Report: system-arm64-ab.img.xz — Android 12

1. Architecture: ARM64

Run uname -m in a terminal or check your device specs. If you have a 32-bit-only device (very rare after 2018) or an Intel x86 Android device (e.g., some tablets), this image will not work.

8. The Future: Android 12L and 13

For Android 12L (12.1) and Android 13, the naming scheme remains identical: system-arm64-ab.img.xz. However, newer images may include Virtual A/B (where even the super partition is dynamic). In that case, you would flash to super rather than system: system-arm64-ab.img.xz android 12

fastboot flash super system-arm64-ab.img
