preloader is the jaicrab tool to backup and restore flashes. just set advanced.cfg to backup your NOR, put the lv2diag.self that came with advanced.cfg and start the console. oh, and make sure you set in the cfg to shutdown and not reset. and watchout for the restore option, leave it disabled , only enable the backup option (Backuprflash.bin).
after that, check it with HxD, which is an hex editor, in the points i've said to check
