jetpack mhs800L factory reset *without* admin password

[psycodepath]

I bought the mhs800L from a friend for $5. But the range is short and I don't like the SSID. No one knows the admin password or secret question answer. How can I forcibly reset the device? Verizon support was not helpful. The PDF manual wants me to login with the admin password to reset the admin password... really?

the buttons on the outside are not factory reset.
