Read all the Instructions very carefully, as missing even a single steps cause bootloop.
1. Unlocking Bootloader
Allow bootloader unlocking in Developer options → OEM unlocking
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Just when you think the bootloader is unlocked, surprise surprise, it is actually not! Samsung introduced VaultKeeper in the system, meaning the bootloader will reject any unofficial partitions before VaultKeeper explicitly allows it.
Go through the initial setup. Skip through all the steps since data will be wiped again later when we are installing Magisk. Connect the device to internet in the setup!
Enable developer options, and confirm that the OEM unlocking option exists and grayed out!
2. 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
After installing Magisk, you can directly upgrade Magisk within Magisk Manager without an issue.
3. Flashing Magisk:
Download the firmware for SM-M405F
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: 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 tar file to your PC and boot your device to download mode.
Flash magisk_patched.tar as AP in ODIN, together with the BL, CP and HOME_CSC files. Never flash only an AP file, as Odin can shrink your /data file-system if you do.
Important: Uncheck “Auto Reboot” in Options!
Magisk is now successfully flashed! But there are still several steps before you can properly use the device.
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 Power + Volume Up to boot to recovery partition. Just as mentioned in the previous section, since we want to boot into stock recovery, continue pressing the volume up button until you see the stock recovery screen.
In the stock recovery menu, use volume buttons to navigate through menus, and the power button to select the option. Select 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 Power + Volume Up. After seeing the bootloader warning screen, release all buttons so it can boot to the system.
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 internet connection.
You shall see Magisk Manager in your app drawer; if not, manually install the APK you downloaded 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.
Enjoy Root
Successfully rooted Galaxy M40
Thanks for the post. I have successfully rooted Galaxy M40 using magisk. Just one thing to add to the above post-- while copying patched ap from phone to pc use adb otherwise the flashing patched AP fails.

Enable 3CA for Rooted M40
Galaxy M40 uses LTE 2CA but the chipset supports 3CA. Can we enable it for Rooted M40?
Be careful doing this, since the latest Samsung firmware update in August it doesn't work anymore. You can root at first, but then every time you reboot the phone unroots... If you persist and do it again Samsung lock the phone for "security reasons" and you can't even reach the bootloader or recovery screens using the up / down buttons... Meaning you can't go back to stock firmware without taking your phone back to the store or sending for service, but of course you now no longer have warranty.

This method will work for samsung a60 with his own firmware? Its the china better version of m40, i think i'll try this method
Rooted Successfully.
I had to flash twice since it did not boot into the stock recovery first time and messed with root I presume. second time it went perfectly and manually installed magisk manager. later magisk manager did some setups and rebooted my system.
Thanks Dev.
waiting for TWRP

The A60 and the M40 are identical, it's not the "china better version" lol, it's just 90 USD more expensive because Chinese people have more money. It's literally identical down to the microchips inside.

Yeah that was the same issue I was having, I'm using the Indian version of the firmware so I wonder if it just affects Indian models.
I did a lot of research and there's actually not just 5 international models but 7, some with a /DS on the end which appear to use different firmwares, and I wonder if that is the cause of the issue.
Anyway I found a temporary fix. Reset everything back to stock firmware, do the rooting as the guide shows on page 1, then ALWAYS reboot using root, either by installing or upgrading a new Magisk module, or updating your AdAway blacklist, or by using ADB Shell #Su... For some reason when you reboot like this it doesn't unroot the phone and everything stays fine. Also make sure you never ever press the "Okay continue" button that appears when the phone first starts and tells you the bootloader is unlocked, just wait a while and allow it to continue automatically.

Thanks Theseusperse, I will follow that. and can u suggest me easy way to port twrp? I tried carlive image kitchen however when i flashed it not only reboots into stock rom but also shrinked my internal space to 16 GB. To Revert this effect I had to flash stock rom again using Odin ( only odin other tools failed) . Please let me know if there is any safe porting Recovery

There won't be any port of TWRP for a long time, Samsung has to release the source code for the phone first. Based on the Galaxy A series that was released in May this year, they just got their source code last week and the TWRP porting community literally kicked off in the past few days, so we'll probably have to wait some months. I'd estimate November sometime.
I'm excited for when it finally does happen though, I absolutely hate the stock Samsung software and want pure Google, even if it means a GSI rom.
Our phone is actually 100% identical to the Samsung Galaxy A60, so it's possible any TWRP ports made for that device would work, but so far the ones I've tried have all failed and resulted in the same effects you experienced.

Im excited to hear that A60 recovery might work on M40 any ways me either hate to be on stock rom. I got habituated to the root and custom roms. Hope A60 source works for M40 . Please do update me if anything that kind of miracle happens. Thanks in advance Brother

To prevent loosing magisk root after reboot. NEVER REBOOT NORMALLY but Reboot it via Magisk or Fully Power Off then Turn Power On.

No, never ever do this, it will shrink your data partition and there's no way to ever fix it, even with a total system restore or using manufacturer tools.

Too late, I already did that and it shrieked my devices storage to 16Gb first time and 32 gb on second flash. But It got fixed with Odin repartition. Dont worry It is fixable

This is my first post and I'm in need of some help that I can't seem to find anywhere when searching the internet. I'm not a developer nor am I close lol I just have tons of fun learning the development process - it's seriously one of my favorite things to do. Anyways I've messed up royally with my Galaxy Note 5 N910P and I'm stumped on what I should do next! So here's the issue: My Note 5 will not stop boot looping!!! I've flashed stock, almost every version that I'm able to and nothing has worked. The last thing I remember doing before it started this b.s is rooting with CF Auto root. I've always used twrp then flashed Supersu and the dm verity and never had issue! But after flashing the CF Auto root I kept getting kernel is not seandroid enforcing and then the dreadful boot loop issue that has been going on for three days now! Is there something i'm missing? or not doing right? Please message me and let me know, and if this is the wrong place to post about this, I dont mind if my post is taken down just at least help with my question some how! Thank you, XDA is my favorite place - you guys are awesome, I don't trust any other source!!!

First of all you have entered wrong model no here note 5 model no should be SM-N920xx
1)Have you enabled Oem unlocking from developers option before flashing twrp and cf-autoroot using odin? If not then you done a mistake!!
2) Have you tried to flash latest stock firmware using odin with latest usb drivers installed on you pc and proper odin flashing guide?(Flash latest 6.0.1 for your device with latest usb drivers installed on pc and connect phone to main usb port using original usb cable) After flashing stock rom if your facing bootloop then you can try reset through stock recovery (Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
3)If you can boot into twrp recovery normally then flash any custom rom suitable for your device i.e. for sm-n920p..Custom roms are pre-rooted so no need to flash cf-autoroot..Flash custom rom, if you successfully boot up the rom( It's difficult to boot custom rom though if you haven't enabled oem unlocking you will face custom binary is blocked by frp protection),then enable oem unlocking from developers option and try flashing stock rom again
4) Next option for you is download Samsung smart switch for pc, install latest usb drivers on your pc, connect your phone to pc in download mode(Press volume down+power+home button simultaneously),in smartswitch select emergency software recovery, it will ask you imei,model no and serial no which you can find either on box or back panel of your phone,smartswitch will detect latest stock firmware for your device, hit update now,give some time until update complete..Your device will be automatically reboot..If even you face bootlopp, then goto stock recovery(Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
**IF SUGGESTION IN SECOND POST HELPS YOU THEN ITS DONE, AVOID NEXT SUGGESTIONS**
Are you sure you can't install cf auto root again to solve it? IF not...
I did a search and got hits for twrp for N910P. Get it loaded, get it wiped and have another shot at success. Next way to get rid of the persistent rooter gone rogue, load up a factory BL + AP. If that doesn't work download another version and try again.
I've enabled OEM unlocking, flashed latest stock AP...BL.. And so on, factory reset in both factory and TWRP. I have also tried flashing CF Auto root again to see if that would fix it also custom ROMs bootloop except for CM13 and Lineage OS- Which is weird because the ROMs are for the SM N920C model and I'm and Sprint model, So I don't understand that. Weird!! Everything recognizes me as SM N920C except when I am in download mode. Also, having no imei or any back ups make its even harder since my computer completely crashed on me because I am unable to use Samsung smart switch due to the wrong model and null imei. So I'm completely stumped with this issue. Not sure if its a corrupted partition or folders not being in the correct folder locations along with wrong permissions, I've literally stressed everything to my knowledge about this and I'm all out of what issues this could be related to
In this tutorial I will inform you on three different soft bricks, and how to fix them.
You must be able to boot into TWRP and/or Odin/Download mode!
1.) Verification Failed.
Method #1
This method will work with people whom can't reset their device, due to an unmountable /data partition, and those whom experience this error, who can reset but have valuable items, applications, videos, or photos that they don't want to lose. Must be able to boot into Odin/Download mode. (Volume Down+Home+Power)
The solution is actually pretty simple. Boot into Odin/Download mode. This has to be done correctly, not from TWRP recovery. When the prompt for "Volume Up = Continue" and "Volume Down = Cancel (Restart)" press volume down. You should no longer see verification failed, but instead be sitting on the T-Mobile logo. This is normal, and could take 30 seconds to 10 minutes, depending on the amount of data.
This method works all because of Knox. Knox is what Samsung uses to void your warranty. Companies are not allowed to void a warranty when rooting, installing roms, or recovery, unless they have direct evidence. Knox will trigger this when it isn't sure. It will try forcing you to bring it to Samsung, and they can directly find out why it was caused. This happens when it thinks that you cancelled.
Method #2
This one will require you to lose all your data, but is mainly intended for those whom cannot reset their device. Download the stock firmware from the links below. Open Odin (Jodin3 will not work! It is not fully functioning, do not try it.) and boot device into Download/Odin mode. On your computer, you should see 'Added' in the logs. If this does not show up download the Samsung USB Drivers. Select AP and then select the stock firmware. Now flash it. This can also be done through TWRP
For bootloop and frozen Android/Carrier logo just do Method 2. You usually will keep all your data.
FOR 'VERIFICATION FAILED' YOU CANNOT RESTORE FROM A BACKUP!
FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!

Please describe this issue in further detail. Has this been happening out of nowhere, or did you just try flashing something via Odin/Download mode or TWRP.
Also, before flashing did you enable OEM unlock
This also happens when something flashed via Odin/Download mode is incompatible.
Are you still able to boot into the default system partition? If not safe mode?

I should have updated my post, I'm not sure what happened but I flashed stock through Odin and the problem went away, after that I was able to flash twrp and root/install other roms.
It's still weird that the problem happened out of nowhere, not sure what triggered it.
It goes away when u log in to google with the last account that is associated with the phone

Probs OTA. It happened to me my first 3 tries. Ended up factory reseting, and installing fresh via Odin, didn't fix it.
I just turned off auto reboot on Odin, and then pulled my battery on my J7. Booted up straight to Recovery from there.

Sorry I didnt respond.
Looks like you didnt flash encryption breaker. Keep this on your SD Card as its a great way to recover from these errors, and you will need it when you flash ROMS.
Just boot in recovery, flash ashix no verity no encrypt, then reboot into system. You shouldnt have this error.

He's referring to the encryption breaker file ("no-verity-no-encrypt_ashyx.zip") in his first sentence. That is assuming you already had it and should be keeping it on your SD card all the time for flashing ROMs

Was the update sent out to you, or did you download it from SamMobile?
If the update was sent out to you I'm afraid I cannot help, but if you flashed it from SamMobile use an older version like Marshmallow or Lolipop.
EDIT: Make sure you factory reset device and wipe cache after installing from SamMobile.

Just a heads up. There seems to be an issue/bug with the calls dialing out/receiving calls but no window/screen appearing saying that it dailed out or that you received a call (i can't even hang up since the screen isn't there). This happened to me on the google pixel version that you had so i'm attempting to see if it'll happen after just flashing the oreo hybrid on it's own.
Edit: Can confirm it is the google pixel version that is causing this issue. Not sure what's causing it but yeah.

Yeah that was definitely my bad.

I just want to know what has happened to tmobile. They use to right on top off updates. Seems like all they care about us merging with Sprint so the public can get fleeced more by corporate America.
works well
xposed doesnt work needs root
Exynos variants such as International (F), International Dual(Hybrid)-SIM (F/DS),
i am not responsible if anything goes wrong. You are still the one who tryed to flash the files. Even tough this should work as it worked for me and some friends.
Hello XDA
This is my first post (sorry if one already exists)
Today i am going to tell you how to root the Galaxy S9 International on android 9 Pie on stock touchwiz rom.
First of all download all these files;
Prince comsy odin: https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Team win recovery https://forum.xda-developers.com/ga...cross-device-development/twrp-exynos-t3763464
ElementalX Kernel https://elementalx.org/devices/samsung-galaxy-s9/
No verity encrypt: https://androidfilehost.com/?fid=962187416754474353
Magisk 18.0 https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Now for the root
First you need to unlock OEM, you can do this in developer options,
If there is no developer options you need to enable this
you can do this in: Settings>About Phone > software information > click 5 times on build number.
When you unlock OEM everything on your phone gets wiped so make a backup!!
When the wiping is complete, turn off your phone and go to download mode (Vol down + Bixby + Power)
Then connect the phone to your pc and start odin
In odin go to options, and disable f.reset and auto reboot.
Then press the AP button and select the TWRP image you downloaded.
When TWRP is flashed, force reboot your phone (Vol down+ Power) when it is powered off quickly press Vol Up + Bixby + Power to get into recovery
Swipe to allow modifications. And format /data
Then reboot into recovery.
When rebooted mount USB Storage and connect the phone to the PC
Then you can click&Drag the other files (elemental, Magisk, No verity)
When the files are on the phone, go to install and search for the files you just put on the phone.
Install in this order:
Flash No-Verity-Encrypt
Then flash the custom kernel (ElementalX)
And as last flash Magisk.
When you did this, you want to Factory reset, Wipe cache and Dalvik.
Then you can reboot the phone, and install it.
(It is possible that you stay at the boot logo for a long time (Not the galaxy s9 one but the next one) What you need to do then is let it boot for 5 minutes, then force reboot (vol down+Power) and then the phone boots fine)
Again, just to make sure check if OEM is still unlocked (sometimes this get locked again)
Please note that when you do this, you lose secure folder and other functions, also is the knox tripped (0x1)
But the Fingerprint, Irisscanner and samsung account works.
SOMETIMES IT IS NEEDED TO INSTALL THE MAGISK MANAGER MANUALLY, YOU CAN JUST DOWNLOAD THE FILE FROM THE LINK IN THIS POST
Hope this helps.
If you do have any questions, please do the following first;
Note any errors that odin or your phone gives you. I want to help you, but i do need to know what is going wrong.
(Sorry for my bad english)
reserved
So you won't need RMM-state_bypass on pie anymore?!? Seems hard to believe...
And why exactly you need to flash that custom kernel, which benefits does this bring with it?

Click to expand...

If you dont use the custom kernel, you will get RMM error.
Iris scanner wont work, Fingerprint wont work, Samsung account wont work. When you reboot the phone you get a little "Bootloop" at the lockscreen (Screen flashes and is unusable and your pattern isn't saved)
I dont know what else breaks because i cant even get past the lockscreen with stock kernel
(Also you get better performace and battery life)
Hope this helps
work it with s9+?
Sorry for my English...
Yes, but you want to use tgpkernel then otherwise it will not work (problems described abovel
https://www.androidfilehost.com/?w=files&flid=288240
Last samsung phone i rooted was the note 3, and i remember that doing that "tripped" knox 0x1 and this basically voided the warranty. It's the same with S9? is there some non-reversible change that happens to the phone when rooting?

Yes, the knox will still trip (0x1).
In europe, when you can show that the root is not the cause of the problem, they have to fix it under warranty.
Also there are some functions you will lose (forever)
Knox,
Samsung pass,
Samsung Pay,
S-Health(you can fix this one with a build.prop tweak)
Secure folder
If you plan to use one of these (exceptpt s-health) It is better not to root your phone (there are still external app's you can use if you plan to root your phone)
Is there a way to update the stock firmware when you have root? Or do i have to do all over again?
I have this lock screen flashing bootloop issue, what is the fix? I have tried factory restores but get the same results once I set a lock/passcode and reboot. Samsung Account and Bixby also do not work as you mentioned.
You can use TGPkernel then,
Some phones have this issue, some not.
I have seen that 3 friends of mine it worked, and also on 3 not, so this is a very weird issue
What was the fix with them is to install TGPkernel
@co9
The only way i know is to install a custom kernel,
Otherwise you have to download latest stock rom, and flash this using odin.
wich changes your recovery.img and boot.img, aswell as the kernel. so you have to flash this all over again
Thanks for the answer. I already have a custom kernel. So if i always want to have the latest Samsung firmware i have to flash it through odin and do the whole root procedure again?
I tried this method but now everytime I reboot the phone my bluetooth paired device are lost. They also get deleted if I turn ON and OFF the Airplane mode. Anyone else having the same issue ?
Is anyone else experiencing an issue where the password, pin, or pattern set before setting up fingerprint scanning acts like what was entered is incorrect, not allowing you to setup fingerprint scanning?
I've tried setting up fingerprint scanning on initial setup as well as skipping and trying after the phone has been setup but had no luck. What ever I set initially will not work when I'm prompted later on when trying to setup fingerprint scanning or tying to access other secure features. The phone just prompts to try again acting like I entered in the wrong password, pin, or pattern. I've even tested by setting up a REALLY simple password with no luck.
I have confirmed in the settings that Elemental is installed.
Edit: I did find this thread https://forum.xda-developers.com/galaxy-s9/help/root-galaxy-s9-exynos-9-0-android-pie-t3884267. I tried the no-verity-opt-encrypt-6.0.zip that was suggested in some posts but had no success. I've also tried the TGPKernel but had not change in the issue. I am able to setup fingerprint scanning on fresh firmware install but after installing TWRP and everything else the above issue happens.

Don't root this phone without flashing a custom kernel or a modified stock kernel. It will drain battery and reduce the performance or even crash the system.
Look in the TWRP thread there it is explained why you shouldn't do it.

My personal experience is i have rooted using this method and have had no problems
Hi all,
I tried to flash twrp but never succed.
S9+ last firmware from samsun android 9 pie (update from smart switch)
Then option developper activated, no oem unlock menu found,
boot into download mode and there is written oem unlock desactivated so ok
with odin try to flash (ap, reboot freset unchecked)
then fails and message in red on the phone :
"only official released binaries are allowed to be flashed recovery"
History :
I was in galaxy project oreo, i wanted to upgrade with pie, but reboot cycle
so rescue with odin and original oreo firmware, then update to pie
thanks for help
regards
To get the oem unluck button visible.
After fresh install, go to time/date in settings, choose manual and set the date 1 mount prior (march will be februar)
Than go to software update, choose manual en click on dowload updates manually.
Restart your phone and the oem unlock button in developer options will be there
Cheers
thank's for answering,
Update done, reboot ok but still not oem options in developpers section
Hello guys, decide to mount this tutorial because I still see a lot of people with doubts, yes we already have how to root our device
I did it on mine and it worked, do it at your own risk, neither I nor anyone else on the forum is responsible for any loss
A tutorials too complex for some users, teaching you how to create your own Magisk modified Img boot, but I like simplicity, so if you don't want to break your head too much, here's a tip, use a successfully modified img boot , what you need is to install the rom stock that was used to create the modified boot first.
let's go to the tutorial, warning that the files posted here are not my own, and if it doesn't work, check if you're not commenting on any flaws, don't try to memorize the tutorial, follow it step by step. come on!:dedos cruzados:
1 - first follow these steps to unlock the bootloader:
This is a basic step to root device. Go to settings - about phone - Software Information - tap multiple times on "Build number" - This will open developer option.
Now in settings at the end, you will have new option "Developer options" - look for OEM unlocking - Enable it.
(PS : If you don't see this option then you may need to wait up to 7 days or more to appear or may be on some operator you will get it never. Without this option you can not root your device, sorry!)
Once you have enable OEM unlock option, switch off your device and reboot to download mode.
To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable
When device start to download mode,long press volume up to unlock the bootloader. This will wipe your data and automatically reboot
Now let finish setup and again enable developer options (as said above), and confirm that the OEM unlocking option exists and grayed out!
If it is not then you can not root device!
Once you see this option and greyed out, you are ready to flash custom binary and root your device.
Now let's go to the next step, reinstall an outdated system, I did it on mine and it worked, do it at your own risk, neither I nor anyone else on the forum is responsible for any loss
2 - installing the stock ROM that we will use:
download this rom: https://samfrew.com/ru/download/Gal..._Wi-Fi-__/rue3/KOO/T290KSU3BUE1/T290KOO3BUE2/
OBS: a little detail about this firmware, it is made in arm32, which apparently makes it "lighter", but also has a more acidic use of RAM memory. This was the last software I installed on tab A, and I can say that the use has become better with it, but if you want to stay in the stock rom, even custom gsi didn't get such a good performance. It's worth testing, but be aware of the risks, I'm not responsible for errors.
Updating: use a modified version of Odin, to do the installations, be careful with downgrades, I managed, I was in the most current version of March, and I managed anyway using this modified Odin, but do it at your own risk, download the most current version here:
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
And install via Odin, if you need more details just a Google, there are already millions of tutorials for that lol
when you get here you should already be aware that you have lost all your data, but it is necessary that the OEM option is enabled in the options, so in the CSC session use Home CSC, so that you leave the data saved, and do not lose the initial settings : )
once with successful installation, we will now install the file modified by magisk
3 - magisk Installation:
Intall TWRP: https://forum.xda-developers.com/t/...-2-for-2019-galaxy-tab-a-8-0-sm-t290.4185235/
just follow our friend's tutorial, with a little observation, after starting the process in odin, be sure to hold the volume up button + turn on, to be redirected to the TWRP.
follow the standard steps to install magisk, if it doesn't work, you will have to manually modify the system boot.img along with magisk maneger.
if case of problem:
The process of entering recovery on the SM-T290 using buttons is really finicky, unlike the 10.1" version. My best result has been with holding Power + Vol Up on startup, quickly switching to hit Power to dismiss the bootloader unlock warning page, and then immediately holding Power + Vol Up again for 6 seconds. (Holding longer will cause a hard reset.)
If you miss on the first attempt and haven't installed Multidisabler, it will revert your custom recovery to the stock OEM recovery.
I haven't had the tablet in my hands for a few months, so unfortunately I can't help more than that, as I said this was the last system I used, just because GSI are not very functional and are not always light, sometimes they crash more and it has more annoying bugs to fix that discourage daily use. my tip is, stay in stock Koo, excuses for those who can't, the most I can do now is guide them.
As a gift for you, I will teach you how to use Xposed :3
remembering, I did several tests that several times I faced bootlooops but in the end it worked for me, so notice, do it at your own risk.
5 - How to install end use EDexposed with Magisk
these versions were the ones that worked without problems in this rom
Install Riru - (Riru core) V21.0
Install Riru - Edxposed v 0.4.6.1(4510) YAHFA
Reboot, after reboot, install Edxposed Manager
and you can be happy

Has anyone attempted this yet?
I am attempting to apply this root and I have run into a minor issue.
The AP Patched file from magisk isn't compressed correctly. Maybe I don't understand, but using 7zip, i can see that all the compressed files inside the AP file are LZ4's, but after patching with magisk, some become .IMG and odin errors our whenever I hit modem.Bin.
Any Ideas?

Hi friend, sorry but there are more current ways of routing, even already working on a TWRP, but now you can do the following, try using the same Firmware in the same version of the bootloader, otherwise there will always be an error, the file compressed this modified to work with Odin, I tested it myself on my T290, but I cannot guarantee its effectiveness if I try to use it in another version, I do not recommend doing this even.
I had trouble unlocking the bootloader until I did this:
After enabling OEM unlocking and turning the device off, plug in the USB cable. Hold both Vol + and Vol - at the same time, then unplug and replug the USB cable. The bootloader unlock screen should come up.
I posted this on twrp thread, but seems no one wants to answer , thought give it a try here?
Anyone know of a fix for the blank screen?
Not sure why they would lock down this tablet but not others?
Whats the point of unblocking the bootloader if you can not do custom roms , root etc?
My firmware is on T290XXU3BUC1
I can successfully installed twrp via Odin.
I reboot, instantly blank screen. I have rebooted into twrp with blank screen.
I was able to install the nexus rom, with adb twrp command line and works but all is blank screen.
I go back to stock and the display is back.
I have tried another twrp on this forum but that gives me security error.
I have also tried to patch ap tar with Magiskt but that flashes but when restart get security error.
Twrp is the only thing that works but complete blank screen with back light.
Tab is unlocked bootloader and oem unlocking on.
does this work if you're on a11?

what are you specifically asking? the TWRP here is very functional, but custom roms are not very stable for this tablet, some GSI behave well, but it's still better to stock debloated

Hi, maybe you can help me.
i rooted my SM-T290 MXO with Android 10 but the system always asked me about a new patch update (May 1 Update) and i dont know how to apply updates so i downladed the firmware update via ODIN, long story short after applying the firmware and updating trough Smart Switch (because now my tablet say that the SO has been modified and now i can´t update trought OTA) and now i have Android 11 with One 3.1 so my questions are:
Can install TWRP like before in his version of Android?
In case i need to downgrade to Android 9, do i need to be the exact carrier (XAR = United States) in the file you put or should i use my carrier (MXO = Mexico) and is the same result?
I hope anyone can help me because i dont know much about rooting and is the second time im dealing with rooting a Samsung Device (My first attempt was a Galaxy 4 and was frustrating that KNOX detected my bad root)
Thanks in Advance.

yes, you can go back to previous versions, but it gets harder when you upgrade bootloader version.
In order not to crash the downgrade, you need to look for the latest Android version you want, from your region you are in now.
An example:
I'm on the latest version ZTO - Brazil - Android 11
to get back to Android 10 I need to download the latest ZTO version with Android 9, of course you can try between different regions, but it will be a little more complicated.
Hello
I was asking, how do i root this thing lol, it has been a nightmare
I can not root with custom magisk patched rom, as get boot error, and i can install Twrp, which works, but i just get a blank screen.
Was wondering if there was a work around?

You mentioned it's on Android 11, didn't you?!
well, I don't have Tab A with me anymore, but the suggestion I give you is to try to go back to Android 10, then install TWRP, and then try to install magisk, I can give you the last firmware I installed,
currently he is with my brother.
The firmware is Koreano, as I said, it is 32bits, and super functional.
Samsung SM-T290/T295 Galaxy Tab A 8.0 (2019) - Прошивки - 4PDA
Samsung SM-T290/T295 Galaxy Tab A 8.0 (2019) - Прошивки
4pda.to
take a look here, search for the firmware I told you about, very good by the way
Hey
I am on T290XXU3BUC1 and i do not understand the language on the link you post
I tried your tutorial , but i am getting
sw rev check fail [aboot] Fused 3 > binary 3
hello, about that, but lately I don't have much time, but I'll update it today if I can, you probably got this error because this firmware is old.on 4pda there is a newer version with root, remembering that currently you can root through twrp, I'm going to port my last attempts here, but I notice that I don't have the tablet in my hands. use translation tools, the site is in Russian
I updated the guide as I could, any doubts I'm still here, but I can only guide, it's no longer possible to test.
Thanks for the update. The only problem is, is that i have the newer tab and when I flash TWRP, i get a blank screen
I need a way to patch the firmware without failing, as i do not think anyone is trying to fix the blank screen bug with TWRP, unless they are on 4pad.to , but no idea due to the language barrier hehe.

have you tried to put the firmware I mentioned? this tutorial probably won't work on android 11 one ui 3.1, i say this because the TWRP is a bit old, so as long as it's on the updated firmware it's really hard to do anything.
if you don't want the specific KOO Firmware, you can get the latest firmware version for your region which is on android 10.
