Installing Android 4.3 Paranoid Android ROM On Galaxy S3

The Paranoid Android 3.97 ROM is among the quickest and most stable Jelly Bean builds available for the Samsung Galaxy S3, with a number of bug fixes and features like Hybrid mode.

This guide will walk you through the installation process. As always, Droid Report assumes no liability for the firmware installation. Proceed with caution.

Before Getting Started

This guide is intended only for Galaxy S3 handsets bearing the I9300 model number. Flashing any other device through this method may result in a bricked phone.

You will need to be rooted and running ClockworkMod.

As always, you want to backup your device and charge it to at least 80 percent. Finally, enable USB Debugging mode by navigating to Settings -> Developer Options.

Installing Paranoid Android 3.97 ROM (Jelly Bean 4.3) On Samsung Galaxy S3

1) You’ll need to download the ROM, which can be found here, as well as the Google Apps package and NFCfix.

2) Using your USB cable, connect your Galaxy S3 to a computer and copy the Paranoid Android 3.97 ROM and Google Apps package to the root folder of your handset’s SD card.

3) Boot into Recovery mode by holding down Volume Up, Home and Power buttons together.

4) Using CWM recovery, perform “wipe data/factory reset,” “wipe cache,” “wipe dalvik cache,” and finally, format the system through the “mounts and storage” submenu.

5) Navigate to “Install Zip from SD card” within CWM recovery and navigate to the ROM you copied earlier, which will be in a .zip archive. Once you select the ROM, your Galaxy S3 will begin to install Paranoid Android 3.97 and the process should take five minutes or so to finish. Do nothing until the installation is complete.

6) Repeat Step 5 to install Google Apps, as well as NFCfix.

7) Once the ROM is loaded, navigate to “Reboot System Now” and allow the phone to restart. Once it boots back up, you are officially running Paranoid Android’s 4.3 Jelly Bean custom ROM. Kudos.
