Need to factory reset some T26, T28and T46 IP phones without admin password
Hello,

One of our customers has been attacked. The attackers managed to place a few admin passwords and change the configuration so a long press on OK asks for the password.

They tried admin/admin and admin/(empty password), all returns as incorrect passwords.

They also tried to unplug the power cable, they kept the OK button pressed down while re-plugging in the power cable, same problem.

So we are stuck for now. Any hint ?

Thanks.
