Hi,

Reset to factory default will clear the config data in the phone.

Hope this will help.

I have successfully reset to factory but am only able to if the phone is not connected to the network. If I attempt to reset to factory and have it connected to the internet the username and password defaults back to the unknown password. Trying to see if there is a setting on the phone I can delete to keep this from defaulting.

This mean the phone is locked to the provisioning server of your telecom provider.
Every time the phone reboot it will be provisioned with a, for you unknown, username/password and that’s why you can’t log in.
Please contact your telecom provider and ask them the username/password or ask to unlock your phone from their provisioning server.

Hope this will help.

Kind regards,
Frank.
