Hacking My R4i Gold stopped working all of a sudden

[Deleted User]

I was using my R4i Gold on my 3DS to play Pokemon Heart Gold, I had no problems with it at all until I decided to switch over to my DS Lite, the cart wouldn't boot at all. I also tried it in my 3DS again, but it wasn't able to boot the cartridge either, it looked like it was trying to, though. The screens turned white for a few seconds like it usually does when it boots up, but went back to black and it just sat there like that. I tried cleaning the cartridge contacts, that did nothing.
I have a video showing me trying to boot the cartridge on both my 3DS and DS Lite, I can upload it to YouTube if anyone wants to see it.

EDIT:

Please upload the video and have you checked the sd card?

Ok, I'll do that and I have no idea why I didn't think of that in the first place. I'll do that once I start uploading the video.

The card itself seems to be okay, the first time I tried to enter the _rpg folder, it told me that I had the wrong SD card in E:\, but the second time it opened up perfectly.
Also, I'll put the video in the OP once it's done.
