Introduction
This is a dumping guide for
- Pre-Android/iOS Feature Phones
Recommendations
The preferred method for extracting data from feature phones is through USB. For most Docomo phones and select SoftBank phones, the best way to extract data is using the Foma Debug Adapter with ktdumper. The scripts in ktdumper are highly unlikely to brick your device, though we cannot guarantee that 100%.
The second best method is through JTAG using a tool like the Riff Box or JLink. This process requires basic soldering skills, and is mildly invasive to the phone depending on how easy it is to disassemble and reassemble. For phones that are confirmed to be compatible with these tools, we have included JTAG diagrams. Discovering JTAG points on your own requires specialized hardware such as a JTAGulator or JTAGenum.
The last method for extract data from feature phones is direct chip dump. This method is the most destructive of all, but is necessary for phones that cannot be exploited through USB or JTAG.

Operating System/File System/FTL Extraction Guides
Most extraction scripts are written in Python with some exceptions. Some tools are either Windows-exclusive or Linux-exclusive (compatible with WSL).
