What are you trying to uninstall ?
you want to brick your console?
NEVER uninstall a system file. You are trying to DELETE IOS 57 !!!
STOP.
parrotgeek1 told you to reinstall, not to uninstall.
You are making a mess with your console.
at this point, just stop what you are doing, see if you can still launch HBC, and run syscheck (follow the guide in my signature)
post your result here. (if it still work)
I allowed my self to do all of this because my Wii already has Bootmii on Boot2. Some of the IOSes downloaded from NUS don't properly overwrite the modded versions so I have to delete then install.
(I was using Wiimod 3.2 for IOS reinstallation)
