Ktdumper
Ktdumper is a tool for extracting data from feature phones that are compatible with the Foma debug adapter, which includes all Docomo phones and select SoftBank phones. Please note that ktdumper will not work unless you have the Foma debug adapter.
Ktdumper is compatible with Linux and WSL (Windows System on Linux). It can be used as a command line tool or as a live Linux iso with a GUI.
Ktdumper Command Line
- Make sure your phone is connected to the PC (if using WSL, you will need to bind your USB device)
- Download the ktdumper repository from Github
- Navigate to the main ktdumper folder, where the code will be executed.
- You can execute the following commands
- NAND (contains user data, downloads, etc.)
sudo ./ktdumper.sh [insert phone model] dump_nand
- NOR
sudo ./ktdumper.sh [insert phone model] dump_nor
- JAVA Folder (only works on select Mitsubishi/Fujitsu phones)
sudo ./ktdumper.sh [insert phone model] dump_java
