Error Code: 678-1007

Applies to: Wii U

Note: This error relates to the Martini patches, which are now deprecated.

The patcher failed to write out a backup of your Miiverse applet to NAND. This can be caused by an incompatible CFW or corrupted NAND.

Try updating to the latest Tiramisu or latest Aroma build, as these often contain fixes to the CFW.
