Okay, so I sent my AceKard to a friend of mine when it was disabled for use on the Nintendo 3DS, and I love my 3DS and know how Nintendo is trying to stop piracy 100%, and I don't want to risk bricking my 3DS. But ANYWAYS, I sent it to my friend, it's an AceKard2i, it was completely up to date and loaded with a few games they requested, and the 'up-to-date' was at the time there before the Nintendo 3DS System Update that added things such as the Internet Browser and eShop and all that. That's where they disabled it. And that's the firmware it was on. But no, randomly, it stopped working on my friend, and they keep getting the "System Files Not Found" error anytime they try to start it up. I've had them format the card and replace the system files, try putting update files on there and such, but nothing seems to work. Is it possible the AceKard is broken? Or the MicroSD card maybe? Any tips and pointers will be very much appreciated, from me, and my friend. They're waiting on their brother to get home with his AceKard right now and try to copy the system files from there to their SD card and see if that works right now. We're gonna see how that goes. But I just want to see if it can be solved before then. Thanks a ton!
