default username/password not working after firmware upgrade

[tfrohling]

I have several T20P phones and wanted to make sure that I was running the latest firmware so went to the download area and downloaded the 9.61.0.148 firmware upgrade. I uploaded that to two phones and realized that after doing this the default admin/admin username, password combination no longer worked. I'd happily drop back to 9.61.0.85 but, now can't get into the phone to do that. In addition I now notice that tcp port 12345 is now open on the phone, whereas on the phones that have not been updated, only have 80 and 443 open. Is there a way to use some program or utility that will allow access to the phone on this new open port?

The phones that have been updated, still function fully as extensions.

Thanks to anyone who may be able to help access the phones for updates or feature changes through the web interface.
