For those of you who have a Samsung Galaxy R I9103 and have been wondering about how to root your device, look no further. Thanks to XDA Developers forum member legion1911, it’s now possible to flash ClockworkMod Recovery to the Galaxy R via Odin, and to root the Galaxy R by flashing Superuser from Recovery Mode. The process is quite easy, even for users who are completely new to tinkering with their Android devices.
“Rooting,” “getting root,” or “rooting your phone” is the process of modifying the operating system shipped with your device to grant you, the user, complete control over it. This means that you can overcome limitations that carriers and manufacturers put on your device, extend system functionality and even upgrade it to a custom flavor of Android.
Rooting takes only a few minutes, keeping your stock OS intact. After the process is completed, you can start installing custom ROMs and fully enjoying the functionality of your device.
Make sure that your device has a charge of at least 70% to prevent it from shutting off in the middle of the rooting process.
Rooting the Samsung Galaxy R
Once you have all of the requirements, you may now proceed to the rooting process.
Extract the contents of the ClockworkMod Recovery package into a folder on your computer. You will find two files: cwm.apk and cwm.tar.
Copy the Superuser ZIP file to the root of your phone’s SD card.
Launch Odin on your computer.
Under “Options” in Odin, make sure that “Repartition” isstyle=”text-decoration: underline;”>notchecked.
Click on the PDA button in Odin.
Choose the cwm.tar file which you extracted from the ClockworkMod package.
Turn off your phone.
Reboot it into download mode by holding down the Volume Down and Home buttons together, then pressing the Power button.
Once the phone is in download mode, connect your phone to your computer via the USB Cable. You should see the device connected to Odin and the ID:COM field will turn yellow, indicating that the device has been recognized.
Hit the Start button in Odin. The software will flash the recovery image and your phone will reboot.
Unplug your phone from the computer.
Turn off the phone and reboot into recovery. You can do this by holding down the Volume Up and the Home buttons as you turn the phone on. Let go of the Power button once you see the boot splash screen.
Once you’re inside recovery mode, make a Nandroid backup of your phone.
Then, navigate to “Install Zip from SD Card” and select “Choose zip from SD card”.
Select the Superuser zip that you copied to the phone earlier.
Once the file is flashed, reboot your device.
Congratulations! Your Samsung Galaxy R I9103 is now rooted and also packs ClockworkMod Recovery.
