7945 Boot Loop

I have a Cisco IP Phone 7945 stuck in an infinite boot loop.

I tried connecting directly to the UC520, and doing a factory reset.

Goes to the upgrade screen, does nothing, sits there for a minute, reboots. No errors, no Auth Fail message.

Anyone ever experienced this?

Likely somethign si wrong with the firmware files on the UC and yoyu should look there.

I originally thought that might be the issue. Connected the phone to another UC we have in the organization, same problem.

Maybe I should try manually loading new firmware on the phone?

Without look at traces and details, it's impossible to say.

However there are man threads on the same subject that you can search.
