SM-N975U Root: Is It Possible?

Updated 6 November 2026 · Standard formula, shown below

Yes, the SM-N975U (the U.S. carrier version of the Samsung Galaxy Note 10+) can be rooted, but it is significantly more difficult than rooting the international version (SM-N975F) due to the locked bootloader. This article explains what rooting this specific model entails, the risks, and the steps you need to take if you decide to proceed.

Background: Why the SM-N975U Is Different

The SM-N975U is the Snapdragon variant sold by U.S. carriers (AT&T, T-Mobile, Verizon, Sprint, etc.) and Canadian carriers. Unlike the Exynos-powered international model (SM-N975F), the Snapdragon version has a bootloader that is locked by default. Samsung does not provide an official bootloader unlock mechanism for U.S. carrier devices, which means you cannot simply run fastboot oem unlock like you would on a Pixel or OnePlus phone.

This lock is the primary reason why rooting the SM-N975U is not a straightforward process. The international Exynos model (SM-N975F) has an unlockable bootloader via Samsung’s developer settings, making it the preferred choice for enthusiasts who want to root or install custom ROMs. For the U.S. model, the only known path involves a paid service that exploits a vulnerability in the bootloader, and this method is not officially supported by Samsung.

How Rooting Works on the SM-N975U

To root any Android device, you typically need to unlock the bootloader, flash a custom recovery (like TWRP), and then install a root manager (like Magisk). On the SM-N975U, the locked bootloader prevents the first step. The community has found a workaround using a tool called SamFAIL (or similar paid services) that exploits a vulnerability in the bootloader to allow flashing a patched boot image without officially unlocking it.

The process generally involves:

Downloading the correct firmware for your exact model and carrier.
Using a Windows PC and Odin (Samsung’s flashing tool) to flash a modified bootloader and recovery.
Installing Magisk to gain root access.

However, this method is not publicly documented in a step-by-step guide because it relies on a paid service that provides the patched files. The service typically requires you to send your device’s unique identifiers (like the IMEI) and pay a fee to receive the necessary files. The exploit is not open-source, and the service providers change their methods as Samsung patches vulnerabilities.

Risks and Warnings Before You Root

Rooting any phone voids its warranty, but the SM-N975U has additional risks:

KNOX Tripping: Rooting permanently trips the e-fuse, which disables Samsung Pay, Secure Folder, Samsung Pass, and other KNOX-related features. This cannot be undone, even if you unroot later.
Bricking: If you flash the wrong file or interrupt the process, you can permanently brick your phone. The SM-N975U is particularly sensitive because the bootloader is not meant to be modified.
No OTA Updates: Once rooted, you will not receive official OTA updates. You will have to manually flash updates, which can be complex and may break root.
Security Risks: Rooting removes some of Android’s built-in security protections. Malicious apps can gain deeper access to your system if you grant them root permissions.
Banking Apps: Many banking and payment apps detect root and refuse to run. You may need to use Magisk’s MagiskHide (now called DenyList) to hide root, but this is not always effective.

How to Choose: Should You Root?

Rooting the SM-N975U is not for the faint of heart. If you are a power user who wants to:

Remove bloatware (carrier apps you cannot uninstall normally).
Install custom ROMs or kernels for better performance or battery life.
Use root-only apps like Titanium Backup or AdAway.
Modify system files or overclock the CPU.

…then rooting might be worth the risk. However, if you just want to customize your phone or get rid of ads, there are safer alternatives (see below).

If you decide to proceed, you must be prepared to lose all data (rooting typically requires a factory reset), and you must be comfortable with the possibility of bricking your device. It is also essential to use a reliable service and follow their instructions exactly. Many users have reported success with paid services, but there are also reports of bricks, so choose carefully.

Common Problems and How to Avoid Them

Users who attempt to root the SM-N975U often encounter the following issues:

Bootloop: If the phone gets stuck in a boot loop after flashing, you may need to reflash the stock firmware using Odin. This is a common fix, but it will erase your data.
Wi-Fi or Cellular Not Working: After rooting, some users report that Wi-Fi or cellular data stops working. This is usually due to a mismatched firmware or a corrupted modem partition. Reflashing the correct firmware usually resolves it.
SafetyNet Fails: If you use Google Pay or other apps that require SafetyNet, you will need to use Magisk’s DenyList to hide root. This is not always successful, and Google frequently updates SafetyNet to detect root.
Battery Drain: Some custom kernels or ROMs can cause excessive battery drain. If this happens, try a different kernel or revert to stock.

Alternatives to Rooting

If you want to customize your SM-N975U without the risks of rooting, consider these alternatives:

ADB Debloating: You can use ADB commands to disable carrier bloatware without root. This is safe and reversible.
Launchers and Icon Packs: Use a custom launcher like Nova Launcher to change the look and feel of your phone without root.
Good Lock: Samsung’s Good Lock app (available in the Galaxy Store) lets you customize the lock screen, notification panel, and more, without root.
Package Disabler Pro: This app (no longer on the Play Store, but available via APK) can disable packages without root, but it may not work on all firmware versions.
Custom ROMs (without root): Some custom ROMs, like LineageOS, can be installed on the SM-N975F (Exynos) but not on the SM-N975U due to the locked bootloader. If you are set on a custom ROM, consider buying the international version instead.

Costs and Services

Rooting the SM-N975U typically requires a paid service. Prices vary, but you can expect to pay anywhere from $20 to $50 for the patched files. These services are not officially affiliated with Samsung, and they operate in a legal gray area. They usually require you to provide your device’s IMEI and model number, and they may ask for a donation or payment via PayPal or cryptocurrency. Be wary of scams; only use services with a good reputation in the XDA forums or other trusted communities.

Safety and Legal Considerations

Rooting is not illegal, but it voids your warranty and may violate your carrier’s terms of service. In some countries, rooting may be considered a breach of copyright or consumer protection laws, but this is rare. The main safety concern is the risk of bricking your device. Always back up your data before attempting any modification, and ensure you have a way to restore your phone if something goes wrong (e.g., by downloading the stock firmware beforehand).

Frequently Asked Questions

Will rooting my SM-N975U trip KNOX?

Yes, rooting will trip the KNOX fuse, which permanently disables Samsung Pay, Secure Folder, Samsung Pass, and other KNOX features. This is irreversible, even if you unroot later.

Can I root my SM-N975U without a PC?

No, the current methods require a Windows PC and Odin to flash the necessary files. There is no one-click root app for this device.

Will I still get OTA updates after rooting?

No, you will not receive official OTA updates. You will need to manually flash updates, which can be complicated and may break root. Some custom ROMs offer their own updates, but these are not official.

Is it safe to use banking apps after rooting?

Most banking apps will detect root and refuse to run. You can try using Magisk’s DenyList to hide root, but this is not guaranteed to work, and some banks use more advanced detection methods.

What is the difference between SM-N975U and SM-N975F?

The SM-N975U is the Snapdragon version sold in the U.S. and Canada, while the SM-N975F is the Exynos version sold internationally. The main difference is the processor, and the bootloader is unlockable on the Exynos model, making it much easier to root.

Can I root my SM-N975U if I have a carrier lock?

Yes, the carrier lock (SIM lock) is separate from the bootloader lock. Rooting does not unlock the carrier lock, and vice versa. If your phone is carrier-locked, you will need to unlock it through your carrier before using it with another carrier, regardless of root status.
