How to Root (and Unroot) the Samsung Galaxy Y Duos (S6102)

I.  Before You Begin

1.  Back up everything you feel is important before you begin.

2.  Make sure you have charged your device to 75% or more before you begin.

II.  Necessary Downloads

1.  root.zip 

III.  Rooting the Galaxy Y Duos

1.  Connect your device to your PC using a microUSB cable and copy the update.zip file you downloaded above to your SD card (Do not put it into any subfolders, just the main folder so the path is sdcard/root.zip).

2.  Power down your device and put it into recovery mode.  To do this, press and hold the Volume Up + Home + Power keys until you see the Samsung Galaxy Y logo and let them go after that.

3.  Use the Volume buttons to highlight “select update.zip from sdcard” and press the home button to select it.

4.  On the next screen, select update.zip, and then select Yes on the next screen.

5.  Once the flashing is done, go back to the main menu and reboot your device.

That’s it!  Your Galaxy Y Duos is now rooted!
