DSTTi Firmware Help

My brother's DSi's software was updated to V 1.4.5The error message always appears now. I haven't updated the firmware in a while.. Is there a recent firmware update? I checked ndstt.com but their last update was like 3 years ago :(Please and thank you!

It's not realy a good idea to update software for DSi's , As they are hidden block flashcards and could be bricked from been used .Anyway need more about your flashcard it selfIs it's one from http://www.ndstt.net/download.html?

Yeah, I wasn't aware of that when he updated it :( and yes, that's the one.

Updated your firmware. Don't know if it would work though, don't have a ttds card myself.ttmenu_en_Custum.ziphttp://uploadmirrors.com/download/NNEHTDID/ttmenu_en_Custum.zip
