how to roll back to previous git commit remote code example

Example 1: git remove commits from branch after push

git reset --hard <last_working_commit_id>
So we must not reset to the commit_id that we don't want.

Then sure, we must push to remote branch:

git push --force

Example 2: git reset head to commit remote

git reset --hard <commit-hash> #Please double check your commit hash
 git push -f origin master # this will force update and remove commits after this one
