to uncommit all the stuff: both the message and added files:
git reset HEAD~

in this case you would have to add files and add message before making commit.(changed and added files(staged) are unstaged).

if just just want to edit message of the commit then use soft HEAD:
git reset --soft HEAD~

to reset to a particlar commit :
git reset --hard 4a155e5

Say the branch in which you were working was : master

git add -A
git commit -m "added few changes"
commit hash = 5e108f2

you added your work and then committed it. But then realised you forgot to pull.Now:
git checkout -b newtry master
// git checkout newtry -->optional : try without this
