OnePlus Open Kernel Patcher

Automated Magisk patching for OnePlus Open firmware. This repository automatically checks for new firmware releases daily, downloads them, extracts the boot image, patches it with Magisk, and publishes the patched images as GitHub releases.

Quick Start

Download the latest patched boot image from the Releases page and flash it:

# Boot into fastboot
adb reboot bootloader

# Flash the patched image
fastboot flash init_boot magisk_patched_init_boot.img

# Reboot
fastboot reboot

Then install the Magisk app on your device.

How It Works

A GitHub Actions workflow runs daily to:

1. Check for new OnePlus Open (India) firmware via the OxygenOS Updater API
2. Download the firmware if a new version is available
3. Extract payload.bin from the firmware ZIP
4. Extract init_boot.img, boot.img, and vendor_dlkm.img from the payload
5. Patch the boot image with the latest Magisk
6. Create a GitHub release with stock and patched images
