Here are the steps that a buyer must go through, so as a seller, you need to assist with those steps if you wish to sell your box(es).
1. Call Rogers with the name of the seller and the STB number before purchase. This is to ensure that it's not a rental and is properly in Rogers system (as a third-party STB) and is allowed by Rogers. Have the seller show the STB in operation if possible. This is especially important if it's a PVR because the iHDD could be bad. If they can't demo, then the price should reflect that.
2. Ensure the seller deactivates the STB or tells Rogers they're selling it so that you can then activate it.
3. You must call Rogers when you get the STB home to authorize it.
4. You must have the cable properly connected and a good signal to the STB for it to function/boot.
5. Sometimes another call by the seller is required after the buyer has the STB in his possession and is trying to activate it (due to Rogers Computer issues - there must be some difference between the "check" and the "activate" steps in Rogers' computer system). Sometimes, if you call to activate, and the CSR says the box has not been deactivated, if you know the seller has made the call, if you insist that it has been deactivated, the CSR will often activate the STB without another call by the seller.
6. You cannot use a STB that is not a Rogers Ontario STB (if in Ontario)
7. In the event you wish to incorporate the STB into a WHPVR (Whole Home PVR) setup, a truck roll (service call) will likely be required.
8. Sometimes we get questions about "moving" a STB from one subscriber to another without calling Rogers. This is against the Terms of Service with Rogers, they can find out (monitoring location), and both people could be in trouble with Rogers.
9. Note that there are some smaller Rogers areas in Ontario that utilize Motorola STBs. In those cases you need to purchase the correct Motorola STB(s) and it doesn't have to be a Rogers box, but beware of scam sellers. You cannot use SA/Cisco in a Motorola area, or vice versa.
10. If the seller is not a "customer in good standing" (bills all paid, etc.), then Rogers may have a lien against the STB, so calling Rogers before purchase, as discussed in point one, is very important.
Just to close the loop, Rogers messaged me the following about serial numbers: "If they have the serial numbers, they can add them to their account but that would only make sense if they have the boxes in their possession. Personally, I would stay away from giving out the serial numbers."
Purchasing a Nextbox 3.0
I'm going to purchase a Nextbox 3.0 from someone, are there any fees after I purchase the box to have it on my account?
