Sigh, THE GUIDE IS NOT AVAILABLE ON ANY BOX OTHER THAN THE AMSTRAD 890 OR 895 1TB BOX.
That is, ANY box made by Pace, Samsung or older Amstrad boxes CANNOT get the guide by forced update at the moment as it has not been released yet. You can do as many updates as you like but it won't happen.
The guide will NEVER be available on any Thomson box.
Explains why it didnt work on the Sky HD box I gave to my brother last year.
I noticed the one I brought which the update worked, the box looked different on the front as it had a green LED and Sky 3D Anytime+ logo on the front.
