As I remember, the key sequence to Factory Reset works even with 9951. Try it.

Hi

The factory reset sequence is the same, it just doesn't look like it's doing anything. It's not very well documented either, so it's not clear if it just clears settings and loads up the 'bank b' firmware or whether it actually pulls from TFTP immmediately as the 79xx/69xx phones do.
