Ok. I finally got your solution. This should work for sure.
Download the IOS16 version of WAD Manager :
http://www.zshare.ne...575142b4331639/This one tries to detect IOS16 instead of cIOS. So your cIOS won't interfere, and it should load normally.
Then install IOS16, with "IOS16-64-v257-prod.wad".
Which you need to extract from "Wii Backup Disc" using WiiScrubber. Look under the update partion then sys. Then extract the WAD from the disc.
Use IOS16 Wad Manager to install "IOS16-64-v257-prod.wad".
You now should have a working WAD manager.
