To download the latest software for your Sky / Sky+ /Sky+ HD box, please follow the below simple process:
1) Unplug your box from the power supply
2) Press and hold the backup (on the box, not the remote) button
3) Keep holding the backup button whilst you plug the power back in and until you see a message on the screen saying ‘Updating System Software’
That’s it, although your box should automatically update, this process can sometimes solve certain technical problems.
You should also be aware that sometimes forcing a software update can take you to a previous software release.
