Magisk Bootloop Issue on Pixel 6a: A Troubleshooting Guide

This guide addresses a common issue reported by users attempting to flash a patched boot.img on the Google Pixel 6a (Android 16 BP22.250221.013) using Magisk version 28.1. Utilizing Magisk to modify the boot image allows users to gain root access on their Android devices. However, in this specific instance, flashing the patched boot.img leads to a bootloop, preventing access to the Android system.

**Steps to Reproduce:**
1. Download the Android 16 BP22.250221.013 factory image from the official Google Developer website and verify its hash.
2. Decompress the factory image file using a tool like 7-zip.
3. Transfer the boot.img file from your computer to your Pixel 6a using a method like Google Quick Share.
4. Patch the boot.img file using Magisk version 28.1.
5. Transfer the patched boot.img back to your computer.
6. Connect your Pixel 6a to your computer and reboot into the bootloader using the command `adb reboot bootloader`.
7. Flash the patched boot.img using the command `fastboot flash boot PATH_TO_MY_BOOT.IMG`, replacing `PATH_TO_MY_BOOT.IMG` with the actual path to the patched file.
8. Reboot your device using the command `fastboot reboot`.
9. Upon reboot, your device will display the Android Recovery screen, preventing you from accessing the Android system.

**Troubleshooting:**
While troubleshooting a Magisk bootloop requires advanced knowledge of Android and bootloaders, some initial steps include:
* Double-checking Magisk version compatibility with your device and Android version.
* Ensuring the factory image and boot.img are valid and unmodified.
* Reinstalling Magisk and trying the patching process again.
* Seeking assistance from the Magisk community forums or developers.

**Note:** Modifying system files like the boot image can potentially void your device warranty and lead to instability. Always proceed with caution and make sure you understand the risks involved.
