How to Install AOSP Android 13 on Galaxy M21 (m21)
As the title suggests, we’ve shared the requirements and steps to flash the AOSP Android 13 build on the Galaxy M21 (m21) variant.
Before heading over to the guide, make sure to follow all the requirements below.
Before we begin with this procedure, I would strongly recommend you create a backup of your device storage and all your files stored on your device. Moreover, following the steps mentioned in this post carefully is advised to avoid permanent damage or bricking your device.
Charge Your Phone
It’s highly recommended to charge your handset before unlocking the bootloader to avoid your device from shutting down occasionally while going through the process. Make sure to keep at least 50% of charge or higher for a smooth operation.
Download ADB and Fastboot Binaries
You can skip this adb and fastboot part if you have already installed TWRP Recovery on your Galaxy M21.
Using the ADB and Fastboot command (platform-tools), you’ll be able to boot your Android device into the bootloader mode (download mode), which will be easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and computer to sideload files.
Fastboot is a more advanced command utility tool for Android devices that works with computers. You can download ADB and Fastboot Binaries (Platform-Tools).
Download Samsung USB Drivers
A USB Driver is a set of files that allows you to create a successful and strong connection between a mobile device with a computer properly using a USB data cable. It’ll be useful to transfer files between the connected devices, flash files on the handset, and more.
It’s also worth mentioning that mobile devices and other external devices can use and run USB Drivers on a Windows computer. Such as a mouse, keyboard, printer, external hard drives, speakers, USB flash drives, etc. You can grab Samsung USB Drivers here.
