Chainfire is highly valued for his One-Click-Root solutions that are readily available for countless devices. We can’t praise them enough for being simple to use and delivering users with an experience as close to the stock Android as possible.

Firstly, you should understand that the Note 4 from Samsung comes in many model numbers. These numbers are dependent on which part of the world you are from. It doesn’t need to be confusing. You can check and identify yours easily by turning the tablet or phone on and navigating to the ‘Settings,’ followed by ‘About device.’ Now the model number is presenting itself on the screen. Always check that the number matches up with the corresponding number on the guide you are using. In this instance, that number is N910W8. We know this number is the Canadian edition, therefore all people residing in Canada have this code. That’s where the Note’s differences stop. Nothing else is any different from this Note 4 compared to any other.

Why would you look to unlock the OS? Root will officially unlock the system internals of any Android device. Follow the instructions listed below to remove the default factory restrictions in place by the manufacturers. We know Android 5.0 Lollipop is rolling out for the Nexus range as we speak thanks to the OTA service. We also know that Lollipop has added restrictions in place by Google to make rooting even harder. The large smartphone we have here is still running Android KitKat at the time of writing this. However, it isn’t long until the newfangled candy dessert is making its way to many of Samsung’s feature smartphones and tablet including this one.

The rooting operation is custom and unofficial. That means we are implementing steps against the manufacturers wishes and they are risky. They do void the warranty of the device. Given that this phablet is still relatively new, we know that most people’s warranties are still working. The great news is that you can return back to stock software versions later and take the root access away again. By doing so you are returning the flash counter back toward zero. Nobody can tell you tinkered with the system internals in the past after that happens. Therefore, you can send it away once again for repairs and they will look at it.

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.

  • The most important step now is backing up the device’s data. All data is vulnerable since opening it up out of the box. That’s why we suggest backing up the EFS folder, call logs, MMS and SMS texts, videos, pictures, music files, market applications and anything else you have installed on the device that you don’t want to risk losing. Countless people have their own way of backing up. You can go ahead with your own way or take some of our advice. We prefer to use Helium for Android available from the Google Play Store for syncing the contacts and backing up the apps. SMS backup+ is a great way to make copies of the text messages you don’t want to lose. There are many other options out there for you to explore to make copies of the rest of your data. Since this is a Samsung-based device, we know a popular way is using Samsung Kies. After Downloading Kies you can sync much of the device. Additionally, it doubles as a great way to install the latest USB Drivers.
  • Remember to disable Kies before starting the steps if you are choosing to use Kies for the USB Drivers. Otherwise you can install the USB Drivers from the official Samsung website or several other sources for the files.
  • The Odin tool we are using today is popular for flashing files with Samsung-based devices. It is made by the official Samsung Developers. However, it only works for Windows PCs ranging from Windows XP through to Windows 10. A new version is available for Windows 10.
  • Furthermore, you must stopover at the Developer Options menu and enable USB Debugging Mode. The menu is hidden in past version of Android operating systems. If it’s hidden for you, stopover at the build number and tap it seven times until it unlocks. The messages will count down the remaining tries on the screen.
  • Although there are countless guides using the tool under the same Chainfire name, it’s important to understand that the files diverge. That means this file is only for the Canadian model and no other. Do not try installing it on another model since it can soft-brick the device.
