At present there is a 2S version which will also do your box. It is on the list of boxes still to be done. When done you will be able to flash 7 and make your changes. I will get it done asap.
@Jim1088 - Yes you can use the same line on the second box but for both to work the line would need to be multiroom. Most line providers had this set as standard but I know there were a few providers where multiroom lines were extra. If this is the case you won't be able to watch both boxes at the same time.
@deak205 - The SkyQ skin is already available in the skins section of downloads as it always has. The new version by Chabs will automatically replace the current version and will show as an update if you have the current SkyQ skin installed.
