I'm helping a friend with her R4, getting some roms and updated firmware for her new card. But it gets stuck at "Loading.." when I try to start it. Could it be that the R4 doesn't support memory cards that're that large? I tried with firmware 1.18 as well as 1.10. Any suggestions? Update: Tried running the R4 with my own 1gb microSD card that I use for my M3 (swapped firmware first), and it ran fine. So I suppose R4/M3 won't work with 4gb memory cards. So my new question would be: Is there a work-around for this? Or do I simply have to get a smaller memory card?
