    I fought with a nand over the weekend that done the same thing as you described. It ended up having 4 bad blocks and unfortunately one of them was block 3 which makes it useless since that falls write into the Boot2 sectors..

    Yes. A wii has to go pass all 3 boot stages; Boot0, Boot1 and Boot2 (Boot1 and Boot2 are the only ones on the nand). If any of the boots stages fail then the Wii will crash and render it useless.

    Yes they are interchangeable . I just swapped out my first one this weekend (the one with the bad blocks). The two chips have the same pinout and function the same. As long as it is flashed with the backup from the original Wii it will work just fine.

    Block 2056 is likely a bad block that can't be written to. You can do what Bad_Ad suggested to Zolotor and use the update only option since your programmer is writing properly. Unfortunately you will have to start the write process over again from the beginning unless you know how to cut off blocks 0-2055 from your backup file. Block 2056 starts at the 277770240th decimal (hexadecimal offset 108e7000) so you can make a copy of your backup and cut off the data to that byte. Then set the parameters in Xavbox to start at block 2056 and end at 4096 and choose the update only write option.
