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/S23+/S23Ultra


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?

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!

    So just rename .tar.md5 to .tar, extract the boot.img and feed that to Magisk? Then after, replace boot.img with patched boot.img in the .tar and rename it back to .tar.md5?

    I still love TBU, for the simple fact that i use it to freeze/delete apps on my phone that i dont want/need. Its great for that alone.
    Titanium works fine on S23U except it doesn't restore split apks. This needs to fix with apk itself. All other features still works fine. I am using SwiftBackup now since 2-3 years and my primary software to backup/restore still I prefer to have Titanium on my device.

    I use the app Service Disabler which is light and can do the same (freeze/delete). Root is needed. It keeps the disabled apps also after updating firmware.

    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
