Hacking O3DS RX tools R4 Flashcard

[ayylmao]

I want to use again my R4 on my 3DS but i can't get it to work, it used to work, i tried the bluecard fix but i can't install it because it gives me an error i tried the whitelist 0 and nothing just the black screen saying to refer to the user's manual the TW_FIRM just gives me an error

Thanks in advance

Edit: back in the day my r4 used to work
