There are many reasons as to why people root the Android operating system, and some of those reasons can come with a paradox or two. Ask people why they root Android and they might tell you to remove system apps to increase the performance. Ask another person and they might say so they can install more apps. It is true that apps — whether you want to delete or install more — play a major role in why people root the Android operating system. Apps are the primary reason for many, and if anyone is choosing to root the Android OS for a different reason, it is usually so they can install a custom recovery and find some aftermarket ROMs to install over the stock ROM. You do not need a custom recovery to start installing your root apps like the Titanium Backup or Triangle Away app, but you will need root and a recovery if you are wanting to start installing some custom ROMs like what the CyanogenMod team have been working on lately.

Getting back to basics, removing the system apps is what you want if you want to keep the stock ROM but have it completely debloated so your battery lasts longer, and the hardware can offer you better performance. There are a few ways in which one can remove the system apps. The way I usually do it is by using the Titanium Backup app, but the other viable way is to install the dedicated System App Remover application. Both offer you the chance to remove all system apps. Titanium is great because it provides you backing up and removal of apps you do not want all on the one app, so you do not have to use up additional storage space in another app to do two jobs. The Titanium app gives users the option to free apps and not completely uninstall them, which means you do not have to have excellent knowledge with which apps can be removed. Only freeze them instead and if your system is not responding well, unfreeze them again and remember you need to have that one running. The only catch is the free version of the Titanium Backup app is what you can use to uninstall while the paid version is the only way to freeze apps.

Samsung Galaxy Note 3

The CF-Auto-Root file in this guide is based on the LRX21V.N9007ZHU3APC2 firmware which is part of an Android 5.0 Lollipop software update for some regions around the world. It does not mean you need to flash the LRX21V.N9007ZHU3APC2 firmware on your Samsung Galaxy Note 3 device at all. It is just there for you to use as an indicator. Some of the older Samsung devices do not boot old images.

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.

There will be some Android software updates for the Samsung Galaxy Note 3 SM-N9007 that bring new bootloader with them along for the ride. The bootloaders are usually only going to come with larger Android updates that update the device to new numbers like the jump from Android 4.4.4 KitKat to Android 5.0 Lollipop. Anyhow, if a new bootloader is present, Chainfire needs to apply updates to the files before they start to work for users. Common issues people face with a file that has not yet been updated by Chainfire include getting a device that does not boot after the flashing and getting a device that will not flash the file to begin. To fix these issues, Chainfire relies on people submitting the new recovery image that comes with the new firmware files that were part of the software updates that causes the issues. You can give him what he wants by submitting the updated recovery image to the official CF-Auto-Root thread made by Chainfire that sits on the XDA-Developers website. He will see your message and apply the necessary changes to get the rooting tool working again. Those changes that Chainfire makes will be automatically reflected in our guides so you do not have to worry about ours not being up to date. Our files are linking directly to Chainfire, so the updates are available as soon as Chainfire applies the updates.

In conclusion, that is how to root the Samsung Galaxy Note 3 smartphone running on the Android 5.0 Lollipop software update by using an updated versions of the CF-Auto-Root tool by Chainfire. The guide will work for all of the SM-N9007 model number running on the Android 5.0 Lollipop updates. Check if your Note 3 is rooted correctly by installing the root checker application from Google’s Play Store app on your smartphone once it reboots back into the normal mode.

There will be a few people who are suffering from some issues, and they can be fixed with some common troubleshooting techniques. The first thing you should try is using another version of the Odin flashing application because some people are reporting the CF-Auto-Root tool flashing for some devices on a particular version of the Odin flashing tool while other devices will not flash on that version. You can try installing an older version of the Odin flashing tool and seeing if that fixed your problem. Another common problem that arises with the CF-Auto-Root tool is from devices not getting into the recovery mode after the flashing completes. The developer of the rooting method states that each Samsung device must get into the recovery mode after the flashing or else you cannot expect that device to be rooted. Seeing a device get into the recovery mode is hard because the flashing happens so quickly. However, try booting into the recovery mode after the flashing manually just in case that is your problem.
