How to install Android 4.2.1 LiquidSmooth ROM on Sprint Galaxy S3 L710

The Samsung Galaxy S3 is among the Android devices that are often the center of developers’ lust to produce cool ROMs. We’ve already published guides on how to flash CyanogenMod 10.1 and Slim Bean ROMs into Samsung’s flagship. This time around, we will guide you through the successful installation of LiquidSmooth ROM based on Android 4.2.1. However, this tutorial is intended for Galaxy S3 with model number L710 or the models being carried by U.S. carrier Sprint.



The installation of LiquidSmooth ROM is simple and straightforward. Owners who are willing to take the risk would have to download two packages: the LiquidSmooth ROM and Google Apps for Sprint Galaxy S3. The ClockworkMod Recovery will be used to flash these packages, so owners will have to install it prior to taking the first step of this tutorial.

Disclaimer: The LiquidSmooth ROM, albeit stable, is still under development. Owners may encounter bugs or other issues that may lead to the bricking of their phones. Such risks are always involved whenever custom ROMs and mods are flashed manually into the device. If you want to proceed, then it’s on you. You can neither blame The Droid Guy nor the developers behind the ROMs and mods used in this tutorial.


  1. Your device must be rooted and bootloader unlocked.
  2. You should backup all important data inside your phone including SMS messages, contacts, videos, music, files, etc…
  3. ClockworkMod Recovery must be installed.
  4. USB Debugging in your phone should be enabled.
  5. Drivers must be installed in your computer so your device can be detected without problems.
  6. You must create a Nandroid backup of your current ROM.
  7. Make sure your device has, at least, 80% battery left.
  8. Download LiquidSmooth ROM and save it in your computer.
  9. Download Google Apps.

Step-by-step Tutorial

Step 1: While your phone is still on, connect it to your computer with the USB data cable and copy the packages you just downloaded into your phone’s internal memory. Make sure you save them in the root directory to make them detectable for ClockworkMod Recovery. There’s no need to extract them.

Step 2: Disconnect your phone from your computer and turn it off to make it ready for the process.

Step 3: You may now boot your device into ClockworkMod Recovery mode: press and hold VOLUME UP + POWER + HOME buttons until Samsung logo comes up. The recovery screen would soon appear.

Step 4: Make a Nandroid backup of your current ROM: Backup and Restore => Backup.

Step 5: Go back to recovery main menu then choose Wipe Data/Factory Reset to perform full data wipe. It may take a minute to complete.

Step 6: Now begin flashing LiquidSmooth ROM into your phone: Install zip from SD card => Choose zip from SD card and browse through your device’s internal memory and locate file. Press POWER button to confirm your action and commence the process. It would take a few minutes to complete so be patient and wait until it’s done.

Step 7: Repeat the process in step 6 but this time choose the file to flash Google Apps.

Step 8: Go back to main menu and choose Reboot System Now. Wait until your device is fully booted before you use your device. The first boot after installation would usually take longer than usual.

Your Sprint Galaxy S3 is now running Android 4.2.1 Jelly Bean with custom LiquidSmooth ROM. There are a lot of things you can do using this ROM not to mention your device is now more responsive than before.
