Unrooting is the best way to go about getting your Huawei U8120 security back and working properly. When your Huawei device is rooted, it’s easier for malware to get access to your internal system through apps.

In addition to the extra security benefits, you can start installing official software updates again. If you accept OTA notification with root access, it can sometimes brick down the phone. The method we are using today for taking away the root access on the U8120 is flashing the stock ROM. Once we do this manually the first time, you can accept any future updates that happen automatically and directly to your device.

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 Files You Need

  • Download the Huawei stock ROM from this page.
  • You need a Windows computer to follow this guide. The safest way to install the stock Android ROM is to transfer it from the computer to the phone. Do not attempt to install the file directly to the smartphone form the link above.

Unrooting The Huawei U8120

  1. Download the stock ROM from above to the desktop of the Windows computer.
  2. Connect the Huawei U8120 to the computer by using the USB cable you usually use for charging.
  3. Extract the stock ROM on the desktop by right-clicking over the file and selecting the ‘;extract here’ option.
  4. Once you have extracted the file, you should see the dload file inside.
  5. Copy that same dload folder from the computer over to the internal storage SD card on the smartphone.
  6. Once you are satisfied the dload folder is on the SD card, unplug the phone from the computer.
  7. Completely power off the Huawei smartphone by holding in the Power key until you know it is off and not just sleeping.
  8. Reboot the U8120 by holding the Volume Up + Red + Power buttons.
  9. Using that same three button combination should automatically now flash that stock Android ROM on your device.
  10. Wait until the ROM is done installing; you will get a progress bar on the display to watch.
  11. Reboot the smartphone and you’re done.
  12. Now that your device is unrooted, you should find the warranty working again and you can accept any OTA notifications.

Test out the root checker app and see if it says you don’t have root access anymore.
