I'm waiting for my s23 ultra next week and then I'll be able to test.
I'm aware I'll lost Samsung Pay and pass. I really don't care... Don't use it... But, will I have troubles with Google pay and secure folder if rooted?

Some features can be restored with my LSPosed module (more info here)

Google pay and secure folder should work with patch. I will get device after 2 wk in my country so can't confirm myself currently

I am following this thread. Any way to flash the "B" firmware on a "U" model and then root with this method?

It works, i juste have an annoying message : Access denied (unauthorized changes have been made to your phone...) but that since i tried to root my phone the first time. Do you want me to do any tests ?
Run this command from terminal to fix annoying msg

Code:
su
pm hide com.samsung.android.dkey

Alternatively
In settings - app - enable system app and search Digital Key
And
Disable appear on top permission for digital key

No, you can't flash S918B firmware on S918U
Will this likely ever work on S918U variants?

Edit: I got excited and posted here without reading through other threads. Op 8 pro user here. Sick of mediocre specs on new OP phones, looking to switch to a real flagship but want root. Will keep monitoring this thread. Keep up the excellent work.

No, U version mostly unrootable. You won't find option to unlock bootloader.

UK so I guess Sm-S916B unless I'm wrong.

Was hoping it'd just be a straightforward root procedure like normal. Path ap in magisk and then flash along with bl and home csc as per normal.
Even you are not sure about your model number and seeking support for root?
This thread is about R&D and early root access, better you wait for convenient method till magisk officially add support for your device

    OP updated for How to Root S23 (SM-S91**) (except devices that doesn't support unlocking bootloader like S91*U)

    Also no more pre patched files will be provided so moving this thread to "How to Guide" section.

    in most apps, usually you can choose to toggle on/off for each notification category, but not in the System UI app
    you can't toggle them off because the components are disabled (only Screenshot can be toggled off/on as you wish)
    thanks
    That's same since oneui 5.0
    It requires patching core app, instead easiest way is to install NCleaner from play store, remove all unwanted notifications and then Uninstall NCleaner

    What is the background?
    Could the use of a stock AP tar file lead to a brick or would there just be no root available?
    If on rooted device, It will remove root. Just needs to factory reset after stock AP.

    Hello ,
    I'm sorry, but I don't understand when you tell us to download Magisk and install it. There are 2 files : release and debug. How do we do it ? one first and the other one later ? Thank you for your answer.
    You can use any one

    Would anyone know how to update rom and retain root? TIA
    Already mentioned in OP under "Upgrading the OS"

    How to Root Samsung S23 (SM-S91*B/N/0)



    WARNING!


    Before you root your device you must be aware that

    • This will void warranty.
    • As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
    • There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but some ROMs are patched for all these mentioned features, you can use custom ROM or patch it yourself for stock ROM. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
    • There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
    • Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
    • Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
    • OTA won't work once you root device.
    • ROOT with caution.
    • You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.

    How to Unlock Bootloader

    Follow below four steps to ulock the bootloader

    1.Enable Developer Option
    • Open the Settings app on your Galaxy device.

    • Now Developer option has been enabled.
    2: Enable OEM Unlock

    • Navigate to the Developer option.
    • Enable the toggle next to OEM Unlocking.
    • Tap YES to turn on the confirmation dialog box.

    Now you have successfully unlocked the bootloader


    How to root S23


    Instructions for stock non rooted ROM​

    • Use either samfirm.js, Frija, or Samloader to download the latest firmware zip of your device directly from Samsung servers.
    • Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
    • Install Magisk apk ( IMPORTANT : Currently stable Magisk doesn't support S23 so use from here)
    • Press the Install button in the Magisk card
    • Choose “Select and Patch a File” in method, and select the AP tar file
    • When done, copy patched file to PC
    • Reboot to download mode. Open Odin on your PC, and flash magisk_patched.tar as AP, together with BL, CP, and CSC (NOT HOME_CSC because we want to wipe data) from the original firmware.
    • Your device should reboot automatically once Odin finished flashing. Agree to do a factory reset if asked.
    • Install the Magisk app you’ve already downloaded above and launch the app. It should show a dialog asking for additional setup.
    • Let the app do its job and automatically reboot the device. Voila!

    Upgrading the OS​

    Once you have rooted your Samsung device, you can no longer upgrade your Android OS through OTA. To upgrade your device’s OS, you have to manually download the new firmware zip file and go through the same AP patching process written in the previous section. The only difference here is in the Odin flashing step: do NOT use the CSC tar, but instead use the HOME_CSC tar as we are performing an upgrade, not the initial install.

    Important Notes​

    • Never, ever try to restore either boot, recovery, or vbmeta partitions back to stock! You can brick your device by doing so, and the only way to recover from this is to do a full Odin restore with data wipe.
    • To upgrade your device with a new firmware, NEVER directly use the stock AP tar file with reasons mentioned above. Always patch AP in the Magisk app and use that instead.
    • Never just flash only AP, or else Odin may shrink your /data filesystem size. Flash AP + BL + CP + HOME_CSC when upgrading.

    PS : It is strongly recommended to make EFS backup once you root device and save to safer place like on cloud or PC

    For those interested I've made a pull request that has been approved (not pushed to the master branch tho) to add support for Samsung devices that shipped/will ship with Android 13 (like the S23 family) in the Magisk repository (https://github.com/topjohnwu/Magisk/pull/6586). You can find a test apk in the attachments to test yourself whether or not you can now patch stock firmware tar packages to install Magisk.

    Glad to share, Internal testing for TWRP started now!
    Big thanks to @afaneh92

    TWRP seems working fine with Test version of DrKetanROM

    This one gave me the "Magisk needs additional setup" prompt. After accepting + reboot, Manager detects magisk correctly and root is functional. Great work!
    Would you be able to upload a release kernel too? Thanks so much!
