Rooting method

Step 1. Download the full Odin firmware package for your exact model and CSC region (Odin 4-File Firmware).
Step 2. Copy AP_*.tar.md5 to the phone and open the Magisk app. Tap Install → Select and Patch a File and choose the AP tar. Magisk patches boot.img inside it — no manual extraction is required.
Step 3. Copy the resulting magisk_patched.tar back to your computer.
Step 4. Open Odin and load magisk_patched.tar in the AP slot, then load the matching BL, CP and HOME_CSC files from the same firmware package.
Step 5. Flash, then boot the device and open the Magisk app to confirm root.

Flash command

Odin3: AP = magisk_patched.tar | BL + CP + HOME_CSC from the same firmware

For the full workflow and prerequisites, see the installation guide and boot image patching guide.

Keeping root across updates

Download the full Odin firmware for the new build, patch the new AP tar in the Magisk app, then flash it together with BL, CP and HOME_CSC (HOME_CSC keeps your data).

See the OTA survival guide for the full procedure.
