i have oscam-emu 11392 installed, how do i upgrade to 11397

stop oscam, download the right one bin file for your receiver architect, unzip it, check in usr/bin directory (of your receiver) what is the name of oscam file (it could be oscam,or oscam-emu,or oscam-11392 etc) rename the new one as the old one, and replace it (for any case,take somewhere a backup the old one).
