I recently bought this card, confirmed it was a real R4 card, and have been searching for the correct firmware all afternoon. So far, every one I have found has led to the same error. I took out the microSD card, a 2 GB NON SDHC one, and turned it on, it gave the sd/tf not found error, so I'm sure it's not the SD card. I'm extremely frustrated, and in need of help. This is my first time buying a flash card. Any help would be appreciated. Thank you in advance.
