Hi, I have bought a Samsung PROplus 256GB card for use with the newly purchased Model 2400, which is on Tascam's approved list (unless I am missing some versioning that I am not aware of - A2, v30, 4k). The unit says "Invalid card Change card" but I am also aware that the firmware needs updating (from 1.00 to 1.01), which could affect reading of the sd card. However, to update the firmware, I need to insert an sd card. I don't want to buy another card if not necessary (and potentially a wrong one again???). How best can I resolve this loop please? How do I update the firmware without being able to read the sd card?
