Most Docomo FOMA phones are compatible with a FOMA debug cable/adapter. The main exception is Motorola, who kept using mini-USB. The file dumping process for these phones is relatively straightforward, but there are a few things to keep in mind:
Some phones make inaccurate dumps with WSL and require an actual Linux computer instead (particularly late NEC)
Current file extraction tools are split between Windows and Linux, though all Linux extracting tools can be used with WSL
