Hello,

I'm relatively new here in XDA and rooting. I have read all the posts here regarding the guide and have a few questions:

My Device is Samsung Galaxy Tab S8+ SM-X806B (Philippines)

1. in-case I don't want my device to be rooted anymore and want it back to shipped / factory condition, how do I do it?

2. What are essential things I can't do once my device is rooted?

3. Will lucky patcher, patcher for android work (please see screenshot below)?

Thanks in advance!

To be clear, you can't 100% put the tablet back in factory condition since Samsung implemented "KNOX" years ago. It's an "e-Fuse" which unlocking the bootloader permanently burns, and there is no way possible to unburn it. This tells Samsung that the device has previously had its software modified, even though it's not necessarily modified anymore.

There are more things listed below, but the obvious thing they might not mention is that you can no longer automatically install updates to the tablet when rooted. You have to follow the applicable steps from Post #3 to manually re-root and install the update using Magisk and Odin.

I did some Googling and found this regarding both re-locking the bootloader, and what gets broken by unlocking the bootloader in the first place. This was for the Galaxy S10, but hopefully it's similar enough on the Tab S8:

And apparently that article got the steps to re-lock the bootloader (on a Galaxy S10) right from a post on XDA:
[Samsung Galaxy Tab S8] UmiCat:
Just an update: earlier in this thread I placed a few posts about not being able to unlock the bootloader of my new Tab S8 5G UK model. My problem was not to find an option to lead to 'Unlocking Bootloader?' page on Download mode. I ended up getting another one from another shop. And everything worked flawlessly. I still don't know why my tab no.1 had the restrictions. It wasn't meant to be SIM-locked (or at least my SIM was recognised). IMEI and everything else indicated it was brand new and a UK model. The only difference is tab no.1 was bought from a smaller shop with a good discount. Anyway it looks like there is something we consumers never know!
[Samsung Galaxy Tab S8] patrickvu:
I successfully rooted my device (Tab S8) yesterday. But now I'm getting the dreaded 'custom binary (vbmeta) blocked due to remaining installment balance' (KG status: active) after a reboot. Loaded official firmware and now it boots. Should I wait 7 days and hope that the issue will go away or return it? Or is there anything else that I can try?
[Samsung Galaxy Tab S8] sosimple:
Question: I saw some pages before, that Netflix shows: max resolution =HD. Is it the standard of what Netflix app shows there? Because Netflix is also 4K. Or if you root you can't go above HD?

Thanks,
[Samsung Galaxy Tab S8] shadowofdeth:
Any custom kernels or anything? Just got my S8+ and it seems pretty unremarkable so far. A bit stuttery and laggy too. You can definitely tell Samsung gimped the the chip and this oneui or whatever doesn't help.

If no kernels can CPU governor at least be set to performance mode? The root process looks like a pain compared to what I'm used to with my OP phones.

Edit: Yes you can. Sort of. Definitely an improvement though.
[Samsung Galaxy Tab S8] Chaser42:
How you doing with your Tab S8? Have you been able to see the OEM Unlocking switch yet? I've got the regular Tab S8 WiFi only model (SM-X700) and the root process went pretty smooth. I did have the benefit of having already rooted three of the Tab S7+ models earlier this year and it was the same process. On each device I made a few lazy human errors which caused me to get stuck and made me a bit frustrated. But when I go to the process and make sure I do it step by step exactly I find my mistake and everything falls into place.

If you're still stuck, let us know. I'm sure one of us can figure out why you're stuck at that step and get you past it.

[Samsung Galaxy Tab S8] mossyhorn:
Hi, I'm very new to this site and rooting devices in general, but I was looking at tablets to purchase recently and found the Samsung Tab S8 thinking it looked nice; however, I wanted to root my Samsung S22 earlier as well and this didn't work. I purchased it (the Samsung S22) after looking online and finding documentation saying I could root my device, but once I got the device I discovered for reasons regarding the chipset and where I live, enabling OEM Unlocking in the Developer settings was not an option.

Because of this, I wanted to check, if anyone on this forum knew if I bought the Samsung Tab S8 (regular wifi version, no cellular) in America from Amazon, would I be able to root the device with the Snapdragon 8 Gen 1 chipset?
[Samsung Galaxy Tab S8] patrickvu:
The OEM unlocking option did not return after 172 hours of uptime, 'KG State: Active' was still shown in download mode. So I returned it.
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
Well, I generally want to answer your question as "Yes, you'll be able to OEM Unlock it (and therefore unlock the bootloader)", however, coming from Amazon, I can't really vouch for that. If it is truly on a United States CSC (once you have the device, Go to settings - about - software information - service provider SW ver. The region code (CSC) will be written there), and it's Wi-Fi only, then yes, normally it's only United States Samsung tablets that can use mobile data (so made to use with a U.S. mobile carrier) that are prevented from being able to OEM unlock.

I ordered my Wi-Fi only, Snapdragon 8 Gen 1, United States Tab S8 Ultra directly from Samsung and have mine unlocked and rooted. My CSC is XAR. I did similar research on here as you are doing before I ordered mine.

As long as you are able to return it to Amazon for a refund if for some reason you can't unlock it (as you can return most everything on Amazon, but check the product's actual page to make sure), then you should be safe.
[Samsung Galaxy Tab S8] Chaser42:
I have the exact same SM-X700 from Amazon. I am also unlocked and rooted without any issues.

[Samsung Galaxy Tab S8] LightC:
Does anyone know if Samsung will accept rooted devices for trade-in? I want to root my s8 ultra but I want to be sure I can still trade it in at some point.
[Samsung Galaxy Tab S8] TricktPig:
I am not certain but I doubt they will accept it at the full trade-in price, especially considering root trips their KNOX fuse which cannot be reset by any means that we know of. I'd assume that means they need to replace the mainbaord or at the bare minimum that KNOX chip.
[Samsung Galaxy Tab S8] HARNATH:
Can you change the GPU and CPU frequencies now that you are rooted with a kernel manager?
[Samsung Galaxy Tab S8] HARNATH:
Did you find anything regarding this?
[Samsung Galaxy Tab S8] shadowofdeth:
Nope. Have all CPU cores running in performance mode but it still throttles far too quickly and aggressively. It feels better than stock values but not for long if you are even a little busy with some apps running. I've found an app called "Good Guardians" which lets you raise the throttling threshold a bit but it doesn't do anything as far as I can tell.

This tablet is a joke. First and last Samsung device. Should have known better.
[Samsung Galaxy Tab S8] Valiante:
No idea, I've been doing this for far too long to still be messing with petty things that squeeze out 0.39483% more performance from my device.
[Samsung Galaxy Tab S8] HARNATH:
It's not abt performance squeeze samsung gos or it's OS keeps capping my cpu and gpu frequency even though it's at 34-35 °C, previously disabling GOS fixed the problem but now even after disabling it's not getting fixed so I m searching for some method to lock my cpu and gpu frequency to a stable level and prevent throttling.

Example my poco f1 with SD845 can get stable 60 fps in games while this tablet struggles to maintain 45-50 fps how t* is this possible!!
[Samsung Galaxy Tab S8] HARNATH:
So this good guardian method will require rooting, seems I shd just use it for one year then sell it to get an ipad, rooting will break knox fuse and it's better to keep it's value up.

I was going to get an iPad but got tab s8+ as it seemed better and all reviewers were saying it's performance is good.

Now I am suffering with it's stupid reflective screen (display is great but too reflective and unusable outdoors) and bad performance.
[Samsung Galaxy Tab S8] shadowofdeth:
No root needed for the app. It's on the Samsung app store.

You will need root to change CPU governors and GPU clock speeds with a kernel manager. I'm using Elementalx. Doesn't help much though as throttling overrides everything. Seriously, last Samsung device for me. My phone runs so much better.
[Samsung Galaxy Tab S8] HARNATH:
If you use a GSI firmware will it overcome throttling issues since no OneUI anymore, or is throttling inbuilt even deeper? I read that S pen is also working in that but some special s pen feature are absent but they are rarely used.
[Samsung Galaxy Tab S8] shadowofdeth:
Throttles regardless. Qualcomm throttle the 8 gen 1 but then Samsung added their own throttling which kicks in way before it's even necessary. It's honestly a joke what Samsung have done here. If I'd have known I wouldn't have bothered.
[Samsung Galaxy Tab S8] Kenaz Rune:
Are there other non Samsung Android tablets that are more perfomant? I won't buy Chinese owned, so those are out.
[Samsung Galaxy Tab S8] shadowofdeth:
Don't know as my last tablet was the Nexus 7. Pretty sure this line is the "best" right now for tablets though. Chinese might be worth a look with some good research.

Shouldn't expect any less from Samsung. I won't be buying anything from them again.
[Samsung Galaxy Tab S8] lloydsw:
Public confession of an idiot: I didn't pay attention & flashed CSC instead of Home CSC when updating this morning. Guess what I'm doing now???
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
I did the same thing either the first or second month I updated mine after I rooted it. 🍩 Now I re-read the instructions each month and move the unneeded file(s) to another folder before I start flashing, or even before I re-root the new AP.

Another time my AP file got corrupted during one of the transfers and I had to factory reset after, so I try to remember to check hashes on the AP file before and after in each direction of transfer, plus I use 7-Zip to test the .tar archive, and view its contents before I flash it.
[Samsung Galaxy Tab S8] lloydsw:
That's a good idea - killing CSC. I had the guide up for a refresher, but between reading & doing I got distracted.
[Samsung Galaxy Tab S8] jsm36:
It worked very well on my SM-X906B EUX.

But Magisk was NOT pre-installed after rooting. (Step 4).

I downloaded the magisk.apk again, installed it and then I could opten it, open the settings and reboot the device.

I don't use Netflix, maybe I will test Step 5 later.

Thank you very much!
[Samsung Galaxy Tab S8] shadowofdeth:
Is it okay to factory reset and keep root? This is my first Samsung.

On my phones I can factory reset from settings/recovery and get root again just installing the Magisk manager app.

Same deal for my Tab S8+?
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
Should be, yes.
[Samsung Galaxy Tab S8] TENlll423:
I got the S8 ultra and i really like it... I also have a oneplus 9 9 pro rooted..

I really love rooting my devices especially since than i can debloat and do other things.

Well now I have debloated some unwanted stuff from this tablet using ADB & Fastboot for Android NDK on my OP 9Pro..

So now im thinking that rooting isnt really going to be all that...

What other cool stuff are you all doing with your s8 ultra after rooting?
[Samsung Galaxy Tab S8] jhill110:
I've found over the many years (note 4) with Samsung devices that ability to freeze apps with TiBu (debloatIng) is a huge +. I have gone to rooting for that reason almost alone. Plus now I have some apps that require root I can't do without.

Don't worry about trading in your device with Samsung after unlocking the bootloader just relock it and send it in. Been doing this since Tab s2 with no problem. I sent tab s7 back for the Tab s8 plus (had bootloader unlocked and rooted) and Samsung has never said a word... Makes me think they Easley have a way of fixing the knox blown efuse thing.

Anyway, I always root my tablets. Why would they make it possible (unlike their Snapdragon phones) to do so if they cared?

Just my 2 cents.
[Samsung Galaxy Tab S8] TENlll423:
Right on. Thats why i love my OP9Pro. It is easy as hell to root and still use everything as if it wasnt like widevine L1, Banking Apps ,google pay or Wallet. i like font manager, adaway and etc mods. SD Maid is my fav for freezing apps and keeping track of whats all running..

I am super new to samsung and I'm really diving in and wanting to learn about it...

so whats the issue with Knox after rooting?

My xbox one controller with this tab ultra is decent too.

i have So much fun with it at work when im waiting inbetween loads..Asphault 9, CODM, GRID Autosport, and Modern combat is fun...

Try those games you al w/ the controller, you might like it a lot as well....
[Samsung Galaxy Tab S8] roirraW "edor" ehT:
Once you unlock the bootloader of a Samsung device, it permanently trips their "Knox" e-fuse. There is no way to undo it. That makes it, so you can never use Samsung Pay and maybe some other Samsung-specific features. Also, if you return it under warranty, they can see that Knox was tripped and can potentially not honor the warranty, although there are laws against that, but that doesn't always stop them.
[Samsung Galaxy Tab S8] TENlll423:
Thanks for the info and yeah I've been reading up on it...

As of now I'm going to hold off on rooting this tablet.

With me being able to debloat using my OnePlus 9 pro w/ adb and fastboot NDK I'm good with that..

I just got rid of digital well-being which is great.

I hate that overly intrusive app... LOL...

also if there is any apps or services I shouldn't get rid of if any of y'ou all could let me know on a PM or on here I'd appreciate it..

I'm thinking about getting rid of that Bixby stuff but I'm going to read up on it more... Thanks

can confirm rooted and updated to oneUI 5.0 with the following steps from the OP (with data intact)

3: Root update:

-use Frija or something else to get the latest file according to your device and your CSC :

-patch the whole AP file with magisk

-use Odin to flash AP (the patched one), CP, BL and Home_CSC (using CSC will wipe)

-Press and hold Vol-down and Power let go of all buttons once the screen turn on.

-You have root, data kept and update
[Samsung Galaxy Tab S8] Dhimas97:
Hello, Sorry guys if this a repeated question.

I wanted to buy S8 Wifi version (that only I can afford). But I also very likely to have root on all my device. I read there's a e-fuse and Knox thing, I don't have any experience with Samsung before. So I doing this research,

1. After i unlocked the bootloader which is the first step to gain root, is the e-fuse will be broke ?

2. Which apps that will be not working? (I dex affected?)

3. Is any hardware related will be not working or degrading in quality ? Such as camera will be noisy (like Sony)

You guys are expert and might have more experience, please please tell me details about it . I didn't get satisfaction on Google search regarding my question.
[Samsung Galaxy Tab S8] googlephoneFKLenAsh:
1. Yes.

2. Knox, secure folder, samsung pass and some third party apps which not allowing unlocked bootloader unlock.

3. No.
[Samsung Galaxy Tab S8] ElsaReyes:
Yes hi, I just tried to follow this guide to root the new Android 13 update but it didn't work. When I tried to flash the magisk patched AP file with Odin it came up Failed. And then I would have to factory data reset my tablet to get the tablet working again.

Does this guide, or Magisk just not work for Android 13 yet?

Cause followed the guide awhile back to root android 12, and I did exactly what I did now, and it all worked fine.

Hope someone can help.

[Samsung Galaxy Tab S8] Oranath:
Trying to root but having no luck so far, does anyone have any other tips for getting the OEM Unlock option to show in developer settings? I've tried the date/time trick and tried factory resetting and then doing the date/time trick again, that's worked in the past but no luck here.

I have a tab s8 ultra bought direct from samsung UK if anyone has had any luck with one of those?
[Samsung Galaxy Tab S8] studyhuan:
Did you also turn off auto update system in developer settings ?

Another way I did is flash back whatever version shows OEM unlock.

Right now I don't not what people exactly got after rooting devices. I show waring message while booting because I rooted my s8+ 5g.
[Samsung Galaxy Tab S8] minochi91:
have you ever tried it? and is Samsung DeX still running well after root?
[Samsung Galaxy Tab S8] old_fart:
I watched this youtube video ( tricky part at eight minutes. ) and was able to acquire root first time. I am now looking for a stable recover so I can make nandroid backups like I did ~ seven years ago. A guys got to dream . . .

Is it possible to update to 13 & keep root using this guide?

Well I went to 13 first and rooted second. After you're rooted, come back and click my 'like' button . . . I have used this method three times. Got a ( relatively speaking ) old tab too and that works also.

Interesting. Usa tab has less hw to it but the sw is 1.156 mega bytes bigger. Wow, that's a lot of bloat !

( I got a 906N, very little bloat model because I want to use Google Maps in the car . . . band 41 )

After making a backup, I did the upgrade & root in one step. Thankfully, all went well.
[Samsung Galaxy Tab S8] grown_man:
hi guys and thanks for the guide. but unfortunately i have a weird problem after gettin root. i have no write permission on system folder. tried some apps but didnt work. did i miss somethin or we have to wait until its done
[Samsung Galaxy Tab S8] old_fart:
I went into one of my favorite file apps, Root Explorer and walked down to SYSTEM. When I got there I saw it was defaulted to r/o but the app just let me toggle it to r/w. So it's not locked at r/o. Hope this helps.
[Samsung Galaxy Tab S8] grown_man:
i cant change to rw, i think ive some owner etc issues but idk how to fix so its better from beginning

did u root via youtube video (boot.img->magisk->patchedboot.img->odin) that u posted on previous messages (im on android 13 too, so it seems i should follow ur steps :p )
[Samsung Galaxy Tab S8] old_fart:
yup, followed the youtube. That step at eight and a half minutes was a pain.

Thanks for the tip.
[Samsung Galaxy Tab S8] Planet Indigo:
It seems like the few people that are on android 13 with magisk root (and safety net?) have gone to 13 non rooted then rooted afterwards. I saw a couple people who now have issues on 13 that were rooted on 12 before and upgraded. This kind of makes me worried...

Is there anyone who was rooted on 12, followed the OP steps to upgrade to 13, and is now fine on 13, with zero issues and also still passing safety net?
[Samsung Galaxy Tab S8] Vinsang:
yes followed the update step and I'm on 13 rooted no issue
[Samsung Galaxy Tab S8] grown_man:
still i try to get r/w permission. i made some mistakes but i dont know what it is. just once i get it for temprorary but after google/samsung accounts ( or may be update somethings) i lost it again. im hopeless

so i can root but i cant get rw permission at all

and surely i wanna say i hate samsung because i cant use adb commands
[Samsung Galaxy Tab S8] jhill110:
Same here. On 13 rooted everything is dandy.
[Samsung Galaxy Tab S8] Planet Indigo:
Ok, thanks for replying, a couple followups if you wouldn't mind:

1) Do you guys have an S8, S8+ or S8 ultra?

2) Which CSC version are you on? XAR?

3) What version of Android 12 were you last on when you upgraded to 13?

4) Can you still pass Safety net and get widevine L1 while on android 13?

1)Ultra SM-X906B

This is probably a dumb question but here I go.

I have rooted Tab S8 Plus but I want to completely remove root and leave it as factory for my wife, she doesn't care about root at all and just want to use it normally and update it normally.

If I use Odin with the original Firmware would it work?

Sorry of this is not the place to ask.

Hello, I have a question related to the update process.

I rooted my Tab S8 and downloaded the latest firmware with Frija but I didn't get any CP-file. Do I need the CP-file or can I skip this option in Odin? And if I do, where can I get it? Why isn't Frija downloading it?
