Full root on Samsung Galaxy without NPS

July 30th, 2009

It works and no need! of the f***ing NPS.

WARNING: All doing on your own risk!!! If you did not understand what the commands do, do nothing. Beware, if you flash the flase image you got a stylish brick!

Steps to do:

a) flash the modified recovery i describe here Root for adb on Samsung Galaxy

b) download a working su from or direct from

unzip the file.

c) boot in recovery mode and start adb on your desktop, next copy su to your phone

adb push su /tmp/su

d) follow the intructions:

adb shell

mount -o rw -t yaffs2 /dev/block/mtdblock1 /system
cat /tmp/su > /system/xbin/su
chmod 6755 /system/xbin/su

Final: After reboot start adb on your desktop and type these commands

adb shell


If it looks like this you have root!

$ id
uid=2000(shell) gid=2000(shell) groups=1003(graphics),1004(input),1007(log),1011(adb),3001(net_bt_admin),3002(net_bt),3003(inet)
$ su
# id
uid=0(root) gid=0(root) groups=1003(graphics),1004(input),1007(log),1011(adb),3001(net_bt_admin),3002(net_bt),3003(inet)

If it works write a comment please. If it not work also write a comment please, and put the errors to them.


Mounting the system partion breaks the recovery image to start. So after doing all the steps reflash the recovery image!

    Can you provide a link of the stock samsung recovery image?

    Just realised I can’t after flashing the custom recovery image. I need the image for factory reset.
