Update Samsung Galaxy S3 I9300 to Android 4.3 using LiquidSmooth 2.10 Jelly Bean custom ROM

LiquidSmooth v2.10 is based on Android 4.3 Jelly Bean AOSP and now you can flash it on the Galaxy S3 I9300 smartphone. If you want to successfully flash this custom ROM, then you should read the entire post below.

LiquidSmooth Android 4.3 custom ROM comprises features from AOKP, CyanogenMod, Paranoid Android and other popular ROMs. Its main features are the PIE controls support for both lock and home screens, HALO, custom Quick Settings widgets, Profiles, Expanded Desktop Mode and more. If you want to learn more about LiquidSmooth custom ROM then you can visit the developer’s web page here or this XDA thread here.

Before starting the installation you will need to take a look at the preparation guide below:

  • Use this post only with the Samsung Galaxy S3 model number I9300.
  • Don’t attempt to update any other Android devices with the files you find in this post, as you will end up bricking its firnware,
  • Your device has to be rooted, on an unlocked bootloader and running a custom Recovery image like CWM or TWRP. Both custom Recoveries will work with this post.
  • The tutorial will ask you to factory reset the device. This means that you will lose all data from system partition, while internal and external storage won’t be affected.
  • If you want to backup data for installed applications, then you can use Helium app (here) or Titanium Backup (here).
  • SMS, Call logs and APN Internet Settings can be saved using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore.
  • Sync Contacts info with your default Gmail account.
  • Enable USB Debugging from Developer Options menu.
  • This is a guide for advanced users and for those of you who want to tinker with your device. Don’t blame us in case you brick the phone or lose any data in the process.
  • Read all the info I’ve listed and don’t any steps.
  • Make sure that the phone’s battery has enough power left in it before the device switches off completely. If that happens then you will be forced to repeat the entire tutorial once again.
  • It would be best for you to create a full NANDROID Backup for the ROM that is currently installed on your phone. This sets a restore point and it can be used in case something goes wrong during the installation.
  • If you cannot complete the custom ROM flash, then you should ask for more help in comments.
