I still don't think the dish is the problem even with the cable there.
With BH you must upgrade via USB each time but there are two ways to backup and restore your settings.
1 Use Black Hole backup
2 Use software manager to backup
Both work very well, I use the software manager backup and after loading the new image my settings can be loaded straight away, total time to flash a new image and have everything running as it was takes less than 10 minutes.
Let me know how you get on.
Do not download any updates.
catseye, green button > yellow button > download addons > select settings.
go to channel with 0% signal then press
1. Menu
2. go to set up
3. go to service searching
4. go to manual scan
5. go to service scan
then check if the ''inversion'' is set to ''auto'' and finally press ''OK''
it should scan now, hope it could help
cheers
