Nestle would never have even imagined that some day billions of Android users would start chanting the name of one of its confectionery products. I never have seen such a brilliant way of advertising any product. Everybody with an Android phone or tablet is looking to get KitKat. While Nexus users have already been enjoying the new flavor of Android, or about to receive it anytime soon, there are billions others who are still looking toward their device  OEMs and carriers to have at least the lower versions of the platform like Android 4.2 and 4.3.

Owning a Google Nexus device is a kind of guarantee that you would be one of the first to receive the latest version of Android, but if you got a phone/tablet from manufacturers like Samsung, LG, HTC, Sony, etc., you might have no choice but to wait perpetually. Even if you get a new (?) update, it’s got to be  an old thing by the time it reaches you. Samsung’s treatment with its popular phones like the Galaxy S3 and Note 2 is a very relevant example of how manufacturers shirk from sending software updates to their users.

Yesterday we published an article on installing Android 4.4 KitKat based custom ROMs on the Galaxy Note 2 and many of its variants. Extending our KitKat treat, we have now come with a collection of Android 4.4 custom ROMs for the Samsung Galaxy S3. If you own any of the following variants of the device, you can update your phone with the newest sensation of Android:

  • Samsung Galaxy S3 GT-I9300
  • Samsung Galaxy S3 LTE GT-I9305
  • AT&T Galaxy S3 SGH-I337 (the ROMs for this model can also be installed on the Canadian variants e.g, Rogers, Bell, Telus, etc.)
  • Sprint Galaxy S3 SPH-L710
  • T-Mobile Galaxy S3 SGH-T999
  • Verizon Galaxy S3 SCH-I535


The procedure described below is not meant for perfect noobs as it is considered risky. Follow all instructions carefully if you do not wish to caught into a compromising situation. We would always be at our end to help you in case of a mishap but we take no responsibility. Proceed only if you agree to these terms.


  • A rooted Samsung Galaxy S3. If you have not rooted your phone yet, please take some time and root it using our easy rooting tutorial.
  • The KitKat ROMs we are going to talk about are custom ROMs and therefore they require the presence of a custom recovery like ClockworkMod or TWRP on your device. Not only this, you must have the latest version of the recovery you use. You can download ROM Manager (CWM) or Goo Manager (TWRP) to install the latest version.


Since Goo Manager is working properly these days, we recommend that you install CWM version on your device. If you know how to install recovery image file using ADB command, download the latest CWM recovery .img file from here and install it.

About the ROMs:

Please note that most of the ROMs that we have mentioned below are based on CM 11 and therefore have all the bugs of their parent. Being in early stage of development, it is obvious that you might encounter a few bugs in performance. Please install the appropriate ROM on your phone, test them and if you find them stable enough for you,use them. We hope that with new updates, all these ROMs will become more mature and stable.

How to Install:

  1. Important: Do not forget to backup your phone’s EFS/IMEI before. Read this article for detailed tutorial.
  2. Charge your phone.
  3. Copy the downloaded Android 4.4 ROM file and the latest Gapps package from above and copy them to your phone.
  4. Also copy the SuperSU zip file to the device.
  5. Boot your Galaxy in recovery mode. Here is how to do it: hold down the Volume Up+Home+Power buttons together for 4-6 seconds till the screen turns up and you see the recovery screen. Alternatively,you can enter recovery mode using  these apps.
  6. If you are using CWM, use the volume keys to scroll up/down and the power button to select files and options. TWRP users can simply touch the corresponding buttons to get a job done.
  7. Important: Before doing anything, do not forget to backup your current ROM using “backup and restore”option (in CWM) or “Backup” option (in TWRP) and check all items to backup.
  8. CWM Users: Go back to main menu in recovery and select “wipe data / factory reset> yes”. Then go to“mounts and storage” and wipe data and system.
  9. TWRP Users: Just tap on “Wipe” button and select Data, System and Cache.
  10. Now go back again and choose “install zip from sdcard> choose zip from sd card” option, select the ROM file in zip and choose “yes” when asked. If you have TWRP, use “Install” button, select the ROM and swipe the slider to confirm installation.
  11. When the ROM is installed, install the Gapps zip package just like you flashed the ROM in Step 11.
  12. Then install the ”” file the same way.
  13. Finally, select the reboot system option.

The first boot will takes longer than usual so wait patiently till the device boots up and you see the welcome screen. Go through the startup setup like data connection, Gmail, Google Wallet, etc.  In case you have any doubts or question, feel free to share your thoughts. Thanks!
