Complete loss of signal
Received my 360 handset. Followed the instructions and it started to up load. After about 15 minutes it crashed with an error message and told to try again. Waited half an hour and started again, When i rebooted it went into an update which ran for about 15 minutes. I was then asked to pair my handset which i did. I then got a message on screen saying my handset had been paired but the screen froze at this point and would not respond to the handset. rebooted, and it opened and stayed on the frozen screen. Looked on the forum and someone suggested switching off, then hold the plus button and the red button, switch on, wait 30 seconds and release the buttons. I now have a 'device has no signal' flag. Rebooted, same again. Any ideas what I can try next
