R4 SDHC Gold Pro not recognized
Edit: I think it may just be a broken/faulty card considering it was an Amazon return item, returner may have pulled a swapero on this. Will try any other suggestions but I'm not worried about it.
Bought this today from a return site and can't seem to figure out what's going on. It would not be recognized by my 3ds with Luma or my DSi. I have another flashcart, am R4i+ with NTR boot switch inside and I used that a long time ago to homebrew the 3ds. Since it had a switch I never dealt with refreshing firmware back to it.
I tried setting back the time but since it's not being recognized at all to load I don't think that would help at all. I then tried downloading the rhisdhc.com v4.3 kernel from sanrax.github.io/flashcart-guides/r4i-sdhc and put that onto the SD card, still nothing.
At this point I'm wondering if the cart was flashed and then returned since it wasn't working anymore as there were already ROMs on the SD card. I went to 3ds.hacks.guide/installing-boot9strap-(ntrboot).html#section-v-removing-ntrboot and followed the steps there.
On the 3ds SD card, I copied:
ntrboot_flash.firm (v0.5.0) to /luma/payloads/
r4isdhc-backup.bin (from R4iSDHC.com_20XX-Flashrom.zip) to /ntrboot/
Reinserted the flashcart and SD card into 3ds, booted ntr_bootflasher, and tried to select R4iSDHC family, R4i Gold 3DS, and even DSTT but all of them say "Your flashcart is not supported."
Could this be a contact issue then or is this a fake card? Also don't mind the tape on the micro SD card, the flash carts micro SD cart slot doesn't keep the card in place and was already on the SD card when I bought it. I also thought I saw another post mentioning those 2 .DAT files being an indicator of what card I have but now I can't find it.
