How to make HEAD and origin/master point to same (latest) revision. (HEAD points to latest while origin/master points past revision)

I'm new to git-hub.

I need to update my commit with -m "First" from local repo to git-hub.

Currently git log --oneline shows below stack.

394b23a (HEAD) First 895aa36 (origin/master, master) Second dc7346a Basic Service f627cd1 Data Binding. . . . If I try to git push origin master I get the message: "Everything up-to-date" and remote repo doesn't get updated. I think its because HEAD and origin are pointing to different revisions. I can't find a mean to merge both. I read about git merge but it mostly tells about merging two branches.

Please help to update the same. Thanks in advance.

NOTE: I have used git reset --hard HEAD in near past, which I think may be responsible for this mismatch.

git checkout 394b23a
git branch master -f
git checkout master
git push origin master

the HEAD is not stepping onto any branch, then above commands do:

• checkout the target commit (you're already stepping there, but just in case)
• move master pointer to that commit (no problem, since it is a forward move)
• checkout master branch in order to be stepping onto it (for future commits)
• push (no conflicts, no problems, just forward then OK)
