How to backup / partition before rooting? I would like to root my Nexus 5 but I am worried it will cause a bootloop or some other sort of problem and therefore I would like to back up all my phones data including / before hand. Is this possible?I have already tried using the adb command like this:


  adb pull / your path here


But this doesn't work and returns


  permission denied: read only file system


Is it possible using adb to backup / without having to be rooted so that I can root?

Thank you,

Isaac

Is there any way I can use adb pull instead of adb backup?
You do not have to backup Entire /. Rooting phone only unlocks bootloader for custom recovery and involves installations of the su binary in /system partition and the overall partitions that can be affected due to bad root are: /system, /data, /cache. Rest of the partitions wont really be bothered.

An effective way to backup your everything is to use ADB Backup. It will backup ALL of your data except SMS (so backup them up manually with some app beforehand).

Hope this helps.
