What to know when downgrading Android?

Step-by-Step Guide to Downgrade

Here we have made a list of things we think you should know about the Android downgrade process. Keep an eye on them because they are important:

  • You will lose the warranty of your phone by downgrading it.
    • Going back to a previous version of Android will erase all data on your phone. This includes both the Android configuration data and apps, as well as everything you have saved in the internal storage. That is your photos, videos, documents, music, etc. will be deleted.
  • By default, your Google account will back up some data: contacts, photos, device settings, SMS, and call history.
    • Want to check if Google has already backed up your phone? Go to Settings > Google > Backup. Enable this option and create a backup now.
  • Many applications back up your settings automatically. So you don’t have to worry about backing up your data. This only applies to apps that work with cloud services, such as social networking apps.
    • There are other apps, such as WhatsApp, that allow you to create a cloud backup specifically for them from their own settings. This way, you can easily restore them with a single click of a button when opening the app after downgrading. If you are interested, check out this article on how to set up WhatsApp backup to avoid losing chats.
  • You can only downgrade if your phone manufacturer allows it. And is that to do this you must modify the firmware, unlock the bootloader, manually flash an Android image, and do other things that not all brands of smartphones allow you to do.
    • Almost all major Android brands allow this, but Google certainly makes it the easiest.
    • However, it is imperative that you have a carrier-unlocked version of the phone. Otherwise, it will be impossible to downgrade it regardless of the brand.
  • It is much more difficult to downgrade when there are no standard Android images for your phone. Brands such as Samsung, LG, and Motorola, among others, do not share publicly the Android images needed to revert to an older version of the system.
    • If this is your case, you will have to look for the image for your phone on third-party pages (with the risk that implies). Even if you find it, you may also have to change the bootloader and other elements of the system modified by the new version.
  • Don’t know where to find the factory image of your Android to downgrade? Here are the repositories we found for the main brands:

Follow these steps carefully:

  1. Boot your device into fastboot mode using key combinations or ADB commands.
  2. Unlock the bootloader using the fastboot unlock command. Confirm the prompt on the device.
  3. Flash the Android 11 firmware using the flash-all command. Do not disconnect mid-process.
  4. Once complete, reboot the system to boot into Android 11.
  5. Re-lock the bootloader to continue getting OTA updates using fastboot lock.
  6. Set up Android 11 and restore your data from Google and app backups.

Downgrading from Android 12 to Android 11: a step-by-step guide 10

The moment of truth has arrived. Here are the steps to follow to downgrade from Android 12 to Android 11:

  • Enable USB debugging on your device.
  • In Settings > Developer Options, also enable OEM Unlock.
  • Now you need to install ADB and Fastboot on your PC. There are many ways to do it, but we recommend you the official one that consists in downloading the Android SDK Platform Tools ZIP file from these links (just download the one that corresponds to the PC you have):
  • Unzip the ZIP file with a tool like 7-Zip and move the “platform-tools” folder to an easily accessible location on your PC.
  • The extract also the Android 11 factory image (which must be the specific one for your device, otherwise you will brick it) and move all its contents to the main “platform-tools” folder.
    • Now, connect your phone to the PC with its USB cable and make sure it recognizes it. If not, download the USB drivers for your phone and install them on the PC.
  • And don’t forget to accept USB debugging when you get the notification on your phone after connecting it to the PC.

  • Next, open the Terminal of your PC:
    • On Windows, you can do this by opening the “Run” application (search for it from the Windows search engine) and in it type “cmd” (without quotes).
    • On Mac, go to Applications > Utilities and double-click Terminal.
  • Next, type in the Terminal the command “cd” followed by the path to the “platform-tools” folder. That is to say, if you have the folder on the desktop, the command you will enter is this: cd C:\Users-name-your-name-on-the-platform-tools.
  • To verify that you have done everything right so far, enter the following command:
    • On Windows: adb devices.
    • On Mac: ./adb devices.
    • If your phone is connected correctly, its serial number should appear on the screen.
  • Is everything OK? Then proceed to enter Fastboot on your mobile like this:
    • Press at the same time the Power + Volume Down buttons until the Android error icon appears.
    • Press at the same time the Power + Volume Up buttons and release the Volume Up key.
    • That’s it! If you fail to enter Fastboot this way, then use these commands to enter: adb reboot bootloader (Windows) | ./adb reboot bootloader (Mac).
  • Then, unlock the bootloader with this command:
    • On Windows: fastboot flashing unlock.
    • On Mac: ./fastboot flashing unlock.
  • After entering the above commands, using the volume buttons on your phone select the option to unlock the bootloader and then confirm the action by pressing the power button. This will erase all data on your device and reboot it.

  • After rebooting, type this command:
    • On Windows: adb reboot bootloader.
    • On Mac: ./adb reboot bootloader.
  • With the bootloader unlocked and rebooted, you can now install Android 11 on your mobile with the downloaded factory image. How? On Google Pixel you just enter this command:
    • On Windows: flash-all.
    • On Mac: ./
    • Do not close the Terminal either during or after installation to avoid problems.
  • When the Android 11 installation is finished, you will see a confirmation message. At this point, you can disconnect your phone from the PC.
  • Although it is now possible to start the mobile configuration from scratch, the best thing to do now is to lock the bootloader again to continue receiving official Android updates. If you are not interested in receiving updates, you can skip the following steps and start using the phone.

  • To lock the bootloader, connect your phone to the PC again and enter this command in the Terminal:
    • On Windows: adb reboot bootloader.
    • On Mac: ./adb reboot bootloader.
  • After it reboots, type this:
    • On Windows: fastboot flashing lock.
    • On Mac: ./fastboot flashing lock.
  • Finally, manually lock the bootloader by choosing the option to do so with the physical buttons of the mobile.
  • Now, disconnect and close everything. Restart your mobile, start setting up Android 11, and restore all your data.
  • That’s it! We hope you found this guide useful to get back to Android 11. Don’t forget that some steps shown here may change depending on the brand of your phone, so we recommend you check each step at least twice before proceeding.
