Patch boot.img Manually (magiskboot)
[!CAUTION]
Wild Kernels is not responsible for bricked devices or damage. By flashing, you assume all risk. Back up your data and understand the risks before flashing.
[!TIP]
It's always recommended to use magiskboot to patch images — use the official build, which runs on Android devices and Linux.
Platforms: Android · Linux
Preparation
- Get your device's stock
boot.img.
- Download the AnyKernel3 ZIP file that matches your kernel version (e.g.,
6.1.x-androidXX).
- Unpack the AnyKernel3 package and get the
Image file, which is the kernel file of KernelSU.
[!NOTE]
Match by the full kernel version (e.g., 6.1.x-androidXX) — your device's Android version and the androidXX in the kernel version are not necessarily the same. For example, as of writing, a Google Pixel 8 is on 6.1.157-android14 while the system Android is 17.
Android — via adb + libmagiskboot.so
Folder structure on device (`/data/local/tmp/`):
```
/data/local/tmp/
├── magiskboot
├── boot.img
└── Image
```
1. Download latest Magisk from [GitHub Releases](https://github.com/topjohnwu/Magisk/releases).
2. Rename `Magisk-*(version).apk` to `Magisk-*.zip` and unzip it.
3. Push `libmagiskboot.so` to your device by ADB:
```sh
adb push Magisk-*/lib/arm64-v8a/libmagiskboot.so /data/local/tmp/magiskboot
```
4. Push stock `boot.img` and `Image` from AnyKernel3 to your device:
```sh
adb push boot.img /data/local/tmp/
adb push Image /data/local/tmp/
```
5. Enter ADB shell and make it executable:
```sh
adb shell
cd /data/local/tmp/
chmod +x magiskboot
```
6. Unpack `boot.img`:
```sh
./magiskboot unpack boot.img
```
You will get a `kernel` file — this is your stock kernel.
7. Replace the kernel with the KernelSU `Image`:
```sh
mv -f Image kernel
```
8. Repack the boot image:
```sh
./magiskboot repack boot.img
```
You will get a `new-boot.img` file.
9. To temporarily test you can run `fastboot boot new-boot.img`.
10. Flash it by fastboot:
```sh
fastboot flash boot new-boot.img
```
Linux — official magiskboot
Folder structure on PC:
```
.
├── magiskboot
├── boot.img
└── Image
```
Official `magiskboot` can run in Linux normally — use the [official build](https://github.com/topjohnwu/Magisk/releases).
1. Prepare stock `boot.img` and `Image` in your PC.
2. Make it executable:
```sh
chmod +x magiskboot
```
3. Unpack `boot.img`:
```sh
./magiskboot unpack boot.img
```
You will get a `kernel` file — this is your stock kernel.
4. Replace the kernel:
```sh
mv -f Image kernel
```
5. Repack:
```sh
./magiskboot repack boot.img
```
You will get a `new-boot.img` file.
6. To temporarily test you can run `fastboot boot new-boot.img`.
7. Flash it by fastboot:
```sh
fastboot flash boot new-boot.img
```
