Hi again Ste,
I don't understand how everything was lost if you had recordings on both boxes and you only factory reset one box, unless you thought that all recording you made were automatically stored on both boxes.
The Horizon platform (The 360 operating system) which is owned by LG (VM's owners) was originally designed around a shared recording pool, with all recordings made in the cloud. The UK is the only country in Europe that has an actual hard drive for recordings. Because of this the recordings are pooled (shared) and show up on both boxes, irrespective of which box they were made on, even though the actual recording is only made on one box.
As suggested by myself in my previous post all recordings will be made on the one designated main box unless you physically select the other box as the one you want that particular recording (or series recording) to be made on.
The error code CS2004 is usually internet related, and can sometimes be due to loose cabling, usually the coaxial cabling, so best to check all cabling, including ethernet cables if hard wired. It may also be due to a local issue so try running the /check-services/ function for problems in your area. You can also a run a test on your equipment from there.
If nothing is showing you could also try the automated Service Status number 0800 561 0061. This is a better checker as it often gives details of more known local issues right down to postcode level along with an estimated fix time/day.
