[Guide] Root Note 9 (Exynos) Android 10 (Q) With/Out Custom Recovery

How to Root Note 9 with Magisk on Android 10 (Q) without Custom Recovery (Eg.. TWRP)​
This method will work with most of the latest Samsung devices running Android 9/10. (Tested and Working on Galaxy Note 9 (Exynos) with Android 10 Q).
WARNINGS: I am not responsible for any damage made. Your device warranty will be void. Do it at your own risk.
Warning: Before Installing Magisk
Installing Magisk WILL trip KNOX
Installing Magisk for the first time REQUIRES a full data wipe. Backup before continue.
You have to have your bootloader unlocked before following the instructions
REQUIREMENTS: (Basic knowledge about android rooting.)
Stock Firmware
Odin v3.14.1
Magisk Manager (You can find in Downloads section of Magisk Thread, I used Magisk Manager v7.5.1)
STEP 1 Unlocking Bootloader (This may need to Wipe your Data/Factory Reset.)
Enable Developer Mode on the Galaxy Note 9
To Enable Developer Mode Open Settings option.
Under Settings option, select About phone, then choose Software Information.
Scroll down the screen and tap Build number several times until you see a message that says "Developer mode has been enabled".
Tap on the Back button and you will see the Developer options menu under Settings, and select Developer options.
Toggle the OEM Unlock option on
Then tap on the Turn On button
STEP 2 Patching and Flashing (This may need to Wipe your Data/Factory Reset.)
Download the firmware for your device.
Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
Install the latest Magisk Manager
In Magisk Manager: Tap Install → Install → Select and Patch a File and select the AP tar file.
Magisk Manager will patch the whole firmware file and store the output to [Internal Storage]/Download/magisk_patched.tar
Copy the patched file to your PC with adb pull /sdcard/Download/magisk_patched.tar. Do not use MTP as it is reported to corrupt files. (I have copied with MTP)
Reboot to download mode, and flash magisk_patched.tar as AP in Odin, together with the BL, CP and HOME_CSC files (I have used CSC instead of HOME_CSC). (Never flash only an AP file, as Odin can shrink your /data file-system if you do). Important: Uncheck “Auto Reboot” in Odin Options!
Magisk is now successfully flashed to your device! But there are still several steps before you can properly use the device.
STEP 3 Wipe data/factory reset (This may need to Wipe your Data/Factory Reset. : D)
We now want to boot into the stock recovery to factory reset our device. Full data wipe is mandatory! Do not skip this step.
Press Power + Volume Down to exit download mode. As soon as the screen turns off, immediately press the combo key to boot to recovery (e.g. on the Note 9 it is Power + Bixby + Volume Up). Since we want to boot into stock recovery, continue pressing the volume up button until you see the stock recovery screen. (I had to release power button when Note 9 logo appeared).
Use volume buttons to navigate through the stock recovery menu, and the power button to select an option. Choose Wipe data/factory reset to wipe the data of the device.
This time, we can finally boot to the system with Magisk. Select Reboot system now, and immediately press the combo key to recovery. After seeing the bootloader warning screen, release all buttons so it can boot to the system. (Just select Select Reboot system now)
The device will automatically reboot for the first time it boots. This is completely normal and done by design.
After the device is booted up, do the usual initial setup. The following steps will need an internet connection.
You shall see Magisk Manager in your app drawer; if not, manually install the Magisk Manager APK and continue to the next step. The app would be a stub and it shall automatically upgrade to the full Magisk Manager when you open it.
Magisk Manager will ask to do additional setups. Let it do its job and the app will automatically reboot your device.
Voila! Enjoy Magisk

Yes it works

Guessing this is non snapdragon use only. I don't see any models this works with but root isn't possible with North American note9 as far as I know. The boot loader is locked down.

I don't understand...where, how flash magisk_patched.tar ????

Please edit title to say this is Exynos only

thanks ..

Currently I am not using this System-as-root method to root my device because working version of Dm-Verity & ForceEncrypt Disabler is released so I am using TWRP method to root my device so I can't test secure folder on this rooting method. Now my device is rooted with Magisk via TWRP and secure folder is working without any issue so I think it will work with this method too.

Zer0De8th work perfect root with: twrp-3.3.1-r3.7-q-crownlte.tar, Magisk-v20.3(20300).zip and Disable_Dm-Verity_ForceEncrypt_02.02.2020.zip
Thx very much man!!!

Hello
Thanks to the authors of this tutorial, and others on XDA, I completed a detailed procedure to Root the Galaxy Note 9 SM-N960F under Android 10 with the Recovery Custom TWRP which allows the backup and restoration of all partitions.
This procedure may seem long because it is very detailed because there are very important points not to miss so that the partitions are not locked by Android 10.
I hope the French / English translation is good because I am very bad in English

Here is the new location for CSC feature.xml "/odm/etc/omc/XXX- your country code/conf/cscfeature.xml".
You have to Decode / Encode CSC files use OmcTextDecoder .
Many of the old CSC features don't work on Samsung Android Q

From LineageOS 17 to stock rom

Hello,
On my moto G7+, i have flashed LineageOS 17 two weeks ago. It was running well except that i get LTE data only for one SD slot (b).
I've seen that i should have updated original moto rom till the last update with android 10 BEFORE to flash LOS. I didn't.
I've proceed this flash procedure :
fastboot boot twrp-3.3.1-0-lake.img
In TWRP :
‘Advanced‘ menu.
TWRP on Moto G7/Moto G7 Plus - Select 'Install Recovery Ramdisk' Option
Tap on the ‘Install Recovery Ramdisk‘ option.
Navigate to the phone’s internal storage and select the TWRP recovery image file.
Permanently Install TWRP
Finally, swipe the button to permanently install TWRP.
Once the file has been flashed, go back to the TWRP main menu. Do not reboot your phone into the system yet. Permanently installing TWRP modifies the boot partition and will trigger DM-Verity when the device boots. And thus it will cause a bootloop.
To fix this, head to the next section to flash the Magisk installer zip to root Moto G7 Plus and disable DM-Verity subsequently.
ROOT
Flash Magisk Installer zip in TWRP to root Moto G7 Plus
Select the ‘Install’ button in TWRP recovery.
Navigate to the directory where the Magisk installer zip file was transferred.
Select the “Magisk-v19.4.zip” file.
Tap on the “Add more Zips” button and select the “copy-partitions-AB.zip” file to add it to the flashing queue.
Then swipe the ‘Swipe to Confirm Flash‘ button to flash the files and root Moto G7 Plus using Magisk.
Finally, tap on the ‘Reboot System‘ button to reboot your phone.
So i decided to come back to original last firmware (with android 10). Here begins difficulties.
I tried to run this :
1) RSD lite is not working with my W10 computer
2) Flash rom with BAT file (Flash Rom.bat) > not working
Please, can someone let me know "how to procedure" to come back to stock os ?
Many thanks :good:

I've used Lenovo Rescue and Smart Assistant to restore back to stock.
Put your phone in fastboot mode and the application will detect it and ask if you want to restore.

Any magisk module that can make sd card as adopted storage on Android 10?

Did google remove the option of adopted storage? I don't see it on my SM-T295. I rooted it so I was wondering if there is a Magisk Module that can make sd card act like adopted storage.
Thank you.

Can you tell how did you root your tab please.

Before Installing Magisk​
Installing Magisk WILL trip KNOX
Installing Magisk for the first time REQUIRES a full data wipe (this is NOT counting the data wipe when unlocking bootloader). Backup your data before continue.
Download Odin (only runs on Windows) that supports your device.
Unlocking Bootloader​Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Your bootloader now accepts unofficial images in download mode
Instructions​
Use either samfirm.js, Frija, or Samloader to download the latest firmware zip of your device directly from Samsung servers.
Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
Press the Install button in the Magisk card
If your device does NOT have boot ramdisk, check the “Recovery Mode” option
Choose “Select and Patch a File” in method, and select the AP tar file
Start the installation, and copy the patched tar file to your PC using ADB:
adb pull /sdcard/Download/magisk_patched_[random_strings].tar
DO NOT USE MTP as it is known to corrupt large files.
Reboot to download mode. Open Odin on your PC, and flash magisk_patched.tar as AP, together with BL, CP, and CSC (NOT HOME_CSC because we want to wipe data) from the original firmware.
Your device should reboot automatically once Odin finished flashing. Agree to do a factory reset if asked.
If your device does NOT have boot ramdisk, reboot to recovery now to enable Magisk (reason stated in Magisk in Recovery).
Install the Magisk app you’ve already downloaded and launch the app. It should show a dialog asking for additional setup.
Let the app do its job and automatically reboot the device. Voila!
I have tried this one
I have tried flashing unofficial twrp

[RECOVERY][TB-X505F][UNOFFICIAL] TWRP 3.6.x for Lenovo Tab M10 HD

This version of TWRP works on the Lenovo TB-X505F (wifi).
For the TB-X505X, see this thread. For the TB-X605F/L, see this thread.
For the TB-X606F/L, see this thread. The X606F/L is the second gen M10 and it uses a Mediatek SOC.
Code:
#include <std_disclaimer.h>
/*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you.
*/
Working:
AFAIK, everything is working including:
data decryption
MTP
Known issues:
time not adjusting for Daylight Saving
OTA (for a workaround see this post)
Before installing TWRP
Before you install TWRP, upgrade your tablet to the Android 9 (Pie) or Android 10 (Q) stock ROM.
This tablet shipped with Android 8 (Oreo), in which the bootloader did not allow unlocking. When you tried to unlock the bootloader, it gave this error message:
Code:
fastboot oem unlock-go
FAILED (remote: 'unknown command')
fastboot: error: Command failed
Installation
It is recommended that you also install Magisk. This will ensure TWRP remains your default recovery.
Step-by-step guide
download TWRP to your PC (see the Download section below)
download magisk.apk to your MicroSD or OTG device. Get the latest Magisk apk file here. Rename the filetype from apk to zip (for example Magisk-v22.0.zip)
if your bootloader is already unlocked, go to step 4. To unlock bootloader:
on tablet: go to Settings->System->About and press "Build number" 7 times to enable Developer Options.
on tablet: go to Settings->System->DeveloperOptions. Turn on: "OEM unlocking" and "USB debugging".
connect tablet to your computer. Tablet will ask for permission to "Allow USB debugging". Tick "always allow" and select "OK".
backup any files you want to keep to an external device (MicroSD/OTG/computer), because the next step will wipe all your photos, files, google account etc on the tablet.
Now unlock the bootloader:
Code:
adb reboot bootloader
fastboot oem unlock-go
fastboot reboot
flash the twrp image:
Code:
adb reboot bootloader
fastboot flash recovery twrp.img
if you haven't loaded Magisk yet, go to step 6. If you have already loaded Magisk, you can just reboot and you're finished:
Code:
fastboot reboot
adb reboot recovery
load Magisk (step one): reboot to recovery. Do not reboot into the system, because it will over-write TWRP with stock recovery. If that happens, go back to step 4 and start again. When you issue the reboot command (below), you have to immediately press the button combination to reboot to recovery (TWRP). Here are the steps:
issue the reboot command:
Code:
fastboot reboot
immediately press and hold all three buttons (Pwr+VolUp+VolDown). The tablet might reboot twice. Release all the buttons when you see the TWRP screen, or hear your PC acknowledge that ADB is connected.
load Magisk (step two): flash Magisk. In TWRP:
select "Install"
use "select storage" to locate device you stored magisk.zip on.
press the OK button
select the Magisk zip file
swipe to confirm Flash
when Magisk is finished, hit the "Reboot System" button
finished!
If you prefer to use button combos, rather than fastboot/ADB commands:
Vol Down + Power = fastboot mode
Vol Up + Vol Down + Power = recovery mode

Not that I know of. The bootloader accepts the command fastboot reboot recovery, but boots to system anyway.

Hello there, I've been looking how to install this on my slow tablet for almost like an hour. Could there be some tutorial or extended explanation to the process and installation, I'm such a noob, sorry.

This worked for me. Thank you for your effort and the TWRP!

Worked for me too - many thanks!
Can't wait for a custom ROM!

7. fastboot flash recovery [filename.img]
8. Turn off device
9. Turn on device holding all 3 buttons, release when see Lenovo splash screen
10. In TWRP find Magisk zip
11. Install Magisk
Stock ROM Recovery
1. Download qualcomm drivers 64 bit install
2. Download Lenovo recovery and image tool windows app from Lenovo support website
3. Fastboot oem edl
4. Turn off M10

6. Hold volume up (up is the side of the button closest to the front camera) and insert cable
7. Release button after windows app detects device
8. Troubleshoot by checking windows device manager for the M10 appears as a Qualcomm device

I'm thinking about getting one of these tablets, but before I do so I'd like to know that the screen lock still works after installing TWRP.
This might sound like a crazy question, but my Samsung Tab A won't set a screen lock - pattern, PIN or password - once TWRP has been installed, and I'd rather not run into the same issue again.

Thank you! TWRP is working fine!
Stupid me flashed before I installed the Android 10 OTA, so I had to temporarily go back to stock recovery. Unfortunately beamingbadger's method didn't work for me.
This is how it worked for me:
Download the OTA via Lenovo's "Rescue And Smart Assistant"
The stock recovery image will be in the Download folder (default path: C:\ProgramData\LMSA\Download\RomFiles) called "recovery.img"
Flash the recovery.img the same way as you would with the twrp img (adb reboot bootloader -> fastboot flash recovery recovery.img)
fastboot reboot
Install OTA
Flash TWRP recovery + Magisk again (follow the steps from the first post, skip bootloader unlock)

The method I use to install OTAs is:
open Magisk App
select "Uninstall Magisk", then the "Restore Images" option
reboot to Android (you will have no root access and stock recovery is restored)
apply OTA
re-flash twrp and install Magisk
NOTE 1: if you've unencrypted your data partition, it will be re-encrypted by this process.
NOTE 2: the new Magisk App (v22) can be installed in TWRP by renaming the *.apk to *.zip. See the new install instructions.

What's involved with running gsi ROMs on this device? It's got the same SoC as my Samsung Tab, which runs them well, so I'm assuming that this tab will also, but I'd like to know if there are any traps that I need to be aware of.

I can partly answer my own question. It all went more smoothly than I expected: installing TWRP, Magisk and then LineageOS R Mod //LiR, followed by Disable_Dm-Verity_enfec.zip.
If I want to try other GSI ROMs, do I need to flash stock before trying another one? I've had some trouble doing that (won't boot) and it's possibly to do with encryption.

On my X605F I do this in twrp for a new GSI install:
format (not wipe) data partition. This is the option where you have to confirm by swiping.
factory reset. This clears the caches.
restore the stock boot and vendor partitions (from a backup I made). This is because Magisk can touch these partitions.
install the GSI system image
install anything else I need like disable_Dm-Verity, Magisk, gapps etc
I don't know what LOS R Mod //LiR does to your system. If it touches any other partitions, you should restore those to stock too.

Thanks for that. It gives me something to go on with. I've downloaded the stock ROM from lolinet, so I can grab the boot and vendor images from that.

I was able to try a couple of other GSI ROMs and I've settled on AndyYan's LineageOS 17.1 for now. The only serious installation issue I had - which I can laugh about in hindsight - was thinking I'd got myself into a very bad bootloop, when all I needed to do was let go of the power button after the Lenovo logo appeared.
On this tablet, there is no navigation capability at all (no navbar, no gestures, no setting to configure them) on installation, and I have to set it using adb. I suspect it goes back to PHH basic ROMs, but I don't feel like doing yet another install and testing right at this moment. Is this happening on the other tablets that you're testing, or is it unique to this one?

I just posted the v3.5.1 update to twrp.
It's also changed to landscape mode, as many of you requested.

Quick question, how do i apply new system updates with twrp installed? Should i not bother? Also, i forgot how to block check for updates!

will this allow flashing of stock roms download from lenovo recovery? ive been stuck on an ancient android 9 version because the ota updater fails.

[HOW TO][SM-G900X] crDroid 7.20+ or LineageOS 18.1+

As you know, you need to upgrade the modem and radio firmware from 6.0.1 Android version to make the latest LineageOS or other ROM to work.
You can't do this for this specific device, SM-G900X (Galaxy S5 Live Demo Unit), as the ODIN will fail to flash the files.
But you can modify the ROM to make it past boot-loop quite easy.
Here's what you need to do in order to make it work:
Install latest TWRP for TWRP for KLTE;
You can do this with both ODIN or direct upgrade using TWRP image inside TWRP;
Boot into the TWRP;
Load a ROM .zip on the device like crDroid;
You can upload to SDCard using USB while on TWRP;
Wipe everything (except Internal SD Card);
Install the ROM;
Check if it boot-loop;
Now you need to fix the ROM, which is quite easy:
Boot back into the TWRP recovery;
Go to: Mount -> System (check);
Go back;
Go to: Advanced -> File Manager;
Navigate to: /system/vendor/lib;
Delete or rename: libsec-ril.gsm.so, libsec-ril.usc.so, libsec-ril.vzw.so;
Reboot and enjoy .

what if those files are not present in vondor/lib folder and still is boot loop
G900X is on snapdragon or exynos?
