can ur micro sd card be read by your comp? if it cant if means something is wrong with the contact part/got scratched. happened to me, people say u can reformat it with a cellphone but i have no idea how that will help

 

Probably a connection problem. Paper trick?

 

Once in awhile mine does the same and I just take out the sd card put it back in the R4 and try again.....not all problems are solved with formating your card.....

 

That may be the problem. Did you scrape the contacts when you put it in the R4? Sounds stupid, but that's what can happen.

And the paper trick, stick a piece of paper between the R4 and DS so that the pins make better contact. But since it gets stuck at the loading screen that won't help, don't know if you can do that with the Micro SD and the R4 itself though.

 

I reput the system countless amount of times....that paper trick did not work. I don't get this.. at all what should my format be and what allocation size?
