Important preparations
1. Fully charge the mobile phone (100%)
2. Disable your firewall + anti-virus software
3. Disable ALL mobile phone manage software (including Samsung PC Studio / KIES or other 3rd party software). Check with ctrl+alt+delete if they are shut down properly

Model I9103 Galaxy R - Android 4.04
  1. Download & install SRS installer and make sure you also install the Samsung drivers!
  2. Now download the software needed for flashing, it's called Odin: click here to download Odin 1.85
  3. Download CWM (ClockWorkMod Recovery) and unpack it on your computer
  4. Unpack the odin 1.85 zip file to a folder on your computer and unzip the kernel zip file you download in the step above in the same folder as where you unpacked Odin. When unpacking your kernel file you should get an other archive file with the extension .tar
  5. Completely Switch off your Galaxy R I9103 (wait for vibration to confirm switch off)
  6. Start phone in recovery mode; hold the power, volume down and the home (OK) buttons simultaneously to start phone in download mode. A Warning! screen should show up. Press Volume Up to continue to enter Download Mode.
  7. Double-click on Odin3 v.1.85.exe to launch Odin3
  8. In Odin3, click the PDA button and navigate to where you unpacked the CWM .tar file. Please select this file
  9. Do not make any other changes to Odin’s settings, make sure Re-Partition is not checked
  10. Connect your I9103 to your computer. On the Odin3 window, you should see an “Added!” message in the lower left message box. This means that your Galaxy R has successfully connected to your computer.
    If this does not happen your drivers are not installed (correctly) and you probably forgot step 1!
  11. Hit Odin3′s Start button to begin flashing CWM to your device

    Important: at this point do NOT touch your phone, do not touch your computer and do not touch the USb cable
  12. When flashing is complete, your Galaxy R should automatically reboot. When you see the Samsung logo, you may disconnect your phone from your computer. You will also see a PASS message with a green background in the upper leftmost corner of the Odin3 window
