A CF-Root for the Samsung Galaxy S III has been released. Formerly, we wrote about the Samsung Galaxy S III being rooted by an XDA Elite Recognized Developer Chainfire. Remarkably, the dev did so remotely, without getting his hands on the device at all. We posted a tutorial on how you could root your flashy new Samsung Galaxy S III too once you get your hands on it. The device isn’t even available in the States yet but that hasn’t hindered the talented Chainfire in anyway. Now, he has even released a CF-Root for the same device.
For those as yet unaware, a CF-Root is basically a root for beginners, as Chainfire himself says so. It’s meant for people who don’t want to stray too far from stock and is meant to be used alongside stock Samsung firmwares. Basically if you are looking to perform a root for the first time, all you want is superuser access to be able to run a few programs or simply want to get rid of the bloat – a CF-Root is for you.
You will simply use ODIN to flash the CF-Root package. What’ll be installed is Root: SuperSU, Recovery: ClockWorkMod and Util: CWM Manager.
If you are one of the few lucky ones who’ve already gotten a Samsung Galaxy S III or if you’re looking to get one, follow the instructions below to CF-Root Galaxy S3. Excerpt taken from the original thread at XDA Developers Forum:

How to install – (desktop) ODIN
Short: unpack the ZIP download, you will end up with a TAR, flash this in ODIN as PDA, and optionally install and run Triangle Away afterwards to reset the flash counter.
Long:
- Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Unzip the attached Odin3-vX.X.zip file
- Download and unzip the CF-Root-SGS3-vX.X.zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you’ve extracted twice. You need to end up with a .tar file – don’t extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Root-SGS3-vX.X.tar
- Put your phone in download mode (turn off phone, then hold volume-down + home + power to boot – if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It’s very simple, and us Samsung folk use Odin (or Mobile ODIN) for everything! It’s so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!
You may now optionally want to install and run Triangle Away to reset the flash counter.
How to install – Mobile ODIN
(You already need to be rooted for this)
- Download and unzip the CF-Root-SGS3-vX.X.zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you’ve extracted twice. You need to end up with a .tar file – don’t extract that one
- Put CF-Root-SGS3-vX.X.tar on your internal SD card
- In Mobile ODIN, use the Open file… option and select the CF-Root-SGS3-vX.X.tar file
- If you are running the Pro version, make sure EverRoot is not enabled
- Flash!
Note that if you are flashing this together with a stock Samsung firmware, you must open the CF-Root tar file last, and this will prevent the firmware’s CSC to install (which doesn’t bother me, but some people care about this). Alternatively, flash the entire firmware first (with EverRoot enabled), then flash only the CF-Root tar after it has booted up.
How to upgrade – custom ROM
If you are flashing a custom ROM, chances are it will include root and/or recovery, and there’s no manual action to take.
How to upgrade – Samsung ROM
If you are flashing a stock Samsung ROM, you will probably lose SuperSU (root), CWM (recovery) and the CWM Manager app. Just follow the entire installation procedure again – I recommend the Mobile ODIN option here.
How to uninstall
This is by no means an extensive guide for unrooting, but if you want to sell or warranty your device, I advise the following procedure:
- Use Triangle Away to reset the flash counters, and pull the battery immediately after rebooting starts
- Boot into recovery and perform a wipe, and pull the battery immediately after rebooting starts
- Go to SamMobile and get the stock firmware for your region
- Flash that stock firmware on your device
- Let Android boot, go through device setup (without doing any logins) until Android is fully usable again
- Reboot
- Wait at least 10 minutes
- Check Settings->About device->Status and make sure Device status is not “Modified”
- Perform another factory reset
- Boot into download mode and make sure the flash counter and system status are all set to official
Thank Chainfire for the CF-Root and Samsung for making it easy for developers and stay tuned to Techsliver!
