9508 Not booting on 9.0 system 2

I have been using 5420 DS sets and I am having trying to switch to 9508 DS sets but I am having a problem with adding 9508 DS sets to a 9.0 system.

The handsets will light up then get stuck on PLEASE WAIT. Is there a file that I might be missing in Manager or in Embedded File Management/Primary or an upgrade I need to get them to work? I see that the 9508s are suppose to work on 9.0.

Thank you
 
It's been a while since I've used digital phones.

I would get sysmon running and enable file system, TFTP and HTTP filters. That should show you what the phone is looking for. You may have to reboot the system to get the phone to try the upgrade again.

I wonder if the phones might have newer firmware and aren't allowing a downgrade to the firmware that is used on 9.0
 
@biv34ei that was my first guess also. Sounds like the firmware is too new
