Third Method: Installing Android 11 Beta by Flashing through the Bootloader

This is a back door method, which would give you complete control over Android 11 experience, here you need to flash the factory image.

Kindly keep this in mind that it is strongly recommended that you should have previous knowledge of working with the android SDK (software development kit) and the terminal (OSX or Linux) or command Prompt (windows), as this will come handy if something goes wrong while following this process.

In case you want to download Android SDK, you can download it from the Android Development website and follow the instructions to install it correctly. To follow the process , all you need is the adb and fastboot files which are located in the Platform tools folder, so kindly make sure that you read the description at the developer site and grab the right download. In addition to this ,all the following commands are written as they would be in terminal “J” seen in the guide.

Unlocking the boot loader

Pixel phones normally have a boot loader which should be unlocked. If you want to flash the software manually, you will need to do this.

  • First you should boot in to your bootloader. To do this you can either manually turn off your phone and hold down the power button and volume down button , this will show you device’s boot loader menu or you can enter below commands in your terminal or command prompt.
  • Run the following command to make sure that your device is properly connected to your computer. If it returns a string of characters then you are all set to update your device.

./adb devices

  • After this enter into the bootloader menu run the below command

./adb reboot bootloader

  • Now if you look at the bottom of the screen, there will be list of several things, which includes the device lock state. Device lock state should ideally say Locked unless and until you have unlocked your bootloader in the past and never went back and locked it again.
  • If you Device lock state is locked then you need to unlock your bootloader , this is required only when you are flashing a stock firmware image. You need to enter below command.

(kindly note while you are unlocking the device bootloader it will factory reset your device , so you will loose whatever is stored on it. In case if you missed to back up something important on your device you can hit the power button while start is highlighted in the bootloader menu and this will boot you back to your device like normal)

./fastboot flashing unlock

Now a dialog will appear on the device asking if you are sure of unlocking the bootloader. Again this will factory reset your device, so if at all you want to back out of the process you just need to select no with power button. if you are ready to unlock your bootloader you have to press the Volume up button and the Power button to confirm that you wish to unlock your bootloader.

./fastboot reboot-bootloader


Flashing the OTA update or Stock Image

Now you have unlocked your boot loader, its time to flash the new firmware into your device. To find the images, head over to Android 11 Factory Images page find your device, and download the latest image.

It is easier to un- compress the file in the Platform tools folder which you have downloaded. This will reduce the strain of typing the different path to the different files while flashing the firmware. (Else if you know how to drag a file into the terminal window to copy the path, just do that).

Now to begin make sure you are still in the bootloader menu on your device and double check that your bootloader is unlocked and make sure the communicating properly with your device. If your device’s serial number comes back as a connected device then you are ready to begin the update.

./fastboot devices

Once you have verified that the phone and the computer can communicate the way they need to, you can get to flashing.


Flashing  full Factory image

First, you’ll need to flash the updated bootloader with the following command.

./fastboot flash bootloader [bootloader file].img

once you type this commence you will not see anything on the screen of your device but there should be a dialog in your terminal or command prompt. When flashing bootloader the bootloader is done, you will be rebooted back into the bootloader to make sure everything is working correctly.

You will not see anything on the screen of your device but there should be a dialog in your terminal or command prompt. When you are done with flashing the bootloader, you should be rebooted back into the bootloader to make sure everything is still working correctly.

./fastboot reboot-bootloader

After this you need to flash the updated radios, this step is required only if you are updating the firmware of a phone or tablet that as cellular radios built into it.

./fastboot flash radio [radio file].img

./fastboot reboot-bootloader

After this, the final step is to flash the actual system image into your device.

(kindly note: the below line of code will wipe your device. Normally, you can remove the “-W” from the comman but when moving to a beta version of android its not guaranteed to work)

./fastboot -w update [image file].zip

After this step, your device will automatically restart and boot up normally. As this process has wiped all your data from the device , it will longer the usual boot time.

Once you have been greeted with the device setup walkthrough process , you will know that you have successfully flashed a new version of the firmware

When this is done, your phone will restart itself and boot up normally. As this process clears all data from your device, it will take slightly longer for your device to boot up for the first time. Once you have been greeted with the device setup walkthrough process, you know you have successfully flashed a new version of the firmware.

Last but not the least In case if you don’t want to enter the commands manually there scripts included in the compressed folder containing system image that will do most  but not all the work for you.

The flash all scripts files will automate the flashing of the bootloaded, radios and system image. You just need to make sure that your phone is in the bootloader menu and its boot loaded must be unlocked before starting the script. If these are not done, the script will fail to run and nothing will happen.


So what is next after this Beta version?

According to Google’s latest time line, there will be four beta releases ( one more left after this). The first was released in early june (delayed from their actual schedule which is early May), the second in Mid –july, the third (latest) in the early August, the final beta is expected to be in late  August or early septmeber
