ZTE make some amazing smartphones that are popular in the USA, Australia, Pakistan, Indonesia and other countries around the world. Cricket is a phone carrier network located in the United States and has over 5 million subscribers.

Their number one handset in the ZTE range at the moment is the ZTE grand Max +, and today I’ll show you how to root it so you can tinker with the OS, install a custom recovery, custom ROM and root-only apps from Google Play.

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.

This is what you need to get root access to the ZTE Grand Max Plus smartphone if you’re a Cricket subscriber by using the new and reliable KingRoot one-click rooting tool.


Although far from perfectly named because of the existing Kingo Root tool, the new King root tool claims to root every Android device out there. That’s the tool we are using today for the ZTE Grand Max +. However, this is not extensively tested. Those willing to be guinea pigs should be advanced Android users who know how to fix a bricked handset just in case. From there you can check the comments and see if people had success.


  • You need a Windows PC to download the King root tool.
  • Furthermore, you’ll want the ZTE USB drivers installed on the Windows PC so you are connecting the smartphone to the PC successfully.
  • King root will void the warranty, just like most other rooting guides.
  • Enable USB Debugging Mode: Settings > Developer Options > USB Debugging.


  1. Download the KingRoot app on the PC.
  2. Connect the ZTE Max + to the same computer as the file.
  3. Transfer the file over to the SD card storage (internal storage).
  4. Learn how to install apps outside of Google Play for that.
  5. After you launch the app, it should let you know if root is available.
  6. Tap the blue “Start Root” button and wait until it flashes on your device.
  7. The King One-Click rooting tool will give a confirmation message on the display when it’s done.
  8. Once you are granted the root privileges, root the smartphone manually yourself and the root is done.

Since this smartphone isn’t extremely popular just yet, you might find it difficult locating custom ROMS to install. That won’t limit your ability to enjoy all the usual applications from Google Play and other third-party sources. You can start by testing out the root checker app and checking this worked for you.
