How to undo git flow feature finish?
#These steps should do the trick:
#Get the sha's needed:
git log
#<sha1> is the commit right before the merge
#<sha2> is the last commit on develop before you started working on the feature
git checkout develop
git checkout -b feature/<feature-name>
git reset <sha1> --hard
git checkout develop
git reset <sha2> --hard
#Push your feature branch.
