I'm running a DSI at 1.4.3u. I just purchased a Acekard 2i, loaded it with the newest firmware 1.8.9 got into the flashcart fine. Turned off the DSI and tried going back in and it gave the black screen error message telling me to turn off the power. Tried reformatting and copying 1.8.9 back onto the sd card and it still didn't work. Swapped SD cards and got it to load, turned it off and now it doesn't load and I can't seem to get it to load no matter what I do. I had a R4I card which I couldn't get to load at all. Reading the forums can this just be a bad DSI, or I'm not sure what steps I should do next. Thanks.
