For a number of month I have been experiencing problems with my BT Ultra HD box.
On numerous occasions when i switch on the box I am prompted to perform a Software Reset or Factory Reset.
After performing the software reset the box will switch but I bo not have any Intrenet channels or catchup.
The only way I can get the channels back is to perform a Factory Reset, this is not a very good option as I lose all the recording settings.
As this is now happening every 2 weeks it has become very frustraing as recoordings series is very painful.
The is a corruption with the box software.
Have you tried maintenance mode option Internet/USB and keep recordings?
If after this you still have issues you need to call BT help and ask for a replacement
I have tried maintenance mode. This fixes the fault and gets the box working again but it continues to happen on a regular basis.
Sorry to hear you are having issues, would be happy to discuss these with you and help resolve them if you are able to contact me directly with your details. Just send me a private message.
