The Samsung Galaxy S4 Zoom came out just over a year ago during June of 2013. The only phone carrier to pick the handset up was AT&T. That’s not a surprise because we always knew it was aimed for a micro niche of customers. Even thought it isn’t as popular as some of the other handsets under the Sammy name such as the Galaxy S5, the Zoom still was well catered for by developers and it wasn’t long after the release that it saw its first root access guide thanks to developers. Nonetheless, today we have a new way of unchaining the OS and opening it up to new potential with thanks to the Vroot tool made by popular developers Mgyun-team. The guys over a Mgyun make this tool available in more than one device, but here today we only have the instructions for the LTE variant of the aforementioned device name.
The beauty of using this method over the previous ways is that it will install TeamWin Projects recovery system instead of any other such as the ClockworkMod. Many people love to use TeamWin because they feel it is easier and quicker to do. The latter is true when it comes to the guide below. All up you will be out of here in a jiffy. Furthermore, we like to hope that people using the steps agree that it is the easiest method. As time goes on, our goal is to provide people who just that.
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.
Details of Note
- Until recently the tool we speak of here was available for the Chinese language only. However, they have started making the English version now too, so that even us westerns and people from other English-speaking countries can enjoy the program just the same. The writing is not in perfect English, but that doesn’t make the file any less trustworthy and everyone can still understand what they are trying to say. The file is available for over 8,000 different Android-based smartphones and tablets.
- Rooting the Zoom is the first step towards optimizing and customizing the possibilities with the operating system. Following the steps listed below will fill you in on everything you need to know in order to unlock the internal system and allow access to extras such as installing a custom ROM or Overclocking the CPU to boost the performance. In addition, there are a bevy of custom applications available — some paid and some free that will rock your world.
- Most people won’t have the Luxury of saving data to backup files since the Zoom comes with 8 GB of internal storage space that gives the end-user a maximum of 5 GB built-in space to use up. If you are one of the unlucky ones who can’t spare space to make copies of music, audio files, photo galleries, SMS and MMS texts, contacts and market apps there’s always the option of buying the MicroSD, microSDHC and microSDXC that gives an additional 64 GB of space from the external memory card.
- Since a laptop, notebook or computer with a USB slot is required to complete the steps, we won’t need a huge amount of battery power saved up before starting. The Zoom gives out 13 hours talk time and over 13 days standby time for the standard battery when brand new. That time, typically goes down the more you use it. Moreover, we know that this smartphone camera comes with the USB charging feature so it will charge the battery automatically provided it is drawing enough power from the computer. Save up at least 505 battery if the charging isn’t working when plugged in.
- Make sure you have USB Debugging Mode enabled from the Develop Options before starting. In addition, have the up to date Samsung USB drivers ready to go so we can successfully connect the two machines together.
- Stop the virus, spyware and malware protection from running both from the computer and phone. Visit the taskbar and system tray from a Windows PC and use the mouse to perform a right-click on the security icon. Navigate to the app drawer from the phone and find the security application from there.
