Hiya. I just purchased a GW and an American 3DS with firm 4.5.0 separately. I put all the files for 2.2 Omega in the proper SDs, but when I try to run the blue card to install the GW, I get a black screen saying "An error has occurred. Press and hold the POWER Button to turn the system off. Please refer to the Operations Manual for details" I've tried with a Kingston 32GB microSDHC and Sandisk 256 MB microSD, both formatted to FAT32 with Windows Explorer, and got the same response with both. Anyone has any idea what might be the cause?
