Multitude of problems

I’m trying to set up the Xumo Flex box. I’m making it through connection to internet. I enter the last 4 digits of my phone number, and arrive at ‘checking your status’, at which point it never progresses.

To try and troubleshoot, I’m attempting a factory reset. The factory reset informs me that I must unpair my remote. That doesn’t make sense, as I still have to click ‘continue’ , but now with what remote?

Ok, so I unpair the remote using + and the back key, then pressing 9-8-1. Maybe it wants me to repair the remote then click continue. Except I’ve now pressed the microphone key for >15s, and the remote isn’t re-pairing to the box.

I’ve checked the forums, and there seems to be no alternative path for pairing.

In summary, I have a remote that won’t pair, can’t factory reset, and can’t get past ‘checking status’ even though I am using the correct PIN.
