Assalam-o-Alaikum!

Greeting to all or any Steemains. Hopefully, you all are fine and enjoying an excellent and blessed life with the grace of GOD. I am @itszohaib87 today my topic is How to downgrade from Android 11 to Android 10 You’re visiting must do some things before you'll be able to revert to a stable Android 10 build, though. Firstly, make sure to duplicate all of your data before even attempting this. you may lose your device data, as this method requires a tool wipe, and your device is wiped several times during this process.

1. Download and install the Android SDK Platform-Tools package

You’ll use ADB or Android Debug Bridge to downgrade your current Android build to an older version. We recommend installing the unzipped platform-tools package on your desktop for quick access when running commands. you'll download the newest platform-tools zip file from here.

2. Enable USB debugging and OEM unlocking

Firstly, make sure that you have got Developer Options enabled on your Pixel, you'll do this by heading to your device Settings > About phone, now tap “Build number” until a message confirms that you just have Developer options enabled. Now you would like to go to Settings > System > Advanced > Developer options (you may have to expand a hidden menu for this). Before we can continue, you'll have to scroll down and enable “OEM unlocking” as this can be integral for further steps. Now scroll slightly further right down to the “Debugging” section and tap the “Allow USB debugging” option.

3. Download the Factory Image for your device

This is necessary for the Android 11 downgrade process. You’ll download the proper Factory Image for your device. this is often essentially just a blank slate for your smartphone or snapshot of that individual Android build at that point. you'll be able to grab it from Google’s Factory Image OTA hosting site, which contains all Factory Images for Pixel and Nexus devices. You will have to add this file and unzip its contents to the platform-tools folder for access anon.

4. Boot into device bootloader

This can be done in a pair of the way. the only way is to attach your device to your Windows PC and open the platform-tools folder and type “cmd” into your file manager address bar. this may open an electronic communication window within the right place, now enter the subsequent command to begin the ADB daemon: ADB reboot bootloader Pixel device will now load into the bootloader, which is where we’ll have to be to send some commands.Alternatively, you'll be able to press and hold the facility button and volume down key until you see the Android figure lying down. Now you'll have to press and hold the ability button and volume up button briefly before releasing the quantity up key. Using the up and down volume buttons, you'll be able to scroll to pick out “enter fastboot.”

5. Unlock the bootloader

Unlocking the bootloader is critical for the flashing process, as unfortunately you can’t flash a Factory Image and downgrade your Android version using the marginally simpler ADB sideloading method. this is often a reasonably simple process though. When using your command-line interface, enter the subsequent command:

fastboot flashing unlock

You will get a rather daunting message on your display warning you that unlocking the bootloader may cause device instability. Using the physical volume keys, choose the “Unlock the bootloader” option and make sure your selection by pressing the ability button. Restart your Pixel, as this process will wipe your smartphone.
We will also skip the device startup process to re-enable USB Debugging in preparation for the following step. Once you have got done so, ensure your Pixel is connected to your PC, and you’ll have to enter the bootloader on your device with the subsequent command again:

ADB reboot bootloader

6. Enter the flash command

With all of your Factory Image files extracted into the platform-tools folder and accessible. you'll be able to now run the subsequent command (with your open Command Prompt/PowerShell window):

flash-all

Your Pixel will now begin the method of downgrading Android, which can take some minutes. Leave the electronic communication window open, and when the method has finished, you'll see a completion message.

7. Relock the bootloader (optional)

This is an optional step but is required if you wish to induce future OTA updates. Otherwise, you’ll see a pop-up splash screen with a warning every time you reboot your device.
You will undergo the device setup process again which you'll be able to skip wholesale. From here, return and re-enable USB debugging from step No 2 — your bootloader is unlocked so OEM unlocking should be grayed out.
Plug your device back into your Windows PC and open your platform-tools folder and reopen an electronic communication window using the “cmd.” Enter the subsequent command to quickly load into your device bootloader: ADB reboot bootloader

8. Reboot your phone

You can now disconnect your device and reboot as you've got successfully downgraded from the Android 11 developer preview to Android 10. It should now load into the device setup process, allowing you to sign on and luxuriate in your stable Android build. It’s also worth noting that this method will work if you are doing wish to downgrade from Android 10 to Android Pie on devices like the Pixel 2 and Pixel 3. However, we don't recommend doing so, as this brings about various device security risks and further potential issues. That said, if you are doing prefer to downgrade from one Android version to a different one, then you are doing so at your own risk. Another thing to notice is that for those with a Pixel 4 series device, Face Unlock will now not be ready to be founded on a tool that's running Android 10 if it's previously run an Android 11 Beta build. this suggests that flashing back may only be worthwhile if you're happy to own Face Unlock and associated features disabled for the foreseeable future.
