1) Has anyone managed to root his note 4 with cf-autoroot with the lastest stock ROM from feb 2019 ? ( N910FXXU1DRI2 N910FOXX1DSB1 )

2) Same with TWRP, I flashed the lastest TWRP for my note 4 but it's not working since I installed the official lastest stock ROM.

I'm wondering if it's my fault or not.

SU Binary occupied

I just installed it on ma SM-N910C.
Works fine the first time but now SuperSu app show the message "SU Binary occupied".
Is there a solution to this message ?

Downgrading SuperSU Free to version 2.79 SR3 solved the problem.

There is a way to root the AT&t version..... I have not personally done this but I have an old friend who did... It had something to do with using bootstrap..., I don't remember if he had twrp installed or not.. but there is light at the end of the tunnel

I'm trying to root SM9100.
My odin doesn't have the button in the original guide, only "AP" button.
Everything 'seems' to be working fine in odin, but my phone is sitting at like 1% download and it's been 10 minutes already.
Any ideas?

Plase I need few inforations:
1) I have an old NOTE 4 sm-n910F with android lollipop 5.1.1 and I want to root it.II have the reAd that I will not lose all my data (an important thing for me) and that now the CF root is fool compatible with andrid lollipop 5.1.1 so I just need to flash it with odin without need to flash olso (after) the TWRP is that correct?

2) If one day I will decide to unroot my device there is a way to uninstal the cfroot always without looseing data or the ony way will be to installl with odin back again the stock firmware lollipop 5.1.1? I ask that why I use some app for my banck and I'm afraid that the root can give some security problems loging me in
Thank's in advance who will be so kinde to answer helping me :)

    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, S2, S3, S4, Galaxy Note, Note2, Note3, dozens of Tab models, etc!) and has clocked over 32.5 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).

    Using this root increases your flash counter and trips the KNOX warranty flag!

    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.

    Other models

    CF-Auto-Root is not yet available for all models - one stock firmwares for these models become available, let me know, and I'll make the corresponding CF-Auto-Roots. Make sure to check the main CF-Auto-Root site as well, as models may be listed there that are not listed here yet!
    Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!

    - Download and unzip the CF-Auto-Root-....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.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!
    Sprint and US Cellular versions added
    Just added N910F, N910K, N910L, N910T and N9108V models to the list.
