Just to make sure, it's a downgrade from 8.3.3 to 8.0.4. The only line 
changed in the SEPxxx file is:

from
<loadInformation>SIP41.8-3-3S</loadInformation>

to
<loadInformation>SIP41.8-0-4SRS2</loadInformation>

Nothing else changed. When I power the phone down and up again, the only 
thing it does is going into the upgrade screen, getting an IP from the 
DHCP server and then say "Upgrading". In the tftpserver logs I can see 
that it does not even pick up the SEPxxx file.

I haven't checked the phone's web interface. Frankly I wasn't aware that 
it was active during the upgrade process. I did try telnet and ssh but 
both were unresponsive. Will try the web interface when I'm near the 
phone again.

Thanks,
Patrick
