So I have a backup of an old Wii's NAND and Key files saved onto my computer. I recently got a new Wii and wanted to restore my old data. After installing BootMii and the HBC I tried to restore my old data onto the new Wii using BootMii. Something happened and now I cannot access either the HBC or the Wii system menu (black screen/ no signal). I can still access BootMii (installed as a boot2). I neglected to backup the new Wii's NAND files before trying to restore. Is there a way for me to unbrick this Wii?
