Are you getting this error at the beginning or somewhere in between the installation process? In case of the former try deleting the title.tik file, then use NUSspli to create a new ticket. In case it happens midway you probably need a better power source for the USB drive.
So I open WUP installer on the Wii U. Select the game to install and then select either NAND or USB. Both options give the error right at the beginning before even hitting 1%
How do I delete the title.tik file?
