Software was added to Pi 3B+ using bash script. Can’t find ON OFF Shim in pi/uninstall. I want to uninstall anything that was added or changed by the bash script.
Do you much installed to that Pi? Easiest sure way to do it would be to just reimage your card with Raspbian.
Other than that, have a look for an uninstall.sh file in a folder dealing with the on off shim.
