Hi everyone. I have a somewhat unusual case involving a 2 GB microSD from which I’m unable to get good readings. I’ll attach some screenshots of the dump. I managed to identify WP, but the reading problem persists.

The Read ID I’m getting is EC D5 94 76 54.

While searching for information, I found that Arvika worked on what seems to be a very similar case. In his database, it appears as microSD #65, also 2 GB, Samsung, ID EC D5 94 76, controller EN2683, Page Structure 1075_26, and XOR FF09FD (DA) + GRID (full page).

There is also the following note:

“2x15, remove grid, make ECC, than XOR”

I have never worked with GRID (full page) before, so I’m not sure exactly how to identify or remove it. I’m hoping this may be what I’m missing and could explain why I’m unable to obtain a properly readable/interpretable dump.

Has anyone worked with this type of GRID in VNR, especially with the EN2683 controller, and could give me some guidance on how to identify and remove it?
