I just received 3 R4 SDHC cards from R4-Usa.com I've tried several different kernels. Does ANYONE know which ones I'm supposed to use? PLEASE HELP, Yes I am a complete NOOB, I bought these for my children and they are freaking out wanting them to work. Thanks!! P.S I attached photos to see if it may help. P.S.S I'm using a 32GB card, it's supposed to support up to 32GB, so I dont think that's the problem. But I'm going to try a smaller card.
