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
