[TriLUG] unlocking a sonicwall firewall?

[Carl Crider]

Hello,

 We have a couple of left-over firewalls that we may want to use this year.
They need to be unlocked, or flashed in order for us to use them. Anyone
have experience with this? They are Sonicwall TZ170's

 These were replacements from a large un-named bandwidth provider, and
the service tech just gave them to us. I have had no luck googling for this
info.

Thanks,

Carl
