Softbank 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.

Softbank Sharp phones are actually quite different from their Docomo Sharp counterparts. While they share the same FOMA port as the Docomo Sharp phones, they have a different CPU with a different bootloader. Currently, we have no means of extracting data from these phones outside of direct memory chip dumping. However, that could change if someone is able to discover an exploit in the bootloader.

The firmware examples we have appear to use a Flat file system alongside a FlashFX 4.00 FTL, for which there is no documentation.

Reading File Systems

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.

Known chunk IDs per model:

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

SH506iC

Default settings work fine for this phone

python assemble_f0.py <concatenated_dump>.bin output_dir

SH700iS/SH901iC/SH901iS

Command:

python assemble_f0.py -u -b 9 <concatenated_dump>.bin output_dir

Example:

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

The output directory will contain many .bin files. Look for the largest one and use TestDisk to acquire the data. You may need to use UNDELETE.
