Normaly when you want to upgrade or change your image you shoud do a backup of all conf.files by default.And then first install cccam and oscam emu from addon server,find one in section "emu for open pli image".After install make enigma2 restart.Then connect to your box with some FTP program(i use total comm.),and go to "usr/etc path.Now if there is cccam.cfg file delete it,same way is with oscam,go to etc/tuxbox/config and delete all config files that came with emu installation.When you have done all of this put your conf.files (cccam on usr/etc and oscam on etc/tuxbox/config path.).
