How To Guide How to Root S23 (S91*B/N/0) - Samsung Galaxy S23 Ultra

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 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
Download and Install latest Magisk apk (Get Latest Magisk apk 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

Will try this now. Should the other slots BL/CP/CSC be filled with the firmware files when flashing this AP?

No needs, Flash requied file with AP slot onl

I flashed the AP file. I could not enter recovery mode to do factory reset. Device went into boot-loop mode, but after some failed attempts launched recovery by itself. Then I was able to do factory reset, and device boots properly.
Magisk (25.2 from apk in your zip file) still indicates: not installed. Ramdisk yes. Zygisk no (obviously).

Earlier today I used Magisk alpha to patch the AP from WA6 firmware.
Some minutes ago I flashed AP file from you on top. It only wrote boot and vbmeta.
Any debug info/logging I can provide?

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!

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?
