How to make a full backup image of your Android device, assuming it has TWRP installed:
# Just copying the main block device, byte for byte
adb reboot recovery
adb pull /dev/block/mmcblk0 mmcblk0.img
# Or, you could make tarballs of the /system and /data partitions.
# You can see what the device mappings are by doing: adb shell cat /etc/fstab
# So, for my device, I did:
#!/bin/sh
adb shell mount -r /system
adb shell mount -r /data
adb shell 'stty raw; tar cpf - /system 2>/dev/null' | pv > system.tar
adb shell 'stty raw; tar cpf - /data 2>/dev/null' | pv > data.tar

If you don't either do adb shell 'stty raw; tar cpf - /system 2>/dev/null' | pv > system.tar, or adb shell 'stty raw; tar cpf - system | pv > system.tar, the tar will get corrupted because the it will insert at the start of the file:
tar: removing leading '/' from member names
