Even though Android is an open source mobile operating system, which offers the user a lot of customizable options it is likely that you’re going to have a limit on them setup by the manufacturer of the device, just like with Samsung Galaxy S3 GT-i9300. In order to fully access the features that Android has to offer you will have to use a special tool to unblock the operating system.
In order to do this you will have to install a special tool called CF-Root that will remove from your Galaxy SIII all the limitations that Samsung implemented in the operating system. The process that we are going to describe below is called rooting an Android device.
Before anything else, we should point out the fact that all credits for the CF-Root tool go to a member of the XDA Developers forum named Chainfire. Thanks to his work, you can now give permissions to apps like SuperUser, ClockWorkMod build 5.5 or CWM Manager.
The first step of this process would be to check if your device is indeed a Galaxy S3 GT-i9300. By going to the Settings, About device, Model Number menus you will be able to verify this information. Please note that this guide is very likely not to work if your device is GT-i9301 or something similar, due to the fact that it is intended for the initial version of the Galaxy SIII.
Right from the beginning I would like to point out the fact that our website cannot be held responsible if something goes wrong during the process, making your device unusable. Here are the steps that you should follow to root your Galaxy S3 with CF-Root:
- Go to the XDA Developers forum and Download ODIN 1.85. This application allows you to flash the CF-Root files on your S3.
- Download the latest version of CF-Root for Samsung Galaxy S3 and extract the contents of the archive
- Now you should see another archive called CF-Root-SGS3-v6.0 that you will have to be uploaded to your device.
- Run ODIN but not before making sure that the phone is not connected to the computer
- When the application opens, you should click on the button called PDA to select the CF-Root archive that you’ve extracted
- Now you should power off your Galaxy SIII and then open it in Download Mode. This can be done by holding the Volume Down + Home + Power buttons at the same time. When in Download Mode, connect the smartphone to your computer.
- Go back to the ODIN application and make sure to uncheck the option called Repartition. Once your device is connected and everything is setup properly, you should click on the Start button.
Please do not disconnect or power off the device in order to allow for the application to complete the rooting of Galaxy SIII. The whole process should not take more than a couple of minutes but as soon as it’s done, you now have a rooted S3 with CF-Root.
