??
i have multiple consoles
one that had all the Gateway Files
one that had all the R4i Gold 3DS Deluxe ones
swapped them after the R4i Gold 3DS Deluxe didnt work on one
and the Gateway Worked on the other with the Gateway Files
but the one the Gateway was working on didnt work with the R4i Gold 3DS Deluxe
I mean go into ds mode with r4 cart and use their installer for the exploit. You probably did, just making sure.
Have you tried the firmware on the 3dslink page? They should be the same thing, but who knows.
