    Copy ALL DSiWare to your SD card and copy them back.

    Did you make a NAND backup before using twlnf to modify your NAND?

    Actually I was able to fix it by doing a normal system update (since I was on 1.4)

    It sounds like you can either risk your DSi and update or it will work just fine. It all depends on if you want to take that chance.

    Wait did you updated the dsi and then installed unlaunch? And It bricked? Or it bricked when you update it?

    I installed a version of Unlaunch without write protection on the ticket with TWLnf, since the installer didn't work because of mismatched fat copies. I wanted to update, but we couldn't do that with TWLnf, so I uninstalled Unlaunch (to avoid the data management brick) and copied all my DSiWare to SD, deleted them, and copied them back. However, this still resulted in mismatched fat copies, so I tried updating to undo the 1.4 downgrade I had made in preparation for RocketLauncher. However, midway through it errored, shut down, and would only boot up to black screens. I even tried calling nintendo support about that error, but they didn't know what it meant.

    What about your NAND? What are you doing with it?

    I don't think that calling Nintendo would be a good idea. Just hardmod it.

    For some reason I made ton of nand backups in case of bricking (because im afraid that the console gets bricked because its THE ONLY WORKING ds that I have.) and well, I'm still searching for it. I might aswell use recuva.

    It's a software that you can use to recover deleted files.

    So you tried to update when you had unlaunch installed?

    No, I had uninstalled unlaunch. I couldn't reinstall it either, since I had mismatched fat copies.
