i have been there and followed the steps, i get a message from the dsttflash fixer (cant recall exact name), that says a number and under that ,device not supported, i dont know how to tell the sd is corrupted or not and i have already re-formated it a couple times.
for the record i have formated it to fat32 but it is slooooooooooooooooooooow. any ways around this or do i need a new sd card?
