Did u do the part where u install magisk on the tablet and then patch the AP file, then send that new file called magisk something back to your PC?
[Samsung Galaxy Tab S8] belveder69:
yes i did
[Samsung Galaxy Tab S8] Daxorp:
I never have Magisk pre-installed in all rootings I have done, but it's always written. I don't know why!

But if I installed it manually, yes it asks to install tools and reboot, then the device is rooted.

Are you sure that you don't have root access anyway?
[Samsung Galaxy Tab S8] belveder69:
It's weird, Samsung Pass says it is rooted and so doesn't work but i tried 2 different root checkers and both say " root not properrly installed"

I haven't magisk asking to install tools either
[Samsung Galaxy Tab S8] lloydsw:
Has anyone updated to Magisk 26.0 w/o any problems?
[Samsung Galaxy Tab S8] hurray:
I have just upgraded Magisk from 25.2 to 26.0 on my Tab S8 Ultra without any issues (for now). The only preparation before the update was to restore the original Magisk app name.
[Samsung Galaxy Tab S8] kRel:
Hi . . .

I'm waiting for the tab purchased yesterday.

Since unlocking the bootloader erases the user partition, it erases any applications that may have been installed, resulting in a lengthy initialization of each application - for each app to install to which are added the numerous bluetooth pairings...

In my case more than 24 wasted hours :eek:

Regardless of installing root and recovery, which I won't do right away, is it useful, advantageous, to unlock the bootloader as soon as you receive the device so as not to waste dozens of hours afterwards?

On Samsung, does unlocking the bootloader void the warranty or activate some signal like the old yellow triangle? Is it reversible?

Thanks
[Samsung Galaxy Tab S8] Arealhooman:
1. Rooting, and even if your bootloader is already unlocked still requires a data wipe

2. When you unlock the bootloader, when ever you boot you will get a warning.

3. Knox should not trigger unless you root or otherwise modify software.
[Samsung Galaxy Tab S8] kRel:
So, with a new device, without user-installed apps and/or documents to back up, it's not wrong to forget about it and immediately unlock the bootloader...
[Samsung Galaxy Tab S8] lloydsw:
That's what I've done with my last two devices - skipped all setup until I unlocked the bootloader.
[Samsung Galaxy Tab S8] kRel:
Perfect ! Thanks !

That's what I wanted to hear! Does unlocking the bootloader have problems with Samsung? (galaxy Tab s8 ultra) Or are the problems encountered only at the root?
[Samsung Galaxy Tab S8] Arealhooman:
Rooting will require a data wipe, so your choice.
[Samsung Galaxy Tab S8] Arealhooman:
Unlocking bootloader only shows a warning. an fuse only gets triggered upon rooting (Tripping knox)
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
The short version of a much longer post I could write is that I kept on bootlooping on the new X900XXU4BWD8 (SM-X900_2_20230428104940) firmware (coming from the previous SM-X900_2_20230216135940) for my Tab S8 Ultra after flashing the updated, rooted firmware except for one seemingly random time it booted successfully, but a further reboot went back into bootlooops.

I then flashed the firmware using the unrooted AP file, but still the HOME_CSC, and then it said it was corrupt and needed a factory reset after all. After that, everything behaved normally.

Edit: And I had checked MD5 hashes of the AP file on both ends of the process, both before and after rooting it.

I haven't tried reflashing the rooted AP, or re-rooting the AP file yet. I'll try re-rooting the AP file, compare the hash to the already rooted AP file I have, and then re-flash it either way that turns out.

Edit 2: I re-copied the AP file to the tablet, checking the MD5 hash after, re-rooted it using Magisk 26.1, copied it back, checking the hash before and after yet again, flashed it, and the tablet bootloops a few times after Odin passed every check, then the tablet came to Android Recovery where it says data may be corrupt. Yay, again. :)

Tablet booted fine after another factory reset.

My next trick will be to re-download the firmware, allow it to be re-extracted / unencrypted, then I'll compare the hash of that AP file to the one got the first time, although I don't expect that to be an issue since the new AP worked fine as long as it wasn't rooted.

Edit 3: AP file has the same hash as before after re-downloading and extracting. Argh. Anyone else able to update to the new firmware rooted on any of the S8 models?
[Samsung Galaxy Tab S8] V0latyle:
Y'all have TWRP for this device, why aren't you just flashing Magisk in TWRP?
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
It's been so many years since I flashed a custom recovery and rooted with it, plus I didn't know TWRP for the Tab S8 had come that far (last I paid attention, it was still early in the development), I just didn't even think of it. I'll have to give it a try, although I'm not sure if I can necessarily expect a different outcome.

I'll check it out when I get enough time to fool with it.

Thanks!
[Samsung Galaxy Tab S8] V0latyle:
Even though the TWRP method is supposedly abandoned, it's still supported by Magisk. I've tried to root my Tab A using the "right" way of patching the AP file. Never worked properly. Flashing Magisk in TWRP on the other hand works every time.

Flashing TWRP isn't hard, you just flash the .tar in the AP slot using Odin.
[Samsung Galaxy Tab S8] lloydsw:
I don't know if it's what made a difference on my last update, but...

I had a bootloop after flashing & the tablet rebooting. Somehow I got it back into download mode & before I flashed it, I killed the auto-reboot option in Odin. When Odin was done, I rebooted by using Vol Up & power key. Seems to have worked.
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
Ah! I'll check out that suggestion, too. Thank you.
[Samsung Galaxy Tab S8] Zhono:
Not that it's the most helpful information, but I just figured I'd reply to say that I updated and had no issues. Did the same exact procedure as usual. Download with Frija, wait for it to fully decrypt, extract the zip, copy the AP over, patch with Magisk, copy back, flash with Odin. let it auto reboot. It did one bootloop from the Samsung logo screen (as it does for me every time I update), sat on said logo screen for a minute or two the second time, then booted in fine. Just still annoyed that you have to press the power button to bypass their bull**** bootloader warning every single time you reboot the tablet.

So definitely try re-doing the whole procedure with a completely fresh download/decrypt/extract.
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
Thank you. Hopefully I have time to mess with the tablet again later today.

I think I noticed it does continue booting on its own at that screen, at least eventually (maybe 30 seconds maximum?), but yes, it's extra annoying as if the previously existing warning, which is still there, wasn't annoying enough.

Edit: By the way, out of curiosity, are you using the latest Magisk v26.1 Stable, or an older version?
[Samsung Galaxy Tab S8] lloydsw:
Update to post #250: I just did another update this morning, and it's Vol Down & power to force a reboot while it's in download mode.
[Samsung Galaxy Tab S8] Zhono:
Definitely takes more than 30 seconds to boot past the Samsung logo after an update. It can take several minutes. And yeah, I had just updated to the latest stable magisk 26.1 right before I did the firmware update.
[Samsung Galaxy Tab S8] rappa619:
Is there an unroot guide? Also if we unroot and lock the bootloader again, will OTA updates start working?
[Samsung Galaxy Tab S8] sosimple:
Just flash the original rom again. Lock the bootloader again and probably Ota updates will come.

You better download the last rom, so you won't need any update.

How to do I am confused
[Samsung Galaxy Tab S8] szinyo1048:
Hello. I want to change fonts, and /system/media/audio/ui files. My X906B is fully rooted, but if i want to overwrite file in /system show me normaly: " remount system rw? " i clicked: YES, but cannot copy, cannot delete, or overwrite... Please guys help me, i want to change the files.

I dont unsertod: If rooted how to no acccess to /system with RW. I like all answer, please help me, how to do ( if you have time: step by step ) very very thank!
[Samsung Galaxy Tab S8] Chaser42:
The system partition should not be modified directly. Any changes like that should be done in a "systemless" fashion via a Magisk module. Magisk sort of fools Android and lets you make changes to system without actually changing anything on the pristine system partition.

Go over to GitHub and get the latest release of "Fox's Mmm". That app allows you to search for Magisk modules and install them. People have cooked up some really good modules that let you do all sorts of stuff. Hopefully there's something that will come close to meeting your needs.

[Samsung Galaxy Tab S8] dodeca:
I rooted my S8 Ultra according to post #3 in this thread some time ago. My Magisk, which is at 25.2, and my Magisk App, which is at 25.2, want to get an update (likely to 26.x).

My setup also involves stuff from "Step 5" of post #3 in this thread, i.e., the FoxMagiskModuleManager, the Universal Safetynet Fix, and Zygisk for Denylists.

Now, it is absolutely unclear to me and I am hesitant, if I can just boldly let the Magisk App do the update it wants to have. Will everything still be rooted and functional after that (only updated regarding Magisk) ... or will other things need to be updated/changed as a consequence of updating Magisk too ... or, even worse, will bad things happen to the rooted setup, as described in post #3 ?
[Samsung Galaxy Tab S8] rawley2314:
Hi, I'm in a situation where I cannot install magisk or any unknown apps on my galaxy tab, is there another way to patch the AP file?
[Samsung Galaxy Tab S8] ttesty:
Does this work for US models like AT&T ? I thought bootloaders were locked. @AndroPlus claims to have unlocked.

Others write: "United States Samsung tablets have OEM Unlocking grayed out, so there's no way to enable it. You have to get a Wi-Fi only model to be able to unlock the bootloader."

I checked, and it looks like it's a US model was used, but it's not a US Carrier Model... whoops.
[Samsung Galaxy Tab S8] ttesty:
Another problem is read only partitions on the S8 Tab.. Not a good solution for now. S7 Tab bootloader unlock will work out better for US carries.
[Samsung Galaxy Tab S8] grown_man:
You can update magisk and it's own app w/o any problems. I did w/o any problems. Nothing will change on your device (like root etc)
[Samsung Galaxy Tab S8] SingingDroid:
My samsung phone is rooted.

I uninstalled few junk system apps and now I am stuck at samsung logo.

So I can't patch AP.md5 file anymore.

Option1: Data is saved.

Can I use below files and still keep my data?

stock AP.md5 file,

stock BL file,

stock CP file and

stock Home_CSC file.

Option2: Loss data

stock AP.md5 file,

stock BL file,

stock CP file and

stock CSC file.

What are my options. Please suggest.
[Samsung Galaxy Tab S8] Nazzz:
So, I successfully rooted my Tab S8+ a couple of month ago (big thanks to the guide in post #3 (y)), and today I got a "Software Update" notification. This came as a surprise, as with all my previous rooted phones/tablets regular over-the-air updates were automatically disabled once I rooted the devices. But this time the tablet say that I can only postpone the update (not cancel) and that it will automatically install itself on Sep 1.

Granted, I left the option "Download updated firmware over WiFi" on in the settings, but again, I was under the impression that after root it won't matter.

So two questions:

Can I really not turn off and/or skip updates?

If I let it update on its own, it will break my root and/or cause bootloop? I absolutely need to follow the steps in the guide and update that way, otherwise I loose my root and/or have to factory reset?
[Samsung Galaxy Tab S8] arnersae:
This happened to my s20fe too, I fixed it by installing the update via odin after patching the ap file with magisk, and keeping my files by selecting home_csc. It worked great, and now I don't get notifications of new updates as you would expect.

EDIT: typos
[Samsung Galaxy Tab S8] sosimple:
If you freeze the update service with titanium for example, it won't asking you to update any more. At least this is what i do in all my rooted Samsung. Tab s8 ultra haven't rooted yet, but I don't think will be anything different.
[Samsung Galaxy Tab S8] Drukan:
I got the same update push, it will fail if you attempt it, then it'll just ask again later. I just updated it myself using the root instructions step 4. Use frija to get the update, extract, copy to tab, patch, copy back, odin, reset...viola! updated!
[Samsung Galaxy Tab S8] sarreq:
does any of this work for the S8+ sm- 808u?
[Samsung Galaxy Tab S8] Goobertron833:
I'm having issues with bootlooping, says the reason is fs_mgr_mount_all:M02R

Can someone smarter than me explain how to fix this?
[Samsung Galaxy Tab S8] gelomaon:
I got up until Step3.11 but it fails in Odin. It goes into soft brick but it can be removed by FRP HiJacker. Now it's on a bootloop. What should I do next? Would appreciate any help as this is my only device for uni. Thanks in advance.
[Samsung Galaxy Tab S8] Ghisy:
Hey,

I know this is a thread for the Tab S8 but I was wondering if the rooting guide can be applied to the Tab S4?

The Tab S4 forums are pretty dead and I never updated my tablet to Android 10 at the time. I don't use it much but I thought I'd do it at some point.

Thanks!
[Samsung Galaxy Tab S8] jmc2543:
Having issues with getting Netflix to work. I followed the directions but the play store certificate still shows "not certified." The DenyList dosent seem to keep the Google Play services .gms and .gms.unstable ticked after reboot. And of course im not even able to install netflix from the app store due to bad cert
[Samsung Galaxy Tab S8] benchic:
Getting an error "Can't load Android System. Your data may be corrupt" and I get a try again or factory data reset option which works when I click it however Magisk is not installed when I do that.

Followed the instructions exactly the way they are step by step. Anyone knows how to solve this?

Can I just install Magisk again and be done with it? I did and a root checker app said it's rooted. Why did I have to flash the patched TAR file with ODIN to begin with if I could have just installed Magisk?
[Samsung Galaxy Tab S8] metalblaster:
There seems to be an error with the latest firmware. If I had to guess, I would assume it's due to the firmware being android 14. While Magisk does support Android 14 on other devices, its possible that something is different on samsung devices. For now, the only thing you can do is revert the android 14 upgrade and root from there or just run stock until it gets fixed.

I decided to update today and laterally ran into the same problem. It seems that Magisk has a issue on the subject in their github. And from my experience just tonight, it also seems that using 26.4 the latest version of magisk is causing all sorts of problems even with the older builds of the fireware. Im going to try an older version, 26.0 and also see if I can maybe fix at least the older patch. If the older version resolves the problem, then maybe it will work with the latest patch as well. Will report my findings.

edit: I went back to V26.0 (I am sure a later version could probably work; 26.2 or something), and the prior firmware patch worked no problem. I am going to attempt to do the latest android 14 patch now with 26.0. If this does work, then its a problem with Magisk and not with the change to android 14 (this seems somewhat likely). Ill make a report to the Magisk devs if it succeeds.

edit: Indeed it worked for the newest firmware. Based on the issue in the magisk github, I would recommend using v26.0 and nothing later then that until they push in a fix. The issue started at version 26.1.
[Samsung Galaxy Tab S8] Zhono:
Yeah, same. I was excited to finally see the A14 update available, and rushed to download/patch/install it. Got a boot loop, where it was quickly showing the Samsung logo, and immediately rebooting, over and over in rapid pace. Tried reflashing the update in odin, but without the magisk patched AP file, figuring I could be, and then patch the file again. Instead, I got what looked like it was booting for a second, then it bootlooped some more, and then said my data was corrupt.

This is the important part, for anyone else that comes here because they have the same issue. If you use another device to patch the AP file again using Magisk 26.0, and then flash in Odin, when it is done, it will start bootlooping again. LEAVE IT. After it bootloops a few times, it WILL eventually boot back into Android and show the OneUI update/upgrade screen, and it will be back to working. Don't panic and give up, thinking you have to wipe your data.
[Samsung Galaxy Tab S8] blinthor:
Hi,

I have a problem with S8 (sm-x700). I uploaded the new Android 14 software. I rooted it without any problem, but storeplay does not have a certificate. You can't even install Netflix. I decided to upload the new Android 14 without root and still storeplay does not have a certificate. Could anyone help?
[Samsung Galaxy Tab S8] blinthor:
Previously, when I rooted on Android 13, everything was fine. There was root and there was a store certificate.
[Samsung Galaxy Tab S8] parwiinder:
How did you roll back Magisk? I have 26.4 and I need to switch back to 26.

I am also surprised that none of the downloaders (Frija or SamloaderKotlin) can find/download the FW. I grabbed the decrypted files from the internets.
[Samsung Galaxy Tab S8] sosimple:
So ,now we got android 14 ,and I'm thinking to root it some day soon, can we do it without problems or to wait?

Thanks,
[Samsung Galaxy Tab S8] kailashnj:
Guys - Does android Auto works with S8+ Tab. kindly let me know. Also will this Root work with even Android 14 (One UI 6)
[Samsung Galaxy Tab S8] ricpdjrr:
I just purchased a SM-X700 . It currently has A-14 . I would like to downgrade to A-13 and Root. I have only rooted a few pixels in the past and that was long ago. This is my first Samsung.

I am a little confused on how to find the correct firmware using Frija. when I enter my Model and CSC it only shows the current A-14 firmware.

How do I browse for the correct downgraded A-13 firmware for that device?

Additionally, I know I can not downgrade from A13 To A-12 on the pixels as there is a anti rollback issue. Is it tthe same for Samsung, or could I flash back to A-12 on my S-8 Tablet?

Thanks, Rich..
[Samsung Galaxy Tab S8] grown_man:
it shows only the last one

u can find previos firmwares here or here for your device
[Samsung Galaxy Tab S8] grown_man:
i have no problem with bifrost
[Samsung Galaxy Tab S8] ricpdjrr:
Ahh.. much better, Thank you. would you know if there are any potential issues in flashing from A14 back to A12 on te s8 tablet?
[Samsung Galaxy Tab S8] grown_man:
There's no problem(please check md5) , but it's better to back up your files before, just in case...
[Samsung Galaxy Tab S8] ricpdjrr:
Sorry, not sure what you mean by md5?
[Samsung Galaxy Tab S8] grown_man:
to check if downloded file is same/right/all. sometimes downloaded file is not complete, i believe u faced that downloaded zip file is broken/missing files inside.

for example:

for tab s8 android 12 europe last firmware is here You will see md5 code

when you download the zip file, its better to check via this post for example (or other methods).
[Samsung Galaxy Tab S8] ricpdjrr:
ah.. ok got it.

So I decided to just try flashing back to A-12 without root for now. Unfortunately that failed. here is the log.

I have not unlocked bootloader as I read this was not necessary for just flashing stock firmware. I have enabled the developer option for OEM unlocking to allow for unlocking bootloader. I did remove both google and samsung accounts before the flash as recommended. Could this be a FRP issue?

edit.. I also ran odin3 as administrator..
[Samsung Galaxy Tab S8] grown_man:
I think u should uncheck "re partition" in options tab
[Samsung Galaxy Tab S8] ricpdjrr:
That was not set. Just auto reboot and f. Reset time
[Samsung Galaxy Tab S8] ricpdjrr:
What did you use for firmware and what version of magisk did you use? I just tried rooting A14 on my sm-x700 and got stuck on initial logo and had to factory reset.

Frija did not have the firmware for my device "XAR" I got the firmware from samfw.com

I used magisk v26.4

Reading other posts I might need to try again with v26.0
[Samsung Galaxy Tab S8] ricpdjrr:
So after many many searches I believe going fro A14 to A12 is too much of a jump and will not work without some very special modifications. So Now I just tried to root to the latest firmware and failed on my first attempt. After reading through some oftthe latest posts It seems I might need to find Magisk v-26.0 to get it to work.
[Samsung Galaxy Tab S8] grown_man:
Umm, i saw something new for me also,

That says, we must use same binary /sw (it's a number), if it's different could see your main problem.

So you have to download firmware that have same binary as your's

About rooting, if I remember correctly, I rooted android 14 with magisk 26.4 w/o any issues
[Samsung Galaxy Tab S8] ricpdjrr:
On what device was that?
[Samsung Galaxy Tab S8] grown_man:
s8u
[Samsung Galaxy Tab S8] ricpdjrr:
ok, Thanks..

I tried it with Magisk 26.0 and the root went perfectly..

This is my very first Samsung and so I was not familiar with all of there restrictions. It seems absurd that they do not provide these Firmwares as freely as Android does and of course it is just my luck that the one firmware that frija did not list was for my device.

I was having a lot of trouble downloading the firmware from Samfw on my antique lap top with download times of several hrs. I then tried downloading on my s8 tab and could not believe the speed differences. the s-8 got it in less than 1 hr.

Anyway... I am rooted with A14 .... :) \

Thank you very much for your help and of course a big thanks to the creators of this guide... @skrowl guide was easy to read and follow and was absolutely spot on..
