I was able to save the contents of eMMC as an *.img following this link http://elinux.org/BeagleBone_Black_Extracting_eMMC_contents <http://www.google.com/url?q=http%3A%2F%2Felinux.org%2FBeagleBone_Black_Extracting_eMMC_contents&sa=D&sntz=1&usg=AFQjCNGM_Ak68pR603ZNyLkvVfB48DSN2A> , into 4GB FAT32 uSD card, no button pressing. After that I modified autorun.sh as per instruction from the same side. The restore on the same board doesn't hapen, however. Any hints? Jan
