Hey @lamda I’m sorry you’re continuing to have this issue, and I assume we tried reflashing the MicroSD card again?
Out of curiosity what kind of SSD are you using, is it an external one or is it an internal one that plugs inside an enclosure first then into your Pi 4? Sometimes I’ve seen a quick fix to be replace the cable, try a different USB 3.0 port, or replace the enclosure that could save you some time…
