I have a real ttdsi card and did the 1.4.1 fix a while ago and everything was working till today. Now I get that error has occurred press and hold power to turn system off. I tried to format and redo files but when ran fix again said no upgrade required. So added the firmware update and still gives the error......any suggestions???

I tired this update as well on Dsi xl and it doesn't work either. Still has the power off error.
