Method 1: Sideload Android 12 via Recovery and ADB
This method involves using the recovery mode on your device and the ADB (Android Debug Bridge) tool on your computer to flash the update .zip file. Recovery mode is a special mode that allows you to perform various actions on your device, such as wiping data, applying updates, or restoring backups. ADB is a command-line tool that lets you communicate with your device from your computer.
Step 1: Download the update .zip file on your computer
The first step is to download the update .zip file on your computer. This is the file that contains the Android 12 firmware for your device model. You can find it by searching on Google or visiting some popular websites like XDA Developers or Android Authority. Make sure you download the correct file for your device model and region. Once you have downloaded the update .zip file, you need to move it to a folder on your computer where you can easily access it. For example, you can move it to your desktop or your downloads folder. You also need to rename the file to something simple and easy to remember, such as update.zip.
Step 2: Enable USB debugging on your device and connect it to your computer
The next step is to enable USB debugging on your device and connect it to your computer. USB debugging is a feature that allows you to send commands and data to your device from your computer. To enable USB debugging, you need to go to Settings > About device > Build number and tap on it seven times. This will unlock the developer options menu. Then, go back to Settings > Developer options > USB debugging and turn it on. You may need to confirm this action by tapping on OK or Allow.
After enabling USB debugging, you need to connect your device to your computer using a USB cable. You may also need to select the File transfer or MTP mode on your device when prompted. You should see a notification on your device that says USB debugging connected. This means that your device is ready to communicate with your computer.
Step 3: Reboot your device into recovery mode and select "Apply update from ADB"
The third step is to reboot your device into recovery mode and select the option Apply update from ADB. Recovery mode is a special mode that allows you to perform various actions on your device, such as wiping data, applying updates, or restoring backups. To reboot your device into recovery mode, you need to turn off your device and then press and hold the Power and Volume up buttons together for a few seconds. You should see a screen with some options and a logo of an android lying down with an exclamation mark.
To navigate through the options in recovery mode, you need to use the Volume up and Volume down buttons to move up and down, and the Power button to select. You need to select the option Apply update from ADB. This will allow you to flash the update .zip file from your computer using the ADB tool.
Step 4: Use the adb sideload command to flash the update .zip file
The fourth step is to use the adb sideload command to flash the update .zip file from your computer to your device. ADB (Android Debug Bridge) is a command-line tool that lets you communicate with your device from your computer. To use the adb sideload command, you need to open a terminal or command prompt window on your computer and navigate to the folder where you have moved the update .zip file. For example, if you have moved the file to your desktop, you can type cd Desktop and press enter.
To flash the update .zip file, you need to type adb sideload update.zip and press enter. This will send the file from your computer to your device and start the installation process.

Congratulations! You have successfully updated your 8227l android device to Android 12 firmware using the sideload method. You can now explore the new features and improvements of Android 12 on your device.
Method 2: Flashing full Factory Image via Fastboot
This method involves using the fastboot mode on your device and the fastboot tool on your computer to flash the full factory image .zip file. Fastboot mode is a special mode that allows you to flash images or files directly onto your device's partitions. Fastboot is a command-line tool that lets you communicate with your device in fastboot mode.
Step 1: Download the factory image .zip file on your computer
The first step is to download the factory image .zip file on your computer. This is the file that contains the full Android 12 firmware for your device model. You can find it by searching on Google or visiting some popular websites like XDA Developers or Android Authority. Make sure you download the correct file for your device model and region.
Once you have downloaded the factory image .zip file, you need to extract it to a folder on your computer where you can easily access it. For example, you can extract it to your desktop or your downloads folder. You should see a folder with several files inside, such as boot.img, system.img, vendor.img, and flash-all.bat or flash-all.sh.
Step 2: Unlock your device's bootloader if it is not already unlocked
The next step is to unlock your device's bootloader if it is not already unlocked. Bootloader is a program that runs before the operating system and determines what to load. Unlocking your bootloader allows you to flash custom firmware or images on your device. However, unlocking your bootloader may void your warranty, erase your data, or cause security risks. Therefore, you should only unlock your bootloader if you know what you are doing and at your own risk.
To unlock your bootloader, you need to go to Settings > Developer options > OEM unlocking and turn it on. You may need to confirm this action by entering your PIN or password and tapping on Enable or Allow. Then, you need to reboot your device into fastboot mode and connect it to your computer using a USB cable. You can reboot your device into fastboot mode by turning off your device and then pressing and holding the Power and Volume down buttons together for a few seconds. You should see a screen with some information and a logo of an android with a red exclamation mark.
To unlock your bootloader, you need to open a terminal or command prompt window on your computer and navigate to the folder where you have extracted the factory image .zip file. For example, if you have extracted the file to your desktop, you can type cd Desktop and press enter. Then, you need to type fastboot flashing unlock and press enter. This will send a command to your device to unlock its bootloader. You should see a message on your device screen that asks you to confirm this action by pressing the Volume up button. Press the Volume up button to confirm and unlock your bootloader. You should see a message on both your computer and device screens that says Unlocking bootloader.... This may take some time depending on your device model.
Step 3: Reboot your device into fastboot mode and connect it to your computer
The third step is to reboot your device into fastboot mode and connect it to your computer using a USB cable. Fastboot mode is a special mode that allows you to flash images or files directly onto your device's partitions. To reboot your device into fastboot mode, you need to turn off your device and then press and hold the Power and Volume down buttons together for a few seconds. You should see a screen with some information and a logo of an android with a red exclamation mark.
To connect your device to your computer in fastboot mode, you need to use a USB cable that supports data transfer. You may also need to select the File transfer or MTP mode on your device when prompted. You should see a notification on your device that says Fasboot mode. This means that your device is ready to communicate with your computer.
Step 4: Use the flash-all script or flash each image file manually using fastboot commands
The fourth step is to use the flash-all script or flash each image file manually using fastboot commands from your computer to your device. Fastboot is a command-line tool that lets you communicate with your device in fastboot mode. To use the flash-all script or flash each image file manually, you need to open a terminal or command prompt window on your computer and navigate to the folder where you have extracted the factory image .zip file. For example, if you have extracted the file to your desktop, you can type cd Desktop and press enter.
If you want to use the flash-all script, you need to type flash-all.bat if you are using Windows or ./flash-all.sh if you are using Mac OS or Linux and press enter. This will run a script that will flash all the image files in the folder to your device automatically. You should see a progress bar on both your computer and device screens. This may take some time depending on the size of the files and the speed of your connection.
If you want to flash each image file manually, you need to type the following commands one by one and press enter after each command:
fastboot flash boot boot.img: This will flash the boot image file to your device's boot partition.
fastboot flash system system.img: This will flash the system image file to your device's system partition.
fastboot flash vendor vendor.img: This will flash the vendor image file to your device's vendor partition.
fastboot erase userdata: This will erase your device's user data partition. This is optional but recommended to avoid any issues or conflicts with your previous data.
fastboot reboot: This will reboot your device and boot into Android 12.
Step 5: Reboot your device and enjoy Android 12

How to troubleshoot common issues after installing Android 12 firmware
Sometimes, you may face some issues or problems after installing Android 12 firmware on your 8227l android device. These issues may be caused by various factors, such as incompatible apps, corrupted files, or incorrect settings. Here are some of the common issues that you may encounter and how to troubleshoot them:
Issue 1: Device stuck in bootloop or not booting up
A bootloop is a situation where your device keeps restarting or showing the boot animation without reaching the home screen. This may happen due to a faulty installation, a corrupted system file, or a conflicting app. To fix this issue, you need to wipe the cache partition or perform a factory reset from recovery mode.
Solution: Wipe cache partition or perform a factory reset from recovery mode
To wipe the cache partition or perform a factory reset from recovery mode, you need to reboot your device into recovery mode and select the option Wipe cache partition or Wipe data/factory reset. Recovery mode is a special mode that allows you to perform various actions on your device, such as wiping data, applying updates, or restoring backups. To reboot your device into recovery mode, you need to turn off your device and then press and hold the Power and Volume up buttons together for a few seconds. You should see a screen with some options and a logo of an android lying down with an exclamation mark.
To navigate through the options in recovery mode, you need to use the Volume up and Volume down buttons to move up and down, and the Power button to select. You need to select the option Wipe cache partition. This will clear the temporary files and data that may be causing the bootloop issue. You should see a message on your device screen that says Cache wipe complete. You can then select the option Reboot system now. This will restart your device and hopefully fix the bootloop issue.
If wiping the cache partition does not work, you can try performing a factory reset from recovery mode. However, this will erase all your data and settings on your device, so you should only do this as a last resort. To perform a factory reset from recovery mode, you need to select the option Wipe data/factory reset. This will erase all your data and settings on your device and restore it to its original state. You should see a message on your device screen that says Data wipe complete. You can then select the option Reboot system now. This will restart your device and hopefully fix the bootloop issue.
Issue 2: Device not recognized by computer or adb/fastboot commands not working
Sometimes, your device may not be recognized by your computer or the adb/fastboot commands may not work properly. This may happen due to various reasons, such as outdated or missing USB drivers, faulty or incompatible USB cable or port, or incorrect USB mode or settings. To fix this issue, you need to install or update the USB drivers for your device and check the USB cable and port.
Solution: Install or update the USB drivers for your device and check the USB cable and port
To install or update the USB drivers for your device, you need to download the latest USB drivers for your device model from the official website of your device manufacturer or from a reputable source online. You can search for them on Google or visit some popular websites like XDA Developers or Android Authority. Once you have downloaded the USB drivers, you need to install them on your computer by following the instructions provided by the source.
To check the USB cable and port, you need to make sure that you are using a USB cable that supports data transfer and not just charging. You also need to make sure that you are using a working and compatible USB port on your computer. You can try using a different USB cable or port if you have any doubts. You also need to make sure that you have selected the correct USB mode on your device when prompted. You can choose the File transfer or MTP mode for sideloading or flashing via recovery and ADB, or the Fastboot mode for flashing via fastboot.
Issue 3: Device performance or battery life degraded after updating to Android 12
Sometimes, your device may experience performance or battery life issues after updating to Android 12. This may happen due to various factors, such as app cache and data, incompatible apps, or unnecessary features or settings. To fix this issue, you need to clear app cache and data, uninstall incompatible apps, or disable unnecessary features or settings.
Solution: Clear app cache and data, uninstall incompatible apps, or disable unnecessary features or settings
To clear app cache and data, you need to go to Settings > Apps > See all apps and select the app that is causing the issue. Then, tap on Storage > Clear cache and Clear data. This will delete the temporary files and data that may be slowing down your app or causing errors. You can also clear the cache and data for all apps at once by going to Settings > Storage > Cached data > Clear cached data.
To uninstall incompatible apps, you need to go to Settings > Apps > See all apps and select the app that is causing the issue. Then, tap on Uninstall. This will remove the app from your device and free up some space. You can also check for updates for your apps by going to Play Store > Menu > My apps & games > Update all. This will install the latest versions of your apps that may be compatible with Android 12.
To disable unnecessary features or settings, you need to go to Settings > System > Advanced > Developer options and turn off any features or settings that you don't need or use.
