Google has presented the final version of Android 11. You can install the firmware “over the air” and using a computer, but on a limited list of models.

How to install Android 11 on a smartphone

The list of devices that can be upgraded to Android 11 is quite extensive. It includes smartphones Galaxy S10 / S 20 / Note 10 / Note 20 / A, Xiaomi Mi 9 / Mi 10, Huawei P20 / P30 / P40 / Mate 20 / Mate 30 / Mate 40, Honor 20, OnePlus from the sixth model, and also Oppo, Realme and Vivo of the last two years.

Upgrading over the air is the easiest way to install Android 11. To do this, you need to do the following: Settings – System – Advanced – System update. If everything is done correctly, the smartphone will start looking for an update. There are times when it does not appear, then the written manipulations should be done anew. If successful, the screen will display the message “Download and install”. After clicking on it, it remains only to give consent in response to further actions of the system.

Installing Android 11 via PC is noticeably more difficult. To force the update, the user first needs to download the Android SDK from the Android Developer portal. Next, you need to open a command line or terminal, depending on the home OS, and run the downloaded file.

When the SDK is installed, you need to enable developer settings and USB debugging. To do this, you need to go along the following route: Settings – System – About phone – Build number. You need to click on the last field seven times, after which a window will appear at the bottom of the screen in which it says “You are now a developer.” Having rolled back to the “System” item, you can see the new available option “Developer options”, where you need to go.

Once inside, you need to enable USB debugging, then connect your smartphone to your computer and click “OK”. You can use the adb devices command to make sure the PC is functioning properly with the device. If the gadget is not authorized, you need to give it permission.

The next step is to unlock the bootloader, which only happens when the smartphone is turned off. You can get to the bootloader menu by holding the power and volume down button, or by using the command line and typing adb reboot bootloader in it. After that, you should set the fastboot flashing unlock command and confirm your actions in response to the device's request using the volume buttons to navigate to the desired answer and the power button to select it. Next, you need to enter fastboot reboot-bootloader.

Now it's time to update the OTA. To do this, you need to issue the adb devices command and make sure that the device is connected. Then you should put the smartphone into bootloader mode, which is done by the same manipulations with buttons and command line or terminal that were described earlier. Use the volume down button to reach the “Recovery mode” item. By selecting it, you can find that the device seems to reboot, and after that Android appears on the display with a red exclamation mark.

The user enters recovery mode after holding down the power buttons and increasing the volume. Inside, you must select the “Apply update from ADB” option and enter adb sideload [name of the OTA file] .zip. To make it easier, the file can be renamed in advance to a more simplified combination of letters and numbers. In the recovery mode, the update status will appear, the completion date of which depends on its size. As soon as the process is over, the system will restart and the smartphone will return to the standard Android screen.
