How to Root Galaxy Note: Step-by-Step Guide

Card No. 06·8424 · Updated · Standard formula, shown below

Rooting your Galaxy Note gives you full administrative control over the Android operating system, allowing you to remove bloatware, install custom ROMs, overclock the CPU, and use apps that require superuser permissions. This guide walks you through the entire process—from unlocking the bootloader to verifying root access—using a Windows PC. Before starting, back up all important data, as rooting will wipe your device and void your warranty.

What You’ll Need

  • A Galaxy Note device (model-specific files required)
  • A Windows PC (or a Mac/Linux with Odin alternatives)
  • USB data cable
  • Odin flashing tool (download the latest version)
  • OEM unlock file (specific to your device model and Android version)
  • Magisk APK (for rooting after bootloader unlock)
  • Backup of your personal data (photos, contacts, etc.)

Step-by-Step

  1. Enable Developer Options: Go to Settings > About Phone and tap Build Number seven times. You’ll see a message that Developer Options are enabled.
  2. Enable OEM Unlocking: In Settings > Developer Options, toggle OEM unlocking to ON. If this option is greyed out, you may need to insert a SIM card and connect to the internet for a few days.
  3. Back Up Everything: Use Samsung Smart Switch or a cloud service to back up your data. Unlocking the bootloader will erase all data.
  4. Download Required Files: On your PC, download the latest Odin, the OEM unlock file (often a .tar or .tar.md5), and the Magisk APK. Ensure you get files specifically for your exact Galaxy Note model (e.g., SM-N950F for Note 8).
  5. Install Samsung USB Drivers: Install the official Samsung USB drivers on your PC so Odin can recognize your device.
  6. Boot into Download Mode: Power off your phone. Press and hold Volume Down + Home + Power (for older models) or Volume Down + Bixby + Power (for newer models) until the warning screen appears. Press Volume Up to continue.
  7. Open Odin as Administrator: Right-click Odin and select Run as administrator. Connect your phone via USB. Odin should show an “Added!� message in the log box.
  8. Flash the OEM Unlock File: In Odin, click the AP button and select the OEM unlock file you downloaded. Ensure F. Reset Time and Auto Reboot are checked. Click Start. The phone will reboot automatically when done.
  9. Set Up Your Phone: After the reboot, go through the initial setup. The bootloader is now unlocked, but the phone is not rooted yet.
  10. Re-enable Developer Options and USB Debugging: Go back to Developer Options and enable USB Debugging.
  11. Install Magisk: Transfer the Magisk APK to your phone and install it. Open Magisk and select Install > Install to Inactive Slot (if prompted). This will patch the boot image.
  12. Reboot and Verify: After Magisk finishes, reboot your phone. You should see the Magisk app in your app drawer. Open it—if it shows “Magisk is installed� and “Requires additional setup� is not present, root is successful.

Common Mistakes

  • Using wrong files: Flashing a file meant for a different model or Android version can brick your device. Always double-check model numbers and build numbers.
  • Skipping OEM unlock: If you don’t enable OEM unlocking before flashing, Odin may fail or the bootloader will remain locked.
  • Not backing up: Unlocking the bootloader wipes your data. Forgetting to back up means losing everything.
  • Interrupting the flash: Unplugging the USB cable or closing Odin during flashing can cause a soft brick.
  • Using a USB hub: A faulty connection can cause the flash to fail. Use a direct USB port on your PC.

Tips

  • Keep your phone charged above 50% before starting.
  • Use the original Samsung USB cable if possible.
  • Research your exact model on XDA Developers forums for model-specific guides and files.
  • After rooting, install a root manager like Magisk to control which apps get superuser access.
  • Consider installing a custom recovery (like TWRP) after rooting for easier backups and custom ROM installation.

Troubleshooting

Odin fails with “FAIL� or “SHA256 is invalid�: This usually means the file is corrupt or for a different device. Re-download the correct file and try again. If the error persists, try a different USB port or cable.

Phone stuck in boot loop: If your phone keeps restarting, boot into Recovery Mode (Volume Up + Home + Power) and perform a factory reset. If that doesn’t work, re-flash the original stock firmware using Odin.

Magisk shows “Requires additional setup�: Open Magisk and tap Install > Install to Inactive Slot (if available). If that fails, reboot to recovery and flash the Magisk APK manually.

Odin doesn’t recognize the phone: Reinstall Samsung USB drivers, try a different USB port, and ensure the phone is in Download Mode. Also, try running Odin as administrator.

Phone boots but no Magisk app: This can happen if the boot image wasn’t patched correctly. Re-download Magisk, uninstall the app, and repeat the installation process.

Frequently Asked Questions

Will rooting void my warranty?

Yes, rooting typically voids the manufacturer warranty. However, you can often restore the warranty by flashing the original stock firmware with Odin (unrooting).

Can I still receive OTA updates after rooting?

Usually not. OTA updates require a stock boot image. With Magisk, you can sometimes install updates manually by flashing the OTA file through Magisk, but it’s not guaranteed.

Is rooting safe?

Rooting itself is safe if you follow instructions carefully. The risk comes from using incorrect files or flashing incompatible mods, which can brick your device.

Will rooting improve battery life?

Not automatically. Rooting gives you the ability to use apps like Greenify or custom kernels that can improve battery life, but it can also cause worse battery if you install aggressive mods.

Can I unroot my Galaxy Note?

Yes. The easiest way is to flash the stock firmware using Odin. This will also relock the bootloader if you choose to, but note that it will wipe your data.

Do I need a PC to root?

Yes, most methods require a PC to flash files via Odin. Some devices can be rooted via apps like KingRoot, but these are unreliable and not recommended for Samsung devices.
