Hello, I'm trying to update my R4i Gold 3DS card with my ds lite so that it work on the 4.4.0-10U 3ds firmware. I put the NDSL.nds update file in the root of the sd card, and when I begin the update, it keeps saying Card Check Fail. I seen videos where the flash cart is removed when the the update file is booted, and then put again, but it keeps saying card check fail. I checked the other update file, NDSi.nds, and it also doesn't work. Does somebody know how a solution to this. My card is working because my brother plays games on his ds lite. I just want to play ds games on my 3ds.
