R4 not working in version 11.13

For context, I've had this cart for a long time, and it worked perfectly until I updated my 3ds.
The cart itself is an R4 infinity, it doesn't list 3ds support but before I updated it worked just fine on it.
The 3ds is just a standard 3ds that I modded, which is the only reason I updated in the first place, the specific version it's on is 11.13.0-45E, if that helps for anything.

When I boot up the 3ds, everything works as it normally does, but when I insert the cart, the custom theme's music stops, and then after a few seconds it just freezes completely. I tried just taking out the SD to see if it would work, but nothing, I did somehow manage to get it to read the cart (with the SD inserted), but it just showed a solid white box in the card, and trying to actually load it just showed an error screen saying to turn off the 3ds.

I hope this is enough info for someone to help, I'm new here so I just listed everything that seemed relevant.

 

I think the kernel may not be up to date, and I don't know which firmware you mean, I'm still kinda new to this stuff and don't really know where to check either

 

ok, from the page I can then tell that I do actually have the latest version (I have infinity 3) since I actually did have to try to restore the cart once, sadly it doesn't list support for 11.x.

 

probably one of the earliest, (1.6-ish?), I updated I believe on october last year (or a bit earlier), and I hadn't tried to use the cart until today, so, that's why I'm not on the latest version
.
This isn't actually my main 3ds, if you were wondering why the version was so outdated, I do have another one since I accidentally got the EU one (this one) while I was in the americas, meaning I couldn't play any US version games I bought.
I updated on the same day I started modding the 3ds, as well, just thought I'd put that out there.


I'd rather not get into unnecessary details involving why I got the EU one instead of the US one, as I don't want to stray off the main topic.

 

Just tried opening through GodMode9, it crashed, it showed "0 bytes" but after testing it out with a regular game cart it seems that it does this anyways.
Removing the micro SD still crashes it so I guess it might actually be defective. Is there anything I could do from here? (apart from getting another cart)

 

It doesn't crash with the legit game, it's only the 0 bytes thing, and it did correct itself after opening [C:], opening it with the flashcart does crash it, however.

I am running Luma, I just don't know what to do with it.

 

That seemed to fix it, I guess it was just really dusty, I did try cleaning it a bit before, but I guess I didn't clean it thoroughly enough.
Thanks for all the help.
