Problem with coping mmcblk0 to pc I want to clone internal memory of my android phone. Version 5.0 lolipop.
I have found an tutorial website but this is not working. Web site link given below.

chmod +r /dev/block/mmcblk0 returns Bad mode

shell@M1:/ $ su
root@M1:/ # chmod +r /dev/block/mmcblk0
Bad mode
10|root@M1:/ #

and adb pull /dev/block/mmcblk0 "mmc.img" returns

adb: error: failed to copy '/dev/block/mmcblk0' to 'mmc.img': remote Permission denied
To copy mmcblk0 or any partition directly to pc, you need root access and busybox installed on your android phone.

Working ADB command is adb -d shell su -c busybox dd if=/dev/block/mmcblk0 bs=4096 &gt; D:\mmc.bin
