Next step is the Desaster-Recovery check. On the 1st partition on the harddrive there is the file "BOOT.PRF". This file contains a boot counter that is increased on each boot attempt by the IPTV Bootloader. If the BOOT.PRF file is not found or if the boot counter is at least 4, then a Desaster-Recovery is triggered. | Next step is the Desaster-Recovery check.
