[AT&T Samsung Galaxy Note5] droidvoider:
Please thank Delgoth + lowandslow200sx for this root!!

Warning: This can lead to a ruined phone that can't be repaired proceed with caution!

Warning: This HOWTO erases your contacts, stored music + photos, apps + data, Internal Storage, all of it GONE. Back it up before continuing!!

Notice: When finished you will remain on Android 6.01 Marshmallow, you will not upgrade to Nougat. But you can get rid of AT&T + Samsung apps and extend battery life by a lot! You can do a lot more than that but it is SELinux Enforcing, so you still have some limits

Introduction

This HOWTO will outline how to gain root on AT&T Note 5 Marshmallow 6.01 through Nougat 7.0 before Feb 2018 update! i.e. basebands beginning in N920AUCS4. Such as N920AUCS4CPK1 through N920AUCS4EQL1

If your baseband is N920AUCS3 or lower you can already root with Wondershare GoMobile (start at step 9)

If your baseband is N920AUCS5 then this method won't work for you.

Please be aware

This is 1 of 2 root methods for binary 4 N920A Note 5 AT&T Phones!! There is also a Lolipop Android 5.11 root method that allows selinux permissive persistent root you can use on Post 51 of this thread!

Gain root to disable any app and do other cool stuff

1. You need the drivers for Note 5 but they are likely already installed test it via. Connect the USB charging cable between your computer<>Note 5 you should see your phone pop up in File Explorer

(if you can't connect to your phone find the Samsung Note 5 drivers first)

2. If you don't have adb installed first install it on your machine (you can test it by opening a cmd prompt and typing adb, you should get instructions for use)

https://www.xda-developers.com/install-adb-windows-macos-linux/

3. Install Wondershare GoMobile, it's a 5 day trial so be ready to do this!!

4. Download and Unzip the Customized PJ1 + PK1 Firmware into a directory

https://drive.google.com/open?id=1qHVndp4wZXeKb5TFZSnsUT-s3EBmkHVW

5. Download Odin and Unzip it to a directory then click the file to start it up.

6. Select Odin Options tab and in Odin check Auto Reboot, F.Reset Time and Nand Erase All

(load the 4 files from the Customized PJ1 + PK1 zip into the respective slots)

7. Place phone in download mode, connect it to your PC then in Odin select Start to flash the firmware, you can unplug cable when phone reboots.

8. During initial phone setup disable Wifi, skip Google Play account, exit or skip everything you can.

9. Disable security updates under SETTINGS|PERSONAL|Lock screen and security|Other security settings|Security policy updates|Automatic updates OFF

10. Enable Developer options under SETTINGS|SYSTEM|About device (tap build numbers 7 times) then push arrow back to SYSTEM and open Developer options.

11. Under Developer options OEM unlock and USB Debugging should both be ON

12. Always allow usb debugging on phone screen when you are asked. Also allow MTP file transfer.

13. If Google asks for feedback data always DECLINE, they don't help us!

14. Connect cable and connect to Wondershare GoMobile then "One Click Root"

15. After success open Windows Command Prompt and type adb shell, then su

16. You can disable any apps now but start with these (copy / paste into cmd windows then hit enter)

pm disable com.ws.dm

pm disable com.sec.android.soagent

pm disable com.policydm

pm disable com.samsung.android.securitylogagent

pm disable com.lookout

17. You can enable Wifi and Sign in the Google Play now.

18. If you reboot your phone you need to use One Click Root again to regain root, but you are free to unplug the cable!

(If you crash your phone enter recovery mode, wipe data/factory reset, wipe cache and then start over from step 8.)

Restore PK1 boot.img and recovery.img to close dirtycow vulnerability (removes ability to gain root)

1. Download this to a directory but don't extract it

https://drive.google.com/open?id=1374IZTBeyNBELdrK1ESdqkUuVGutbpDm

2. Load PK1boot_recovery_img_only.tar.md5 file into the AP slot in Odin

3. Place phone in download mode, connect it to your PC then in Odin select Start to flash the firmware, you can unplug cable when phone reboots.

Please let me know if any steps are unclear. I can reverse the rooting method but there's probably 20 people world wide who will use this method, so if you have security concerns make sure to close dirtycow vulnerability when you're done and just use the one click root method.

Updated notes:

If you get a Screen Overlay Detected error turn OFF overlay for both MobileGo apps!

I added a windows batch script to disable a lot of apps (root first with wondershare gomobile)

If you use the phone it looses root and becomes harder to root. (if it become impossible to root again flash the PJ1 boot and recovery only file but backup before you do it)

Don't create things with Assayed Kitchen then flash them to the phone or mix firmwares it almost refuses to enter download mode again :fingers-crossed:

In case of error

During the learning process to do things like this putting your phone into a bootloop or soft bricking is very common for new comers, but don't panic. After you complete the process I outlined it will take a couple minutes to boot it will have the AT&T logo on a white screen. If it hangs here for a really long time or it gets unusually warm this is a bad sign. Let's get the phone turned off so you can think.

Hard Reset: press Power + Volume Down for 7 seconds

Screen goes black: immediately presss Power + Volume Up + Home

Use Volume down to move to option Power Off then push the Power button to select it.

You can start over / try again by pressing Power + Volume Down + Home buttons again
