Our extraction method for the M4 file structure is currently incomplete, but our tools are sufficient for extracting apps. You will need scripts from Keitai Scripts on GitHub.

Step 1: assemble_m4.py

The assemble_m4.py will divide the regions of the nor dump

python assemble_m4.py <file name>.bin

Example

python assemble_m4.py N506i-2_PF38F4462LLYDB0-f1.bin

Step 2: convertForEmulator_m4.py

The convertForEmulator_m4.py script will extract the DoJa files from the regions inside the firmware dump.

python convertForEmulator_m4.py m4_out_dir model_name

Example

python convertForEmulator_m4.py N506i-2_PF38F4462LLYDB0-f1.bin_output N506i
