@krank thank you and sorry
I had the exact same issue and found that I had a bad block in the boot2 sectors. The Wii powered up, the drive light flashed once, the DVD drive spun up but I was left with a black screen.
blackeye... as you are doing your rewrite make sure that you are not receiving any differences in blocks 0 - 7.
and again i get the message:
Blocs write from 0 to 4095
Bloc 2065 different
but still bussy re programming
gotcha. Thats good to know. Thanks.
bad boot blocks wouldnt effect this at all, as the dump would be correct (with bad blocks in the correct place and moved to where they should be).
its only an issue when you are flashing something other than the dump originally on that nand.
yes at last, the wii is finale working again.
