Bootloop after flashing patched boot.img through Odin (SM-T860) Magisk V20 - Samsung Galaxy Tab S6 Questions & Answers

I tried rooting my Tab S6 Wifi (German, Snapdragon with unlockable bootloader) following this guide
unofficialtwrp.com/root-latest-samsung/
after another guide i found on xda left me with a vbmeta error to which i couldn´t find a solution (except maybe patching version 19.4 instead of 20, but the manager won´t let me choose and i don´t know how to do that manually).
SImply flashing stock firmware still works, but i´d really like it rooted. Is there something i need to do differently?
This isnt my first time rooting, it is however my first time being left with unanswered errors, so my experience is limited.
I can try to provide any information you might need.
Thank you for your time and patience.

Alternatively, if someone could provide me with a patched AP file that doesn´t cause the vbmeta error that fits my device, that would most likely work even better.

Unbrick Assistance Thread

Bricked your M5? Post here. I am one of three posters who have posted threads requesting assistance - we might as well create one thread where we can try and help each other.
My model? SHT-AL09 (C636). My story? I apparently made a bad change to my build.prop file, and had USB debugging disabled. I then probably dug myself a deeper hole trying to recover. I don't even get boot animation anymore. I'd happily pay someone to unbrick me.
The only potential progress I have made, is that I was able to install and successfully boot TWRP - although TWRP detects that I have no operating system installed and I am unable to mount any partitions except for my external SD card. Using TWRP's file manager, I can see that the system partition, for example, has not been entirely wiped, but many files seem to be missing. At the very least, TWRP allows me to turn the screen off without seeking to contantly reboot thereafter.
To install TWRP, I followed these instructions intended for Mate 9 owners:

This is TWRP to Mate 9/Android O, brought to you by FunkyHuawei.
It's just a preliminary build so I can't promise anything/everything will work! Keep that in mind. I'm not responsible if you brick your device.
EDIT: Does not work with Mate 10 series.
DOWNLOAD LINK:
https://drive.google.com/open?id=0B45NCsO2AL_1NEh2aDFLM3JlYkU
It works on the Android O build here:
https://www.reddit.com/r/FunkyHuawei/comments/75uwkd/october_12_first_official_android_o_beta_for/
and the official European beta.
To install:
First, have Android O running. Unlock the bootloader. Download the twrp image.
Then, run in fastboot mode:
fastboot flash recovery_ramdisk twrp_android_o_mate9_a1.img
Then, reboot holding volume up, and you've got TWRP!
Note: With the Android O update, it is no longer possible to flash the recovery2 partition. Furthermore, the names of the partitions have changed. Please keep that in mind, and don't mess around too much with TWRP, to be sure you don't brick your system!

Hmm ... I wanted to ask you whether you have the full OTA package for your device? So you should be able to extract all the partition images from there and to fastboot flash them. But I checked on HFF and I do not see a full OTA package matching your device yet.

I've tried flashing system.img/ramdisk.img from the c00 package. Maybe I have to wait for c636 firmware, or maybe I have to flash additional .imgs. I am pretty sure that the specs and hardware I have are the same as the c00.
I've tried flashing the entire update.zip file in TWRP...but as noted TWRP is unable to mount internal storage. I'm not sure if I need to wipe and reformat first. I also have no clue whether the TWRP build I installed is properly compatible with the device. I had nothing to lose by giving it a shot.

This will not work as the boot chain will be broken due to mismatching checksums. You need to have the correct images. To flash a OTA image you also need to have the standard recovery image installed ...
So...will someone correct please correct me if this is wrong?
If I were to flash a c00 oeminfo file, I could then install a c00 update.zip via dload folder?
Would c432 work as well (with a flashed oeminfo), even though the Euro hardware has different bands than my hardware?
There is now a full OTA on FF for C635.....still nothing for c636...
Finally, a full OTA is available for c636.
But the 'dload' method (update.app on an sd card) failed at 5%. And flashing ramdisk/recovery/erecovery/system images also failed.
Is this possibly because the OTA is B153, whereas my M5 was shipped B121?
(I hate to be that guy bumping his own thread, sorry)
I'm unbricked!
For those in a similar spot, looking to rebrand, or otherwise interested...
I finally e-mailed Funky Huawei for assistance. Their unbrick tool did not work. However, their e-recovery method worked perfectly (basically, you point your router's DNS to Funky Huawei, enter stock recovery and connect to wi-fi, and Funky Huawei's servers mimic Huawei's servers. If they do not have your firmware on their server, they will add it by request (provided it exists on the internet).
I paid $65 for a 30 day pass - a little steep, but I was impatient. I'm not sure if I could have gotten away with paying less. If you want to try and use my FH account over the next 30 days PM me (although I don't want to get carried away with that).
For those looking to rebrand, if you can flash an OEMinfo file successfully (FH has a rebrand tool and I have no clue how well it works), you should be able to use FH's erecovery method to flash firmware (don't blame me if something goes wrong).
One reason for the trouble I was having, if because I bootlooped after making a change to the vendor/build.prop file. This file was on the vendor partition, not the system partition, and for whatever reason the vendor partition cannot be flashed via fastboot (in theory it can be flashed, in reality it returns an error that doesn't have to do with the size of the partition).
Before reverting to FH, I finally got TWRP installled and functioning, and after all the attempts I made to recover my device, the same build.prop file which initially caused a bootloop was still in the /vendor folder. And TWRP wouldn't mount the system and vendor partitions as read/writeable - that was frustrating.
Now off to experiment with AOSP GSIs while I feel like I have little to lose...
Please help me
hello everyone,
i tried to rebrand my m5pro with help of ministryofsolutions. Something went wrong and my tablet (CMR-AL19) is stucked in the recovery mode. how can i fix it? Someone who ca help me? I will pay

(Almost) bricked Oneplus X: cannot unlock bootloader, cannot install OS

Hi all,
tl;dr: Tried to hard unbrick my Oneplus X, which was partly succesful (no OS is installed in the process, while there should be). I am now stuck with no OS and only the Oneplus recovery. I want to install an OS, but it says my bootloader is locked. To unlock it, I need an OS ==> vicious circle.
Full story below:
Recently I've decided to reinstall LineageOS on my Oneplus X because I had quite some problems with it (battery drain, apps crashing, wifi slow to connect, ...). I've done it like 5 times before on this device for various reasons, so I didn't expect any problems. I had LineageOS 14.1 and TWRP 3.0.3 installed. When I wiped everything, I wanted to flash the ROM I had ready using TWRP. However, gave an error number 7, saying that the ROM is not compatible for the device, which I am sure was. Remembering I had a similar issue a while back, I installed flashed an updated version of TWRP (3.2.2) using TWRP itself. That was successfull, but here's where the trouble began.
I noticed that TWRP didn't recognise any storage (Internal storage, SD card and USB-OTG all showed up as 0 MB) any longer. Neither could I mount any of the storages. I've tried a lot of things to solve this. After a while, I decided that the only hope left was the 'mega unbrick guide' (https://forums.oneplus.com/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-x.417648/) which claims to be able to recover any device, unless it has a hardware problem. I got good hope as I got near the end of the guide. The last step says 'Disconnect phone from PC and boot into system', but here I got stuck on the Oneplus boot logo, making me think that there is no OS installed on the device.
I can still access the recovery using power button and volume down, but the recovery that the mega unbrick guide installs, is the limited Oneplus recovery. It allows to install a ROM from the local storage, or from USB using adb sideload. When I try option 1, nothing happens, no new screen opens or anything. When I try option 2, I enter the adb sideload mode which would normally allow me to sideload a ROM using my pc. My pc confirms I'm in adb sideload mode, and I try to sideload a ROM. It starts fine, but after a few seconds, it says 'Installation failed'. I've tried stock OOS, latest OOS as well as LineageOS 14.1 that was installed before.
Another thing that I can do in the Oneplus recovery is rebooting into fastboot mode, where I should be able to flash the recovery of my choice. Again, my phone confirms I'm in fastboot mode and I try to flash or boot TWRP recovery, but I get the message: 'FAILED (remote: Device not unlocked cannot flash or erase)'. Okay, seems like the bootloader is still locked, so I should just go and unlock it using 'fastboot oem unlock'. This gives the message: 'FAILED (remote: oem unlock is disabled)'. I've been searching around a lot on the internet, and it seems like the only way to enable oem unlock, is in the OS itself in the developer settings. But the problem is, I have no OS and cannot install one because the bootloader is not unlocked... So I'm stuck in this vicious circle.
I've been searching on the internet for hours and starting to lose hope. At this point, I would be happy if I can just have any OS (OxygenOS or LineageOS or something else) running. If I have that, I should be able to take it from there.
Any help is much appreciated. Thank you very much.
Kind regards,
Jeroen

Update:
Oneplus support could solve the problem for me! Or at least, partly. It appears that Oneplus has an updated version of the tool used in the mega unbrick guide: MSMDownloadTool V2.1 instead of V2.0. This tool did it's job perfectly, OOS was also installed, in contrast to V2.0 of the tool. I ****ed it up again after that (oops), but found the tool V2.1 online here (https://github.com/finlayacourt/Oneplus-X-Recovery). Some files are missing here like the system.img, but I just copied them from the folder of tool V2.0 found in the mega unbrick guide. It didn't work as perfectly as Oneplus's tool, but at least I was able to install OOS from the Oneplus bootloader, which I wasn't able to before. So knowing that, in the end, the result is the same as for their tool. A working OS again, perfect! So now I can unlock the bootloader again and continue the adventure.
Now, what I've found is that the mainboard I have on my OPX is a newer version (if you search on Google for 'oneplus E1003_15', you'll find some things about it, not much though). I'm 99% positive that this caused all the problems I've encountered. It is why TWRP couldn't see any storage, why the stock Oneplus recovery couldn't see any storage, why the tool V2.0 didn't work and why V2.1 did work. If I wanted a working TWRP, I had to install a modified version of TWRP which is compatible with the newer version, from here: https://www.android-hilfe.de/forum/...-1-oreo-rom-unofficial-onyx-8-1-x.867374.html (yes, once you're relying on German sites, you know you went very deep). After that, I could install LineageOS 14.1 again. I was unable to install the unofficial LineageOS 15.1 however, but knowing where I came from, what I've gone through and how much time I've lost on all of this, I think I'll just stick with LineageOS 14.1 until this baby can retire...
Got to say I only have very positive experiences with Oneplus and it's customer support, and this only adds to it!
I hope I can also help other people with the same problem.

Greatly appreciate your feedback here. I think that I am in the same situation you were. Used what you suggested - using MSM v2.1 that you provided with the system.img, non-hlos and userdata.img from MSM v2.0. The process ends with "Download Complete" written in green but when I check "Verify" it fails exactly @system.img, userdata and non-hlos. I can't boot recovery either after these.
Do you have any clue as to why it is so?

As far as I know, I haven't used the "Verify" button. Right after the green "Download Complete" line, I booted into the OOS stock recovery by pressing volume down and power button (I think? Not sure anymore, I always forget it). From there, I could install OOS with a official ROM image.
Are you sure you moved the correct files from V2.0 to V2.1? The way I knew which files to move, is by first starting the V2.1-program without any added files. Then it told me 'system.img missing' (or something like that), so I knew I had to add that. After adding that, I ran the program again and added the next file it said it was missing etc etc.
Sucks to hear your recovery process doesn't go as "smooth" (it's all relative of course) as mine.

Hah, did not expect an answer, I've seen your thread on oneplus forums as well, glad you were so quick to answer here. I've found the MSM2.1 uploaded in a google drive with all the files afterwards, after some long hours of searching too. Anyway, I still can't adb sideload anything, the storage seems 'corrupted' to say the least, but there are imporvements from MSM v2.0 and v3.0 flahses. The recovery menu works flawlessly now, no artifacts or freezes, also the phone 'almost' booted. It went to the "Updating android apps" thing.
I don't really know what to do next. Recovery does not help me at all. I can't sideload anything, it renders a "protocol fault" error. Internal storage has 2 empty folders within and that's about it. Also the bootloader is locked now and I can't make any use of fastboot mode.

Haha I know the feeling! But thanks to e-mail notifications.
I also thought that my storage was corrupted at first, given the symptoms I described in my first post, so I didn't expect my OPX to be revived, but hey it's still alive now.
I also had the locked bootloader-thing. The way I could unlock it, is by first installing OOS using the stock recovery (which was installed using the tool), then unlocking it in OOS, so I could install another recovery and eventually another OS.
I'm afraid I already explained the problems I encountered and the procedure I followed pretty detailed. If you have anything that deviates from this, I'm sorry to say that I can't really help you with that, even if I wanted to. Did you perform the exact steps I mentioned (including the V2.1-tool that I linked to)? What exactly do you mean with the "3.1 flash"?
It's also already 2 months ago, so I don't even know exactly what I've done apart from what I've described...

It was a typo, I meant v2.0 and v3.0(for oneplus 3). The op3 unbrick guide suggested that the v3.0 might work for oneplus x as well, so I tried that out too.
Anyway, I've done the process a couple more times and the phone booted untill you set the device up, when you are finished it just reboots. I can see the lock screen, I can't bring down the upper bar or enter the settings, if unlocked it prompts me to the first time set up and upon it's completion the phone reboots. I wiped cache,data did a factory reset. Now it's back with the recovery menu artifacts and not booting anymore either. I will use that tool a couple more times then I am done until further suggestions from this forum. After all, my life does not depends on reviving it, I was gonna give it to my brother, who shattered his phones' touchscreen, until he repairs his. Thank you again for replying, no need to reply to this, unless it can help my case.

Root/Unroot frustrations

I'd like to keep this simple. I tried rooting and not a single tutorial on here has ended with root privileges for various reasons. I'm done with it. I flashed stock firmware in hopes of removing any trace of files that may have been altered during the various root tutorials I followed, but Samsung Pass says the device is still rooted.
What do I need to do to return to 100% stock?

I assume you unlocked the bootloader. Try Relocking and flash the firmware again.
Weather that will work is anybodys guess.
Rooting is a pretty simple procedure I can't think of any reason it didn't work except user error.
This method works perfectly on T860.

Well, this isn't the first time I've rooted a device and I followed every step of every tutorial I found on here and, for some reason, it would not root. This is the first, and only, device I've had this much trouble with.
The tutorial for rooting without TWRP: I made the patched AP file and flashed it; however, I could not boot into recovery or download mode and it always stuck on the boot logo.
The tutorial for installing TWRP didn't have a link for the encryption disabler and the one I found did absolutely nothing and the folders in storage just showed as a string of numbers and letters.
Maybe, if someone could put together a full tutorial with the files being used within the tutorial, it would have worked.

Did you get the bootloader unlocked?
Unlocking the bootloader:
https://www.getdroidtips.com/how-to...to_Unlock_Bootloader_on_Samsung_Galaxy_Tab_S6
To get to download mode it's volume up and volume down then plug your pc into device. NOT POWER AND VOLUME DOWN. This can be a pain in the back side.
If you do it this way you'll get the option unlock / lock bootloader or go to bootloader mode.
If you follow the instructions perfectly and then follow the instructions for rooting it will work.
Move on to root.

Yep, bootloader unlock was easy. I'll give root another try with your steps in a couple of days when I'm off work. Sorry if I came across a bit aggressive in my previous posts; I have a tendency to do so even when I'm not frustrated.
This has been so frustrating to me because I know rooting is usually a simple process; as you said previously.

So, yea, I'm a bit late getting around to this. Sorry.
This is where things get hung up. Everything flashes just fine and I can even get into TWRP; however, when I try to boot the tablet i get the Galaxy Tab S6 screen, then the warning about the bootloader being unlocked, and back to the Galaxy Tab S6 screen but with a "unofficial software" warning....and repeat. It just boot loops and this is where I've since I started this thread.
Also, returning to stock doesn't completely remove root traces as I can't use Samsung Pass and I simply get a warning about the device seemingly being rooted even though it isn't.
If you installed TWRP, then you tripped Knox tripping Knox will permentally disable Samsung Pay as far as I'm aware. You'll never get it back, regardless of root or no root access.
Also, I'm not sure why you're installing TWRP AND trying to flash a Magisk patched OS. It's one or the other, you don't need to do both. Unless something has changed in Android 10?
If you're flashing TWRP, you just need to flash Magisk in TWRP(along with the other files!), no need to patch AP.

Not Samsung Pay, I couldn't care less about that, but Samsung Pass; I guess it looks for knox being tripped now too. That sucks, but I'll make do without it.
I was following the guides posted above. The root guide said to flash a Magisk patched OS and then there was a guide for installing TWRP. I never had this many issues or this much confusion with my 1st gen Tab S; maybe I just haven't kept as close of an eye on these things since I've been without a tablet for awhile before getting the Tab S6.
Anyway, for clarification, all I need to do is flash TWRP and then flash magisk from within TWRP? Or, just install the magisk apk after booting into Android?

I never had this many issues or this much confusion with my 1st gen Tab S; maybe I just haven't kept as close of an eye on these things since I've been without a tablet for awhile before getting the Tab S6.
Anyway, for clarification, all I need to do is flash TWRP and then flash magisk from within TWRP? Or, just install the magisk apk after booting into Android?

My bad for some reason I just read that as Samsung Pay. But yeah Samsung Pass also doesn't work with root, I'm not sure if that is permanent though as I've never used Samsung Pass, but did come across this thread https://forum.xda-developers.com/general/rooting-roms/samsung-pass-knox-tripped-devices-t3687977 it is possible to get some components of Knox to function again, (I have a working Secure Folder) so might be worth taking a look.
As for you question...
You should give this thread a good read... https://forum.xda-developers.com/galaxy-tab-s6/development/recovery-twrp-3-3-1-t3975587
Basic steps are... Unlock the bootloader and then boot into system and ensure it's unlocked in settings. You may need to connect to the web, I can't remember tbh
First you need to install TWRP, once that is done you need to reboot but YOU HAVE TO boot directly back into TWRP. You cannot boot into system, or TWRP will be overwritten by stock recovery and you'll need to start over again. Once TWRP is installed, boot into TWRP and format data then reboot recovery, flash Kernel then flash encryption disabler then unmount the system and flash Magisk 20.4 - Finally reboot to system.
I'd seriously and strongly suggest reading that TWRP thread to ensure things go smoothly.

I'll give those threads a thorough reading over tonight and tomorrow night while at work and then see if I can get this all sorted out Monday when I'm off. I remember Pass still working with root on the original Tab S so I'm hoping it hasn't changed.
Thanks for jumping in to try and help me with this. I'll update within a few days instead of months like my last update. ?

It has definitely changed. Pass doesn't work on my Tab S6 and I'm rooted, I guess Knox is now integrated with alot of Samsung apps now. Not sure if it's possible or not to get it working again though, I've never bothered to research it as I don't need it for anything - But as I said, I got Secure Folder working again, so there's some hope for Pass I guess - That first thread I linked looked promising, but I only skimmed it, because frankly I'm not interested.
If you need anymore help, report back -I'll try my best. Also, the TWRP thread I linked is full of helpful people. :good:

Perhaps I'm just not meant to have root with this device. Flashing that kernel causes Wifi not to work, but it does boot. Not flashing the kernel also booted, but I couldn't install Magisk Manager. Other than the bootloader still being unlocked, I'm back on stock firmware.

What firmware are you running?
I remember seeing something about one of the newer Kernels effecting WIFI on Android 10. Assume you're running that?
If that's the case, give the TWRP thread a browse - You maybe able to find an older version of the Kernel that'll work - As far as I'm aware, an older Kernel than what you currently installed will work, but a newer version than currently installed will possibly cause bootloop.
I can't help much with Android 10 specific stuff as I'm still running Android 9 because it's stable.

I am definitely on the latest Android 10 update so I'll see if I can find an earlier version that will work. I'll see what I can find out on the TWRP thread.

If you can't find an older Kernel (I'm not sure there is one for Android 10), it may be the case that you'll need to wait for the Kernel to be updated.

Yea, it looks like Samsung made some "wifi improvements" in OneUI 2.5 and that's causing some kernel issues preventing wifi from working. I think I could find a kernel fairly easily, but I think I'm just going to wait for a kernel update. If it never comes, I'll find an older kernel. Thanks for the help!

Completly lost trying to root G715FN

Hello,
Let me try to recall everything I tried.
The first thing I have done is to unlock the bootloader. I had 0 troubles with that. But after that, I tried to root the phone and there is no luck.
First thing I found is that there is no dedicate root tool for this phone. So my first option was patch boot.img with Magisk. I done that but it give me an error with vbmeta verification.
I read some guides related with TWRP but had almost the same issue. I also tried to port myself TWRP with the same luck.
So after that, I though the better idea is was to built the house from the ground, not from the roof so I started searching about VBMeta and that stuff. I'm not very sure what's VBMeta or what it does but AFAIK, it's something that check several firmware integrity (maybe CRC?) and, if it's not the correct, it will say so and don't let you begin the phone. Several investigations later I found out that I have no clue on how to path/change/whatever VBMeta in order to flash a patched boot.img with Magisk root and so, I can't install/port TWRP.
I'm so sorry for posting this here and I know that there is tons of tutorials but that's my main issue: I find several guides, some for some phones (PCBs), some outdated, some without complete information... If you could point me out on the correct direction and help me with this I will really appreciate that.
Thank you in advance.
Bump!
I know you already sold this phone, but I post answer for other people reading this thread.
I described rooting method for this phone here:
Is possible to root Xcover Pro?
Hello, I have unlocked the bootloader. I tried to do the steps with Magisk, this is it: -Install Magisk. -Patch AP. -Copy it to PC. -ReFlash with ODIN. But when I do that, I got errors during installation on Download mode and the phone...

How to Update after Root

Hello everyone,
i am new to the device and i have read the threads on unlocking BL & rooting. However, I am still unsure about how to update the device after rooting. Can someone please write out a high level few lines?
You flash the stock firmware then root it again.
Well Id though Id done this enough for that to be a simple job (I did manage to root the device the day I bought it..) But I seem to be having an issue reflashing the boot.img back to the device using Fastboot after updating OTA to 12 .Any ideas?
Well I'm completely out of ideas. I've tried Canary build of Magisk, I've tried using the patched boot.img (waiting on any device eternally in Fastboot).I've tried patching the AP file (as .md5 and as .tar) Process fails each time.....
I was on Rooted 11 but I thought I could UNroot then grab 12 and REroot. Well I did actually have 12 installed (briefly) but now I've got an UNrooted 11, that just sux ,and I should've have never tried to get 12 lol. My BL is still unlocked of course so I just really want to go back to where I started if rooted 12 is a no-go for now. Any help would be greatly appreciated .
Ahalol I'm sorry for high jacking your thread but it said exactly what I wanted to ask :/
Thanks XDA as always!
I finally got it, all good.

For future reference for anybody who may read this in the future, updating a rooted Tab S7 / S7+ without losing your data is pretty much outlined step by step in the official Magisk installation guide.
Installation
The Magic Mask for Android
topjohnwu.github.io
Scroll down to the Samsung section, and then "Upgrading the OS". It's basically the same as Odin flashing the firmware as you normally would to restore to stock, except you're flashing the Magisk patched AP file in the AP slot instead, and using HOME_CSC instead of CSC in the CSC slot. CSC wipes data, HOME_CSC does not.
With the exception of a few weird Samsung devices (like the S6 Lite), don't listen to ppl who tell you to extract the boot image and flash separately. Just follow the *official* (I felt the emphasis was necessary here, again) Magisk installation guide in this case... Download the firmware file via Frija or whatever your source for firmware is (honestly dude.. just use Frija), extract the files, copy the AP file to your tablet (recommend adb push, not MTP), and use the Magisk app to patch the ENTIRE AP file. This is important because Magisk will also patch out other parts of the firmware like vbmeta, which is what allows it to work around avb restrictions. If you attempt to flash the full bone stock firmware and then a patched boot image separately, you will likely get an error that results in the need to wipe data, because avb (Android Verified Boot) has been violated without having had vbmeta patched among possibly other things, and then have fun with the misery of wiping and starting over... Anyway, after patching the FULL AP file in Magisk app, make sure there were no errors in the log (btw, this is where you can clearly see that Magisk is patching more than just the boot image...) and copy it back to your computer (again, like adb push was recommended before, use adb pull to move to computer), and then flash the BL / Magisk patched AP / HOME_CSC files in their respective slots (and CP if you have LTE model) in download mode. It'll reboot probably twice, then optimize apps before finishing booting to your updated system.
tl;dr - read the official Magisk guide I linked above (notice yet that I keep mentioning this?? lol)
My post is assuming you are on bone stock rooted ROM without custom recovery and/or encryption disabled mods and stuff (e.g. multidisabler mod). Every update for me goes without a hiccup, and I am fairly heavily modded with SafetyNet passing and everything (LSposed / GravityBox / Firefds kit / a bunch of Magisk modules). Loving that these tablets keep Widevine L1 even after rooting.. was my primary reason for buying! I also like / prefer the fact that my tablet is still encrypted without custom recovery so that the chances are my data is still safe should the tablet ever be lost or stolen. Anyway, if you do have custom recovery or flashed multidisabler already, I would definitely do your due diligence and research / ask questions to find out if there's anything different you have to do (different in relation to the official Magisk installation guide resource, or any pre-/post-install quirks).
Sorry, I know I rambled a bit but I hope this post is somewhat informative and able to be followed. Typing it from phone and browser is kinda glitching out. But I just felt the need to type this all out. It seems I don't see so much more misinformation on XDA than on the Samsung subforums lol. D:
