  • The requirement for a rooted device and a custom recovery is never going to go away: if you don't have root access, then you have no means to copy the entire contents of your device's memory, simple as that.

I have written some tools for exactly this purpose, due to similar frustrations: https://github.com/dlenski/tetherback

These tools are written in Python and use adb to create either nandroid-style backups (raw partition images from dd if=/dev/block/mmcblk0pXX) or nandroid-style backups (mixture of raw partition images and tarballs for ext4 partitions).

They attempt to probe the correct partition layout, and show the progress of the backup:

$ ./twrp_backup.py
Device reports TWRP kernel (3.4.0-bricked-hammerhead-twrp-g7b77eb4).
Reading partition map for mmcblk0 (29 partitions)...

This is a work in progress—feedback is very welcome!
