RiderLeangle said:OK, It started doing something else weird (and was working fine minutes before that).
It suddenly stopped again, I turn it on and the bottom screen is just white and the top screen is black and in smallish yellow at the top left it says "0000FE00"
A quick google search reveals that you are not the only one with this problem.
There is another guy here: http://techforums.nintendo.com/nins/board/...;thread.id=1170 with the same problem. Turns out that all he could do is send it in for repair
There is one thing you can try however: ''I had a problem with my Japanese DSi, where it would lock up in a screen that appeared to be the first of the starting sequence. It was completely non-responsive.
After a while, I figured out that if you hold all the buttons (short of the d-pad) and turn the system on (holding all the buttons down until the system fully boots) it'll perform a factory reset.''
Good luck!
