to uninstall ensou, use the installer. then, reinstall ofw. if you don't reinstall ofw, you'll get a checksum warning when installing ensou again (this is with the official ensou, not sure about anything else). if you install ensou with that warning, it won't hurt it, but it might give you peace of mind to see no warning. I believe the ensou logo is one that will remain after uninstalling ensou, unless you install ofw afterwards. I have uninstalled ensou before. that's how I know of the warning. I don't know if you'll get a warning with other ensou variants.
