How to Roll Back Android Update to an Older Version of Android

Rolling back an Android update to an older version can be a useful move if you’re experiencing performance issues, bugs, or simply dislike the features of the newer update. However, it’s not a straightforward process and involves certain risks. In this article, we’ll explore the methods and steps involved, while also discussing the potential pitfalls you should be aware of before proceeding.

Android updates usually bring exciting new features, improved security, and better performance. However, not every update works for everyone. You might experience bugs, slower performance, or incompatibility with your favorite apps. That’s when rolling back to an older version of Android can seem like an appealing option. But how do you actually go about downgrading your Android version? Let’s dive into the steps you need to follow and the potential pitfalls.

Things to Consider Before Downgrading

Rolling back your Android version is not as simple as hitting an “undo” button. Before you get started, it’s important to understand the risks involved.

1. You’ll Lose Data: Downgrading wipes everything from your device—apps, messages, photos, and other personal data. Therefore, it’s essential to back up your data before proceeding.
2. Warranty and Support Issues: Rolling back to an older version may void your device’s warranty, especially if it involves unlocking the bootloader. Manufacturers often view downgrading as tampering with the software.
3. Security Risks: Older versions of Android might lack the latest security updates, making your phone more vulnerable to malware and exploits.

Is It Possible to Roll Back an Android Update?

The short answer is, it depends. Some manufacturers provide official tools to flash an older firmware, but this is rare. In most cases, downgrading requires unlocking your phone’s bootloader and manually installing the previous version of Android. Not every device or version of Android can be rolled back easily, so it’s important to research your device model before proceeding.

Preparations for Rolling Back

Before rolling back your Android update, there are a few key steps to take:

1. Backup Your Data: Ensure all your important files are backed up, either through cloud services or by transferring them to your computer.
2. Charge Your Device: You don’t want your phone to die in the middle of the downgrade process, as this could cause serious issues like bricking your phone.
3. Enable Developer Options and USB Debugging:
   • Go to “Settings” > “About Phone.”
   • Tap “Build Number” seven times to unlock Developer Options.
   • Then go to “Developer Options” and enable “USB Debugging.”
4. Download Necessary Tools: Depending on your method, you might need software like Odin for Samsung, ADB and Fastboot for other devices, or a custom recovery tool like TWRP.

Methods to Roll Back Android Updates

There are two main methods for downgrading your Android device: installing a custom ROM or flashing official firmware manually. Let’s go over both.

Method 1: Downgrading Using a Custom ROM

A custom ROM is a modified version of Android that can be installed on your device to replace the current system. One popular custom ROM is LineageOS, which provides stable versions of older Android systems.

Steps to Install a Custom ROM:

1. Unlock the Bootloader:
   • Bootloaders are locked by default to prevent tampering with the operating system. Unlocking it is necessary but will erase all data.
2. Install a Custom Recovery (TWRP):
   • Download TWRP from its official site, and use ADB and Fastboot to install it.
3. Download the Custom ROM:
   • Find a reliable custom ROM that matches your device model.
4. Flash the Custom ROM:
   • Boot into the custom recovery (TWRP) and choose “Install.” Select the downloaded ROM file and follow the on-screen instructions.

Pros and Cons of Using Custom ROMs

• Pros: Greater control over the OS, faster updates (in some cases), and access to custom features.
• Cons: Stability issues, potential for bugs, and loss of manufacturer support.

Installing Custom Recovery (TWRP)

To install a custom ROM, you’ll need a custom recovery tool like TWRP. This tool replaces the default recovery mode and allows you to install new ROMs, make backups, and wipe data.

Steps to Install TWRP:

1. Download TWRP for your device.
2. Use ADB and Fastboot to install TWRP.
3. Reboot into TWRP to make sure it’s installed properly.

Flashing a Factory Image

A factory image is essentially the official, unmodified version of Android for your device, as provided by the manufacturer. Flashing a factory image can help you roll back your Android version to an earlier official release. This method is particularly useful for Google Pixel devices and Nexus phones, where official images are readily available.

Steps to Flash a Factory Image:

1. Download the Factory Image:
   • For Google devices, you can find factory images on Google’s developer site. Ensure you download the correct version for your device model and carrier.
2. Extract the Factory Image:
   • Unzip the downloaded image file to a folder on your computer. You’ll find files like boot.img, recovery.img, system.img, and a flash-all script.
3. Boot Your Phone into Fastboot Mode:
   • Turn off your phone and then press and hold Power + Volume Down to enter Fastboot mode. Connect your phone to your computer using a USB cable.
4. Run the Flash-All Script:
   • In the folder where you extracted the factory image, open a command prompt or terminal and run the flash-all.bat script for Windows or flash-all.sh for Mac/Linux. This will flash all components of the factory image to your device.
5. Wait for the Process to Complete:
   • The flashing process may take several minutes. Once it’s done, your phone will automatically reboot into the older version of Android.
6. Re-lock the Bootloader (Optional):
   • If you want to re-lock the bootloader for security reasons or to receive future official updates, reboot into Fastboot and enter the command fastboot oem lock. This will prevent further modifications to your phone’s system, but note that re-locking will wipe the phone again.

Using ADB and Fastboot for Downgrading

ADB (Android Debug Bridge) and Fastboot are powerful tools for managing Android devices from a computer. They are commonly used for flashing system images, sideloading updates, and more. When it comes to downgrading, Fastboot is the tool you’ll use to flash a factory image to your phone.

Steps to Downgrade Using ADB and Fastboot:

1. Install ADB and Fastboot on Your Computer:
   • Download the Android SDK Platform Tools from Google’s developer site. Extract the files to a folder on your PC.
2. Enable USB Debugging:
   • On your phone, go to Developer Options and enable USB Debugging. This allows ADB commands to interact with your device.
3. Boot into Fastboot Mode:
   • Power off your device and enter Fastboot mode by holding Power + Volume Down simultaneously.
4. Connect Your Phone to Your Computer:
   • Use a USB cable to connect your device. Open a command prompt or terminal in the folder where ADB and Fastboot are installed, and type fastboot devices to ensure your phone is detected.
5. Flash the Factory Image:
   • Extract the downloaded factory image, then use the command fastboot flash system system.img, replacing system.img with the correct file for your device.
6. Reboot Your Device:
   • After flashing, reboot your device with the command fastboot reboot. Your phone should now boot into the older version of Android.

How to Handle Bootloops and Bricked Devices

One of the potential issues with downgrading your Android version is the possibility of encountering a bootloop or, worse, bricking your device. A bootloop happens when your phone gets stuck in a cycle of rebooting and never fully powers on. Bricking refers to a state where your phone won’t power on or function at all. While both situations can be alarming, they’re often fixable.

Fixing a Bootloop:

1. Reboot into Recovery Mode:
   • Power off your device. Then, press and hold Power + Volume Up to boot into recovery mode.
2. Perform a Factory Reset:
   • In recovery mode, use the volume buttons to navigate to Wipe Data/Factory Reset. This will erase everything but can often fix bootloops.
3. Re-flash the Firmware:
   • If the factory reset doesn’t work, you may need to re-flash the correct firmware using the methods we discussed earlier (using Odin for Samsung, Fastboot for Google/OnePlus, etc.).

Fixing a Bricked Device:

1. Check if the Device Is Soft-Bricked:
   • If your phone still shows some signs of life (e.g., it shows the manufacturer’s logo or enters Fastboot/Download mode), it’s likely soft-bricked, not permanently damaged.
2. Re-flash the Firmware:
   • If your device enters Fastboot or Download mode, you can re-flash the official firmware. Follow the instructions specific to your manufacturer and device model.
3. Use Emergency Firmware Recovery Tools:
   • Some manufacturers offer tools for recovering bricked devices, like LG Bridge for LG devices or Odin for Samsung. These can help restore your phone to a working state.
4. Seek Professional Help:
   • If you’re unable to fix the device yourself, contacting customer support or taking it to a professional repair service is the best option.

Post-Downgrade Considerations

Now that you’ve successfully downgraded your Android version, there are a few things you should keep in mind to ensure your phone continues to function smoothly.

Restore Your Data:

• If you backed up your data before downgrading, it’s time to restore it. Use cloud services like Google Drive or local backups to bring your contacts, photos, and apps back onto your phone.

Update Apps:

• Some apps may not be compatible with older versions of Android. Head to the Google Play Store and update your apps, but be aware that newer versions of certain apps may not work perfectly on an older Android version.

Disable Automatic Updates:

• To avoid being forced back onto the newer version of Android, go to Settings > System > Software Update, and disable automatic updates. This will prevent your phone from updating itself without your permission.

Check for Security Updates:

• Just because you downgraded your Android version doesn’t mean you have to leave your device vulnerable to security threats. Some manufacturers still release security patches for older versions. Check for these in the Software Update section of your settings.
