Root Note 3 on Lollipop? What You Need to Know

Yes, you can root a Samsung Galaxy Note 3 running Android 5.0 Lollipop, but the exact method depends on your device model and the specific Lollipop build you have installed. This article explains the main rooting options, their risks, and how to choose the right one for your Note 3.

Why Rooting a Note 3 on Lollipop Is Different

The Galaxy Note 3 shipped with Android 4.3 Jelly Bean and later received official updates to 4.4 KitKat and 5.0 Lollipop. Samsung’s Lollipop update introduced a stricter security patch (often referred to as the “Knox� warranty bit) and a new bootloader on some models. This means that methods that worked on KitKat—like using an older version of Odin to flash a pre-rooted image—may not work on Lollipop, and the risk of tripping Knox (which voids your warranty and permanently disables some Samsung features) is higher.

Additionally, the Note 3 has many regional variants (e.g., SM-N9005, SM-N900T, SM-N900W8, SM-N900P), and each has its own bootloader and modem. The rooting tool you use must match your exact model and firmware version.

Common Rooting Methods for Note 3 on Lollipop

There are three main approaches, and the right one depends on your model and whether you want to keep your data intact.

• CF-Auto-Root (Odin): A one-click script that flashes a patched kernel and SuperSU via Odin. It works on many Note 3 models, but you must use the correct version for your device. It does not wipe data, but it does trip Knox.
• Custom recovery (TWRP) + SuperSU: First flash a custom recovery (like TWRP) via Odin, then boot into recovery and flash a SuperSU ZIP. This is more flexible and also allows you to install custom ROMs later.
• Pre-rooted firmware: Some developers repackage the official Lollipop ROM with root already included. You flash it via Odin, and it usually wipes your phone. This is the most reliable if you have a locked bootloader, but it’s model-specific.

How to Check Your Note 3 Model and Bootloader

Before you do anything, you need to know your exact model number and current software version. Go to Settings → About Device and note the “Model number� and “Baseband version�. The model number is the most important part—it tells you which root package to download. You also need to know your Android security patch level, because some later Lollipop builds (e.g., 5.0.1 with a newer patch) may block older exploits.

If you have a carrier-locked device (e.g., Verizon, AT&T), the bootloader is often locked, which means you cannot flash custom recoveries or kernels. In that case, your only option is a pre-rooted firmware that uses a bootloader exploit—if one exists for your exact build. If you have an international or T-Mobile model, the bootloader is usually unlockable, so you have more flexibility.

Step-by-Step: Rooting with CF-Auto-Root (Most Common)

This method works for many Exynos and Snapdragon Note 3 models on Lollipop.

1. Download the correct CF-Auto-Root package for your exact model (e.g., CF-Auto-Root-hlte-hltexx-smn9005.zip for the international N9005).
2. Extract the ZIP to get a .tar.md5 file.
3. Install Samsung USB drivers on your PC and enable USB debugging on the phone (Settings → Developer Options).
4. Power off the phone. Boot into Download Mode by holding Volume Down + Home + Power simultaneously, then press Volume Up to confirm.
5. Open Odin (a Windows tool) as Administrator, connect the phone, and wait for the ID:COM box to turn blue.
6. Click the AP (or PDA) button and select the .tar.md5 file. Do not change any other options.
7. Click Start. The phone will reboot automatically. When it boots, you should see the SuperSU app in your app drawer.

If Odin fails or the phone gets stuck on the boot logo, you may need to repeat the process or try a different method. Always back up your data before attempting, because even if the process says “no wipe�, a failed flash can leave you in a bootloop.

What If You Have a Locked Bootloader? (Verizon, AT&T, etc.)

Carrier-locked Note 3 models (like the Verizon SM-N900V or AT&T SM-N900A) have locked bootloaders that prevent flashing custom recoveries or kernels. For these, the only viable root method is a pre-rooted firmware that exploits a vulnerability in the bootloader itself. These are rare and often only available for specific firmware versions. You will need to search XDA-Developers for your exact model and build number. If no exploit exists for your current build, you may be stuck—downgrading to an older firmware may not be possible because Samsung blocks downgrades with a bootloader counter.

If you have a locked bootloader, the safest approach is to check the XDA forum for your device and see if a root method exists for your exact baseband. Do not try to flash a custom recovery—it will fail or brick your device.

Risks and What You Lose by Rooting

Rooting your Note 3 on Lollipop carries several risks:

• Knox tripped: The Knox warranty bit will be set to 0x1, permanently voiding your Samsung warranty and disabling KNOX features (like Samsung Pay, Secure Folder).
• Potential brick: A wrong flash or interrupted process can soft-brick (bootloop) or hard-brick (no power) your phone. Hard bricks are often unrecoverable without a JTAG service.
• Security: Rooting removes some Android security sandboxing, so malicious apps can read more data. Be careful with what you install.
• OTA updates: Once rooted, you won’t receive official over-the-air updates. You’ll need to manually flash updates or switch to a custom ROM.

After Rooting: What’s Next?

Once you have root, you can install SuperSU (or Magisk if you used a custom recovery) and grant root access to apps. The most common uses are:

• Removing bloatware (system apps you don’t use).
• Using ad-blockers that require root (like AdAway).
• Installing a custom kernel for better battery life or performance.
• Flashing a custom ROM (like LineageOS) to get a newer Android version—though the Note 3 is old, and most custom ROMs are unofficial.

Frequently Asked Questions

Will rooting my Note 3 on Lollipop wipe my data?

CF-Auto-Root does not wipe data, but it’s always recommended to back up before any firmware flash. Custom recoveries and pre-rooted firmware may wipe data, so read the instructions carefully.

Can I unroot later?

Yes, you can unroot by flashing the stock firmware via Odin. However, the Knox bit will remain tripped (0x1), so you cannot restore your warranty. If you used Magisk, you can also unroot via the Magisk app.

What is the best root method for the international N9005?

CF-Auto-Root is the simplest and most reliable for the N9005 on Lollipop. It’s a one-click process and doesn’t wipe data. If you want to install custom ROMs later, use TWRP + SuperSU instead.

Why does my phone show “Custom binary blocked by Reactivation Lock�?

This happens when Reactivation Lock is enabled in Settings → Security. It prevents flashing custom binaries. Turn it off before rooting. If you see this error, boot into Download Mode, and Odin will still work if you disable the lock.

Can I root without a PC?

Some apps like KingRoot claim to root without a PC, but they are unreliable and often contain malware. For the Note 3 on Lollipop, a PC-based method is strongly recommended.

Is there any way to root without tripping Knox?

No. Any method that modifies the kernel or bootloader will trip Knox. There is no way to root a Note 3 on Lollipop without tripping it, unless you use a systemless root (like Magisk) on a custom kernel that doesn’t trip it—but that still requires an unlocked bootloader, which is rare on Note 3.
