Sony Ericsson were only manufactured in the early era of Docomo Foma phones. The series begins at 902i/702i and ends at 906i/706i. Note that there is no SO904i.

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 that for early Sony Ericcson phones, all data is in the NOR, and there is no NAND script.
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.
EPOC32 is a mobile operating system. It is a predecessor to Symbian, and its data can be extracted using tools from the Symbian 3 SDK.
C:\Nokia\devices\Nokia_Symbian3_SDK_v1.0\epoc32\tools\readimage.exe
Put the dump into the same folder as readimage.exe
.\readimage.exe <file name> -z <output folder name>
This script will create an output folder and place all files inside of it.
NOTE: For Sony Ericsson phone NOR dumps, you may need to cut out the data before 0x100000
TestDisk can be used on either Windows or Linux. It is available for download here. Once you have downloaded TestDisk, use the program to open your current .bin file.
>Disk <your file>
Press enter to proceed.
[None ] Non partitioned media
[ quit ]
[ Analyse ]
[Quick Search]
You should now have all the extracted files.
Note: For select devices (such as F905i and D905i), you need to select None → Undelete rather than the usual TestDisk procedure.
Once you've dumped your games, it's time to generate and submit metadata to a preservation project for validating and cataloging. See the dump submission instructions for more information.
