assuming it is a 2700a, just go to where u download ur files, and get the factory bin from there, flash it with that (same way u do a new file), u may have to a couple times, then just put the latest file on it after that.
I am not sure what receiver model you are talking about. Pansat 200A is not a current model. You missed out on one important digit. all current Pansat receiver have 4 digit designation number expet Pansat 250SM. You can look for more info at: [link removed] and many other FTA sites. You can get files without registering at www.currentbins.com
