Update to my last post.. I tried another SD card and all worked perfectly , so restore seems very card dependant.So to conclued even though you can do a backup with verify and all appears ok , you may not also be able to restore from that same SD card - I hope my finding help the authors , as this is a great bit of software...by teddystacker - BootMii Beta
I have Exactly the same problem.I have Bootmii installed on Boot 2,just did a backup to a fresh sd card , did the verify ok , but what I go to restore , its gives me the same error "Dump is from a different Wii" , so I guess at this stage its impossible for me to restore , unless someone knows different?. I guess I wil just have to wait for Beta 3..by teddystacker - BootMii Beta
