Thanks Terence for a great blog!

I too have a RC8221 which was locked to my service provider (Elisa in Finland). Factory reset went ok, and I got to the admin panel.

Unfortunately administrator as username (password empty) doesn't work. Is it possible, that credentials might be hard coded or flashed in firmware?

Do you have any hints to give how to solve this problem?

Cheers!
