Prerequisites for a Seamless LineageOS 23 Installation

Before embarking on the journey to flash LineageOS 23 Android 16 on your Poco F5, it is absolutely crucial to ensure that you have met all the necessary prerequisites. Skipping any of these steps can lead to data loss, device instability, or even a bricked device. We have detailed each requirement extensively to leave no room for error.

#### 1. Unlocking the Bootloader: The Gateway to Customization

The first and most critical step in installing any custom ROM, including LineageOS 23 Android 16, is to unlock the bootloader of your Poco F5. The bootloader is a piece of software that runs when your device starts up, initializing the hardware and loading the operating system. By default, manufacturers lock the bootloader to prevent unauthorized modifications. Unlocking it is essential to allow you to flash custom recoveries and ROMs.

• Backup Your Data: Unlocking the bootloader will factory reset your device, erasing all data, including apps, photos, videos, and internal storage contents. Therefore, a complete backup of all your important data is paramount. Utilize cloud storage, external drives, or other backup solutions to secure your files.
• Xiaomi’s Official Unlock Tool: Xiaomi, the parent company of Poco, provides an official method for unlocking the bootloader. This process involves using their “Mi Unlock Tool.” You will need to:
  • Enable Developer Options on your Poco F5: Go to Settings > About phone > Tap on “MIUI version” (or “HyperOS version”) seven times until you see a message stating “You are now a developer!”.
  • Enable OEM Unlocking and USB Debugging: Navigate to Settings > System > Developer options and toggle on “OEM unlocking” and “USB debugging”.
  • Link your Mi Account: In Developer options, under “Mi Unlock status,” tap “Add account and device.” Ensure you are logged into the same Mi account on your phone that you will use with the Mi Unlock Tool.
  • Download and install the Mi Unlock Tool on your computer.
  • Boot your Poco F5 into Fastboot mode: Power off your device. Then, press and hold the Volume Down and Power buttons simultaneously until the Fastboot screen appears (an Android robot with “FASTBOOT” text).
  • Connect your phone to your computer via a USB cable.
  • Run the Mi Unlock Tool on your computer. It will detect your device.
  • Follow the on-screen instructions within the Mi Unlock Tool. This process typically involves a waiting period (often 7 days, but it can vary) imposed by Xiaomi to prevent misuse. Once the waiting period expires, you can proceed with the unlock.
  • The Mi Unlock Tool will then initiate the unlocking process. This will erase all data on your device.

#### 2. Installing a Custom Recovery: Your Key to Flashing

Once your bootloader is unlocked, the next essential step is to install a custom recovery. A custom recovery, such as TWRP (Team Win Recovery Project), replaces the stock recovery environment and provides advanced functionalities, including the ability to flash custom ROMs, create and restore backups, wipe partitions, and more. For LineageOS 23 Android 16 on the Poco F5, TWRP is the recommended recovery.

• Download the Correct TWRP Image: Visit the official TWRP website or reliable XDA Developers threads for the Poco F5 (codenamed “marble”) to download the latest compatible TWRP recovery image file (usually a .img file). Ensure it explicitly states compatibility with your device model and the intended Android version.
• ADB and Fastboot Tools: You will need to have ADB (Android Debug Bridge) and Fastboot tools installed on your computer. These are part of the Android SDK Platform Tools. You can download them directly from the official Android Developers website.
• Flashing TWRP via Fastboot:
  • Ensure your Poco F5 is booted into Fastboot mode and connected to your computer via USB.
  • Open a command prompt or terminal window on your computer and navigate to the directory where you saved the TWRP .img file and your ADB/Fastboot executables.
  • Verify device connectivity by typing: fastboot devices (you should see your device’s serial number).
  • Flash the TWRP image by typing: fastboot flash recovery twrp_filename.img (replace twrp_filename.img with the actual name of your downloaded TWRP file).
  • After flashing, it is crucial to boot directly into TWRP recovery immediately. If you boot back into the system, the stock recovery might overwrite the custom recovery you just installed. To do this, with the device still connected and in Fastboot mode, type: fastboot reboot recovery or, if that doesn’t work, power off your device and then press and hold the Volume Up and Power buttons simultaneously until you see the TWRP splash screen.

#### 3. Downloading LineageOS 23 and GApps

With your custom recovery in place, you are ready to download the necessary software for your LineageOS 23 Android 16 installation.

• LineageOS 23 ROM: Visit the official LineageOS website (lineageos.org) and navigate to the devices section. Look for the Poco F5 (codenamed “marble”). Download the latest official build of LineageOS 23 Android 16 for your device. It will typically be a .zip file.
• Google Apps (GApps): LineageOS, by default, does not include Google applications (like the Play Store, Gmail, Maps, etc.) due to licensing restrictions. You will need to download a separate GApps package.
  • Open GApps (opengapps.org) is a popular choice. When selecting your GApps package, ensure you choose the correct architecture (ARM64 for the Poco F5), Android version (Android 16), and the desired variant (e.g., pico for a minimal set, nano, micro, full, etc., depending on your preference).
  • Alternatively, many users opt for MindTheGapps, which is often recommended by LineageOS developers for newer builds. You can find MindTheGapps on their official website or linked within the LineageOS device wiki.
• Transfer Files to Device: Once downloaded, transfer the LineageOS 23 ROM zip file and the GApps zip file to your Poco F5’s internal storage or a connected USB OTG drive. If you are unsure about transferring files while in TWRP, you can use ADB sideload.
