loads version, have it update, then update again to a newer version.

Hi Paolo,
Thanks for your fast reply. Is there any way I can find out what version it is requiring? The phone came from a different system and is now on ours, so I am unsure as to which version of term75 it wants. It could even need a firmware downgrade and not an upgrade, correct?
Thanks!
Nic.

As Rob mentioned below (rated).
8.5.2 is currently free from excessive enforcements for download.

Hi Nic,
Paolo is most correct here (+5 "P" )
TFTP - Auth Fail shows on phones (they must be @ 8.5(2) before moving
to the 8.5(4) you have loaded. So you need an interim version as a first step.
Firmware Upgrade Issues for SCCP
Note For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(3) or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(3) or later.
Cheers!
Rob
Note: make sure to use the base 8.5.2 not 8.5.2sr1
