If I want to update my tab but without root and available ota and without losing existing data. Can I just follow step 3 ? What do I choose as AP ? What do I have to pay attention to ?

Thanks Guy's
If you want to update your tab without root, just use the regular Samsung provided over-the-air update.

If you don't want to root your device, you shouldn't be using SamFirm + Odin, etc. They add extra complexitiy that you don't need if you're not rooting your device.

Understood. But i debloated my Tab -> [NO-ROOT] Complete Samsung Galaxy Optimization Guide

and it was recommended to use Odin + Frija to Update instead of OTA cause OTA can break debloat/tweak changes etc.

It doesn't matter if it gets a lil more complicated.
Thanks for your help.

Anyone working on a Twrp or other custom recovery? I checked Samsung open source and it has the kernel source available for all of the models I put in. I did the S8 ultra, S8 plus and S8 wifi. I know custom recoveries aren't what they used to be for backing up and restoring but it's still better to have for uninstalling magisk modules that cause a bootloop. I know the bootloop fix magisk module I have it on my tab S6 and it doesn't always work.

Side note you guys should check to see if you can change selinux to permissive. I can on my Tab S6 and S10 lite both running android one ui 4.1. I'm hoping Samsung continues keeping the option for us who are no scared to death of someone stealing my information. If Google has your face unlock, fingerprint, your id and credit card number, all of your passwords and emails have you not already given everything to Google and Samsung? Lol uses fake name and email like I do. Gift cards for play store

The last I saw - but that was months ago - TWRP hasn't been made for any Android 12 device yet. If someone knows of an Android 12 device that has gotten TWRP, feel free to correct me. I have hardly missed it, so I don't stay on top of the news about it.

So if they still haven't, they need to work on getting it Android 12-compatible in general, and then they can start tackling individual Android 12 devices.

My Poco F3 is android 12 with orange fox and twrp available but it didn't come with Android 12. Twrp for Android 12 is unable to decrypt the internal storage however it doesn't matter if you decrypt the internal storage. I believe the the S22 ultra was working on it. But I don't really follow I just check when I'm bored because honestly every year we seem to lose more and more control even with root. So I worry that any year could be the last year we can root.

Has anyone tried to change selinux to permissive to check? You can literally instantly switch it right back to enforcing.

If you use termux
You type su hit enter and give root
Type setenforce 0 enter
To check type getenforce hit enter and it'll tell you enforcing or permissive.
Type setenforce 1 hit enter to change it back to enforcing.
If anyone tries it let me know I would appreciate it thanks.

Awesome now I wish I had the S8 tablet. How do you feel about it? I've heard the same thing I think of my tab S6. It's a great tablet except the cameras could be better.

Did you react to my post saying you tried permissive mode or because your wondering to?

To be honest, I haven't used it that much yet. My wife and I both like the idea of having it available, and we'll both possibly use it more when we go out of town for a few days. We both like the idea of having an Android tablet with one of Samsung's capable stylus to use when we need to. So far, besides my initial root and setup of it, most of my time on it has been just updating it once a month.

I'm just curious to know, and I liked your post just because it's a good question, but I don't think I'm motivated to try it.

Right on yes the Spen is great and ironically enough writing with it it's probably the least feature I use. I use it a lot to translate and select stuff like a mouse.

anyone rooted SM-X806B 5G ? I have enabled the OEM unlock, but I can never get the Unlock bootloader option from the download mode. I would wonder If it is because my Tab S8+ is LTE ?

It was explained to me that all the 5G versions of the Samsung tablets in the United States (if that's where you are) are not able to have their bootloader unlocked - no matter what carrier variant. If outside the United States, I don't know if the situation is different.

I'm surprised it even lets you enable OEM Unlocking.

has anyone tried to flash the WIFI rom on LTE version's tablet. As I'm aware most of samsung firmware of WIFI and LTE are compatible. Anyone has tried it to unlock bootloader with the WIFI firmware on LTE tablet ?

I presume an unlocked bootloader would be required to flash any firmware that's not meant for the device - as that's usually the case. I hope I'm wrong for your sake, though.

It's so hard now to follow this. A couple years ago I always did it on all my devices but the last 2 years I just can't do it anymore. Darn it. I so miss having a rooted device

    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.

    I have the exact same SM-X700 from Amazon. I am also unlocked and rooted without any issues.

    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.

    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???
    1
    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.
    That's a good idea - killing CSC. I had the guide up for a refresher, but between reading & doing I got distracted.

    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.

    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.

    How to Root (or update an already-rooted device)​

    Prereqs​

    1. Install the USB driver from https://developer.samsung.com/android-usb-driver
    2. Get the latest Odin from https://odindownloader.com/category/download and unzip it
    3. Get the latest Frija from https://github.com/SlackingVeteran/frija/releases and unzip it
    4. Start Frija and begin downloading the latest firmware for your Model and CSC:
      S8UltraRoot1.png
      1. Model Numbers
        • S8 Ultra 5G: SM-X906
        • S8 Ultra Wifi: SM-X900
        • S8+ 5G: SM-X806
        • S8+ Wifi: SM-X800
        • S8 5G: SM-X706
        • S8 Wifi: SM-X700
      2. CSC: Settings > About Tablet > Software Information > Service provider software version

    Step 1 - Prepare your Tablet (only necessary for first install on unrooted device)​

    1. While Frija is downloading the firmware, prepare your device by doing the following:
    2. Settings > About Tablet > Software Information > Click Build Number 7 times quickly
    3. Developer Options (just below About Tablet on the left column)
      • Turn on USB Debugging
      • Turn on OEM unlocking
        • NOTE: If the OEM Unlocking option doesn't appear, connect the device to the internet, wait a few minutes, then try again
    4. Power tablet completely off (Hold volume down + power button if you haven't changed the Bixby settings)
    5. While holding volume up and volume down, plug the tablet into your PC via USB
      • Let go of volume keys as soon as the blue-green screen shows up
    6. Press and hold volume up for 5 seconds, the screen will change to a confirmation prompt
    7. Press volume up again to confirm, the tablet will reboot
    8. Unplug your tablet from USB
    9. Go through initial setup. Don't bother copying files or installing anything.
    10. Skip signing in to your Google account and Samsung account. You won't be using them for this step.
    11. Settings > About Tablet > Software Information > Click Build Number 7 times quickly
    12. Developer Options (just below About Tablet on the left column)
      • Turn on USB Debugging
    13. Reboot the tablet

    Step 2 - Patch the stock firmware to make it rooted​

    1. Frija should have finished downloading by now, unzip the file (remember where you unzipped it to)
    2. Plug your tablet in to your computer via USB and click Allow if it prompts to allow data access
    3. If this is your first install / you're rooting the tablet for the first time:
      1. Download Magisk-vXX.XX.apk from the topmost release at https://github.com/topjohnwu/Magisk/releases
      2. Copy the Magisk-vXX.XX.apk and the AP_xxx_xxx_tar.md5 from the zip file Frija downloaded to:
        • This PC > Galaxy Tab S8 Ultra > Internal Storage > Download
      3. Open the My Files app on the tablet and browse to Downloads
      4. Click the Magisk-vXX.XX.apk and it will prompt you to click Settings
      5. In Settings, turn on My Files, then it will give you a prompt to Install
      6. When Magisk is done installing, click Open
    4. If your tablet was already rooted, and you're just updating:
      1. Copy the AP_xxx_xxx_tar.md5 from the zip file Frija downloaded to:
        • This PC > Galaxy Tab S8 Ultra > Internal Storage > Download
    5. After the file is done copying, unplug your tablet from USB
    6. In Magisk, click Install in the top Magisk area, then the option for Select and Patch a file
    7. Click My Files > Downloads, select the AP_XXX_XXX.tar.md5 file and click Done at the bottom
    8. Click Lets Go -> After a few moments, it should display this (ignore 'Installation failed' at the top, it always does that):
      S8UltraRoot2.png

    Step 3 - Apply the rooted firmware​

    1. Plug your tablet back in to USB, then on your PC, go back to This PC > Galaxy Tab S8 Ultra > Internal Storage > Download and copy the magisk_patched-xxx.tar file back to the folder where you unzipped the zip file from Frija
    2. After the copy is finished, unplug your tablet from your PC and turn the tablet off
    3. While holding volume up and volume down, plug the tablet into your PC via USB
      • Let go of volume keys as soon as the blue-green screen shows up
    4. Click volume up briefly (don't hold it) to go into download mode
    5. Start Odin and accept the disclaimer prompt.
    6. Click BL and select the BL_XXX_XXX.tar.md5 file where you unzipped the zip file from Frija
    7. Click AP and select the magisk_patched-XXX.tar file
    8. If this is your first install / you're rooting the tablet for the first time (this WILL wipe your data):
      • Click CSC and select the CSC_XXX_XXX.tar.md5
    9. If your tablet was already rooted, and you're just updating (this WILL NOT wipe your data):
      • Click CSC and select the HOME_CSC_XXX_XXX.tar.md5
    10. Odin should now look like this:
      S8UltraRoot3.png
    11. Click Start. When it's finished, Odin will display "PASS!" and the tablet will automatically reboot.

    Step 4 - Verify and finalize​

    1. Go through the normal setup, signing in to your Google and Samsung accounts this time
    2. Click on Magisk that is now pre-installed, and go through the Settings step to allow it to install again
    3. It should prompt you that your device needs additional setup and one more reboot, click OK
    4. After rebooting, your device should be fully rooted. Use a root checker app if you want to verify.

    Step 5 (optional) - Get Netflix (and banking apps etc) working with root​

    1. Install https://github.com/Fox2Code/FoxMagiskModuleManager/releases and run it
    2. Search for Universal Safetynet Fix by kdrag0n and install it
    3. In Magisk settings click Systemless hosts, turn on Zygisk, turn on Enforce Denylist
    4. Click Configure Denylist, then the 3 dot menu and Show System Apps
      1. Search for Google Play Store, click it, check the check and turn on all options underneath
      2. Search for Google Play Services, click it, turn on .gms and .gms.unstable ONLY
      3. Search for Netflix, click it, check the check and turn on all options underneath
      4. (optional) Add your bank / pay app, etc here if you'd like
    5. In Settings > Apps, search for Google Play Services and Google Play Store and clear all data (not just cache) for each
    6. Reboot
      1. NOTE - This is currently only passing Widevine level 3, so Netflix is limited to SD. I'm still trying to figure out how to get L1 / full HD.

    See post #3 for in depth guide !

    ->insert usual general disclaimer of liability

    Required:
    Odin3_v3.14.1 flash tool
    Samsung USB Driver installed
    Frija or something else, to download stock files
    7zip or similar

    1: Unlock bootloader (will wipe your precious data, void warranty, break Knox e-fuse and who knows what else !)
    -unlock dev option (just harass your Build number in settings)
    -be connected to the internet (WiFi or 5g)
    -allow USB debugging
    -OEM unlock
    -be warned that this might cause WWIII
    -Power off your device. Press Volume Up + Volume Down THEN plug your Tablet lnto a PC to boot into download mode.
    -Release buttons immediately when the blue screen shows itself.
    -Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot
    -Go through the initial setup.
    -Skip through all the steps except wifi or 5g
    -sign into your Google or Samsung account
    -Enable Developer options & USB debugging
    -reboot
    -You have an unlock bootloader and have control over your device, (it is unfair that this voids your warranty as you should be able to use your hardware as you please).


    2: Root install:
    -Install Magisk
    -use frija or something else to get the latest file according to your device and your CSC :
    -patch the whole AP file with magisk (transfer of big files can be tricky, using SD card to transfer file from computer to tablet and vice versa seems like one if the easiest way)
    -use odin to flash AP (the patched one), CP, BL and CSC (will wipe once again and reboot)
    -Open magisk to finish install (reboot)
    -You have root

    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


    Please let me know if something should be added or edited.

    Anyone work out how to get Netflix working with root yet? Also, is Magisk manager showing any modules to download in the Magisk app for you guys? I can install from file, but the downloading functionality doesn't seem to be working.
    Not sure when, but somewhere in an update, the ability to download modules from magisk directly was removed. You can download them using an app called Fox's Magisk Module Manager. You can search for modules just like you could on Magisk, and they'll be added once you install them and reboot. Also, for the netflix thing, your device may not be passing safetynet. Checking this was also remove in an update, but you can check it with YASNAC.

    Edit: I just did this with my rooted Tab S7+, but it should work with the S8+ and S8U as well. Doing this should let you pass safetynet and be able to use Netflix.
    1. Enable Zygisk in Magisk settings, then reboot.
    2. Enable Enforce DenyList in Magisk settings, then go to Configure DenyList.
    3. Enable show system apps with the menu on the top-right, then search "google play services".
    4. Enable DenyList for com.google.android.gms & com.google.android.gms.unstable, then reboot.
    5. Open YASNAC to run safetynet attestation, you should be passing basic integrity but failing cts profile match.
    6. Download and install the latest version of the safetynet fix for zygisk module, then reboot.
    7. Check YASNAC again, you should now be passing basic integrity and cts profile match.
    8. Go to settings > apps, find google play service & google play store, clear data for both of them, reboot.
    9. Go to the play store > settings, play protect certification should now say "device is certified".
    10. Open Magisk > Configure DenyList, search for Netflix (enable show system apps if you need to), enable DenyList for everything, reboot.
    11. Update Netflix if it's not up to date. If the play store is allowing you to update Netflix at all, then you're good to go.

    Now you have Netflix running on your rooted tab!

    Edit 2: Accidentally saved my first edit before I finished the instructions, my bad.

    If I want to update my tab but without root and available ota and without losing existing data. Can I just follow step 3 ? What do I choose as AP ? What do I have to pay attention to ?

    Thanks Guy's
    If you want to update your tab without root, just use the regular Samsung provided over-the-air update.

    If you don't want to root your device, you shouldn't be using SamFirm + Odin, etc. They add extra complexitiy that you don't need if you're not rooting your device.

    Is there currently any way to make nandroid backups without TWRP since there isn't a build of it for the Tab S8 line yet?
    Not you can't make a full nandroid back up without TWRP for the moment. You can use Swift backup or something similar to backup some things in particular, Google backup is also pretty convenient.
