1. Download the b4-ftl-extract scripts from Github
2. Place scripts in the same folder as nand.bin
3. EITHER drag nand.bin into b4b4.bat or enter the following command

   python extract.py -s nand.bin output_dir

   This code will unscramble the FTL and place all data into a folder called output_dir

After this, you must use TestDisk to acquire the data.
