- Extract the rooting file the same way so you can see it on the desktop and leave it there.
- Completely shut down the Galaxy Alpha by holding in the Power button for 10 seconds.
- Reboot the Samsung Galaxy Alpha in Download Mode .
- Now connect the Alpha to the same Windows PC you are using with the USB cable.
- Click the PDA button inside Odin and browse for the rooting file on the desktop. It is the one with the same file extension that’s shown in the link above.
- Click the start button inside Odin and the app will now root the Samsung smartphone as long as you do not remove the connection.
- You’ll eventually get a pass or fail message and the Samsung Galaxy Alpha will reboot itself. That’s when you can unplug the handset and take control of your Google account once again.
Those with the fail message probably need to install the USB Drivers. Reboot the PC after installing the drivers so the drivers are working.
