Hello. I don't know what I was thinking when I did this, but I followed a guide from a website called modchipfactory.com to play v7.1 games on my MT-Card. Basically, it was said there that I had to activate MT-Card mode in order to activate the emunand (MT3D-X.X-XXE/U) and go to System Settings and update from there while connected to the internet... When I rebooted the console after that, my REALnand was still in 4.5 and allowed me to go to the MT-Card menu... but when I choose MT-Card mode, the console freezes in a black screen. I tried formatting the 3DS SD Card, reinstall MT-Installer, redownload the launcher, etc., but nothing corrects this issue. I would normally think that my MT-Card is doomed at this point, but strangely enough, I can use my blue card and my NDS games in the micro SD just fine after doing this. I admit that what I did was stupid on my part, but since my REALnand is still in 4.5, is my MT-Card really doomed at this point? Thanks in advance.
