I recently purchased the R43DS upgrade Gold Pro Revolution and a 3DS XL It worked straight away. After a few days of playing around with stuff I decided to change to a different Micro SD card. So I reformatted the old one to use for a different device (my phone) I then installed the latest firmware which was identical/copy paste of the original SD card. It didn't work. So I redownloaded the firmware/kernal and tried again. My 3DS XL and old phat DS no longer read the cart at all!! Help? I do not know what I've done wrong. ______________ 4gb microsd firmware version; wood r4i gold pro v1.51 Note; i tried using the original micro sd card which isn't making a difference? has my cart bricked or is must it be damaged already?!
