Hello mido.fayad,
I have installed Multiboot and Backupmenu according to your page 1. I have tested and backed up rootfs and opt.

I would like to add Power kernel and test it before I eventually install Nitdroid.

I have the need to go slowly because I have never broken or flashed my device and like to keep it that way if I can.

Have done that OK,
