I have a black wii 4.3u downgraded using letterbomb. I followed xflak modmii guide and everything is working good. I also installed d2x cios in 247, 248, and 249 according to GAF's tutorial. I have a Seagate ST315005EXA101-RK 1.5TB external that I got from Fry's Electronics. When I first cloned the drive, it transferred all of the files. When I used cfg loader, I got IOS(249)blocked ret=-1. I installed one of my originals through cfg onto the hard drive and it played without any errors. Does anyone else have the same problems as compared to 2.5? Also does anyone know how to get around it? My other Seagate drive works without any errors. Thanks.
