The Lenovo A850 is a smartphone with a big display, dual SIM support, fast 4G mobile data support and a quad-core processor. It launched during 2013 after being announced back in August of the same year. The mobile starts with 4.2 Jelly Bean and hasn’t seen much love on the software front since then, making it the ideal candidate to unchain and open up the possibilities to install custom firmware and upgrade it further.
There are people who will finish the guide within a few minutes using the Framaroot tool that involves only one click. However, before we get stuck in the guide I recommend taking the extra time to go over the prerequisites for something to think about. Inside will be great tips on how to avoid trouble, what you may need to complete the guide as well as instructions on how to find them.
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
- You should know that the new method is made by XDA Developers member alephzain who goes on to post the steps in the thread that we link to so users can download the rooting package. Nonetheless, once you have the file come back here for a more detailed guide that is easier to understand.
- The safest way to use the files is by transferring them from the computer over to the smartphone. People can choose from either the notebook, laptop or full-size desktop PC for the exercise. All it needs is a working USB slot for the connection and it will work.
- While it is true, we connect to the computer to transfer the package, we don’t stay connected for a long time. Therefore, it’s a great idea to not rely on the USB charging feature. Make sure you have at least 40% battery power before starting the steps. The guide is short, so that will be plenty of time to get the job done even if you suffer from draining issues.
- Confirm the USB Debugging Mode is enabled by stopping over at the Developer Options menu. Likewise, have the up to date USB Drivers for a safe and secure connection between devices.
- In the wake of following the steps you will void any remaining manufacturers warranty left on the handset. However, you can get this back by restoring the stock firmware and taking away the root access. That will restore the flash counter back to zero and the manufacturer will not know you unlocked the operating system.
- We give the instructions to the best of our ability, but nothing is a guarantee. Moreover, if something were to go wrong, we are not responsible for any damages or loss of data. The A850 comes with 4 GB of built-in storage space and 32 GB from external SD card options.
- You will need the SD card option for the handset. Buy them online or from your local retailer.
- To make sure you do not lose data use the Titanium app if rooted or the Helium app to store the data and sync market apps. Use SMS backup to make copies of the text messages.
- Enable unknown Sources from the phones settings by navigating to Settings > Security.
