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

NOTE: Before flashing, make sure you have enabled "OEM Unlock" from "Developer Settings" !

- 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 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 practice!)

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, boot with Vol Up+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.

what about tripping knox ? can you please telll us if cf-autoroot does trip knox ?
[Galaxy A3, A5, A7, A8, A9 Android Development] shubham540:
First of all, plz don't quote the whole post :/

Secondly, tripping knox means your warranty will void if you root your device, yup, CF-Auto-Root tool will trip the knox counter from 0 to 1 for forever, Official counter is 0. And once you rooted your device, the counter will always stay on 1.

I got my A800F rooted with SpaceX. Does this way also give a result with Red Notification on Boot "Kernel Is Not Seandroid" as well? and do I need to try this method too after I rooted my A8 earlier with SpaceX?
[Galaxy A3, A5, A7, A8, A9 Android Development] shubham540:
Well, CF-Auto-Root just released today for A800F, even i did'nt tried it yet on my device, so i don't know about this, i was used this root on my Galaxy S4 (GT-I9500) and i did'nt get any Red Notification on Boot "kernel is not seandroid" like warnings. Now you already replaced your kernel, so you don't need to try this method, but if you want to solve your "Red Notification" on boot, firstly you need to flash Stock Firmware, after that you can try this method. I hope you will not get any notification after that. :)
[Galaxy A3, A5, A7, A8, A9 Android Development] Rei Zazie:
Thanks, but what method did you try to root your A8? if you use SpaceX, did you also get the red notification?
[Galaxy A3, A5, A7, A8, A9 Android Development] shubham540:

[Galaxy A3, A5, A7, A8, A9 Android Development] Rei Zazie:
haha,, I see... Well this is my first time with Samsung device, so yeah I got confused and honestly worried when I got the red notification (since it is right on the first bootloader screen where the "Samsung Galaxy A8 powered by Android" screen appears, it has additional red notification on top left). And I'm still wondering if it could be removed somehow because I got that red notification, not red triangle or whatsoever it is... :rolleyes:

I would try this method instead if only I got this news faster.

Hi, I want to root my A7(2016) to enable the screen mirroring. Saw on some other forums that if screen mirroring is not present by default, then by editing the build.prop we can have it back. So anybody with rooted phone, please confirm whether this hack works with A5, A7 -2016 models. The hack is :

Navigate with a root explorer to your build.prop file located at /system/build.prop . Add the followine line in the end of build.prop

persist.debug.wfd.enable=1

Save your build.prop file and reboot.

After this try installing "Miracast Widget & Shortcut" app from playstore and try to mirror. Please report back. I will be thankfull if someone tries and reports back. We should try to find the solution of screen mirroring issue on these phones.

Hello Mr. Chainfire Sir, is there any chance for an autoroot for Galaxy A5 (2015) SM-A500FU on android 6.0.1 as Most Galaxy A5 (2015) models are already granted autoroot on android 6.0.1 . The SM-A500FU is still marked as Android 5.0.2 wich is bad since i recently made the update and now I can't enable application write acces to my external sd card since I don't have root priviledges i can't apply this hack.

So Is there any chance Auto root comes to SM-A500FU for android 6.0.1?

I prefer auto root over twrp as autoroot is simple and easily reversible, however instructions for twrp seem more complicated and seem to varry from site to site so i'm not convinced to try something I'm not confident of doing, Hence still waiting for autoroot for my phone version.

Recovery is not seandroid enforcing

to everyone stuck up at RECOVERY IS NOT SEANDROID ENFORCING,

seems like problem with included modified recovery - so go with twrp instead :)

mine device got stuck with that message and cannot pass the recovery to boot up. so i went here, got myselft twrp, went back to odin and flash it.

here is mentioned to uncheck Auto Reboot option because "...else the TWRP recovery will get wiped by the stock recovery". that option was greyed-out in Odin for me so i loaded familiar "CF-Auto-Root..." tar file, unchecked the option, and loaded twrp tar file again. flashing went okay, booted into twrp manually, copied SuperSU zip file onto the phone and flashed that in twrp to root the device.

seems messed up but its just a workaround for included recovery that cannot make its way on some devices for some reason.

so if you got stuck with RECOVERY IS NOT SEANDROID ENFORCING, the steps are, once again:

- get twrp for your device

- flash it with odin. uncheck auto reboot option.

- manually reboot to recovery

- flash supersu zip to root

- hit thanks :p

Help needed with correct CF-AutoRoot for A700FD

I'm a new user to xda forum. So i wasnt able to start a new thread. So, here I am. Excuse me.

I needed to root my galaxy A7 device. So I headed over to the CF-AutoRoot Page and found my device there. Downloade the file and Flashed the device using Odin (latest version). But it failed and returned an error saying "Recovery is not Seandroid Enforcing".

What went wrong?

Then I found the build number was different. To my understanding, the build number is the main reason I'm not able to root my device. Check the screenshots below.

I found everywhere possible but I'm not able to find the same build number CF-AutoRoot file. Is it possible to get the file for the given build number. Or any other methods are always welcomed.

Build number of the latest file on the website : MMB29M.A700FDXXU1CPH5

Build number of my device : MMB29M.A700FDXXU1CPI5

Thanks. :)

I'd suggest that you root your phone manually as the CF-Auto Root bricks your phone. That's the issue I'd faced in the past

To root your phone, just boot your phone into download mode (odin mode) and flash the TWRP (SM-A700FD)

TWRP- https://xdaforums.com/samsung-a-series/orig-development/recovery-teamwin-recovery-project-t3253126

The installation instructions are provided in the thread

Make sure that you've downloaded the SuperSU file Obviously the latest one and place it in your SD card

MAKE SURE THAT YOU'VE YOUR STOCK ROM AS A BACKUP

Link for SuperSu - http://www.supersu.com/download

After you've flashed TWRP, boot into recovery and flash the SuperSU file (.zip file) and reboot.

Make sure to check if you've successfully rooted your device by using RootCheck for the Google Play.

First, install the Xposed apk and then boot into recovery and flash the .zip file and reboot.
