From here it seems that how fast are the Android developers as its just a week passed since Google Android 4.3 a short time back and the update began rolling-out almost immediately. Paranoid Android Build for Android 4.3 is now available for download. Currently It’s available for the Nexus 4 smartphone only.
Users can flash the ROM titled “Nexus 4 Mako 4.3 JSS15J Preview” via recovery by interested users. Its a preview ROM which means you need to flash Android 4.3 Gapps also after flashing the ROM. If you cannot wait for a stable version of PA to be out, head over to this Google+ thread for the download link and flashing instructions.
