So why would you want to delete it?FAST6191 said:Actually you could delete IOS16 if it exists, it is the one used for the debug disc from Nintendo and a few select homebrew apps (it is signed by Nintendo but retains the signing bug so is good for downgrading on otherwise locked systems).
To the OP, don't delete any IOSes, at least until the BootMii platform is fully available so you can recover from any mistakes.
