Since this tool is designed for reverse engineering (decompiling/recompiling APK and JAR files) and is protected with PyArmor, some antivirus engines may flag it.

• Why? Bytecode manipulation and obfuscation are often flagged as "suspicious" by automated AI scanners.
• Is it safe? Absolutely. It is a clean utility for developers. Check the VirusTotal report below for full transparency.
• Note: If your antivirus deletes the file, add the tool's folder to the Exclusions list.

1. Download H-K-S_APK-JAR_TOOL_V3.0.zip from the download links below.
2. Extract the archive into a dedicated folder.
3. Launch H-K-S_APK-JAR_TOOL_V3.0.exe.
4. Open SETTINGS and click UPDATE BINARIES to download all necessary core components.

H-K-S APK-JAR Tool Extended incorporates, orchestrates, and builds upon the following essential open-source tools and frameworks:

• REAndroid APKEditor — REAndroid Developers (GitHub)
  APKEditor is a powerful command-line tool built on the REAndroid framework designed for parsing, modifying, decoding, and reconstructing Android APK, APKS, and split resource packages cleanly.
• Apktool — Connor Tumbleson (iBotPeaches) & Brut.all (GitHub)
  Apktool is a globally recognized tool for reverse engineering 3rd party, closed, binary Android apps. It can decode resources to nearly original form and rebuild them after making modifications.
• Apktool HKS-Mod — H-K-Systems (GitLab)
  Custom engineered Apktool variant featuring Native Expert Mode patch-map mechanics for deep resource decompilation and framework bypass capabilities.
• Smali / Baksmali — Ben Gruver (JesusFreke) (GitHub)
  Smali and Baksmali are an assembler and disassembler respectively for the dex format used by Dalvik and ART, the Android runtime engines. It implements the Jasmin/dedexer syntax.
• Bundletool Engine — Google Android Open Source Project (GitHub)
  Bundletool is the official underlying command-line tool used by Google, Android Studio, and Google Play Console to manipulate Android App Bundles (AAB), generate split APK sets, and deploy them to target hardware devices.
• NanaZip Utility — M2-Team (Website)
  NanaZip is free software with open source based on 7-Zip. It provides high compression ratios and robust archive integrity extraction arrays.
• AAPT / AAPT2 Engine — Google Android Open Source Project (Android Dev)
  Android Asset Packaging Tool (AAPT/AAPT2) is an official compilation engine parsed by Google daemon pipelines to compile, optimize, and link Android resources into highly structured binary tables.
• AAPT2 HKS-Mod Engine — Google AOSP & H-K-Systems (GitLab)
  Custom modified AAPT2 binary patched to resolve framework resource collisions and bypass strict compilation errors during complex APK rebuilding.
• Apksigner Tool — Google Android Open Source Project (Android Dev)
  Apksigner is a dedicated signing engine designed to cryptographically sign Android APK packages and verify that their digital signatures will pass verification security checks on all Android platforms.
• Zipalign Tool — Google Android Open Source Project (Android Dev)
  Zipalign is an archival alignment utility that ensures all uncompressed data within an Android application package (APK) aligns perfectly to specific 4-byte boundaries, significantly reducing runtime RAM overhead.
• AOSP Security Keys — Google Android Open Source Project (Android Dev)
  Official open-source Android Platform build security certificates (including testkey, platform, shared, and media matrices) extracted directly from AOSP build tree specifications to process cryptographic package handshakes.
• JAVA (JRE) — bell-sw Liberica JRE (Website)
  Liberica JRE – a free, supported, and full open-source distribution of OpenJRE, verified by TCK for Java SE. Liberica JRE binaries are free for all users, including commercial and production usage.
• PySide6 Framework — The Qt Company (Website)
  PySide6 is the official Python module from the Qt Company, providing LGPL-compliant bindings for the Qt v6 framework to power the graphical user interface.
• Python Runtime — Python Software Foundation (Website)
  Python is an interpreted high-level programming language providing the underlying core backend architecture, process orchestration, and multithreaded execution pools.

• Tools: Samsung Odin (for flashing the result)

Due to the nature of Android engineering tools (bytecode manipulation, boot image patching, and executable packing with PyArmor), some antivirus engines may flag these files as "Generic" or "Malicious".

• Why? The code is obfuscated to prevent tampering, and the tool performs low-level system image modifications.
• Is it safe? Yes. These are 100% false positives common for reverse engineering utilities. If you are in doubt, you can run the tool in a Virtual Machine or Sandbox.

1. Download H-K-S_Magisk_Avbtool_Patcher.zip from the link below.
2. Extract the ZIP archive fully into a dedicated folder (it contains the exe, bin folder, and all dependencies).
3. Launch H-K-S_Magisk_Avbtool_Patcher.exe from the extracted folder.
4. Select your AP firmware (.tar.md5) and optionally add TWRP (.img).
5. Click Start Patching and find your ready-to-flash .tar in the output folder.
