Before You Begin

1. Make sure that you have backed up everything you feel is important before you proceed.

2. Charge your device to more than 75% before you begin.

Installing ClockworkMod Recovery on the Galaxy R

Files :

1. cwm_4.0.0.2_for_i9103.rar

2. Odin 1.85.rar

1. Power down your device.

2. Press and hold the Volume Down + Home + Power buttons until your device enters Download Mode.

3. Extract cwm_4.0.0.2_for_i9103.zip to a folder on your desktop. You should end up with two files called cwm.tar and cwm.apk.

4. Extract the Odin 1.85.rar file you downloaded above to a folder on your desktop.

5. From the extracted folder, double-click on Odin3 v1.85.exe to run the tool.

6. Click on PDA button, locate cwm.tar and click on OK to load it on Odin.

7. Connect your device to your PC using the USB cable. Odin should now recognize your device and light up the ID:COM field yellow to signify this. If not, reinstall the proper drivers and try again.

8. Make sure that the Re-Partition and Flash Lock are unchecked; this is important as you might brick your device if these options are ticked!

9. Click on Start.

Once Odin says PASS and your device reboots, you should have ClockworkMod Recovery running on your Samsung Galaxy R!
