Hello mehtizens, I’m searching for help, and hope some member of our community can help me.
I will start by saying I would never encourage or hope to benefit from criminal behavior.
Hypothetically; I’m a current Verizon FiOS subscriber. For the purposes of this thought experiment the relevant facts are:
I am in possession of a set top box registered to a dead man, freely given to me by his sister. His estate has no outstanding balance with Verizon, having already been charged for unreturned equipment. The man’s account no longer is accessible through the Verizon web portal. The box works when connected to cable and a TV. The box only gets the channels and services my deceased friend subscribed to. This hypothetical STB is a Motorola qip7232.
The question I pose is: Can anyone share with me a way to factory reset this box and/or authorize it to my account?
