Bug description | 描述 Bug

After patching my stock boot.img using APatch CLI tools (kptools-linux + kpimg-android + magiskboot), the device always enters a bootloop after flashing the patched image. I followed the official documentation step by step, and the patch process completes successfully without errors, but the system cannot boot afterward

Reproduce method | 复现方法

Extract boot.img from Pixel Experience ROM (Android 13).

Run magiskboot unpack boot.img.

Rename the kernel to kernel-b.

Run the following command:

./kptools-linux -p --image kernel-b --skey "iyad2013" --kpimg kpimg-android --out kernel

Run ./magiskboot repack boot.img to generate new-boot.img.

Flash with fastboot:

fastboot flash boot new-boot.img

Device reboots into bootloop.

Expected behavior

Device should boot normally with APatch root active (visible via Apatch Manager or shell).

Actual behavior

Device immediately reboots into a bootloop after flashing the patched image.

Other information | 其他信息

Magisk was previously installed, but removed before flashing.

Verified kernel supports CONFIG_KALLSYMS=y.

Tried both direct flashing and repack methods.

Bootloop occurs even after wiping caches and reflashing stock boot before patching.

SuperKey used: iyad2013.

Device enters bootloop right after showing boot logo.
