Sorry for the late reply, I needed to get some tools to be able to access the SSD on its own outside of the pod.
I do wonder what could be problematic part, the IC on the adapter board, the controller on the SSD, or just how they formatted it? (so purely software problem)
I'm wondering about alternatives and happened to find an M.2 sata to micro SD converter (Haven't bought yet). Assuming the problem could be with the SSD itself, do you think I would have better luck with that combination? I know its also kind of dodgy solution but the thing is, the official iflash boards are rather expensive where I live.
Other solution I'm considering is the ZIF to CF adapter, and CF to micro SD into that, altho thats similarly dodgy with running 2 adapters.
