To clarify a backup image as all my settings only thing to do is FTP your n/c line into correct folder then set your region for autobouquet. I install minimum plugins so image stays stable.
I use DCC, FTP password is pkteam, navigate to keys folder and ftp your c line or n line to correct folder. Then PKT blue panel and emu manager to activate EMU you used. Good practice to save your camd.list or newcamd.list or oscam.server file to make easier when changing images just ftp them in saves lots of time.
Please note use SPARK and E2 upgrade tool to flash image.
