(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).
Root Requirements
- Make sure your SGS3 has enough battery level
- Download Odin v1.85 for Galaxy S3 here
- Download flashable CF-Root v6.0 package here or here.

Optional Steps
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.
