Rooting the Samsung Galaxy Android phone

An assembly line issue in Korea means that some phones were shipped with the three button Recovery Mode (Vol Up + Home + Power) disabled. Unfortunately I ended up purchasing one of these neutered phones. To root the phone I had to install the Android SDK and boot into recovery mode. There are more detailed instructions online but very quickly the procedure to root the phone is as follows:

1. Download and install the Android SDK. I installed the x86 version for Mac OSX.

2. On the phone go to Settings>Applications>Development and turn on USB Debugging.

3. Copy the Update.zip (here) to the root of your internal SD card. This is /sdcard on your phone.

4. Connect the phone to the Mac via USB cable.

5. Go to a Terminal prompt

5. cd to /Applications/android-sdk-mac_x86/tools

6. Run ./adb reboot recovery

7. The phone will reboot into Recovery Mode.

8. Use the Volume rocker to highlight the option to apply Update.zip and then hit the Home key. The phone will reboot.

9. Once the phone reboots check for the existence of the Ninja icon with the sniper rifle in Applications. See screenshot below.

A sample of applications requiring Superuser access are:

1. Root Explorer – Allows you to browse protected areas of the file system.
2. One Click Lag Fix – Fixes Lag issues on the Samung Galaxy

Once your phone is rooted and you try to run a program that requires root privileges a dialog will pop up asking you to confirm su access for the application and if we should continue to provide root access in future whenever the application is launched. The below screenshot shows Root Explorer requesting superuser privileges.

Note: You won’t see any files in the data folder if you try to browse using Astro or the built in File Manager as you require root privileges to browse this folder. With a rooted phone and a Marketplace app called Root Manager you will see these hidden files.

    Hi Nicola.

    You can use the Z4Root rooting process instead. It’s a newer and easier process to follow than the one I detailed above. You can find the instructions at the following link below. Also in Step 1 they have a link to the Z4root download file.
