• Android 4.2.2 Revolt JB ROM and the instructions given in this guide are applicable to the Galaxy S2 I9100 model only and will not work on any other device. Verify your device's model number by navigating to Settings > About Phone.
• Verify that the correct USB drivers are installed for Galaxy S4 on your computer (download Galaxy S2 I9100 USB drivers)
• Back up important data and settingson the phone. It is recommended to use one of the custom recovery tools such as ClockworkMod (CWM) or TWRP for data backup, as it creates a backup with complete image of your current phone setup.Avoid using Samsung KIES or ROM manager, as they lack flexible options for data backup and may cause issues with the newly installed firmware.
• Ensure USB Debugging mode is enabled on the phone by navigating to Settings > Developer Options (if the phone is running Android 4.0 or later) or go to Settings > Applications > Development (if the device is running Android 2.3 or earlier). If your device is running Android 4.2 or later, do the following steps:
  • Go to Settings > About Phone
  • Scroll down to the bottom and select Build Number
  • Tap Build Number about seven times until the hidden Developer Options is unlocked or revealed under Settings. Then enable USB Debugging mode by selecting the checkbox.
• Ensure that the device has at least 85 percent battery charge.
• Make sure that the phone is factory unlocked and rooted with ClockworkMod (CWM) recovery installed on it.
• Double check to confirm that Wipe Cache partition and Dalvik Cache Wipe is done before continuing from the Recovery Mode
• Samsung KIES will not recognise your phone after installing the firmware, as it is a custom release.
• The instructions provided in this guide are meant for reference purpose only. IBTimes UK reminds its readers that it will not be held liable if the device is damaged or bricked during or after the ROM installation. Users are advised to proceed at their own risk.
