How To Install AOSP Android 14 on Xiaomi Mi 9 Lite (pyxis)
As the title indicates, this article provides the necessary steps and requirements to install the AOSP Android 14 build on the Xiaomi Mi 9 Lite (pyxis) model.
Before diving into the guide, please ensure you’ve met all the prerequisites listed below.
Pre-Requisites
Before we begin this procedure, I 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. Keep at least 50% of the 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 Xiaomi Mi 9 Lite.
Using the ADB and Fastboot commands (platform-tools), you can boot your Android device into the bootloader mode (download mode), making it easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and the 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 Xiaomi USB Drivers
To create a strong and successful connection between a mobile device and a computer using a USB data cable, you will need a USB Driver. It is essentially a set of files that enables you to transfer files between the connected devices, flash files on the handset, and much more.
It is important to note that USB drivers can be utilized and operated by mobile devices and other external devices on a Windows computer. These include but are not limited to mice, keyboards, printers, external hard drives, speakers, and USB flash drives. If you need to download Xiaomi USB drivers, you can find them here.
