Any suggestions for setting up a new TiVo Mini VOX to connect to a Roamio Pro running TE3? Having spent the better part of 4 hours on the phone with TiVo support, with the Mini VOX stuck at the V70 error unable to find a host DVR, I'm exchanging it with Amazon for a new Mini VOX. TiVo's assertion is that the box is defective and needs to be replaced by Amazon, since it was purchased from Amazon. I'm not the most hopeful that the new one is going to work. I have an existing Roamio Pro and older Mini, both from December 2013 running TE3 with no desire to update to TE4. Verizon FIOS service, using the Verizon Quantum Gateway (new in 2018) to create a MOCA network. The existing Roamio and Mini both work fine, connect to each other and the Internet. Hooking up the new Mini VOX, it connects to the Moca network fine, connects to TiVo for account and download in initial guided setup. Both new Mini VOX and TiVo website reflect the same changed device name. But, then after that's done, it goes to the V70 cannot find Host DVR error and never gets past it. Rebooting the Mini VOX stays in this endless loop forever, repeating guided setup and stopping at the same spot. Over the course of those hours with Support, they had me do repeated Network Connections from the Roamio, reboot the Roamio, reboot the router, and they confirmed that they could see the new Mini VOX. They confirmed that the Mini VOX was running TE4. But, they were expecting it to see the Roamio and prompt to downgrade, which never happened. On the first call, they said they would push the TE3 software to it and to wait 3-5 hours and call back. But, after those hours, it was still on TE4. The only solution offered by support was to return it to Amazon and get another one, saying this one must be defective. Each time they said this, it definitely seemed like they would have preferred I bought directly from them. There was nothing they could do directly, and stated that Amazon would need to replace it under warranty. Beyond being super mad, and now needing to wait 3 days for the new unit to arrive and repeat all of this, any suggestions on steps to do differently? Or, things to check? Ideally, I don't want to change to TE4, stuck in my ways and happy with TE3 just fine. PS: The Amazon call took all of 10 minutes, they immediately gave me a return shipping label and ordered the new unit.
