[Root][SM-T380][SM-T385] Samsung Tab A 8.0 (2017) Root Tutorial

Method was kindly shown to me by user Mefody in answer to a thread I posted.
Rooting SM-T380/T385 via Magisk Manager APK v.5.5.3 & Magisk 15.2:
1. Unpack stock firmvare ***.tar.md5 that is currently installed on your tablet (they MUST BE the same!!!).
2. Then unpack AP-block from step 1 to obtain "boot.img" file.
3. Download & install on tablet Magisk Manager APK.
4. Put "boot.img" on SDCARD.
5. Run Magisk Manager, in setiings set "Patch kernel", then setup the Magisk zip (Wi-Fi must be connected to Internet ).
6. When asked, point Magisk Manager to place on SDCARD where "boot.img" saved.
7. After some time You will get "OK".
8. Find on SDCARD file "patched_boot.img". Copy in on PC & rename to "boot.img". Then archive it to "<any name>.tar".
9. Set tablet to download mode & flash above tar-file via AP-slot of Odin-programm.
10. Tablet will reboot & ask to wipe all data to factory's params. Do it... Be noticed, that all passwords, setting, google registry will be wiped.
11. After wiping & rebooting install Magisk Manager APK again... And YEAH!!! You got root!

Thanks for creating this thread. I used the original thread to root my tab, so seeing this as its own thing will be helpful to a lot of people.

Yes... Game Tuner installs & wokrs good.

Could you clarify on these two steps?
1. Unpack stock firmvare ***.tar.md5 that is currently installed on your tablet (they MUST BE the same!!!).
2. Then unpack AP-block from step 1 to obtain "boot.img" file.

You have to open the stock firmware with an archive manager like WinRar or 7zip. Inside you should find an AP-Block folder. Inside of that should be your boot.img file

Thanks, where can I find the stock firmwares?

Here is another problem
Is OEM unlock in Developer Section required to install patched kernel and TWRP with Odin?
I can't find it even it's updated.

Does anybody know if this rooting method will work with T-585 on Android 7.0 (January 2018 update)? I guess KNOX will be triggered, right?

I say the root is TOTALLY FALSE!!!
I have been waiting for two week and there's no update to enable OEM Unlock option.
I have returned the unit with restocking fee.

Have you tried this method even without the option in developer settings to OEM Unlock? On my SM-T350, I don't have the option to OEM unlock either. But I can still root and install TWRP anyways.

I tried to flash modified kernel or TWRP with Odin and I got error
Only official software can be installed.

Perhaps someone could provide boot.img files and links here?
I for instance found no matching firmwares for mine. The one that had both matching versions numbers, said it was for Cellular US. This is a wifi only model. Confused
Thanks

I have that original boot.img and magisk modified one.

There's a 7 days waiting period after you turned it on the first time regardless reboot or not.
I will make a instruction how to root and I will post kernel and modified kernel.

I didn't realize it was so effortless to pull the boot.img out. BUt, until I have that oem unlock option in there, doesn't matter.
Come on, 14 days

Finally, mine has successfully rooted with Magisk.
I will post a guide.

When I try to flash the archived boot.tar via Odin it just hangs and sits there. Any help would be much appreciated. Thank You.

The only way we can get it ported is if we find an Android 9.0 with the same chipset (Very unlikely) but keep your eyes peeled and let me know if you find one

Have tried to install, but I can't, I have followed this steps:
1. With ODIN, I have installer this file: I9506XXUDOD3_I9506NEEDOD4_I9506XXUDOD3_HOME.tar.md 5.7z
2. Then, I have booted my device, and then Installed TWRP with ODIN.
3. Then, I copied the ViPER4Android and JamesDSP folder into the root directory of my phone.
4. Then, I did a boot backup, and copied the RESTORE ALL PARTITIONS Folder into the folder where the other backup folder is.
5. Then, I Restored the RESTORE ALL PARTITIONS backup, and then I bootes into the system again.
Idk if I'm forgetting to do some step that is in the tutorial, but I can't find the way to install this I'll be very pleased if someone helps me.
thx in advance

What is currently on the GS⁴ you plan to install this on? Is it custom or is the latest stock build on it?
EDIT: go ahead and flash the stock image provided in my zip. Then after it reboots to stock revocery and does its little thing immeadiately boot back into stock revovery and format /data after that reboot to download and flash twrp. Go ahead and re setup the restore of the all partitios 7z now when you do a restore unclick all the options and restore only the EFS partition then reboot into the still unbooted stock image you odin flashed. Make sure cellular wifi etc works (If the downgrade was unsuccessful then some of those will break) if the downgrade was unsuccessful then do the same thing above except omit the EFS restore and instread boot after you factory rest in recovery.

[NOOB’s][DETAILED] [GUIDE] TO Backup/Restore Stock+ Unlock Bootloader + TWRP + ROOT

A/A & Welcome,
READ THE FULL GUIDE OR YOU CAN LAND IN TROUBLE
Ain't gonna work on pie official
AND DO PRESS THE THANKS BUTTON
Disclaimer
* Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or anything that happens to your device
INTRO
This is a full guide for unlock/relock, install TWRP, Root your device and backup/restore stock OS. Each and every step is explained thoroughly with pictures and videos.
I have ASUS Zenfone Max Pro M1 (6GB variant) (X00TD) (ZB601KL), so I can’t test for other variants. Please report back issues, corrections, omissions, etc., though the guide should work for all devices.
THINGS TO KNOW (IMPORTANT)
~Every text written in double quotes “” means the same written without the quotes.
e.g.:- “abcd” means abcd
“zxcv” means zxcv
They (“”) help to separate usual text from the other text (like a command, file name, etc.)
~If you have not enabled file name extensions then you will see files without their extension and vice versa
e.g.:- “filename”, “mypicture” in 1st case
“filename.extension”, “mypicture.png” in 2nd case, respectively.
~Boot Partition or Bootloader:-This is the partition that enables the phone to boot. Without this partition, the device will not be able to boot.
~Recovery Partition:-Recovery partition lets you boots the device into a recovery mode to perform recovery tasks.
~TWRP: - stands for TeamWin Recovery Project. It is a custom touch recovery that is GUI based.
~Flashing: - simplest: - installing
~Fastboot Partition: - lets us reflash partitions. (On device)
~Fastboot: - is an executable used to reflash partitions. It comes with the Android SDK. (On PC)
~Rooting: - an Android phone lets owner edit system files. Thus enabling various tweaks and use of apps that require root access.
~Device driver: - determines how PC will communicate with a device.
~Unlocking/Relocking:-With a locked Bootloader, booting into custom things is not allowed is not. Unlocking lets us do so.
~Reboot: - Switching ON AND OFF (in simple terms)
Requirements
MIND, PC, USB Cable, Internet, Fully charged PC (Windows OS), and obviously Asus Zenfone Max Pro M1
The Real Steps From Here
FOLLOWING THIS GUIDE YOU WILL PROBABLY LOSE ALL THE DATA ON YOUR PHONE SO MAKE A BACKUP FIRST (Don’t worry it’s in guide too)
STEP 1. Downloading all the necessary files
a. Here are 2 zip file with everything you will probably need following the guide :-
basic zip
extension zip
. I have tested the procedures using these files only so maybe other versions might not work. A “guide.doc” with the same text as in here (on XDA) is also present. It will be of great help if you don’t have internet connection in PC.
The basic zip file contains minium files needed.
The extension zip file contains the TWRP recovery(then one used in the guide),guide.docx ,and the videos used here too.
Copy the twrp file to unlock folder of extracted folder.
b. Extract the zip file above.
First download the zip file and Copy to PC
Then Right Click on it
Then click “Extract All”
Uncheck “Show extracted files…”
Click on “Extract”
The folder “zip” will be extracted
Done
This “zip” folder will be called extracted folder in the guide video link to extract zip
To download most up to date version of the files go to links present at last
STEP 2. BACKUP
a. Use an apk backup tool to backup app installers
VIDEO TO BACKUP APP INSTALLERS
b. Some APPS like Whatsapp, etc. have backup to drive function use that
VIDEO TO BACKUP WHATSAPP CHATS
c. Backup SMS AND Call Logs
VIDEO TO BACKUP CALL LOGS AND MESSAGES
d. Copy each and every file from you internal storage to PC.
Video to backup each file to pc
DONE
Step 3. UNLOCKING BOOTLOADER(Data will be wiped)
2 options:-
A. Official Method (NOT TESTED): -
In extracted folder go to “unlock” folder then “Official” folder. Install the “UnlockTool_9.1.0.3_180621_fulldpi_signed_ZB601KL.apk” in Asus and follow the steps from there.
B. Unofficial Method (Tested):-
a. Installing Drivers
Connect phone using USB cable to PC
Right click on This Pc
Go to “Manage” > “Device Manager” Or Just search for “Computer Management”/“Device Manager”
A list will appear.
Find your device (best way to do so is by disconnecting/connecting the device and notice the changes accordingly in the list)
Now right click on it>”Update Driver Software”>“Browse my computer for driver software”
Now either enter path of the driver folder or click on browse and navigate to the driver path from there.
Press Next OR
“Let me pick …”>and select the driver
video to install driver
The drivers have been installed
b. Booting into FASTBOOT
Switch Off the Phone
Hold the Volume UP and Power ON Button Simultaneously
Device buttons labbled image
You will see this on your phone
image of FASTBOOT screen
c. Unlocking Bootloader
Now connect phone using USB cable to PC
Look for the “unlock” folder in the extracted folder.
Open it
Find “unlock.cmd” or “unlock” file
(Or “unlock no erase.cmd” to keep data {not tested})
Open it
Done
d. You will see some messages in yellow/brown/white colour on your phone
You will most probably see “encrypting your device”, “warning Bootloader unlocked” messages, let phone do its work and don’t interrupt it, and keep cable connected. Phone might reboot too. The phone will at last boot into stock OS and you will see the device setup screen.
image of the warning message
e. Now if you wanted TO ONLY UNLOCK BOOTLOADER THEN THE JOB IS DONE, long press power button. If you want to root or flash TWRP then continue (Tested method to root requires TWRP flashing or you can try the untested method to root only)
Step4. Installing/Flashing TWRP
TESTED METHOD
a. Connect phone using USB cable to PC
b. Don’t setup your device just now because possibilities are you might lose the data again
c. Boot into fastboot mode
d. Open the “unlock” folder in the extracted folder.
Now Two Different ways to opt for from here:-
i. THE LAZY METHOD (Tested)
a. Open “flash_recovery.bat” or “flash_recovery” in the “unlock” folder of the extracted folder.
b. You can flash the tested or any other recovery using this script.
c. Follow the steps from the script
video of how to use the script
d.Then go to step of Flashing ZIPS of The Manual Method
e. Done
OR
ii. The Manual Method (Tested)
a. Keeping Shift Key pressed, right click {with mouse} in the blank white space of the “unlock” folder’s explorer window.
b. From the menu select “open command window here”
c. A CMD window will be opened
open cmd video
d. Now type “fastboot devices”
e. See if your device is connected. You will see something like this
f. Now type “fastboot flash recovery twrp-3.2.3-0-X00TD-20181024.img”
If you want to flash any other recovery instead of “twrp-3.2.3-0-X00TD-20181024.img” write the file name of your recovery file. Make sure it’s in “unlock folder”. Though this recovery is the only tested one (by me).
g. Now keeping the phone connected to PC, boot into TWRP/Recovery by pressing the Volume Down and Power ON Button Simultaneously.
h. The usual warnings, messages and recovery boot screen will flash:-
warning image
twrp flash screen image
i. It may take some time to load so wait for at least 2 minutes.
j. Now if touch is not working press power button 2 times (on and off the screen)
video showing how to enable touch in twrp
k. If it shows “Swipe to Unlock” do so. If it shows “Swipe to Allow Modifications” then wait and continue reading …
swipe to allow image
swipe to unlock
l. “Swipe to Allow Modifications” means you allow TWRP to modify system. This will make sure TWRP remains in the phone and not just vanish after a reboot but it also means you will have to flash some other files to be able to boot into stock rom back.
m.
2 ways from here:-
i. Now after swiping, Decrypt Screen will appear just press cancel.
decrypt screen image
OR
ii. If you have data on the device then enter pin/password or try default_password.
If you had kept pattern then either go back and change it or try this:-
1 2 3
4 5 6
7 8 9
these no’s correspond to pattern dots.
Say you kept pattern “third row left to right” then the password is 789 .
If all these fail then you will have to lose your data.
n. As we don’t have any precious data in our phone we will (or you are compromising)
Press “Wipe”
Press “Format Data”
TYPE “yes”
Press “tick” or “enter key”
Done
wipe data video
>Flashing ZIPS
o. Now Copy these 2 files
i. “decrypt.zip” or “decrypt”
ii. “Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip” or “Disable_Dm-Verity_ForceEncrypt_12.16.2018”
From extracted folder to your phones internal storage.
p. Go to Install>select the zip>swipe to flash (flash dm_verity… then decrypt…)
If you don’t see your device storage connected then try reconnecting using USB cable and also check if MTP is enabled.
enable mtp video
>Done
Want to root? Then continue…
or >
Now reboot to system Go to Reboot>System
video to show how to rebbot to system in twrp
Step 5. Rooting
We will be using Magisk to root you can use any other method but this is the only tested method.
a. Copy “Magisk-v18.0.zip” or “Magisk-v18.0” to your phones internal storage from extracted folder.
b. Go to Install>select Magisk…>swipe to flash
Done
c. Now reboot to system Go to Reboot>System
reboot video
e. To use Magisk properly you may need to download latest apk. (Link at last)
Step 6. Relock (NOT TESTED)
a. Connect phone using USB cable to PC
b. Boot into fastboot mode
c. Open “Relock” folder from extracted folder
d. Open “relock.cmd” or “relock” file
Done
Step 7. RESTORING
a. First setup the Device again
b. Copy each and every file back to the phone storage
c. Now to restore messages see the restoring part of this video here
d. WhatsApp messages will be automatically restored after you install the app with same number as before.
Tips
After rooting don’t just go on and flash a custom rom. Take a backup first (of all partitions) using TWRP and keep it safe somewhere so you won’t need to find unbrick tutorials later. Plus you will have your most stable and tailored rom with you.
Also don’t just go on and flash xyz mod. Research and then Flash.
Magisk is our best friend. It lets you do modifications without hurting the system. The Magisk modules are most safe mods as they can be reverted back easily.
And don’t just go on and debloat stock OS. In Magisk there is a module called Debloater use that. You can easily revert back if anything goes wrong.
Other good Magisk modules: - Energized, Systemizer, MidnightCore & Advanced Charging Controller (acc) but do read their XDA guides first.

Thanks for the help.
I'm running into some problems while installing the driver software on my Windows 10 laptop. It shows Error 10 this device cannot start.
I tried to uninstall and reinstall the drivers, rebooted my pc on every step, tried to install while connected to my phone, but nothing seems to work.
I've installed the Pie Beta for Asus Zenfone Max Pro M1 (not sure if this is causing it)
Is there a solution to this problem?

I am currently on Beta Pie...will these methods work for bootloader unlocking and TWRP, custom rom flash ???? I just wanna use PE/Havoc OS rom...no other tweaks or root

thanks its working

I updated to pie beta and I think this guide is not working for that, because when flashing twrp. I'm getting 'request download size is more than allowed size' and I tried every way possible to solve it. But no luck Hope you can help me with it, or maybe it'll work after stable version?

You need to have some basic knowledge
Always have the correct software and backup all your data.
o Also download before you start the stock files, so that you are able to quickly reverse everything via: sammobile
Remember to backup your data!!!!
If you have trouble and the tablet is not working flash the firmware which you’ve downloaded via odin
Working ROMS (Which I’ve tested so far):
IF you want to install a custom ROM, you need to choose the correct custom ROM
Choose the ARM 32-bit with 64-bit binder AB (also known as A64B).
LineageOS 17.x GSI here
Legion ROM GSI here
From OEM stock firmware:
Download TWRP https://forum.xda-developers.com/ga...rp-3-3-1-2019-galaxy-tab-10-1-t3934805/page35
Unlock bootloader
Hold Vol Up & Vol Down buttons during restart to enter Download mode
Install TWRP to AP with Odin
Hold Power & Vol Up buttons during restart to enter TWRP recovery
Install latest Multidisabler from TWRP

Reboot to system
Check if OEM unlock is enabled in the developer settings (it should be enabled and greyed out) IF so yeey you did It. If not start over.
Install custom ROM:
Well installing a custom Rom is quite easy .
Download a GSI ROM you like and put it on a SD cart
Go into TWRP
Select “install”
Click on “install image”
Click the on the ROM
In the next screen where we need to select the partition, select the “System Image”
Swipe to confirm
If you want ROOT and or install GAPPS follow the extra steps bellow. If NOT, just reboot the system
Extra’s install MAGISK and or install GAPPS
First of all download the files you want.
Magisk: here
GAPPS: here
You want root? You need to prepare the TWRP image yourself, simply use Magisk Manager to Select and Patch a File. Which we can prepare and flash after you finished the setup of the tablet. You need more info check the following: link
Go back to the TWRP home screen
Select “Wipe”
Select advanced wipe
Check “system”
Click on “repair or change file system”

o You should see “resizing… done.”
Go back to the TWRP home screen
Select “install”
Select the zip file(‘s) you want and flash them
o IF you receive an error if you want to install the GAPPS zip like “not enough space” go back and resize the system partition
o IF you receive an errro if you want to install Magisk, go back and resize the system partition
Remove “dalvik and cache”
Reboot system
Setup your tablet
Now for the last step to root the tablet all the way
Go into Magisk manager
On the Magisk dashboard you’ve should see that you have the latest version of magisk. Press on the “install” button at the right side
o Select “Select and Patch a File” select the TWRP IMG you still have on the SD card
o Magisk should create a “magisk_patched.img”.
If you have the “magisk_patched.img” go into TWRP and flash this IMG over the recovery
o Install
o Select “install image”
o Select the “magisk_patched.img”
o Flash it over the “recovery”

Hi,
Thanks for the guide. Which ROM you recommend? Everything working for you (LTE modem etc)?
Can you now install 64bit apps from Google Play? Any chance you can check if the DJI Fly app is working on your SM-T515?

Well, It's still a 32bit rom. I've tried to install the app but I'm unable (prob because the app is 64bit)
Everything works fine, I'm running the lineageOS ROM. I have a data bundle and I'm able to internet with it (if I want )

Sorry if this is a stupid question , but before i brick my new SM-T515 I would rather ask the experts.
Now, i have rooted the stock ROM folowing the steps in https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root with no TWRP and want to install one of the custom ROMs you have tested.
will I lose root if flash the Legion ROM GSI?
if yes, can you please put some steps together to root and install TWRP?
i still have the “magisk_patched.tar" from the stock ROM, would that work for the Legion ROM GSI?

In theory it should work. I've already covered "root" also in the guide

I've followed the steps and have Lineage installed on my T515, but when I plug it into my computer it can't see the Tablet in Windows Explorer. I've set it to MTP mode and enabled USB debugging. Strange thing is when I use ADB DEVICES I can see it. Also when I plug it in, the tablet makes a sound and it says 'Usb Debugging...' on screen. It just won't show up in Windows.
Also when I try and use File Explorer on the tablet, it can't see the SD Card. I've tried formatting it for 'Portable' but it when I go back in it says it corrupted. When I format it for Phone Storage, it shows the extra space for the phone storage but I also can't see it in the File Explorer.
Anyone else come across this?

I haven't found one yet, I'm going to try go back to Stock as I need my computer to be able to see the tablet to transfer files over. I've tried installing the Legion custom rom and it does the same thing. I'm not sure but I'd love to get an answer to this and I'd love to use a custom rom.
Are there any other Android 10 roms that I could try?

I have a work app that need a little more ram: the solution is LineageOs (used 1,2gb vs 1,5gb of the stock rom) and I transfer files through recovery. I tried LegionOS but is full of bugs and file transfer doesn't work the same.

I'm back to stock and my computer and can see my table and the SD card is working fine. Its a shame as I'd love to use LineageOS but for now I'm stuck on stock.

I don’t know what I’m doing wrong so need some help please. I’ve installed TWRP and multidisabler. I’ve wiped the system cache data etc like I was flashing a custom rom.
I’ve downloaded the rom from the links flashed it via system image but I still get the message no os installed rebooted and just a bootloop saying unlocked boot loader press power button to start then nothing no booting image from linageos. Just repeats.
Can anybody tell me or guide me on what I could have done wrong and what what I should being

Because there must be a mistake in making.
Also to what I’ve been reading is that I need something of treble enabler for the device but I really don’t know.

I finally managed to get LineageOS installed. I just deleted all the files and redone loaded them, returned back to stock and did the whole process all over again.
And it worked. ? ? so maybe somewhere down the line put have been a corrupt download or something.
Custom rom has whole different feeling on the tablet now. Thanks again for tutorial, I’ve been waiting for something like this for a while.

Solved - Boot S10 into rooted ROM without requiring 3 buttons pressed

I have purchased my Samsung S10 Exynos and successfully rooted it using the only possible ways that have seems to be available so far. I have gained root, but I was wondering if anyone has solved the issue of having to turn the device on with all 3 keys held down at the same time. I understand that this is because the rooted version of the phone has be installed on the recovery of the phone, but I hope that there becomes a way to turn on the phone with root and use only the power button. I check from time to time, but it seems that this has not been solved yet. If anyone can find a solution for me so that I do not have to keep searching then I will reward them $100. An idea that I had is if there was a way to modify the power button to boot into recovery by itself? I believe this would be impossible but if anyone could think of a way to do that then that would solve the problem. I am okay with never being able to unroot the device if this would be the case.

How often do you cold boot?
reboot:
- Magisk boot menu
- adb reboot recovery

Hello, thank you for the suggestion. I thought about that idea already and I forgot to mention it in my post. I am looking for a way to do it via a cold boot. I know about the reboot into recovery method already, and I know of a way to map the power button to reboot into recovery if held down, but I am looking for a way to cold boot into recovery with just the power button.
I like your idea, but if there was a way to do it as a cold boot then that is ideally what I'm looking for. Your method would work if there was a way to just keep the phone shut down and wait until I hold the power button to turn it on and then it boot into recovery. If you can think of a way to do that then let me know.
The reason I am seeking this is because I root the S10 out to have a proprietary app on it and the app requires root to function properly. I need the power button to boot with root on the S10 so that it will always do so and my employees / customers will not access the non-rooted side of the phone by accident. The 3 button combination is too difficult, so I would need to resort so either a S8 or S9 if the S10 won't allow power button only to boot with root access. The app that I make uses a great amount of battery life so I need the ability to shut down the phone and cold boot it back into recovery. Thanks.

Hi, I assume you have rooted using the magisk-patched-recovery method (patched AP file) and if memory serves and from what I am re-reading this method does require the 3-button-combo to boot to rooted system.
When I first got my s10 and rooted this was the only method at the time, but then came custom kernels with built-in magisk.
With this method from power menu if I...
- reboot, phone will reboot to rooted system.
- power off, the power on button will boot to rooted system.
In fact I'm not sure how/if I can boot to non-rooted system with this method.
I currently on custom rom AmbasadiiRom 2.2 with AmbasadiiCruel Kernel G97xF-v3.10.
There are a few custom kernels that have built-in magisk. You will have to check rom compatibility but believe they work on samsung stock based firmware/roms, AmbasadiRomi is based on stock firmware.
- Cruel Kernel
- ThundeRStormS kernel
If you like I can provide a step-by-step, but you will lose all data as it will require flashing stock unpatched firmware, unpatched twrp in odin then custom rom (optional - depending on if the custom kernel does work on stock firmware) & custom kernel.

Awesome. Your solution sounds perfect for what I was looking for. Yes, I got my S10 back over a year ago and rooted it with patched AP file and magisk. I was only able to find that method even up until yesterday. I would like a step by step if you are able to quickly put one together. If it works then I am glad to grant you the reward for your help. I am willing to do this in the easiest way possible, even if it requires wiping data. I never used the phone so wiping is no problem at all. I am looking to do this to several devices so the easiest and fastest way would be the best. I will look into your comments and see if I can figure out doing this over this weekend. Will keep everyone updated.

I just read some info on the links you provided and i think i can figure it out. if i have any trouble then ill let you know. Dont worry about a step by step for now unless I have any trouble. Thanks!

Here is a bit of a step-by-step for Samsung s10 Exynos Model:SM-G973F
Info below is based on using December Security patch: 2020-12-01 firmware G973FXXS9DTK9 (Android 10) and Ambasadii Rom
NOTICE: The easiest and fastest way would probably be flashing kernel with stock firmware/rom. I have only done custom (but stock based) roms with kernel so am assuming the steps (5a.) for stock firmware/rom, you may want to post in chosen kernel thread to confirm if those steps are correct.
- both kernels I mentioned say they are compatibly with stock roms & AmbasadiiCruel Kernel is based on Cruel Kernel so I assume that would also work on stock rom.
This assumes you have already unlocked your bootloader, if not check this Recovery thread under Instructions: Odin (windows) - steps 1-6 for how to unlock bootloader.
1. Download all files needed to pc.
- Current latest firmware G973FXXS9DTK9, I use frija tool as downloading from samfirmware.com is very slow.
Enter Model, CSC, check the auto box & click check update and download.
Once complete unzip with 7Zip or preferred zip tool.
- In Recovery thread download latest twrp for device, is this case for S10 G973F latest twrp is - twrp-3.5.0_9-1-beyond1lte.img.tar
Under Instructions: Odin (windows) download
- Odin v3.14.1
- avb disabled vbmeta.tar
- click link to multidisabler-samsung-2.* and download latest version from there, currently multidisabler-samsung-3.1.zip
If sticking with stock and custom kernel
- easiest one looks like it would be Cruel kernel or AmbasadiiCruel kernel.
- check kernel thread of choice for compatibility with stock firmware and specific install instructions.
For custom rom in this example for Ambasadii rom
- Download files from Ambasadii rom site
- ROM.G97xF.XXS9DTK9-v2.2.by.ambasadii.zip
- mods_DTJA-v1.3.4.zip
- magisk_safetynet_fix.zip
- AmbasadiiCruel-G97xF-v3.10.zip (rom does include previous kernel 3.9 but this one is updated to latest magisk 21.2)
Bootlogo patcher - this will get rid of the warning about bootloader being unlocked when booting phone. (optional)
TWRP_Bootlogo_patcher.zip
Copy the below files to phones external SDCard
- multidisabler-samsung-3.1.zip
- TWRP_Bootlogo_patcher.zip (optional)
- chosen kernel zip - if sticking with stock
Custom Rom files

- mods_DTJA-v1.3.4.zip
- magisk_safetynet_fix.zip
- AmbasadiiCruel-G97xF-v3.10.zip
2. Flashing stock firmware - Odin
- Open Odin on pc
- Turn off the phone
- Use vol down + bixby, then connect usb cable to phone from pc to start the phone in download mode, press vol up to confirm and go to download mode.
- In Odin under log you should see added, I also like to turn off auto reboot under the options tab and do manual reboot once complete but that's up to you.
- Add BL, AP, CP & CSC from the unzipped firmware downloaded in step 1. The AP & CSC can take a little time as they are larger files.
- Once all files added click start and wait until complete, you should see SUCCESS in the top left area once done.
- If you turned off auto-reboot then unplug usb and do manual reboot by pressing vol down + power for 7 seconds, else phone should reboot automatically then unplug.
3. Once phone boots up
- complete setup and connect to Wi-Fi or data
- skip adding Google & Samsung accounts.
- enable developer settings & check OEM unlock is on.
- turn off the phone.
4. Flashing TWRP Recovery - Odin
- In the Recovery thread under Instructions: Odin (windows) continue on from step 8 including formatting data and flashing multidisabler zip which you copied to SDCard.
- in twrp go back to wipe and select advanced and wipe data, cache & dalvik-cache
5a. If sticking with stock & custom kernel - Read NOTICE at top of post
Assumed Steps
- Still in twrp recovery go back to main menu
- select install and flash kernel zip, then TWRP_Bootlogo_patcher.zip
- Not sure if magisk_safetynet_fix is needed or works on stock, would need to confirm in Ambasadii thread.
- go back to main menu and select reboot & system
- give the phone a few minutes to start, and then complete setup including adding your accounts.
- once setup is complete open magisk and it will run additional setup, and then phone will reboot
- done
OR
5b. If flashing Custom Rom & Kernel - steps below for Ambasadii Rom
- Still in twrp recovery go back to main menu
- select install and flash ROM.G97xF.XXS9DTK9-v2.2.by.ambasadii.zip, choose options in aroma - once the install is complete exit back to twrp recovery
- select and flash mods_DTJA-v1.3.4.zip, then magisk_safetynet_fix.zip, then AmbasadiiCruel-G97xF-v3.10.zip, then TWRP_Bootlogo_patcher.zip
- once you have flashed all files go back to main menu and select reboot & system
- give the phone about 8 minutes to start, and then complete setup including adding your accounts.
- once setup is complete open magisk and it will run additional setup, and then phone will reboot
- done
6. If you went with Ambasadii Rom
- you will then notice status bar icons are pushed to the right behind the camera
- open rom control, grant superuser rights
- select status bar/options and play around with notch adjustments and positions
- can be a little confusing to start but play around and you'll get the hang of it.
Hope this info helps, let me know if you need any clarification/detail to any of the steps
Also no need for reward, happy to help

Here is a bit of a step-by-step for Samsung s10 Exynos Model:SM-G973F
Info below is based on using December Security patch: 2020-12-01 firmware G973FXXS9DTK9 (Android 10) and Ambasadii Rom
NOTICE: The easiest and fastest way would probably be flashing kernel with stock firmware/rom. I have only done custom (but stock based) roms with kernel so am assuming the steps (5a.) for stock firmware/rom, you may want to post in chosen kernel thread to confirm if those steps are correct.
- both kernels I mentioned say they are compatibly with stock roms & AmbasadiiCruel Kernel is based on Cruel Kernel so I assume that would also work on stock rom.
This assumes you have already unlocked your bootloader, if not check this Recovery thread under Instructions: Odin (windows) - steps 1-6 for how to unlock bootloader.
1. Download all files needed to pc.
- Current latest firmware G973FXXS9DTK9, I use frija tool as downloading from samfirmware.com is very slow.
Enter Model, CSC, check the auto box & click check update and download.
Once complete unzip with 7Zip or preferred zip tool.
- In Recovery thread download latest twrp for device, is this case for S10 G973F latest twrp is - twrp-3.5.0_9-1-beyond1lte.img.tar
Under Instructions: Odin (windows) download
- Odin v3.14.1
- avb disabled vbmeta.tar
- click link to multidisabler-samsung-2.* and download latest version from there, currently multidisabler-samsung-3.1.zip
If sticking with stock and custom kernel
- easiest one looks like it would be Cruel kernel or AmbasadiiCruel kernel.
- check kernel thread of choice for compatibility with stock firmware and specific install instructions.
For custom rom in this example for Ambasadii rom
- Download files from Ambasadii rom site
- ROM.G97xF.XXS9DTK9-v2.2.by.ambasadii.zip
- mods_DTJA-v1.3.4.zip
- magisk_safetynet_fix.zip
- AmbasadiiCruel-G97xF-v3.10.zip (rom does include previous kernel 3.9 but this one is updated to latest magisk 21.2)
Bootlogo patcher - this will get rid of the warning about bootloader being unlocked when booting phone. (optional)
TWRP_Bootlogo_patcher.zip

Hey There, Been busy lately and I haven't gotten around to trying any of these methods until today. Today I attempted the stockrom+CruelKernel. I am having a strange problem. I am acquiring root but as a read-only. I can not make any changes to system files, I can only view them. Can you tell me if you are able to modify or add to the system directory? Let me know. I know your phone is running custom rom + custom kernel, so I just might have to do that if that is the only fix. I have tried several things and read all of the threads but can not find anyone else that is experiencing this issue / I can not find a fix. I'm about to try the custom rom (stock based) + custom kernel to see if that works. If you can tell me if you have access to read/write system files then let me know so I know if this is even possible. Thanks.

I have found out that I can modify system files through twrp recovery, but when I boot into the main operating system then I have root but as read-only.

Hey, sorry for late reply - ever since xda updated it's not sending me emails when I get a notification.
As for the system directory being read-only, I believe this is normal even with root. Root just gives access to the /root dir that you would not normally have without it.
- my system dir permissions by default are 755/rwxr-xr-x
After a bit of searching looks like there are a few ways to change permissions
- twrp, can mount system as r,w - but as you said this reverts on reboot
- adb shell, and chmod permissions, same why you do with linux
- in android using either root explorer or x-plore, haven't tried root explorer as it is a paid app but did test with x-plore and working fine.
check this vid on changing the root access to superuser+mount writable which allows for changes in read-only folders and how to set permissions for files/folders.
I not sure if changing permissions on the system folder itself is safe or would cause any issues, I just created a folder within system and set permissions to 644 reclusive, created some files and rebooted - created folders/files and modified permissions remained fine after reboot.
If you need write permissions in system to install apps as system/app you may find this magisk module useful, it's called App Systemizer which allows you to use apps as system apps systemlessly. Just search in magisk modules.
Hope this helps.

Cool, I'll give your suggestions a try. I'm a fan of ES File Explorer. They have a root explorer built in their app and previously I had a S8 Exynos and a S9 Exynos and that app worked for those phones but with this S10 the switch is grayed out and no other app is working for me either. On my older S8 Exynos and S9 Exynos I rooted with stock-rom + stock-kernel and just needed TWRP+Magisk and I always was able to modify or add/delete system files with ES file explorer. I guess Samsung is getting more and more strict on allowing this by making us hop through more hoops in order to do so. So far I only have ready only system files on the S10 Exynos which is new to me because the S8 and S9 always allowed modifying system files in the past but I will try your methods you suggested. Worst case I'll attempt the custom-rom + custom-kernel and see if that works. Right now I have stock-rom+custom-kernel. I was able to make changes in the system files in TWRP but hopefully your method will allow me to edit system files without having to switch to TWRP every time I want to change something. I will keep you updated.
On a side note I just rooted a Samsung S20 Exynos and turns out that the system files are read only everywhere whether in TWRP or not, so Samsung keeps making things more difficult on us all. I currently have no way of modifying system files on the S20 no matter what I try but that phone is still much newer so I will give the magicians more time before I look into the forums more for that phone. Right now if I can get the S10 Exynos then I'll be happy.
I'll let you know how things progress. If I get what I need done with this S10 then I am happy to give you a donation for your help in this matter. I would not have gotten this far without your help. Previously the S8 and S9 days were so much easier and people had youtube videos galore that described how to root. The process was easy and everything was unlocked as read write back in the S8 and S9 days.

Yeah I use to use ES on android 6-8 then moved of to solid explorer, very similar ui to ES and also has root explorer but unfortunately it does not work to change permissions on s10 android 10 (bloody samsung/google). So far the only free one I have found is x-plore to be able to do this now. Looks like google is locking down android even more now with android 11
