I had a really cheap maybe fake R4 that I got from ebay which I finally managed to get working after locating the right firmware files.
I successfully used the NTR flash method to hack another 3ds I had laying around.
After flashing the card back to normal I end up getting a "FAKE CARD RETURN TO RETAILER" message when my cart tries to load now.
I fear I may have overwrote the original back up with the R4SDHC one from https://hax.b4k.co/3ds/guide?p=installing-boot9strap-(ntrboot)...
May have ruined my card after a NTR flash..
