Today, I began to hack my 4.0U Wii. I got all the way to installing cIOSx rev19, but hit a big bump in the road. After attempting a network install, I received ERROR (ret = -116). My wii is connected to the internet and the network test did work. I tried to use the wad install be manually downloading IOS57-64-v5661.wad onto both an SD card and USB. But it didn't work. Instead, I got an ERROR (ret = -2). The SD card would only mount if there is no wad on it. otherwise I would still get the same error. Your help would be really appreciated.
