Docomo Phones by Sharp

Check the dumping hardware overview for a list of known preservation hardware.

If you need help, please come chat with us on the Keitai World (previously Keitai Wiki) discord server.

Sharp Docomo phones generally run on a customized version of Symbian. These phones will not light up when plugged into a debug adapter.

Many of these phones keep their DoJa games in a unique file format made up of a .apl and a .scp. To extract files in this format, use Keitai Tools.

Notes on specific phone models:

• SH-05A/SH-06A: These two phones have multiple dumping settings. If the primary dumping settings do not work, use the v2 settings in ktdumper. The command should look like this:

sudo ./ktdumper.sh sh-05a.v2 dump_nand

NOTE: For USB dumpable phones before the SH903iTV, you must use either a regular foma usb cable or a debug usb cable with the power turned off, and the phone must be powered on with battery or an external power supply.

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

sudo ./ktdumper.sh d904i dump_nand

First, you must download the Various Keitai Assemble GitHub repository. We will be using the assemble_f0.py script as well as the tools in the utils folder.

The nor for this dump comes in two parts that need to be concatenated.

Examples:
Windows Command Line

copy /b SH700iS_LRS13B7-f1.bin + SH700iS_LRS13B7-f2.bin SH700iS_LRS13B7-f1f2.bin

Copy the concatenated file into the various-keitai-assemble project. The following steps will be different depending on what device you are trying to extract. The end result of all options will be an output directory with many .bin files. Look for the largest one and use TestDisk to acquire the data. You may need to use UNDELETE.

Note: If the following settings do not work, make sure to do a byteswap.

J-Phone

  J-SH07: 5504
  J-SH08: 5504
  J-SH010: 6355
  

Vodafone

DoCoMo

python assemble_f0.py -u -b 9 SH700iS_LRS13B7-f1f2.bin SH700iS_LRS13B7-f1f2_out

Before using assemble_sh704i_d904i.py, you must separate the NAND and OOB (out of bounds) data.

1. Download the separate_nand_oob.py script from Github and place it into the folder generated by ktdumper
2. Execute the following script

   python separate_nand_oob.py nand_mixed.bin

3. When given a set of options, select 0 (the other options are not needed for D904i/SH904i devices)

   0: Data = 512 Bytes, OOB = 16 bytes, divisible = True

To remove the FTL:

1. Download the assemble_sh704i_d904i.py script from Github
2. Execute the following command

   python assemble_sh704i_d904i.py nand_mixed_separated_512.bin output.bin

After this, you must use TestDisk to acquire the data.

NOTE: If TestDisk cannot extract the data, try selecting the [UNDELETE] option rather than the [Analyze] option.

1. Download the assemble_sh900i.py script from Github
2. Execute the following command with your dump-specific variables

   python assemble_sh900i.py <input file> <output file>

After this, you must use TestDisk to acquire the data.

First, you must download the Various Keitai Assemble GitHub repository. We will be using the assemble_sh902i.py script as well as the tools in the utils folder.

Concatenate all pieces of the file.

Examples:
Windows Command Line

copy /b SH700iS_LRS13B7-f1.bin + SH700iS_LRS13B7-f2.bin SH700iS_LRS13B7-f1f2.bin

Copy the concatenated file into the various-keitai-assemble project. Then use the following command:

python assemble_sh902i.py <concatenated_dump>.bin output_dir

1. Download the b4-ftl-extract scripts from Github
2. Place scripts in the same folder as nand.bin
3. EITHER drag nand.bin into b4b4.bat or enter the following command

   python extract.py -s nand.bin output_dir

   This code will unscramble the FTL and place all data into a folder called output_dir

After this, you must use TestDisk to acquire the data.

NOTE: If TestDisk says that the partition(s) can't be recovered, try [UNDELETE] instead of Analyze.

Fugue Nand Regular

1. Download the fugue-tools repository from Github
2. Place extract.py from fugue-tools into the same folder with nand.bin and nand.oob. Run this command:

   python extract.py nand.bin output.bin

The file system can now be read and extracted with TestDisk.

Fugue Nand A+B

1. Rename the files in the Part A dump folder to nand_a.bin and nand_a.oob
2. Rename the files in the Part B dump folder to nand_b.bin and nand_b.oob
3. Place all of these files into the same folder along with extract.py from fugue-tools.
4. Execute the following command

   python extract.py nand_a.bin nand_b.bin output.bin

The file system can now be read and extracted with TestDisk.

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.

1. Install the Symbian SDK (Windows)
2. Find readimage.exe. In a typical Symbian 3 SDK install, it will be located here.

   C:\Nokia\devices\Nokia_Symbian3_SDK_v1.0\epoc32\tools\readimage.exe

   Put the dump into the same folder as readimage.exe

3. Open the command line in that folder and paste the following:

   .\readimage.exe <file name> -z <output folder name>

   This script will create an output folder and place all files inside of it.

Example

.\readimage.exe dump_nor.bin -z output_dir

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.

1. When you open a .bin file with TestDisk, you will have the option to select a media. There should only be

   >Disk <your file>

   Press enter to proceed.

2. When asked to select a partition table type, select None

   [None ] Non partitioned media

3. On the following page, press q to quit or select

   [ quit ]

4. In the new menu, move up the menu and select

   [ Analyse ]

5. Press enter to continue with

   [Quick Search]

6. You should now see a partition labeled with a file system like FAT16 or FAT32. Don’t press ENTER. Instead, press p to list files.
7. Press a to select all files.
8. Press C (note the capitalization and hold the shift button!) to copy the selected files.
9. Choose the output folder. Press C when the folder is correct.

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.

Keitai Tools is a python tool for extracting valid DoJa files from a variety of phone file systems.

1. Download keitai-tools from GitHub
2. Copy the top level java folder into the keitai-tools project. NOTE: This folder has different names on different devices including “java,” “javaap,” and “LIST” Choose the lowest possible folder that still contains all java apps in subfolders.
3. Use the following command, changing the name of the folder based on the phone that you have

python kttools.py top_folder_directory

Example: For F-03B, the top folder directory is “Java”

python kttools.py Java

SPECIAL INSTRUCTIONS FOR EARLY FUJITSU PHONES

Early Fujitsu phones often lack .jam files. These files need to be recreated by Keitai Tools. To recreate the .jam files, you will need to set up the environment with the following commands

For Windows:

python -m venv venv
venv\Scripts\activate.bat
pip install construct scsu

For Linux:

python3 -m venv venv
source venv/bin/activate
pip install construct scsu

After setting up the environment, you can proceed with Step 3 above.
