- Verify that the correct USB drivers are installed for the phone on computer (download Samsung Galaxy S3 I9300 USB drivers).
- Back up important data and settings on the phone by using one of the recommended custom recovery tools such as ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup.
- Make sure that USB Debugging mode is enabled on the phone by navigating to Settings > Developer Options (if the device is running on Android 4.0 or later) or go to Settings > Applications > Development (if the phone is running on Android 2.3 or earlier). Otherwise, if the device is running Android 4.2, then perform the following steps:
- Go to Settings > About Phone
- Scroll down to the bottom of the screen and select Build Number
- Tap the phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings. Then select the checkbox to enable USB Debugging mode under Settings > Developer Options.
- Ensure that the phone has at least 80 percent battery charge.
- Allow the newly installed ROM to stabilise for about five to ten minutes before working on it.
- Double check to see that the device is factory unlocked and rooted with ClockworkMod recovery (CWM) installed on it. Root Checker app may be downloaded and installed on the phone to verify if root access is working correctly, before proceeding with the custom ROM installation.
