So as it goes, I loaded sudokuhax to launch hbmenu. I was using TWLnf to install dsiware. TWLnf works great, a game won’t get installed if the ticket and app data don’t match. It’s got good checking before installing dsiware to Nand. If I didn’t get the ticket to match the app data, I’d exit to hbmenu and eject the sdcard, edit the files and insert the sd card, then load TWLnf again and try installing the dsiware. Did that a few times. Well, after this last install failed, I exited TWLnf and returned to hbmenu and ejected the sd card. The Dsi powered off (this has happened before and it powered back on, no problem). I went to turn Dsi back on and now I get the error, “an error has occurred...”. I did notice, while in TWLnf this last time, looked like my Nand had 40mb free. I can boot to the calibration menu, but not to the system menu. I tried removing the sd card and my r4i gold 3ds rts cart. Still, the error persists. I’m now looking at hardmod tutorials. Is there anything else I can do? Thanks for reading.
