Hi.
First, check if any packages containing the text "cam" are installed:
opkg list-installed | grep -i "cam"
If so, then you uninstall the packages you don't need (OSCam packages):
opkg remove <found_package_name>
Note: The name of the package you use must exactly match the name of the installed one.
If there really is no package under the installation manager (under the opkg), then you probably installed / changed something manually. In this case, delete the "init.d" scripts, which contain the OSCam process handle (primarily, this ensures that the process is started during Linux booting). Then check if any OSCam(s) are running (scroll and find them, for example, with the help of the top or htop tools). If you found any running OSCam, kill them directly in the top (htop) tool or with the command: killall -9 <process_name> . Finally, delete the OSCam binary files, belonging to OSCam, in the /usr/bin folder via FTP connection or manually.
