My apologies if this post is a dup, but I'm havin a hell of a time trying to find the proper steps to root the WiFi only XOOM i have hangin out next to me.
I am seeing a ton of posts about rooting the XOOM, with a good bit of them telling me different informationDated 27 April 2011)
http://forum.xda-developers.com/showthread.php?t=1010568&highlight=rooting+wifi&page=17 tells me to download the WiFi only image (Tiamat 1.3...), but then later tells me to download the Tiamat 1.4 images. [scribbi, my apologies for using your post as the example. But your post got me second guessing myself a little bit...(mostly cus I'm paranoid)]
I'm sure I am just second guessing myself over nothing, but just to be sure...
Is there a GOLDEN set of steps (or sticky), as of 27 APRIL 2011, that can give us (concerned rooters) the proper steps for rooting the WiFi only XOOM such that we can follow without minimal concern for the well-being of our tabs?
(I'm an embedded SW engineer, so I understand the repercussions of what I'm doing, which is why I'm to double checking the procedures before I attempt something that may brick my hardware)
Thanks for your time and mad props to everyone that was part of the effort to root this device. I wish I could code as well that they can.
I still do it the old fashioned way. I'm already unlocked so I just flash the boot image. With a clean system partition, you need to push a few drivers (.ko files) on plus "su" and the Superuser.apk. Superuser and su work together. And finally you need to create a new folder so that your real sdcard can be mounted. I think they changed the name from "sdcard2" to something new in 1.4.0.
Not exactly step by step but you can see which instructions that mirrors most.
New instructions involve CWM which I have not installed yet. I like to know what's done step by step as I have a Canadian system.img. I don't want that flashed over.
you could use the "one click" method found in the dev section. its really like a one click at a time, but goes slow so you can read and see what's going on. if your not comfy with adb I would suggest this method. then update the kernel with the kernel manager app.

I don't trust the "one click" methods. Me, I need to know how every part works together and what every step does. I'm more comfortable with using adb and fastboot manually than I am with someone's idea of user friendly. I'm also the kind of guy that would fix his own car rather than have a mechanic fix it for free.
I should take a look at it. The way you describe it, it almost sounds like a batch file.
Also, when I understand what's going on, I can apply the steps in different situations. For example, most of the instructions here are for a PC but I can do exactly the same things with my Mac Mini when my PC isn't convenient.
OK, let me propose one of the root method which is not required to flash any boot image but is required to flash ClockworkMod Recovery and to use the recovery for rooting.
Such method (i.e. using custom recovery) may work not only on WiFi US model (which I have), but also on other models (Verizon, WiFi Europe etc). But I tested it on WiFi US.
So the step by step are:
1. Install ClockworkMod Recovery v3.0.2.5 as described here:
http://forum.xda-developers.com/showthread.php?t=1038870
This actualy means that you need to unclock bootloader and flash ClockworkMod Recovery.
2. Download attached Root_Xoom.zip file and put it on SD card
3. Insert SD card into Xoom
4. Boot Xoom in the recovery mode
5. In ClockworkMod Recovery menu choose "install zip from sdcard" and "choose zip from sdcard" and install Root_Xoom.zip
6. Reboot Xoom
Hope you will have Root after that.
ok so since I'm not currently rooted it looks like this should work for me. Gonna give it a shot in a little white once I get me some courage juice...

Other than rooting what else does this particular file do? Ovrclock, usb hosting, sd access??
Thanks

This is for rooting only (as OP requested). It is just to push su binary and superuser.apk into system partition. Nothing else.
after that, get kernel manager and install 1.3.2 for oc, sdcard etc.... 1.4.0 isn't stable is it?
Yes, if you need oc, sdcard etc..., you can flash the kernel you like. It can be done after or before kernel flashing.
Do you have to have an SD card to CWM/root your Xoom?
Yes, you need SD card. CWM installs file from SD card to make root
As the title states, I need help with understanding the basic steps on rooting the ASUS TF300.
I am not a programmer, I do not know the lingo or terms, and searching on the site has yielded very confusing results.
Basic steps?
1. Unlock boot loader - Why? What does this do?
2. TWRP? I have no clue, but I see references all over the place
3. Custom Recovery - What does this do? Do I need it?
4. Kernel - What is this?
5. ROM - What is this?
6. Install Super SU or SuperUser (what's the difference?, what does this do?
7. Install a root check app (to check if rooted I presume)
8. Install some form of file explorer (I have Fx File Explorer) and backup/control app (I have Titanium backup)- both paid forms
9. De-bloat with caution!
Where does the OEM firmware/software fit in this scheme? Does it exist as a backup or is it over-written? Do I have a choice?
As you can guess I'm lost. Reading threads after searching for "root TF300" or even the guides or the very good index, I have more questions than answers. How does one know what to do if the acronyms used are cryptic? (example TWRP~ what does this even stand for?)
I believe that not all steps are required, but I also believe the order I do things is important, and I'm concerned about bricking my TF300 by doing something wrong. I also don't want to assume that this is the same for every device or phones. (what steps work for a phone may not be the best for a tablet)
All I want to do is root and remove bloat. After I get this, I may consider upgrading the OS (kernel? Rom?) to something better.
Any links would be greatly appreciated. Please just bear in mind I'm so noob to this I don't know a ROM from a Kernel yet. (When I search, all answers are overly complicated developer definitions.)
Thank you!
Here is a "simple Step by Step" with notes in red as to how my mind tries to grasp this:
1. Upgrade your tablet to the desired firmware: 4.1 or 4.2 I assume they mean any OTA upgrade~ my tablet is current with JB 4.2.1 and I do not believe ASUS will plan on upgrading this anytime soon)
2. Be sure the correct drivers for your tablet are installed!! Installed where? on my PC? How do I know what are the correct drivers? Where can I get them?
3. Download the updated rooting toolkit: Updated Motochopper rooting toolkit -OK, I can do this!
4. Download TWRP for your firmware version:
- 4.1: TWRP 2.5.0.0 for Jellyeban 4.1
- 4.2: TWRP 2.5.0.0 for Jellybean 4.2 -This makes sense to me, as I am jellybean 4.2.1
5. Rename the downloaded TWRP blob file to twrp.blob and copy it to the root of your sdcard -what is a blob file? Is there a size requirement for the SD card? Does the SD have to be blank?
5. Extract the rooting toolkit to a place you like. -I assume the above mentioned motochopper? Does this answer my question above about the SD card?
== Part 2 - Rooting ==
1. Open up the folder where you placed the rooting toolkit. - with what program? A simple file explorer I assume?
2. Open the run file and follow the instructions -I hope there aren't any cryptic/over my head choices to make!
After installation the tablet should reboot and you should be rooted. -Does this install all the SuperSu stuff or is this it? What about customer recovery? Can I go back? what are the limitations of doing it this way assuming it works....
And this is just PART of the process!
I'll answer in logical order:

5. ROM - What is this?

That's the Operating System that's running on your tablet, i.e. what is called Lollipop or KitKat, or even further what makes the difference between Android and iOS.
Your ROM may come with some preinstalled apps, but with some ROMs they are separate (i.e. the Google apps).

2. TWRP? I have no clue, but I see references all over the place
3. Custom Recovery - What does this do? Do I need it?
Click to expand...
Click to collapse
On your ASUS tablet you can, by default, only install ASUS supplied ROMs (i.e. updates).
In order to install a new ROM you need to unlock your device. You do that by unlocking the boot loader. Once you have unlocked the boot loader, you can install a custom recovery, such as TWRP (there are many custom recoveries, but for your device TWRP is recommended).
Once you have a custom recovery, installing a new ROM, or rooting your device, becomes a lot easier. No need to type in commands, but you can now use touch.
broderp said:
4. Kernel - What is this?
Click to expand...
Click to collapse
Your kernel is the most important part of your ROM. It's the software between apps and your actual hardware, the lowest level actually. The kernel determines if you can talk to certain pieces of hardware or not. If the kernel does not support certain hardware, that's it, you can't use it.
When your tablet boots up, the first thing it loads its the kernel, the kernel loads all other programs. Another responsibility of the kernel is to allow you to run multiple programs at once.

6. Install Super SU or SuperUser (what's the difference?, what does this do?

They allow you to execute programs with root privileges (i.e. no limit to privileges, can do anything), but also give you some protection so malicious programs cannot become root: you have to give explicit permissions for every app.

Firmware often is part of the hardware: it gets written to special memory, and "sticks", i.e. when you reboot it stays there. If you get a T300 you should let ASUS run all the updates as it installs new firmware. Some firmware gets written when your device boots, meaning the special program, the kernel, starts, and at some point writes updated firmware to hardware.
So firmware is software that makes hardware a bit more flexible: else everything is hard-wired, if there's a problem you can't fix it, but with software you sometimes can fix a hardware issue.
Hope this helps!
First, to unlock the bootloader, you need to go the asus site and register your tablet. Then you can download the unlock app from the asus site as well. Next, move the unlock app from where ever it downloaded on your pc to your tablet. You can put it on the tablet RAM or on an SD card, it doesn't matter. On your tablet, go into the settings menu. under security(I think it is there) and enable 'unknown sources' for app installation. I haven't had the stock ROM for so long, I can't recall where that option is. Run the unlock app. It may take a couple times to unlock the tablet. WARNING! this will void your warrenty! So if your tablet is relatively new, think hard about this. Once your tablet is unlocked, then you can worry about TWRP and ROMS
TWRP is a custom recovery. It is officially Team Win Recovery Project, hence TWRP. It is a program that will allow you to back up your tablet before you make changes(very important in case you screw something up) and a host of other things including flashing custom ROMs. If you go into the LP 5.1 for the TF300 thread in the development area, it will have all the links for stuff like the current TWRP, Gapps packages and the newest LP ROM. It is great for our tablets and really wakes it up. Oh yeah, the TWRP site will have instructions for flashing TWRP on your newly unlocked tablet as well.
All this seems very intimidating for noobs, I was one about 4 months ago. I now feel sort of not-noobish. To install TWRP you will need either Fastboot or ADB on your computer. Google Fastboot or ADB and you should find plenty of answers. There are also 'lite' versions of Fastboot out there too. If you are on Windows 8 or 8.1 you will need one of those. Windows doesn't like fastboot or ADB for some reason

I was frustrated by the huawei encryption and decided to get rid of it once and for all.
At first I faced many bootloops but i finally figured out what was going on. Formatting user data through TWRP is not enough because after booting the device, encryption is still there. This happens because the kernel encrypts the device when booting up. Simply modifying the boot.img file to remove file encryption also doesn't work because you still boot into an already encrypted stock user data. So the answer was pretty obvious by now.
The trick is to format data using TWRP AND THEN boot to bootloader to flash a modified boot without encryption. So let's get to it.
How to create a modified boot.img without file encryption/dm-verity
1. Find and download your current firmware from Huawei Firmware Finder Dtabase (Team MT), or from a source that you trust. (Using a firmware with different cust version or a different update will most likely not work).
2. Download Huawei Update Extractor and use it to extract the stock boot.img file from UPDATE.APP
3. Download ASSAYYED_KITCHEN.
4. Place your stock boot.img file in the "WORK" folder of ASSAYYED_KITCHEN.
5. Launch ASSAYYED and select the 12th option (KERNEL/RECOVERY MENU) and then the 1st one (Unpacking Kernel).
6. The ASSAYYED options don't work for me so i did it manually. Go to your work folder and open the folder boot_unpacked\ramdisk.
7. You will see a file named "fstab.qcom", open it using WordPad.
8. Find the line:
Code:
/dev/block/bootdevice/by-name/userdata /data f2fs nosuid,nodev,noatime,discard,inline_data,inline_xattr wait,check,fileencryption
and delete ",fileencryption".It should now look like that:
Code:
/dev/block/bootdevice/by-name/userdata /data f2fs nosuid,nodev,noatime,discard,inline_data,inline_xattr wait,check
9. (This step is optional,follow it only if you also want dm-verity removed) Use the same method to remove dm-verity.
Code:
/dev/block/bootdevice/by-name/system /system ext4 ro,barrier=1 wait, verify
/dev/block/bootdevice/by-name/vendor /vendor ext4 ro,barrier=1 wait, verify
/dev/block/bootdevice/by-name/product /product ext4 ro,barrier=1 wait, verify
(Just delete the ",verify" part.)
10. Save the file.
11. Launch ASSAYYED and select the 12th option (KERNEL/RECOVERY MENU) and then the 2nd one (Packing Kernel).
12. Follow the instructions below to properly flash your modified boot.img and get rid of encryption.
Removing file encryption/dm-verity from the device
1. Unlock your device.
2. Flash this TWRP on AGS-W09 or the appropriate custom recovery for your device.
3. Boot to TWRP and FORMAT user data (note that it is very important to format data and not just wipe it). •WARNING• this will delete all your data!
4. Go back to the reboot menu of TWRP and select reboot booloader (it's important to not allow your device to boot into system yet).
5. Using fastboot, flash your modified boot.img that you created earlier.
6. Reboot your device (you might get a bootloop on the first boot but force rebooting your device again by holding the power button will fix that).
7. After booting up, your device should not be encrypted anymore.
8. You can now use the root method that you like to root your device and internal storage should be visible on TWRP. TWRP backup should also work normally.
How to fix Magisk modules not showing up on Magisk Manager (! /data/adb/magisk_merge.img mount failed error)
I am not going to get into the technical staff you can find more info here
Edit: As of Magisk 19.0, the following method becomes obsolete. Magisk modules should now work as expected without issues. This method now concerns those who want to stick to an older version of Magisk
1. Download f2fsfix-2018.9.2.zip provided by VR25 on the thread above.
2. Download all the magisk modules that you need to flash and place them on your device.
3. Download the latest Magisk uninstaller along with the latest installer.
4. Boot to TWRP and flash Magisk uninstaller. (If you don't have Magisk already installed, skip this step)
5. Wipe Davlik Cache.
6. Install the latest Magisk.
7. Wipe Davlik Cache.
8. Flash the "f2fsfix-2018.9.2.zip" immediately followed by your modules.
9. Reboot (it should take more than usual).
10. Open Magisk Manager and check your Modules. Hopefully they'll show as installed and function correctly.
Note: This method should also work on similar devices. Just make sure you know how to recover your device in case something goes wrong.
I can confirm this worked for me. I was able to run a full nandroid, but haven't tried to restore. Wasn't running any magisk modules, so haven't tried that part of the guide. Flashed Xposed in TRWP and installed greenify, etc Seems to be working. So far no errors. Be warned, this is like a restore. You'll be starting from scratch again.
Also thanks for the boot image trick Thanostsak. I couldn't find stock fimware for my version (AGS-L03) anywhere. He suggested to use the Magisk's boot image backup. Worked like a charm. Still looking for AGS-L03 stock if anyone has one, knows where to get one please post!

Glad it worked for you. Yes this is the downside. The device already comes with an encrypted userdata, so it needs to be formatted. So anything you do before that becomes obsolete. That's why this procedure is much more convenient when it happens after the unlock,when the userdata is wiped by the stock recovery to get a stock condition.

I just followed your detailed guide to my tablet and finished all the processes perfectly.
Working..Twrp, Magisk, removed encryption & verify from boot.img and from Data successfully.
A big THANKS for your guide, links and trick all in one post!!!!.
Thanks for the info.
I am new to android (but have jailbroken iOS for years).
I have received a Huawei MediaPad T3 AGS-W09 (AGS-W09C100B278) today.
I have managed to unlock and install TWRP 3.2.1 but also want to install SuperSU, but of course the filesystem is encrypted, which brings me here.
I have searched all over for Huawei MediaPad T3 AGS-W09 (AGS-W09C100B278) firmware which contains boot.img but cannot find it. Even the rom on the AGS-W09 thread on this forum doesnt contain the .img file. Am I missing something ?
Any help is appreciated.
Thanks again

I strongly suggest using Magisk to root your device instead of SuperSU. The good thing about Magisk is that everything happens systemlessly, so it doesn't matter if the kernel is encrypted in order of it to work. If you still want to use SuperSU though, my guide should provide all the info you need.
To answer your question you can find two OTA firmware updates for your device here. If that doesn't work (if the OTA updates don't include the boot.img file ) i will let you know how to use magisk to get a copy of your current boot.img

I have been looking down the Magisk avenue too.
My plan is, decrypt is then root it.
I did download those firmware files earlier but as you say, no .img files.
I have tried to follow a guide on youtube from rootjunky but got as far as running the info gathering piece to gather mount points, but it fell over. Don;t know if thats because I was using adb sideloading via TWRP .. ?
I attempted to run the commands from the batch file direct but no joy.
It would be really appreciated if you could point me to a guide to extract the img. It's my day 1 of this device and Android (already voided warranty from Amazon within 1 hour ha) but as I say, I have experience in most of what is needed from my iOS jailbreaking and bringing phones back from bootloops and the brink of bricks.
When you mention rooting with Magisk .. Can that be achieved in the state my device is in now, which is TWRP'd but encrypted ?
I also notice the "Ultimate Backup Tool, No Root Required" thread (cant put URL's yet as I'm a n00b member). Could that export my boot.img ?
I am done for today. I am working from home and it the device got delivered at 9:30 ish. I was hacking around with it all day and did about 20 min work. I'm fried now :-O

I get what you are saying. Going from iOS to android is a big step. Since the firmware files don't contain the boot.img and having in mind that you want to decrypt, getting a boot.img file is a must.
There are ways to get the boot.img without root but the ones i tried don't work. But there is an easy way that i know of that requires installing Magisk. When you flash Magisk from TWRP it roots your device. However, apart from rooting it also creates a backup of your boot.img in case something goes wrong.
Decrypting requires formatting your device, so Magisk will be removed too. So its only purpose for now is to provide you with a boot.img file.
Here is what you need to do
1. Download the latest magisk installer from the magisk threat
2. Save the file in your SD card (internal storage is encrypted)
3. Flash the Magisk installer from TWRP
4. Boot your device and navigate to /data
5. There should be a stock boot_xxx.img.gs file in there. Copy it to your storage, move it to a computer and extract it. You should get a boot.img file that you could use to decrypt.
6. Follow my guide to decrypt the boot.img and then flash it from bootloader
7. Since your device is now formatted from the decryption, you can choose the root method that you like.

Makes total sense. I just installed Magisk now from SD, thing is, the only spare SD I had was 128MB !! So I dont know if the .img was saved correctly. I will look into it tomorrow. My other large SD is corrupted but I have a 32GB one in the dashcam I will use tomorrow.
That leads me to a question. Is the auto created .img saved on the card or the internal storage ? I am assuming its card but I could not see it.
Will look more tomorrow.
Thanks

It is actually on the internal storage. Now that you are rooted you can use a root file explorer to get it. (128mb should be enough for this task)

Great! If you need anything feel free to ask.
Well... I followed your steps to remove force encryption and install Magisk, everything seems to be perfect. The Magisk and modules are funtional. However after reboot all modules are dispeared, but magisk is still recognized by magisk manager. I don't know where is the problem...

magisk version: 17.2 (At first I used the latest 18.0 version, but after this problem appeared, I noticed that f2sffix-20181009 only support magisk version 17.2 or older, so I retry your method with magisk 17.2, but the problem remains.)

Well... I followed your steps to remove force encryption and install Magisk, everything seems to be perfect. The Magisk and modules are funtional. However after reboot all modules are dispeared, but magisk is still recognized by magisk manager. I don't know where is the problem...

You should use the latest version of f2sffix (10.9) and then follow the procedure again. After your first boot follow VR25's recommendation and you should be good to go.
VR25 said:
Those getting everything broken after a second reboot, try the following workaround...
After the first reboot (right after installing), remove </sbin/.core/img/f2fs*bla*bla/service.sh>, </data/adb/magisk_merge.img> and </cache/magisk_merge_.img>.
Note that after doing this, you'll only be able to install modules and update Magisk from TWRP.

what if there is no fstab.qcom in kernel but stored in vendor/etc partition?
i've already edited the fstab, but still my system partition become ro (read only) when i made a change in system. all file manager error even previously has root.
please take a look at attachment . thanks in advance

I believe that what you are missing is after changing forceencrypt=footer into encryptable=footer you should also do a full data format through TWRP.

encryption is not a problem. since the first place already done with that data partition.
my problem is system partition, every time i made a change to system (for example deleting chrome.apk), something triggered that makes my system weird (magisk forceclose, all file manager become malfunction because system become read only). something lock my system partition if system change.
i thought change fstab.qcom <mnt_flags and options> ro,errors=panic to >> errors=continue (deleting ro/read only) will change my system behaviour, but it's not
Hi,
Finally I had time to finish my work on Xcover 4. I couldn't disable ForceEncryption by any flashable tool so I prepared 2 version of firmware (Oreo and Pie), both prerooted (Magisk) and free from Force Encryption. Everything except boot.img left untouched, both ROMs are BTU so no brand.
Just flash it with Odin 3.13.3. I recommend to flash CSC_BTU instead of HOME_CSC_BTU. HOME BTU should work as well but then probably You gonna have to format data with TWRP. CSC_BTU is already tested and there are no problems with Encryption.
After flashing just install Lastest Magisk Manager. SafetyNet Passed.

If You need TWRP (not necessary to flash this ROMs) flash this version:
TWRP: TWRP-3.1.1_SM-G390F_by_nemo-nemo
Code:
https://mega.nz/#!DIo1SSBT!w4dPPAF3BEcfQmsy7mANO33Lb5Gj4jzDkrrPfbH56uo
Working on both versions, Oreo and Pie. I didn't test backup and recovery options but flashing is working on both. ADB and MTP are not working.
To remove Security Log Agent notifications use SecurityLogAgent Disable. It will disable this annoying app completely.
Hello!
Can you explain because i would like only to root my phone in oreo 8.1 without losing apps and data. Is it possible with your method?
thank you for your answer.
Would anyone happen to know if I can use TWRP for SM-G390F's on SM-G390W's? (the only differences I know of between them are the supported LTE frequencies)
You can try to flash it, just backup your data and if something goes wrong just flash it with back with stock firmware.
Updated main thread
Hi mates
very interesting matter. Will like to make it from a ubuntu 18.04 system? Did someone had tried it ?
Yea, it's a normal ROM so you can flash it with Heimdal.

thank you C for this fast answer .
Here is the second point :
IS this rom free from google , I mean enough
And the third
any visible amelioration from the XCOV 2 Model in battery standing . I do not care about photos for my purpose .
Only memory, increased by SD, and lasting time
It's completely stock rom without any modifications except integrated Magisk and disabled force encryption. Rest is untouched.
I don't understand what file I should use to flash with Odin.. in the link you posted sends to a download of a zip file of almost 2gb in which there are many files, so from those files which one should I set in Odin?
Flash it like any other stock ROM:
BL file in BL
AP file in AP
CP file in CP
CSC_BTU file in CSC
Everything works great:]
Thanks man.
Hi Chamelleon and thanks for all the effort you've made already!
I successfully flashed the Pie variant of the two ROMs and got it to work. However, turned out that in an app that I'm developing, for some reason, when my device is equipped with G390FXXU4CSF9_BTU_G390FBTU4CSFA, the app doesn't behave in the same way as when G390FXXU4CSF9_ G390FXEO4CSFA has been installed. That's why I would like to be able to root the XEO-version of the firmware. Moreover, there will be many other non-rooted devices equipped with the XEO-version using the app in the near future.
Having flashed my device with G390FXXU4CSF9_ G390FXEO4CSFA, I tried installing the version of TWRP you have provided but I can't figure out how to install Magisk from there. By default, TWRP can't find the Magisk zip-file that I push onto the device. I tried formatting data, as per this post. The post lead me to believe that the files could be found after formatting but even though there were now plenty of TWRP-related folders, I couldn't find the zip. And as ADB and MTP don't seem to work in recovery mode, I'm unable to get the zip file on board after formatting. Booting to system doesn't work either after allowing modifications for TWRP, which might be due to dm-verity preventing boot, but franky I don't understand much of that topic.
You mentioned that you couldn't disable Force Encryption with any flashable tool. Is that the reason why TWRP (or any other tool) couldn't reach the zip file for Magisk?
This is the first time I've attempted rooting a phone so my knowledge regarding the topic is pretty basic.
So I suppose preparing a prerooted and Force Encryption free version of the firmware might be a possibility? I have no idea how to patch a ROM though. Any advice on how to proceed?
Hi, I had no time to play with this during Christmas. If you send me your boot.img I can modify it for you. If You just flash magisk with TWRP it will root your phone but after first reboot whole data partition will be encrypted again and you wont be able to flash anything with twrp or modify data partition without full wipe. For some unknown reason this and probably more Samsung models have different structure of files responsible for encryption and because of this none of pre-made patches are working. Only manual kernel modification can safe from encryption, at least for now.
I'm not a developer so I don't know how to prepare patch for this to allow anyone to flash it, I just found few lines of code in kernel You need to modify to disable encryption.

How to flash firmware on linux?
I know that i have to use heimdall but how to load these files into the program because filenames say basically nothing to me.
Thanks in advance.
Also does it delete user data?

1. Flash clean ROM, same as boot you send me)
2. Enable OEM Unlock in Developer settings
3. Flash patched boot with Odin as AP/PDA.
4. Install Magisk Manager app
5. Install TWRP and format data partition, option where you need to type "YES"
6. Reboot system and then back to TWRP. If you can mount data and there are no errors it's done.

Sorry but I never had a chance to use Heimdall. You can't dirty flash this because when your phone is encrypted and you can't replace kernel corrupting data.
But do I lose my data(Apps settings etc.)?
I'm OK with setting everything up back ,but it would be cool if it kept data.
(I'm going to use other computer that has windows on it btw, and I'm going to flash it with odin)
If your data partition is encrypted you gonna corrupt it by changing kernel. It means You wont be able to access, so yes, you will loose it.
What you mean by encryption some option in the Android or what?
If that's what you mean I haven't set up anything like this
I own some old samsung Galaxy models like J7 Prime and had tried good Custom ROMs on them but up recent I purchased this Samsung Galaxy M21 2021 Edition (SM-M215G/DS) a few days ago thinking that it's going to be same as Galaxy M21 2019 (SM-M215F) model, to my horor its bootloader & recovery seems to work differently from J7 prime (with bar codes in download mode) . So it's a differrent model. The bootloader unlock process on this Galaxy M21 2021 Edition is same as mentioned in Galaxy M21 2019 thread ( https://forum.xda-developers.com/t/rom-full-oneui-10-totsukaos-q-for-galaxy-m21.4219975/ ) but none of the unofficial TWRP recoveries work nor does Magisk boot.img patch method work for rooting this model. Samsung does not support Fastboot as I understand & everything ends with Error : Signature verification failed. The only option left to me is sell off this phone but its so new.
If any developer can help me with some Custom Recovery that could install itself for rooting and perhaps custom ROM (I know I'm asking for too much ) for this device (SM-M215/DS), I will gladly donate $20.00/month for a year (Pls consider the bad times of pandemic we all are in). As right now I've put up this device (SM-M215G/DS) for sale. I've attached a few screenshots of the device maybe it could help any Dev who's interested (Hopefully ).

Firstly, I THANK YOU for replying to my desperate post. I'm delighted that Dev (jwoegerbauer) wanted to help.
Coming to the topic, Yes I was aware that rooting didnt require Custom Recovery.
1> I had tried to install Magisk_V23.zip via command [adb sideload magisk.zip] but the
response I had got was [Error: Signature verification failed, Error: Aborted.] on this device
(SM-M215G/DS).
2> When I flashed couple of TWRPs (one official for Galaxy M20 from www.twrp.me & few
unofficial TWRP builds from the net) via latest ODINv14.3 , ODIN displayed PASS! and
rebooted as I had kept Auto Reboot & F.Reset Time ON. But Native Android revovery came
on with Custom Binary Error. Again, I did the same with F.Reset Time & Auto Reboot OFF this
time and when I manually rebooted to recovery (Vol UP + Power) it was back to native
android recovery. I had to factrory reset to get the samsung logo then booted into welcome
screen.
3> I have checked the link ( https://forum.xda-developers.com/t/...al-adb-fastboot-
drivers.4185535/post-83851013 ) you provided. Awesome work! My questions are will it
enable FASTBOOT on SAMSUNG? Because when I select Reboot to Bootloader option in Anroid Recovery the phone does go into Fastboot Mode but apparently Fastboot seems
disabled by Samsung because from the PC it does not recognise the Fastboot Devices. So,
as a noob if I've understood whats mentioned in the link you provided is that Samsung didnt
provide the Native Samsung Fastboot Drivers for the Galaxy M21 2021 DELIBERATELY? So,
the link you provided will help me install the required Fastboot Drivers? & then I can flash
TWRP.img or Magisk.img?
Thanks in advance

Followup 1:
Hi, I tried your ADB-FASTBOOT-Installer but it doesnt seem to go beyond "Waiting for devices" screen.
1> I tried installing magisk v.19.3.zip (renamed to just "OTA") using command (adb sideload OTA)
first error i got was (adb: failed to read command: No error)
2> second time i tried installing from another folder belonging to 15-seconds-adb and it showed [ (0.01x) success ] something like that
3> I installed magisk manager 2021.4.9 Magisk v22.1 by Package Installer method not sideload method. When i rebooted & checked magisk manager it wasnt rooted so I tried boot.img patch method and got error: unable to unpack boot.img
I have attched some screenshots of the errors but what I understand from this is that the new Samsung devices might have img files written in some new format i guess because why else would magisk manager fail to unpack and patch a boot.img file, ususally it does fine.
I have also attached a copy of the device stock boot image file (hope i'm not breaking some xda rules here about posting img files , i just joined yesterday so )
Maybe its of some help to some Dev who might need these to find a workable solution.
The stock firmware I downloaded is flashing well on the device (SM-M215G/DS), the link is here- https://samfrew.com/download/Galaxy__M21__2021__Edition__/lOg2/INS/M215GDDU1AUG2/M215GODM1AUF3/

Well what necessarily needed for rooting an android phone is just modifying some files in /system? I have seen the phrase 'toybox 0.8.5' a multiple times in your posts, not sure what is that.

Toybox is a replacement for many Linux command-line utilities that is targeted at embedded systems - similar to BusyBox. It was created by Rob Landley, who is also a former BusyBox maintainer. Toybox is merged into any Android starting with version 6.

Sorry to barge in LR7875, to my knowledge (I have rooted & installed Roms on some older Samsung/Redmi/Laptops etc.) rooting is the process through which we gain Admin Rights / Super User on Linux devices. Correct me if I'm wrong. Im not a programmer by any means so.

Hi there jwoegerbauer, thanks for responding. If im not being bothersome , I'll need to stalk you on XDA for some help on this issue of rooting this device, if it s okay with you . Pray tell me what else other than magisk could root this stubborn Samsung model ? Im getting some good offers for this device on the local online market but i really didnt want to sell it off just wanted to root & install roms like before.. Other than magisk I just know of SuperSU by chainfire which I think stopped working well post android 8 oreo but will it work for Android 11? No way any changes to /system/Priv-app and the phones factory reset themselves. One-Click Root only takes calls & they charge $50 for rooting, but whats the guarantee if we pay up that theyll root it properly & taht too it would be just root not Recovery or ROMs. I'm lost.
Installing Magisk DOESN'T ROOT Android. Installing SuperSU DOESN'T ROOT Android. POV.
To have said it:
Magisk is successor to XPosed, means a software framework what once get added to Android allows you to systemless apply modules, means some functionalities modders are missing on standard Android. The crux with Magisk is it patches device's bootloader.
SuperSU simply is a per-app root-access management tool, nothing else: it requires Android got rooted.

How are you "flashing"?
Why do you say it "is flashing well"?
As far as I know, you need to use Odin (on a PC) to "flash" a Samsung device. Samsung does not support fastboot -- no amount of updating drivers on your PC will make a Samsung device start supporting fastboot.
Magisk is much more than just a way to root, but a side effect of installing Magisk is that you will be rooted.
If you have installed the Magisk Manager app and tried to patch the AP.tar of the stock firmware, and you are getting an error, you should look through the main Magisk thread, and maybe ask there.

IMO you're WRONG: Magisk DOESN'T ROOT Android, but you additionally can install MagiskSU app what grants elevated rights ( AKA SU ) to Magisk.

I need to hop on and correct a few details here...
Magisk is not a successor to Xposed. That's like comparing apples and oranges. If you want to know how Magisk came to be John has written about that in a couple of places, here for example:
Spoiler
https://www.reddit.com/r/Android/comments/7oem7o
And Magisk does not patch the bootloader, but the ramdisk which can be found in either the boot or recovery image depending on your device. Details about that here:

True . Don't quote me, (In a nut shell ) up from Andoid 9 (Pie) modification to /system /app etc. is difficult per my knowledge, thats why probably magisk sits in the boot partition, no one dare touches the system partition anymore while the gadget is ON. Only Gugle stays in the system partition im sure. The Custom Recoveries do wipe the device but are unable to erase the core andoid OS inside . Even 'Fastboot Erase' command cant get andoid out completely (exception Linux-phones i think). So practically Andoid devices are just gadgets that are 'leased' to the so-called 'owner' of the device (without explicitly mentioning the term 'leased' by gugle). The cost of the smart-gadget is practically the 'Down Payment' we pay to Gugle & OEMs then the rest of the revenue they make from Ads etc. which goes as 'Rent/lease payment' to them ultimaately & we never get to own the devices we purchase EVER! .
My sixth-sense says The chinese OEMs allowing Fastboot Mode only for now but only to make inroads into the smart-gadget market, once they have made everyones profile Gugle & pentgon might just make the softwares on these smart-gadgets wholly tamper-proof & focus more on 'managing' or keeping an eye on their 'subjects' [given that the whole gugle business,- 'search-engine', 'smart-device' etc. started officially in 2004 which was POST the 9.11 ATTACK].
So they're probably maintaining the Big-Data on everyone who uses their devices & 2014 is when data-warehousing became the need if i remember correctly; so, it was all about compressing the Big-data gathered & then Analytecs took the spotlight by 2016-17 coz they needed to analyize all the data collected & remove the junk from it then home in on pentgons targets. It's Obvious . No wonder they're pushing PX-Xperience ROMs through the ROM channels to cover the gap created by chinese OEMs eating into their market share. Why else do they charge other OEMs $2 for OTG-support while Shamshung (and now MYUI) already had native OTG-support on their devices shipped? so that's what Sekure-folder all about, YOUR DATA LOADED & LOCKED real-time then SHIPPED back to Gugle-Analytecs. Obvious.
Well so root is basically... Removing those ads and trackware up to the bare bones of the phone, to ensure all your data isn't used to make the spammy advertisements?
Android is nothing else then a derivated Linux. In the world of Linux the Root User is the user that has all rights esp. accessing / modifying system files, it's comparable to the Administrator in the world of Windows.
In the world of Linux this Root User typically is called superuser ( commonly abbreviated: SU ). In the world of Android such a superuser isn't in general implemented by default: it must get added to Android by modding it, means adding a SU ( read: Switch User ) binary - in whatever form - to Android what is systemwide accessible. In the world of Android an user root exists what is the user with user ID 0.
