Brief steps prior to the issue manifesting: 1. Updated to 4.2U, installed HackMii 0.5 and BootMii beta to boot2 2. Dumped NAND and saved to laptop HDD 3. Ran StartPatch 4.2 and found backups now print blue screen error 002 instead of read errors- ouch! 4. Attempt NAND restore- get 'belongs to different Wii' error 5. Followed guide to correct dump file- insert ASCII 20 byte in Bacby sepecat - BootMii Beta
