I updated my Wii to 4.3U using the Wii's system update. I then followed the guide here: http://gbatemp.net/t171901-modify-any-wii-4-3-below It was all very quick and followed the guide as expected. I used SmashStack, installed BootMii, backed up my NAND, and installed Priiloader. Now, about a week later, I can't get the Wii to boot properly. Priiloader no longer runs when I hold Reset as I turn the system on; it just leads to a black screen. BootMii will load if I have the SD card inserted. However, choosing to go to the system menu or to HBC both result in a black screen as well. I tried to restore my NAND through BootMii, and here's what it does: "RestoreMii, NAND ID: ecdc1095 Checking boot2... BootMii found in boot2, ok to proceed. Dump is for a different Wii. Once again, if you are really SURE you want to do this, KONAMI. Otherwise, press [Z] to give up." I am 100% sure that the NAND backup is, in fact, for MY Wii. After that, each time I press any button on the GC controller, it says: "Try harder, Hashimoto-san!" Does anyone know what the problem may be, and what some options would be in this situation? It would be greatly appreciated!
