How To Install Android 4.1.2 On Samsung Galaxy S GT-I9000 Via C-Rom Mix

C Rom Mix custom ROM on Samsung Galaxy S GT I9000 How To Install Android 4.1.2 On Samsung Galaxy S GT I9000 Via C Rom Mix

When I first experienced the Android sensation was on a Samsung Galaxy S GT-I9000 device that came with Android 2.1, also known as “Eclair”. To be honest I wasn’t quite impressed at the beginning, giving the fact that my previous smartphone was an iPhone 3GS, but once I’ve managed to install the Android 2.3 Gingerbread update the things got an amazing turn. In my opinion Android 2.3 Gingerbread was and still is one of the most stable Android versions developed by Google.

At that moment having the 2.3 version installed on your Android device was everybody’s dream, but now that OS doesn’t look so good when it’s compared with the latest Android version – Jelly Bean 4.1.2. As you might know, the Korean company restricted the OTA update for Galaxy S to Gingerbread, which makes me really sad, because it basically restrained its customizing potential.

So, to show my consideration to my first Android phone, I decided to show you how to flash the controversial Android 4.1.2 Jelly Bean on your one and only Samsung Galaxy S GT-I9000. This thing is possible thanks to a XDA Developers member, who managed to combine the latest custom ROMs available on the Android market – AOKP Jelly Bean and CyanogenMod 10 – into a C-RoM Mix custom ROM.

C-RoM Mix feedback was that improves you devices battery life, performance speed and stability while you will be able to experience the latest Google Apps version and the famous Semaphore JB 2.4.4. kernel.

Now, if you are ready to get rid of that old and boring Gingerbread official update, you should follow the next instructions on how to upgrade your Samsung Galaxy S GT-I9000 to Android 4.1.2 via C-RoM Mix.

Requirements and warnings

  • The information in this tutorial is compatible only with Samsung Galaxy S, model number GT-I9000. In case you have a different device, than I strongly recommend you not to use this guide.
  • To be sure that nothing wrong happens to your personal data, it’s best to do a proper backup first. Follow this Android backup guide if you don’t know how to do it.
  • Flashing a custom ROM requires a rooted Android device that has a custom recovery tool installed (ClockworkMod Recovery).
    - Follow this tutorial on how to root and install CWM Recovery on Samsung Galaxy S.
  • This kind of procedures demands a lot of power, so make sure the battery life is higher than 70%.


  • Download the “C-RoM Mix” custom ROM from this source (the file has around 287 MB, so it can take a while).
  • Once the downloading process is complete, just save the “.ZIP” file directly on your Galaxy’s SD card (internal).
  • Turn off your device.
  • Boot your device into CWMod Recovery (press and hold down the “Volume Up” > “Home” > “Power” buttons). Once you are in recovery you can use the volume keys for navigation and the “Home” or “Power” buttons for confirmation / selection.
    - Note: An alternative to this step is not to turn your device off, go to “CWM” application on your phone (it looks like a settings wheel) and select the “Reboot into ClockworkMod recovery” option form the “Reboot” tab.
  • When the device boots into Recovery > go to “Backup and Restore”, select “Backup” and wait until a NANDroid backup of your ROM is created (this is like a safety measure).
  • When the backup is complete, go back to the main menu.
  • Select “Wipe data / factory reset” and press the “Home / Power” button for confirmation.
  • Select “Wipe cache partition”.
  • Go back to main menu once again and select the “Install ZIP from SD card”.
  • Now select “Choose ZIP from SD card” and guide your device to the “.zip” file saved on the internal card.
  • Confirm the installation process by pressing “Yes”.
  • Wait a few moments and then select the “Reboot system now” option to end the installation process.

Congratulations!!! Your Samsung Galaxy S GT-I9000 is now successfully updated to Android 4.1.2 Jelly Bean, thanks to the C-RoM Mix v5.0 custom ROM.
