The options we have with root apps these days are giving people oodles more reasons to follow one of these guides to find out how to root the Samsung Galaxy Note 3 smartphones. Apps have and are always going to be one of the primary reasons as to why you should root the Android operating system on your Galaxy Note 3 to go along with your installing aftermarket firmware.
ROMs are fun because they come with many new features and offer people new software that is more tailored to meet their needs instead of a general audience like the stock Android operating system. We have seen many root apps that almost mimic the effects of what installing a custom ROM can do — the Xposed Framework being toward the top of that list, but there are also many more apps out there that can change and tweak your operating system like the Tasker application.
Visuals and features are always impressive, but they are not the only reasons to root the Samsung Galaxy Note 3. Some people will always find a way to get up to no good and try installing some illegal apps that allow them to download free upgrades to apps and so forth, but the vast majority of people out there can make use of rooting doing nothing illegal at all. Should you own a device that you have paid for in full, there is no reason why you cannot tweak the internal system if you are an advanced Android user. Tweaking the system’s hard to know where the boundaries are which is why it is only to be done by an experienced Android user — and that does not mean you who bought the Android phone two months ago and now are calling yourself an experienced Android user. It means people who know their hardware right down to the digits and exactly what those components can do and do. That is the only way you can successfully overclock and underclock the Android operating system with the hardware in your smartphone without creating problems. Nevertheless, that option is there if you think you have the ability to give it a go without bricking the phone. Those who can underclock and overclock the OS successfully can enjoy internal hardware that is clocked to suit their needs and not the way it comes out of the box. You can underclock the Samsung Galaxy Note 3 smartphone to get better battery performance or overclock to increase the hardware performance for your gaming and so forth.
The rooting exploit in this guide is based on LRX21V.N9002ZNUGPA1 firmware which is part of an Android 5.0 Lollipop rollout in some regions. You do not need to find out which areas exactly that firmware build number arrived for because you do not need it running on your Samsung Galaxy Note 3 smartphone before you start with the guide. The guide will work for the SM-N9002 model number running any version of Android 5.0 Lollipop regardless of the firmware build number. Chainfire gives the build number he used so you can see it and use it as an indicator.
What Is Rooting the Android Operating System?
When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.
Why Would You Want to Root Android?
Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:
- Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
- Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
- Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
- Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.
What Are the Risks of Rooting?
If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.
With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:
- Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
- You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
- You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.
Files You Need
- Download the new CF-Auto-Root tool for the Samsung Galaxy Note 3 SM-N9002 on Android 5.0 from here.

The rooting exploit in this guide is for the Snapdragon 800 MSM8974 processor. Be careful of that because there are two versions of the Samsung Galaxy Note 3 with the SM-N9002 model number and only one of them comes with the Snapdragon 800 MSM8974 processor. Flash this file on the other version and it will be bricked.
Note that you must use a computer that is running a version of Windows operating system to use this guide. Likewise, you must only follow this guide with the SM-N9002 model number version of the Samsung Galaxy Note 3 that has the processor details listed above.
The Samsung Galaxy Note 3 could be subject to software updates in the future that bring new bootloaders with them. Only occasional updates bring new bootloaders with them, but when they do they can cause Chainfire to have to update his files on his end. Once Chainfire updates the files, those changes are always automatically reflected in our guides, so you will always have the latest version available when viewing out tutorials. However, before the files can be updated, Chainfires relies on you guys to submit the new recovery images to the official CF-Auto-Root thread over at the XDA-Developers website. He will see the message you leave and then he will fix the issue.
Rooting the Samsung Galaxy Note 3 SM-N9002 smartphone running on the Android 5.0 Lollipop updates
- Unlock the Developer Options menu on your Android operating system that is running on the Samsung Galaxy Note 3 smartphone.
- Enable the USB Debugging Mode on the Samsung Galaxy Note 3 smartphone so it can be connected to the computer.
- Extract the rooting package on the desktop of the computer so you can see the Odin flashing app and the CF-Auto-Root rooting file on the desktop.
- Run the Samsung USB Drivers on the desktop computer you are using in the guide so your device can be attached and detected by the apps on the computer.
- Press the Power button on the Note 3 smartphone and choose to turn it off completely from the menu.
- Hold the hardware button combination that will boot up the Samsung Galaxy Note 3 into the download mode.
- Connect your Note 3 phone to the computer with the USB cable that you normally use to charge the battery.
- Give it a few seconds and then check the Odin user interface provides you with a yellow or blue color which is letting you know that your drivers are working.
- Do not change any of the default settings from the Odin user interface before you proceed or else things might not go well.
- Click Odin’s AP button from the Odin user interface and then browse the desktop location for the rooting file that you extracted earlier already and then upload it to this place so you can see the file extension from the Odin user interface next to the AP button.
- Click Odin’s Start button from the Odin user interface and then wait until it is rooted.
- Look at the screen on the Galaxy Note 3 and wait for the text to roll down the display and show you that it is installing the SuperSU, cleaning up the cache partition and the flashing the stock recovery again.
- Check the Odin user interface on the computer for a green box that should light up with a pass message inside letting you know that it all went to plan.
In conclusion, that is how to root the Samsung Galaxy Note 3 smartphone with the SM-N9002 model number running on the Android 5.0 Lollipop updates. The smartphone will automatically reboot thanks to the way in which the developer, Chainfire has programmed the CF-Auto-Root package. As soon as it does, you will have the SuperSU application available from the app drawer. That is the app that is going to give you pop-up a message each time you install an app, and it needs the rooting permissions to run. Say yes to any messages from apps you did install and trust and said no to any apps you do not trust or that you do not recall installing. Just install the root checker app from the Google Play Store and open it up to check if your Samsung Galaxy Note 3 smartphone is rooted or not.
There are a couple of things you can try if you followed the guide above and your Samsung Galaxy Note 3 smartphone is still not rooted. Sometimes a smartphone or tablet will not get into the recovery mode automatically during the flashing and as a result, the device will not be rooted. Chainfire says that every device will need to get into the recovery mode at the end for the rooting to have worked. You can always solve this problem by pressing the hardware key combination for the recovery mode once your device does get rooted and it should fix the problem just the same.
Furthermore, there are several versions of the Odin flashing application that is available to install on the computer if you need to try something else. We have seen people report the device will not get rooted using one version of Odin, but it did get rooted when using another version. The versions are numbered so you can easily see when you are using different versions of the app. Chainfire gives the latest versions of the flashing tool bundled in with the rooting package, but that version will not always work one hundred percent of the time.
