Black screen brick(low level)
So...I went messing around with those mym, and cms themes. I used the NUS downloader, and thought i did the procedure correctly, put the menufy on the sd, and installed it. I hit exit and only got a black screen. I have no bootmii, no preloader or anything. I did put a patch to autoboot. So when i hold down Y on GC controller i get the 4.0(usa) in the bottom corner. I've tried multiple autoboot discs, all of the universal unbricker, auto boot wad, everything. But i had a theory that since i can still autoboot retail games(and some backups). My question is since NSMB has the 4.1 update on it, if i were to go and rent it would the system update be able to get launched threw the autoboot?? If not i could really use some help.
