You're not giving us a lot to work with here. What were the commands you
made? What was the output? What was the expected output?

Filter-branch is the fallback tool when you know exactly want, and you
don't mind the work of finding the right command to write, plus waiting for
it to run (can take some time in large repositories).
Be aware that even after running filter-branch your repo will still be
pretty big until you rinse out all the old stuff.
Here's an example I ran on some repos a while back:
# remove folders 'sandbox' and 'servers', and prune all empty commits:
git filter-branch -f --index-filter "git rm -r -f --cached --ignore-unmatch
sandbox servers" --prune-empty
# clean away original refs left behind by filter-branch:
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git
# empty reflog:
git reflog expire --expire=now --all
# remove remotes:
git remote rm origin
# remove work tree changes:
git reset --hard
# clean up:
git gc --aggressive --prune=now
Remember to always make backups before you start filter-branching!
