How to unpack android rom img files Android14 boot.img system.img

Unpacking Android ROM .img files, such as system.img, boot.img, or vendor.img, typically involves specialized tools and steps. Below is a step-by-step guide for unpacking Android 14 ROM .img files:

---

Step 1: Identify the IMG File Type​

• Sparse Image: Many .img files in Android ROMs are in a "sparse" format, requiring conversion to a "raw" format before unpacking.
• Raw Image: These can be directly mounted or extracted.
  
  

• Step 2: Tools You’ll Need​

  1. Linux Environment (Ubuntu, WSL, or macOS preferred).
  2. Android Kitchen Tools:
     
     • simg2img (for sparse to raw conversion).
     • ImgExtractor or tools like Carliv Image Kitchen for boot.img files.
  3. Mounting Tools:
     
     • mount command (Linux) or DiskImageMounter (macOS).
  4. ADB and Fastboot Tools: Download here.

  Step 3: Convert Sparse IMG to RAW (If Needed)​

  1. Download and compile simg2img:
     bash
     Copy code
     sudo apt update
     sudo apt install git gcc make
     git clone https://github.com/anestisb/android-simg2img.git
     cd android-simg2img
     make
  2. Convert the sparse image:
     bash
     Copy code
     ./simg2img system.img system.raw.img

• ---

  Step 4: Extract or Mount the RAW IMG File​

  • Extract with 7z:
    bash
    Copy code
    7z x system.raw.img -ooutput_directory
  • Mount with Linux:
    bash
    Copy code
    mkdir system_mount
    sudo mount -o loop system.raw.img system_mount

• ---

  Step 5: Extract boot.img or recovery.img​

  For files like boot.img or recovery.img, you need a tool like abootimg or Android Image Kitchen:
  
  1. Install abootimg:
     bash
     Copy code
     sudo apt install abootimg
  2. Extract the contents:
     bash
     Copy code
     abootimg -x boot.img
  3. Use Android Image Kitchen for a GUI-based alternative.

  Step 6: Analyze the Files​

  • Extracted files often include:
    
    • System files (e.g., bin, lib, etc, build.prop).
    • Kernel and ramdisk (from boot.img).
  • Modify or inspect the files as needed.

  • Magisk (for customizations like rooting).
  • AIK (Android Image Kitchen) for detailed boot image modifications.
