you used tempnand to install unlaunch? Well, highly probably your ds is unbrickable now, at least via software. Basically the tools thqat were used before in some guides like tempnand or twlnf, consumed the write cycles of the nand chip and some times (almost ever in the case of twlnf) messed up something in your nand. Probably when you tried to uninstall unlaunch, some changes made with tempnand broke your nand, or it could also be dead because it exceeded the writing cyclesIts okay If I can recover this it would be awesome. I had version 0.8. I uninstalled it using 1.7 uninstall option. My firmware version was 1.4. The only app I can think that I may have used in the past would have been tempnand.
