Panasonic Docomo phones generally run on a customized form of Linux. They use a bootloader related to the one used in NEC and Casio Docomo phones. When a Panasonic phone is properly connected to a debug cable, it will light up for approximately one second, and then turn off.

Extracting Data
Reading File Systems
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.
sudo ./ktdumper.sh [insert phone model] dump_nand
sudo ./ktdumper.sh [insert phone model] dump_nor
sudo ./ktdumper.sh [insert phone model] dump_java
Sample For D904i
sudo ./ktdumper.sh d904i dump_nand
WIP
NOTE: This extraction method may not work on WSL. If you are having errors after trying all steps, try switching from WSL to a full Linux installation.
sudo apt install gcc-arm-linux-gnueabi pip3 install qiling
arm-linux-gnueabi-gcc -static -omain fsr.ko fsr_stl.ko main.c
python3 emu.py
Current tools for removing the SSR200 FTL are meant to work on Linux or WSL (Windows Subsystem for Linux)
sudo apt-get install python3-pip sudo pip3 install pyfatfs
chmod +x install.
Then run install.sh
sudo ./install.sh
The following steps are different based on whether you are trying to extract SSR200 or SSR200 “Old Flavor”
Regular SSR200
python3 run.py nand.bin
SSR200 “Old Flavor”
sudo apt install sleuthkit
run.sh nand.bin
Current tools for extracting XSR1 require Windows.
.\rfs_dumper.exe input.bin output.bin
The file system can now be read and extracted with TestDisk.
NOTE: This extraction method may not work on WSL. If you are having errors after trying all steps, try switching from WSL to a full Linux installation.
sudo apt install gcc-arm-linux-gnueabi qemu qemu-user-static qemu-system-arm
arm-linux-gnueabi-gcc xsr_stl.ko main.c -o main
export QEMU_LD_PREFIX=/usr/arm-linux-gnueabi ./main onenand.bin onenand.oob B output.bin
export QEMU_LD_PREFIX=/usr/arm-linux-gnueabi ./main onenand.bin onenand.oob A output.bin
export QEMU_LD_PREFIX=/usr/arm-linux-gnueabi ./main onenand.bin onenand.oob 8 output.bin
After this, you must use TestDisk to acquire the data.
The JFFS2 file system can be extracted with Jefferson, which runs on Python. You can install Jefferson in a pre-existing Python using pip:
sudo apt-get install python3-pip sudo pip3 install jefferson
The following command creates a folder called “jffs2_extracted” to contain the data extracted from nand.bin.
sudo jefferson -d jffs2_extracted nand.bin
Note: You may see the error
data_crc does not match!
The dump may still be working. Let it continue until the process is complete before trying other steps.
Troubleshooting
If the jffs2_extracted folder contains no data, the offset will need to be removed from the .bin file.
You can determine the offset two ways:
binwalk nand.bin
85 20 19 E0
Or
85 19 02 E0
Delete all data before those four bytes and try again to extract with Jefferson.
Note: It is not possible to undelete files from a JFFS2 file system.
