(Updated: Video Added) We’ve covered a great news previously telling that Chainfire has invented easiest way to root Samsung’s high-end phone, the Galaxy SIII (SGS3). More great news is also coming recently, he has pushed out his popular root tool “CF-Root” and made it capable to put Galaxy S3 rooted. However, meanwhile CF-root only works for GT-I9300 model of SGS3. So before you read this guide even further, go check your handset model by going to Settings >> About device >> Model number and you should see your SGS3 model there.
p.s: Do not try using this version of CF-root for other model than GT-I9300.
About CF-Root For Galaxy S3
For your information, CF-Root is not like many other Android root tool. This one is basically a simplest entry point to superuser status on your SGS3. The developer “Chainfire” means this tool to replace your original Samsung kernel with a rooted variant but keeping as close to stock as possible. The CF-Root pack contains SuperSu to allow your apps gaining root / superuser access, ClockWorkMod Recovery v5.5 (CWM) to flash ROMs as well as doing Nandroid tasks, and also there is a CWM Manager app to do all CWM tasks from normally booted Android (not going to recovery).
Extract all downloaded file above in your Desktop for easy access. For extracting CF-Root-SGS3-v6.0.zip file, make sure you get a .tar file.
Turn off and reboot your SGS3 into “Download Mode” by pressing and holding down Volume Down + Home + Power buttons. And when you see an exclamation alert, simply press the Volume UP button.
Now plug your SGS3 into your computer using its USB data cable.
Now launch Odin up by double-clicking Odin3 v1.85.exe file.
On Odin, click on the PDA tab then select the recovery file with .tar extension you’ve extracted before.
Please leave everything else on Odin intact and make sure Odin’s Repartition option is not checked.
Take a deep breathe and click on the “Start” button.
Sit tight and wait for Odin to install CF-Root and its content on your SGS3.
Once done, your phone will reboot.
Voila.. your Galaxy S3 is now rooted.
The Video Guide
FYI: Flashing custom firmware (well in this case we flash CF-Root – not a firmware actually) will increase the number of flash counter been made to your device. Obviously flash counter is one of consideration for Samsung’s Service Center regarding its warranties. So you may also need to reset that “flash counter”. To do that, simply download and install TriangleWay.
