The Samsung Galaxy S7 is a remarkable smartphone that offers a high level of customization, especially when you root it. However, there may come a time when you need to unroot your device, whether it’s to regain your warranty, to resolve stability issues, or to prepare for a software update. This guide will walk you through the process of unrooting your Galaxy S7 while preserving your data and ensuring your device remains in optimal condition.
Understanding Rooting and Unrooting
Before diving into the unrooting process, it’s essential to understand what rooting and unrooting entail.
What is Rooting?
Rooting is a process that allows users to gain superuser permissions on their Android devices. This means you can access and modify system files, uninstall pre-installed apps, and customize your smartphone beyond the limitations set by the manufacturer. While rooting can enhance your device’s performance and add features, it also comes with certain risks, such as voiding your warranty and increasing vulnerability to malware.
What is Unrooting?
Unrooting is the reverse process of rooting. It restores your device to its original state, effectively removing root access and any modifications made while rooted. Unrooting can help you regain your warranty, secure your device against potential vulnerabilities, and prepare it for official software updates.
Reasons to Unroot Your Galaxy S7
There are various reasons users choose to unroot their Galaxy S7. Here are significant ones to consider:
- Regaining Warranty: Most manufacturers void the warranty if a device is rooted. Unrooting ensures that your warranty remains intact.
- Software Updates: Rooted devices may not receive official software updates due to modified system partitions. Unrooting prepares your phone for the latest updates.
Preparing for Unrooting
Before starting the unrooting process, ensure you take the necessary precautions. This includes:
Backing Up Your Data
Although unrooting is generally safe, it’s always wise to back up your personal data. Use Samsung Smart Switch or another backup solution to safeguard your contacts, photos, apps, and other crucial files.
Checking Root Status
To confirm if your Galaxy S7 is rooted, you can use apps like Root Checker, available on the Google Play Store. This simple utility checks for root access and informs you of your device’s current status.
Methods to Unroot Your Galaxy S7
There are multiple ways to unroot your Galaxy S7. Here, we’ll discuss two of the most effective methods: using SuperSU and using Odin.
Method 1: Unroot with SuperSU
If you rooted your Galaxy S7 using SuperSU, unrooting it is fairly straightforward. Follow these steps:
Step 1: Open SuperSU
Launch the SuperSU app on your device. If you cannot find it, you may need to download it again from the Google Play Store.
Step 2: Go to Settings
Once the SuperSU app is open, navigate to the “Settings” tab.
Step 3: Full Unroot
Scroll down until you find the option called “Full Unroot.” Tap on it. The app will prompt you with a confirmation dialog. Proceed with the unroot.
Step 4: Reboot Your Device
After the unrooting process is complete, reboot your Galaxy S7. Upon startup, your device should no longer be rooted. You can verify this by using the Root Checker app again.
Method 2: Unroot Using Odin
If SuperSU is not available or you encountered issues, you can use Odin to flash the stock firmware, effectively unrooting your device.
Step 1: Download Odin
First, you need to download the latest version of Odin from a reliable source like XDA Developers. After downloading, extract the files to your computer.
Step 2: Download Stock Firmware
Next, download the official stock firmware for your Galaxy S7. You can find the firmware on websites like SamMobile. Make sure to select the correct model number for your device.

Ensure you have Samsung USB Drivers installed on your computer. This will help Odin recognize your device when connected.
Step 4: Boot Your Galaxy S7 into Download Mode
To do this, power off your device completely. Press and hold the Volume Down, Home, and Power buttons simultaneously until you see a warning screen. Press the Volume Up button to enter Download Mode.
Step 5: Launch Odin
Open the Odin application on your computer. Connect your Galaxy S7 to your PC using a USB cable. You will see a blue box in Odin, indicating that the device has been recognized.
Step 6: Load the Firmware
In Odin, click the “AP” button (or “PDA” on older versions) and select the downloaded stock firmware file (it should have a .tar.md5 extension).
Step 7: Start the Flashing Process
Make sure that the “Auto Reboot” and “F. Reset Time” options are checked in Odin. Once you are ready, click the “Start” button. Odin will begin flashing the stock firmware to your device.
Step 8: Reboot Your Device
After the flashing process is complete, Odin will show a “Pass” message, and your device will reboot automatically. Once it’s restarted, your Galaxy S7 should be unrooted and restored to its original firmware.
Troubleshooting Common Issues
While unrooting your Galaxy S7 is generally a safe process, you may encounter some issues. Here are common problems and how to resolve them:
Device Fails to Boot
If your device enters a boot loop after unrooting, you may need to perform a factory reset. To do this, boot into Recovery Mode by pressing and holding the Volume Up, Home, and Power buttons simultaneously. Once in Recovery Mode, choose the “Wipe Data/Factory Reset” option.
Odin Fails to Recognize Device
Ensure you have the correct USB drivers installed and use a reliable USB cable. Try different USB ports on your PC if the issue persists.
Post-Unrooting Tips
After successfully unrooting your Galaxy S7, here are a few tips to enhance your device’s performance and security:
Install a Reliable Antivirus
With your device now back to its stock state, it’s crucial to have a reliable antivirus application installed to safeguard against potential threats.
Regularly Update Your Device
Make sure to check for official software updates regularly. Keeping your device updated ensures access to the latest features and security enhancements.

What is unrooting, and why would I want to unroot my Galaxy S7?
Unrooting is the process of removing root access from your Android device, returning it to its original state as designed by the manufacturer. Users often root their Galaxy S7 to gain administrative privileges, allowing them to install custom ROMs, delete bloatware, and access advanced features. However, there are several reasons a user might wish to unroot their device, such as improving device stability, receiving official software updates, or preparing to sell the device.
By unrooting your Galaxy S7, you ensure that the device runs smoother and is less prone to crashes, as it returns to the factory settings. Additionally, unrooting can help in avoiding compatibility issues that may arise from third-party applications or custom ROMs. If you’re facing problems with apps that require the device to be unrooted, like banking apps or secure applications, unrooting offers a remedy to these limitations.
Will unrooting my Galaxy S7 void the warranty?
Generally, rooting a device does void its warranty since it alters the software in a way that the manufacturer doesn’t support. However, unrooting your Galaxy S7 can restore its factory settings, which may help you circumvent warranty issues. It’s essential to note that some manufacturers might still detect traces of rooting even after an unroot, so there’s no guaranteed way to ensure that your warranty will be reinstated.
To increase the chances of your warranty being honored, it’s advisable to perform a complete unroot using reliable methods or tools specific to the Galaxy S7. If you’re concerned about warranty implications, consider contacting your manufacturer or carrier for clarity on their policies regarding rooting and unrooting before starting the process.
How do I know if my Galaxy S7 is rooted?
You can check if your Galaxy S7 is rooted by using a root checker application, which is available for free on the Google Play Store. These apps will run a quick test to determine whether you have root access enabled. If the test indicates the device is rooted, that means you can proceed with the unrooting process if you decide to do so.
Alternatively, you can look for the presence of certain apps on your device that are commonly used for rooted devices, such as SuperSU or Magisk Manager. If you find these applications installed, it’s a clear sign that your device has been rooted. Additionally, any custom recovery, like TWRP, would further confirm that rooting has taken place.
Can I still receive OTA updates after unrooting my Galaxy S7?
Once you successfully unroot your Galaxy S7 and restore it to its factory settings, you should be able to receive official Over-The-Air (OTA) updates. The unrooting process reverts the device to its stock firmware, allowing it to interact with the update servers without any issues. Updates often fail on rooted devices due to modifications made to the system files, which can cause verification failures.
However, it’s important to confirm that you have restored the stock recovery and system partition. If any remnants of the rooting process remain, you might encounter difficulties in receiving updates. To enhance your chances of getting future updates, ensure that your device is compatible and that no additional customizations are applied after unrooting.
Is unrooting safe for my data and applications?
Generally, unrooting your Galaxy S7 is a safe process, especially if you follow a reliable guide or use trusted software. However, there’s always a small risk associated with any process that modifies the system, as unforeseen issues can arise. To mitigate these risks, it’s recommended to back up your data before proceeding with the unrooting procedure. This includes your apps, contacts, photos, and any important files that you don’t want to lose.
After successfully unrooting, your installed applications should remain intact, but there’s a possibility that some apps designed specifically for rooted devices may not function correctly. Additionally, if you’re returning to stock firmware, certain customizations or apps may also be removed in the process. Always ensure that you have backups in place to restore any lost data quickly.
What tools can I use to unroot my Galaxy S7?
Several tools can effectively unroot your Galaxy S7, with one of the most popular being SuperSU’s unroot feature if you used SuperSU to root the device initially. This method is straightforward, usually just requiring a few clicks to restore your device to its non-rooted state. Besides SuperSU, tools like Magisk Manager can also be utilized if that was your method of rooting, providing an equally efficient unrooting process.
Another highly recommended option is using Samsung’s official software, Smart Switch. This allows users to restore the device to its factory settings, which effectively removes any root access in the process. Additionally, forums like XDA Developers often have threads specifically dedicated to unrooting tools and methods designed for various Android devices, including the Galaxy S7. Always research and follow the instructions carefully to ensure a smooth unrooting experience.
