Samsung Galaxy S2Even though the Samsung Galaxy S2 totally has the hardware to rock it, it will be now safe to assume that this ex-Samsung flagship is never going to see an Android 4.3 OTA update. However, that just doesn’t mean that the Samsung Galaxy S2 owners are going to be stuck on Android 4.1 Jelly Bean forever. Thanks to the folks over at Carbon AOSP ROM, an Android 4.3 ROM which is specifically made by handpicking special features from ROMs like CyanogenMod, AOKP and ParanoidAndroid, there is now a stable Android 4.3 ROM available for Samsung Galaxy S2.

Before beginning with the whole flashing process, you first need to ensure that you satisfy the following points.

  • This method is only applicable to the international version of the Samsung Galaxy S2(GT-I9100) only. Applying this method on any other device might lead the device being bricked or damage that is very hard to repair. If you are unsure about your device’s model number, you can check it easily, by going to Settings menu and then tapping the About Phone option.
  • Make sure to backup all of your data. We can not stress this part enough. Even though there are very light chances that anything will ever go wrong with your Samsung Galaxy S2 during the flashing process, it is always better to be safer than to be sorry.
  • Ensure that your Samsung Galaxy S2 is already rooted and has ClockworkMod (CWM) recovery installed on it.
