You’re more than welcome to return the dongle. I will test it upon receipt and check if it is indeed faulty. Regardless of whether there’s an issue, we can certainly issue you with a refund.
Fortunately I was able to work on DVB today and I’m now happy to say that support has been added for DVB-T2 for the OSMC dongle. This gives you Freeview HD in the UK. If you’d like to try this before returning, do let me know.
You may be able to use your other dongle for DVB-T2, but we can’t guarantee this compatibility with other devices. There are thousands of devices out there; but we will do our best to support other chips.
Development was for the OSMC dongle in mind. It would be interesting to see how you get on using this device. If you do keep the device I can raise a credit on your account towards a future order.
Cheers,
Sam
