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.
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.
