TTDS HELP!!!!!!!

The only thing that is standing on my SD-Card is a file named 'Pù␀␀␀␀.␀␀␀'
When I turn on my DS it says 'MENU?'

 

That looks like the files on your Micro SD chip are corrupted altogether

 

Do you now what I must do?

 

Good format maybe, Just backup what ever you have left

 

There is nothing left.

I found out that I have a fake card. Is there a way to recover it without another flashcard?

 

Once Corrupted no, Just a good format of the microSD chip maybe with panasonic formatter SD, And redownload new firmware to replace onto it + Games if you did not keep them on your hard drive

 

Okay.
