A guide on how to update your vendor tree blobs from stock ROM

• Vendor Blobs are purely based on proprietary-list.txt included in the device tree used in extracting.
• It maybe edited or not edited.
• Device and vendor names might different from what the device itself says.
  • So I will be putting the device name in the description area just to be clear.

• Dumpyara
• Aospdtgen
• DumprX
• AndroidDump
• LineageOS
  • Extract-Tools
  • Extract-Utils

• Dump a Firmware using dumping tool/script of your choice like Dumpyara, DumprX..etc.
• Change directory to the rom source
• Clone neccessary tools/scripts inside the rom source directory - most lineage based roms have these two repos cloned already:

     git clone https://github.com/LineageOS/android_tools_extract-utils -b lineage-22.2 android/tools/extract-utils
     git clone https://github.com/LineageOS/android_prebuilts_extract-tools -b lineage-22.2 android/prebuilts/extract-tools

• Clone or Copy/Move your Existing Device Tree inside device/vendorname/codename directory if not already cloned.
  • If you don't have yet, use aosptdtgen to generate device tree.

• Directory should be look like this: for sh script

   - rom_source/
       - device/
           - vendorname/
               - devicecodename/
       - android/
           - tools/
               - extract-utils/
           - prebuilts/
               - extract-tools/

• Inside you device tree folder, run:

./extract-files.sh /path/directory/to/your/rom_dump/

• same structure as above of path
• if you use paython script then do this:
• define tool path PYTHONPATH=../../../tools/extract-utils

chmod a+x extract-files.py
./extract-files.sh /home/mayuru02/d/out

• Wait until finished. You'll find the blobs under android/vendor/vendorname/codename
