This custom ROM is based on CyanogenMod 11 source and Android 4.4 AOSP. More info about this custom ROM can be found here. The custom KitKat build has been created by ‘pawitp’, an XDA member and developer. Note that you might find some bugs and errors while using this ROM, but these are normal at this early stages.

However, make sure to thoroughly test this Unofficial CM 11 build and check all the latest KitKat goodies.

For this new custom ROM to successfully install you will have to take a look at the preparation guide below:

  • Use this post only with the Samsung Galaxy S model number I9000.
    – don’t attempt to update any other devices with the files you find in this post, as you will end up bricking it.
  • The Galaxy S has to be factory unlocked, rooted and running the CWM Recovery.
    – without these you cannot flash any new custom ROMs on your device.
  • For the new ROM to install correctly, you will first need to apply a ‘factory reset’.
    – that process will remove all data from system partition, while the internal storage won’t be affected.
    – this step can be found in the tutorial, don’t skip it.
  • Create a NANDROID Backup of your currently installed ROM before installing CM 11 test build.
    – this step can also be found in the tutorial.
  • Backup data from apps that are installed on your device with Helium tool here.
  • Backup SMS text messages and APN Internet Settings using these tools for Android: SMS backup & restore | APN Settings Backup & Restore. Root access is needed for these small apps.
  • Sync Contacts info and People details with your Gmail account.
    – if you don’t know how to do it, then you should follow the info listed here.
  • Enable USB Debugging from Developer Options.
  • Check the phone’s battery power levels and make sure that it is over 50%. This will ensure that your device won’t switch off in the middle of the updating process.
