Questions

Hello,

First and foremost, thanks for your hard work on this!!

So I just got the SM-N9600 with the stock firmware for Android 8.1.0 (Build# N9600ZHU1ARH2) yesterday and I've been trying to root it with no luck. I was able to OEM Unlock and flash TWRP Beta 2. However when I try to flash "N9_S9_for_OEM_issue_devices_V3.zip" in TWRP it gets stuck before reaching the AROMA installer to flash Magisk and I have to hold Vol. Down and power to cancel then reboot to TWRP.

According to the "High On Android" tutorial the only difference in rooting the N9600 vs the N960F/DS is the file used to flash TWRP (I am using the appropriate file for my device to flash TWRP). Should I be using a different zip file other than"N9_S9_for_OEM_issue_devices_V3.zip" to flash in TWRP to finish rooting? I found download links for Majisk here: https://github.com/topjohnwu/Magisk/releases but I'm not sure if I should use v16.0.1 or v17.1 (stable).

Also, does the TWRP Beta 2 work with build number N9600ZHU1ARJ6 (10-12-2018 Update for 8.1.0)? I ran the software update and was unable to flash TWRP Beta 2, Odin kept failing, so I downgraded back to N9600ZHU1ARH2 and was able to flash TWRP Beta 2 again.

I was going to try flashing your boot.img file in the downloads of this post but after reading through the comments it doesn't look like that is needed with beta2 and to be honest, I wasn't sure how to correctly flash your boot.img file.

Any help would be greatly appreciated! Thanks again!
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] klabit87:
Ooh this is new to me. I will update for 8.1 as soon as I can.

Aroma has been an issue I haven't been able to track down so for now aroma is not supported.

For root, follow the instructions in the op and you will be fine.
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] live4thamuzik:
Will do! Just to make sure I do this right -

first - I am flashing TWRP beta 2 with Odin in the AP tab only using the F. Reset option.

second - Manually reboot to twrp, selecting read only until I disable dm-verity

While still in TWRP flash your custom kernel (boot.img) or reboot to download mode and flash boot.img from the AP tab with options f. reset and auto reboot??? <---this is where I am unclear as the instructions just say to flash the kernel

third - reboot to twrp and Magisk v17.1 (stable) or Magisk v17.3 (beta )

last - reboot to twrp and flash encryption disabler.zip

thanks!!
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] klabit87:
I do not mention flashing the boot.img with Odin.

Flash the boot.img with twrp. At the bottom there is an option to select zip or img. Select img and you will see the boot.img that you need to flash.
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] amy91:
Hello,

Thank you so much for your hard work on this development.

I just got a N9600 SD version that runs butter smooth but I want something more.

What am I looking for --> Access to root directory of the filesystem. I do not want to root because my requirement is minor and I do not intend to use Magisk or other custom modules in future. All I want is access to files in the root directory of my phone. Can I achieve this any other way beyond root?

Rooting takes away a significant part of the system (Samsung Pay, Pass, Health?) by tripping Knox that I do not wish to give up.

Any help would be greatly appreciated, many thanks!
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] live4thamuzik:
Status Update:

Flashing your kernel, magisk v17.3 (beta), and encryption disabler did the trick! Thanks for your help!!

Side note:

Not sure if anyone else had/has this issue but, I did notice that since rooting I cannot pair my Galaxy Watch with the phone after rooting. The phone and galaxy watch both show the same passkey and pair but the Galaxy Wearable app will not finish the setup, just keeps asking me to pair the watch in and endless loop even though settings shows the watch is paired.

Magisk v17.3 passes the SafetyNet Check for ctsProfile and basicIntegrity

I also used Magisk Hide on the Galaxy Watch Plugin, Galaxy Wearable App, and Samsung Accessory Service.

Problems persist on Magisk v17.1 as well

Hi, when you flashed the kernel, you mean you flashed boot.img thru TWRP? which one do you pick out of the choices that show up? Could you give me some detailed instruction? My aroma freezes also...
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] live4thamuzik:
rooting sm-n9600

Hi,

As klabit87 said to me a few comments above "aroma has been an issue he hasn't been able to track down so for now aroma is unsupported." I'm guessing you also tried the method used in the tutorial by High On Android using the N9_S9_Root_for_OEM_issue_devices_V3.zip file flashed with TWRP like I did and it froze before displaying the Dr. Ketan spalsh screen. Abandon that method.

Before you do anything backup your device with google cloud, samsung cloud or use smart switch to backup to do SD or a PC.

Files you will need:

*SAMSUNG_USB_Driver_for_Mobile_Phones.exe

*Odin3_v3.13.1

*TWRP_3.2.3-0_N9600_beta2.tar.md5

*klabit87's kernel "boot.img"

*Magisk-v17.1.zip & Magisk-uninstaller-2018901.zip (in case you want to unroot or use SU *later instead of Magisk)

*Encryption disabler.zip

* Stock Firmware from sammobile.com. On your phone, go in Settings>About Phone>Software Information and make a note of Build Number, Service Provider SW ver., and Android security patch level. You will need this information to get the correct stock firmware. (always good to have this handy incase something goes wrong! Mind you once Knox is tripped Samsung Pay, S Health, and Secure Folder are no longer usable, Magisk Hide doesn't fix them.)

DO NOT UPDATE YOUR PHONE TO N9600ZHU1ARJ6 released 10-21-18 - flashing TWRP_3.2.3-0_N9600_beta2.tar.md5 will fail! (you can downgrade back to N9600ZHU1ARH2 09-03-18 if you did)

Rooting Step-by-step:

1.) Run Odin as admin

2.) Add TWRP_3.2.3-0_N9600_beta2.tar.md5 to AP tab

3.) Options - F. Reset Time (uncheck Auto Reboot)

4.) Click Start

5.) Hold Volume Down and Power then once the screen goes black hold Volume Up, Bixby Power to reboot to TWRP

6.) Select Read Only

7.) Select Install

8.) Change the option from zip to img

9.) Flash boot.img

10.) Reboot to TWRP

11.) Select Read Only

12.) Select Install

13.) change option to zip

14.) flash Magisk

15.) Reboot to TWRP

16.) Select Read Only

17.) Select Install

18.) Change option to zip

19.) Flash Encryption disabler.zip

20.) Format /data - (Select WIPE>Format Data>then type "yes" to verify)

21.) Reboot to System :good:

Cheers!

NOTE: if you needed to downgrade (like me) "Auto Reboot" gets re-checked in between downgrading and selecting TWRP in AP. I didn't realize this and now I'm stuck in RMM Prenormal for a third week.

About to throw this phone in the trash.

Downgrading from RJ6 to RH2

That sucks!!! I was able to downgrade with no issues. OEM Unlock stayed on the entire time. How did you go about the down grade? Did you do a clean CSC or use the Home CSC to keep userdata??

This is what I did using Home CSC because I can only restore and setup my phone and apps so many times without getting annoyed -

Download Odin v3.13.1

Extract the firmware file you just downloaded. You should get 5 files:

AP (System &Recovery)

BL (Bootloader)

CP (Modem / Radio)

CSC_*** (Country / Region / Operator)

HOME_CSC_*** (Country / Region / Operator)

Add each file to it's respective field in Odin v3.13.1. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.

Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY

Other options in case first option did not work or isn't possible.

Option 2 VOLUME DOWN + VOLUME UP than USB cable

Option 3 POWER + VOLUME DOWN + VOLUME UP

Option 4 POWER + VOLUME DOWN + HOME BUTTON

Option 5 (Note9) USB cable + VOLUME DOWN + BIXBY

Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!)

Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.

Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC.

Hello wonderful developers. (Do not know if i should post this in this thread - Admin please let me know if its the wrong thread).

Thanks for all you guys are doing.

I recently bought a Note 9 online (mentioned unlocked) and bought it. I found it had a locked to SPRINT network. In the process of removing the lock, checked to see if OEM lock can be unlocked (did not find it in Developers option). So tried to flash (Using a USB and my laptop) ODIN v - 3.13. In the process something happened, and now could not do the following things:

1. could not shut down, could restart (pressing the power + vol down only) but then when i unlock the phone at the restart, i get UI could not be found and ends up again in the unlock screen.

2. could not login as well.

What are my options here. Is there a way to flash using SD card (needs help on how to as do it if doable..)?

Thanks for all your help.
[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] Mentalmuso:
What was it you tried to flash in Odin exactly? Being oem unlock wasn't in Dev settings, you shouldn't have tried to flash anything custom.

In fact, I hope Knox hasn't tripped as I wouldve sent it back to the seller and bought an unlocked

So uhh, after my my third week in RMM jail, I am now unable to boot. My phone boots to a message that says "Security Error: This phone has been flashed with unauthorized software & is locked."

Here's what I did:

1: OEM Unlock switch toggled

2: Waited for RMM Prenormal

3: Flashed TWRP in ODIN

4: Booted TWRP

5: Wiped DATA "yes"

6: Flashed Encryption Disabler

7: Flashed boot.img

8: Flashed Magisk 17.3

9: Booted normally, confirmed root (yay!)

10: Restarted, now get this error (boo)

I believe it's because my status is "modified" but RMM is again "prenormal" after wipe.

EDIT: Is it possible that leaving "F. Reset time" enabled is throwing me back into RMM Prenormal? Using the latest ODIN (3.13)

I really do not know but maybe [MENTION=4553200]Mentalmuso[/MENTION] or [MENTION=2313936]suzook[/MENTION] can provide some insight. Once your rmm status is normal and you flash twrp you shouldn't have any issues.

Totally fair. Maybe that step should be added to the list of instructions in the OP?

Are you doing anything to disable rmm? Basically, the Rlc.apk needs to be removed and the line ro.security.vaultkeeper.feature in vendor/build.prop needs to be set to 0

[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] klabit87:
Dm-verity is what Google uses to protect the integrity of the system files. If anything is changed in system, then it will fail to boot.

Dm-verity is disabled when you flash magisk. And is also disabled in my boot.img in the OP.

My boot.img is only necessary because at the time, magisk could not patch it properly so root would not function fully.

I don't know if magisk has been updated to patch it properly without my kernel.

You should always flash kernel first and then magisk since magisk patches the kernel.
