PLEASE TEST IF YOU HAVE THE multitouch issue BEFORE ROOTING, AS ROOTING WILL VOID YOUR WARRANTY Read this post: I have not had time to look into this myself unfortunately, as I'm travelling. Better safe than sorry.

Check your device model ! Settings -> About device -> Model number. See the third post for exact supported model numbers. If your device is a totally different model, it will not work (may even brick) !

CF-Root is the root for "rooting beginners" and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares, and be the quickest and easiest way for your first root.

CF-Root has been available for many devices (Galaxy S1, Galaxy Tab 7", Galaxy S2, Galaxy Note, Galaxy Nexus, Galaxy S3, and many more) and has clocked over 16 million downloads. This is not even counting custom ROMs that already include it. Don't be a leech, buy me a beer (and use the "Thanks" button!). Imagine if every CF-Root user has donated me $1...

What's installed
- SuperSU binary and APK
- Stock recovery

Installation and usage
Flash the CF-Auto-Root package as PDA in ODIN (details on how to do that are in next post), and your device should reboot into a modified recovery (signified by a large red Android logo) and it will install SuperSU for you and restore the stock recovery, and reboot back into Android.

If you don't get to the red Android logo, boot into recovery manually ("adb reboot recovery", or boot while holding Power+VolUp+Home).

Did you see the red Android logo during rooting, but SuperSU does not appear? This may sometimes occur due to left-over files and settings, however, you can usually install SuperSU from Google Play at this stage and it'll just work.

Flash counters and KNOX warranty
Using this root method sets current binary and system status to custom. Additionally, it will also trigger the KNOX warranty void status.

This device store the traditional flash counter. Nor is is possible with Triangle Away to reset the current binary status. You will need to flash a stock kernel and stock recovery to reset the binary status.

The KNOX warranty status change is permanent, and a service center may deny warranty based on this flag - even if the other flags are reset correctly. The KNOX flag being tripped may also prevent certain Samsung KNOX features from working (enterprise security features). If this is something you care about, use a root method not based on custom kernels or recoveries, like a modified system partition. These are possible, but I don't personally make them, so look around!

Why isn't this just called CF-Root
The traditional CF-Root's included a custom recovery (CWM, TWRP, etc) and were meant for devices that had a single kernel/recovery combination. CF-Auto-Root doesn't include a custom recovery and is meant for devices that have kernel and recovery separate (so you can manually install any custom recovery you wish). The Auto part comes from the fact that a large part of the process is automated (though it constantly needs adjusting)

Not included - Triangle Away
Unfortunately, Triangle Away cannot currently be used on this device to reset the binary status or KNOX warranty void. It can still usually reset the system status, but that is of limited use.

Not included - adbd Insecure TODO: STILL UNDER DEVELOPMENT. Hopefully I'll get this to work soon.
As this CF-Root does not include a custom kernel, adb shell does not have root access by default (you can still get it by typing su inside the shell), nor is adb remount supported, nor will adb push and adb pull work on system files. adbd Insecure can be used to remedy this situation. (No idea what this is about ? Don't worry about it !)

Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!

- Download and unzip the 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.md5 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-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+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!)

NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.

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.

CF-Auto-Root is not yet available for all carrier-specific Note3's. Link me to stock firmwares for these devices as they appear, and I might be able to make a device-specific CF-Auto-Root.

What is happening Chainfire? The dev are working on some solution for the knox efuse? I am thinking about a software which can restore that flag or a software which skips triggering while rooting.. for this you guys need to sign the modified stuff which is hard. How you see the things at the moment? This is the only thing what is holding me back to buy the note 3 at the moment...

Waiting your great work for the Exynos model as well...

You asked for a stock firmware link here is one for N900 model:

Actually I need for N9000Q model but on Sammobile there were just N900 model, i hope those are same since both of them are for the same device (Exynos).
