root on Sony NSZ-GS7 achieved, fully documented

This is tested and working on NSZ-GS7 REL10 for US

Thanks to the guys with gtvhacker making the temp root. we are now capable of having a static root.

i have now achieved static root, changing the /system

I have used the starting point from entonjackson making the root for Acer A1-810, using dd to seek through the mmcblk0 to write a modified /system :)
see more details on that approach here

the big secret to writing the new filesystem:

0. you need to temp root the nsz-gs7 following the guidelines from team gtvhacker , before you proceed and do the steps below.
1. dump the filesystem: /data/local/tmp/busybox dd of=/mnt/media/usb.E234-1928/system.fs of=mmcblk0 skip=149248 bs=4096 count=1047552
2. on a linux box: mount the dumped filesystem (system.fs) with -oloop to be able to modify it.
3. copy your busybox and suto /system/xbin/ folder
4. umount your dumped filesystem from location you mounted it.
5. write back the newly modified filesystem (i called it system.with_root) .
/data/local/tmp/busybox dd if=/mnt/media/usb.E234-1928/system.with_root of=/dev/block/mmcblk0 seek=149248 bs=4096
