Our extraction method for the M4 file structure is currently incomplete, but our tools are sufficient for extracting apps. 

**Step 1:** [[https://github.com/ZiplineGun/k/blob/main/assemble_m4.py|assemble_m4.py]] ([[https://github.com/Keitai-Archive/Keitai-Scripts/blob/main/BeforeExtraction/assemble_m4.py|backup link]])

The assemble_m4.py will divide the regions of the nor dump. Use the ``-r`` argument to extract specific files based on the phone model. 
<code>python assemble_m4.py  -r <phone model><file name>.bin</code>
Example
<code>python assemble_m4.py -r N506i N506i-2_PF38F4462LLYDB0-f1.bin</code>

**Step 2:** For DoCoMo phones ONLY: [[https://github.com/ZiplineGun/k/blob/main/convertForEmulator_mova_nec.py|convertForEmulator_mova_nec.py]] ([[https://github.com/Keitai-Archive/Keitai-Scripts/blob/main/PostExtraction/convertForEmulator_mova_nec.py|backup link]])

The convertForEmulator_mova_nec.py script will convert the appli in the JAVA folder into a format usable by DoJa emulators. 
<code>python convertForEmulator_mova_nec.py <java_folder> model_name</code>
Example
<code>python convertForEmulator_mova_nec.py JAVA N506i</code>
