Tascam Model 2400 SD card not valid and/or firmware needs updating?

[Major777]

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?

Welcome to the community, @Major777.

I think this catch 22 issue came up once before, about a year ago. A "firmware" search on this subforum should find the thread.

EDIT
@Major777 I see you logged in again a few hours after I responded to you. Did you find the thread, and did it help solve the problem?

If not:
The approved list is dated 10/01/25 and shows both 128gb and 256gb for the Samsung Proplus. The Model 2400 was released in July 2024. It could be that the initial firmware version only supported 128gb.

Try a new search on "invalid card".
