sleep mode not working on my flashcart?

[kbf]

It seems like it's doing the same thing that my EZ flash paralell was doing. I got my kernel from here https://sanrax.github.io/flashcart-guides/cart-guides/bl2ck/
As for the cart itself I think it was this one: I show 2 links because the one with no label's store link page 404's and as for the other one I can't recall if that's the one I never received in the mail, and if that was also suppose to be a cart with no label despite the picture having one.

Yours is an R4DS Pro. I do not recommend these as they're known to be very unreliable and easily brick. I suggest you ask for a refund then swap it for an Ace3DS+ / X or R4i-SDHC timebombed clone.
