How can i revert a git commit --amend -m without losing my original hashcode and the code i supposed to commit?

Question

I need to revert a wrong git commit --amend -m

1. did git commit without -m
2. did git commit --amend -m "commit message"
3. git commit --amend -m "commit message" changed my previous commit instead of the one i supposed to commit.

is it possible to revert to before the step 1 without losing my original hashcode or the code i supposed to commit?

commit is not pushed yet btw

Answer 1

git reset --soft "HEAD@{1}"
git commit -m "commit message"

HEAD@{1} means "find where HEAD was before the current commit". You can verify it's really the previous (unmodified) commit using git reflog and git show "HEAD@{1}".
