I assume that you saw my original answer????
It would help if you say if your box is a Sky branded box? (As I asked before) and what you are trying to achieve? Because your question doesn't make much sense. For example "the box reverts back to original frequency".
If you are trying to watch Sky programming on Astra 28.2 on a Sky box in Spain you do not need to do anything to your box. It will just work.
If you are trying to add programs that are not part of the Sky EPG then they will never appear on the EPG because the box doesn't work like that.
