Help needed with deleted transponder on openbox s10!!!

Was trying to work out last night, why some channels work with some servers and others not with the same server.
As some channels are double, they will only work with particular servers.
While looking into this accidentally deleted 1 transponder (God knows which one as over a hundred)
I now can not scan *** Premier 1, +1 and no doubt a few others.
Have tried a few things, ie factory reset, this has not worked.
Do not want to load a channel list as some double channels, I may need for different servers.
Any ideas how can get the transponder and missing channels????
Many thanks

Khan when you say you can't scan these channels, how do you mean? Is there no signal on the transponders ofvthe channels you deleted?

Apolgies chaps, this was resolved yesterday and totally forgot to add a post here.
This is what I did manually entered the transponder which was 11836 27500 H
Scanned this and got channels back.
