This is an old thread from 2014. Now there is an image named OpenBlackHole that contains the C band blindscan. You may use the OBH image instead of transferring the files to the Black Hole image.
To Install:
1. Unzip and remove the bin file folder from the blindscan folder.
2. Install the install the blindscan folder using FileZilla or other ftp to:
usr--->lib--->enigma2--->python--->Plugins--->SystemPlugins
or
/usr/lib/enigma2/python/Plugins/SystemPlugins
