The Google Nexus 4 has another software update available, updating the OS to Android 5.1.1 Lollipop on LMY47V firmware.
If you are now running that latest firmware build on your smartphone, you can open up the ports with root access by following the guide after the drop.
This is how you go about getting root access to the Google Nexus 4 smartphone when it’s running on the Android 5.1.1 Lollipop software updates with the LMY47V firmware build number.
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.
- You need the Google Nexus 4 and not a different numbered device from the Google Nexus range. Moreover, you need to be running the LMY47V as we do not guarantee this guide works for future software updates above that.
BEFORE WE BEGIN
- Download the Google USB Drivers direct to the Windows PC you are using in conjunction with this guide. You might need to reboot that PC to have the drivers working. If the guide fails to work, that is the first thing to try.
- Enable the USB Debugging Mode by going to Settings > About Device > tap the build number seven times. Go back to the Settings, find the new Developer Options menu and enter it. Enable the USB Debugging mode option from inside there.
HOW TO ROOT NEXUS 4 ON ANDROID 5.1.1 LOLLIPOP LMY47V FIRMWARE
1. Visit the Android Developers website and download Android SDK.
2. Setup Android SDK, ADB, and Fastboot by reading our guide. Those who already have it don’t need to do it again.
3. Download the SuperSU. Do not unzip the file.
4. Download the TWRP recovery file. Save the TWRP file to the same location on the computer where you have ADB and fastboot.
5. Connect the Google Nexus 4 to the same Windows computer you have the files.
6. Transfer the SuperSU to the root of the SD card internal storage.
7. Completely Power off the Nexus 4 by holding down the Power button for 10 seconds.
8. Reboot the Google Nexus 4 to the bootloader mode: Volume Down + Power buttons.
9. Open the folder where you have the TWRP recovery, ADB and Fastboot and right-click on a white empty space and hold the Shift key. You should see a new menu pop up on the display, select the “open command window here” option from that menu.
10. Now type the following command in the command prompt utility: “fastboot flash recovery recovery-clockwork-touch-184.108.40.206-mako.img”
11. Once booted to fastboot, choose recovery from the menu, and you’ll be in recovery.
12. Now navigate to “flash zip from SD card” followed by “choose zip from sdcard.”
13. Upload the SuperSU file and confirm you want it to load.
14. Once complete, go back to the main recovery menu and reboot the system.
Now you are running the latest Android 5.1.1 Lollipop on LMY47V and have root access with TWRP recovery installed. Sometimes you need to install a custom recovery before you can get root access, and you’ll need to leave it there for as long as you keep root access because the only way to unroot is by flashing the stock ROM and that also happens to be what you do to get the stock recovery back on the device as well.
