I have had been fixing some old flashcards i got but i have been stuck on these three right here.
The happybox one gets registerd by my dslite but gives me a black screen whenever i boot the flashcard.
The same applies for the blue one but instead i get a white screen.
The r4gold seems to be bricked entirely, it won't get registerd by the systems at all (no card inserted message, tried it with multiple systems and cleaned the teeth multiple times but it doesn't get registerd).
Anyone able to help me out finding the right kernels? I have tried myself but no results.
