Samsung makes some of the best smartphones in the world, but they also come with a lot of additional data automatically on your smartphone that most people don’t want. Thankfully with root access to Samsung’s internal system, we are then able to remove the data which then gives us better performance.
We reap the rewards of the extra performance with the battery life being noticeably better and the operating system working faster. Once you remove most of the Samsung system apps you don’t want, the RAM will be freed up, and that helps your hardware work better. It also means there is less going on with your Samsung’s internal system which means the battery doesn’t have to work as hard.
The rooting file in this guide is based on LMY48B.J500MUBU1AOJ1 firmware which is part of a larger Android 5.1.1 Lollipop update. It does not mean you need to be flashing that same firmware build ID on your Samsung Galaxy J5 smartphone before starting with the guide.
Chainfire gives us that build ID just to use as an indicator. He says that some of the old Samsung smartphones and tablets will not boot some of the older images. That means you might be better off updating to a newer firmware if yours is not working.
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.
Files You Need
- Download the updated CF-Auto-Root package for the SM-J500M on Android 5.1.1 from here.
- We recommend unlocking your Samsung Galaxy J5 smartphone before you start the guide hen flashing a firmware build from one of the most popular smartphone carrier networks on the SM-J500M model number. Once you SIM unlock your Samsung Galaxy J5 smartphone, you are then able to flash any firmware so long as it is made for the same model number.
- It’s difficult for Chainfire to keep up with software updates that roll out to so many Samsung devices. The firmware update presents a problem for him because updates can come with new bootloader and that new bootloader can break the rooting method until he fixes it later. You know this is happening if your device doesn’t boot after flashing the CF-Auto-Root. You can fix it by booting into download mode and connecting it to the computer to flash a new stock ROM with the Odin flashing tool. You should also report any problems to the official CF-Auto-Root XDA Developers thread along with the new recovery.img your firmware has. He needs the updated recovery.img to fix the problem.
- Double-check the model number in the file matches up with the model number in your hands. The wrong model number can result in a bricked device.
- By rooting the Samsung Galaxy J5 smartphone, you agree to void the warranty so you can no longer send the device away for free repairs. You can unroot by flashing the stock ROM, and it will make the warranty work again provided that your device does not come with Samsung’s Knox security. Using the CF-Auto-Root tool does trip Knox and give the warranty void status.
Rooting the Samsung Galaxy J5 SM-J500M running Android 5.1.1 Lollipop software updates
- Enable the USB Debugging Mode on the Samsung Galaxy J5 smartphone before you follow the rest of the guide.
- Log in to the Windows computer as an administrator or else the Odin flashing tool will not work.
- Download and install the USB Drivers from the official Samsung website. (You install the drivers by downloading them and then opening the folder where the file awaits. Double-click on the driver file and it will open up the driver program. Click the Next > Next > Finish and the drivers are installed. Now you can continue with the guide).
- Extract the rooting file for the J5 to the desktop of the computer and you should see the Odin flashing application and the rooting files you need.
- Double-click the mouse on the Odin flashing app and wait for the user interface to open.
- Boot the Samsung Galaxy J5 SM-J500M into download mode and connect it to the computer with the same USB cable it comes with out of the box.
- Wait for around 10 seconds and you should see a blue or yellow color from the ID: COM port on the Odin user interface letting you know that your device is added. (No color means you need to get the drivers working, which often means rebooting the computer or logging out and back in once again.)
- Click the AP button or the PDA button and browse the desktop for the rooting file you extracted earlier.
- Do not make any changes to the default settings you get from the Odin user interface.
- Click the Start button and wait for the rooting exploit flashing to complete.
- You know it’s done when you see the Samsung Galaxy J5 display say it is installing the SuperSU, cleaning up the cache partition, reflashing the stock recovery and then rebooting.
- Look at the Odin user interface on the computer and it should now show a green box with a pass message inside the box.
In conclusion, that’s how to root the Samsung Galaxy J5 SM-J500M smartphone using the CF-Auto-Root application by Chainfire. The smartphone will reboot from recovery back to normal mode, and you will find the SuperSU from the app drawer.
It all happens very quickly, but your Samsung Galaxy J5 smartphone gets into recovery mode when it is flashing the SuperSU, cleaning the cache and then restoring the stock recovery, and it’s a requirement for the rooting to work. Anyone who does not find the SuperSU from the app drawer might have suffered a similar fate of the device not getting into recovery mode as it needed. If that happens to you, try rebooting to the recovery mode manually after the flashing completes and it should help.
Furthermore, anyone who is still not finding the Samsung Galaxy J5 smartphone rooted should install a new version of the Odin flashing tool from our page. The Odin application comes in a few versions and sometimes people need to try a few versions before one works for their Samsung Galaxy J5 smartphone.
