How to Root Samsung Galaxy with Magisk & Odin

Understanding the Knox Warranty Void (0x1) Hardware e-Fuse

Samsung smartphones contain a physical, hardware-based One-Time Programmable (OTP) electronic fuse called the Knox e-fuse. When you unlock the bootloader and flash custom or patched binaries, this fuse is physically blown:

Step-by-Step Installation Walkthrough: Odin AP Flashing

Step 1: Unlock the Samsung Bootloader

1. Open Settings -> About Phone -> Software Information and tap Build Number 7 times to unlock Developer Options.
2. Open Settings -> Developer Options and toggle on OEM Unlocking and USB Debugging.
3. Power off your device completely.
4. Hold down both Volume Up + Volume Down buttons simultaneously and connect your phone to your PC via a USB cable.
5. The teal Warning screen will appear. Long-press Volume Up to unlock the bootloader.
6. Confirm the unlock. Note: This will perform a complete factory wipe of all user data! Allow the phone to boot up and complete basic initial setup without adding Google accounts.

Step 2: Download Stock Samsung Firmware

Download the exact official 4-file or 5-file Samsung firmware corresponding to your phone model and CSC region using open-source tools like Frija or SamFirm. Unzip the downloaded firmware archive to reveal:

• BL_*.tar.md5 (Bootloader)
• AP_*.tar.md5 (System, Boot, Recovery, Vbmeta - Transfer this file to your phone!)
• CP_*.tar.md5 (Modem/Baseband)
• CSC_*.tar.md5 (Region formatting & Clean wipe)

Step 3: Patch the AP File in Magisk App

1. Install the official Magisk APK on your Samsung device.
2. Copy the AP_*.tar.md5 file from your computer into your phone's /sdcard/Download/ folder.
3. Open Magisk, tap Install on the Magisk card, select Select and Patch a File, and choose the AP file.
4. Magisk will extract boot.img.lz4, init_boot.img.lz4, and recovery.img.lz4, inject magiskinit, disable verity flags in vbmeta, and repack the archive into:
   /sdcard/Download/magisk_patched_[random].tar
5. Transfer the magisk_patched.tar file back to your computer.

Step 4: Flash in Samsung Odin v3.14+

1. Reboot your Samsung phone into Download Mode (Power off -> Hold Vol Up + Vol Down -> Plug in USB -> Press Vol Up once).
2. Open Odin v3.14.4 on your PC. Verify that the ID:COM box lights up blue/teal.
3. Slot the files into Odin:
   • Click BL and select your stock BL_*.tar.md5.
   • Click AP and select your magisk_patched.tar file.
   • Click CP and select your stock CP_*.tar.md5.
   • Click CSC and select your stock CSC_*.tar.md5 (do NOT use HOME_CSC for initial root).
4. CRITICAL STEP: In Odin, click the Options tab and UNCHECK "Auto Reboot".
5. Click Start. Wait 3–5 minutes until Odin displays a green PASS! message in the top left.

Step 5: The Critical Recovery Reboot & Wipe

Because Auto Reboot was disabled, your phone remains in Download Mode. Follow this timing strictly:

Step 6: Complete Magisk Setup

Once Android boots up, connect to Wi-Fi. You will see a stub Magisk icon in your app drawer. Tap it to download the full app, or install Magisk-v30.7.apk via ADB. Open Magisk and tap OK when prompted to complete the environment setup. The phone will reboot once more and you will have 100% working Magisk root!
