This article details an issue experienced while attempting to patch a Google Pixel 6a running Android 16 (BP22.250221.013) using Magisk 28.1. After patching the boot.img file and flashing it to the device, the system entered a persistent boot loop displaying the Android Recovery screen.

The following steps were taken to reproduce the issue:

1. Downloaded the official Android 16 factory image and verified its hash.
2. Extracted the image file using 7-zip.
3. Transferred the oot.img file to the Pixel 6a using Google Quick Share.
4. Patched the boot.img using Magisk 28.1.
5. Transferred the patched boot.img back to the computer.
6. Rebooted the device into bootloader mode using ADB.
7. Flashed the patched boot.img using fastboot.
8. Rebooted the device.

Following the patch and flash, the device was unable to boot past the Android Recovery screen, resulting in a boot loop.

To resolve the issue, the original, unpatched boot.img file was flashed back to the device, allowing it to boot successfully.

The expected outcome was a successful boot into the Android system after flashing the patched boot.img.

This issue suggests a potential incompatibility between Magisk 28.1 and the Android 16 build on the Google Pixel 6a, or a flaw in the patching process.
