You can either do
git reset --hard ORIG_HEAD
(git will set ORIG_HEAD before things like pulls or resets, so you can
always go back), or, if you have reflogs enabled (and if you set up your
repository with a modern git version it probably will be enabled by
default), you can just do
git reset --hard @{1}
where "@{1}" just means "HEAD ref state one change ago" (the same way you
can say "@{2.hours.ago}" to mean HEAD state two hours ago).
In either case, double-check that that is indeed the version you want to
revert to with
git log ORIG_HEAD
or
git log @{1}
first, since obviously if you give "git reset --hard" the wrong version,
it will reset to the wrong state. Although especially with reflogs, your
previous state will always be logged, so you can always re-do what you
undid by (again) doing "git reset --hard @{1}" to get back the previous
state ;)
ALSO! Make sure that you don't have any dirty state in your working tree
that you don't want to lose! "git reset --hard" will do what it implies:
it will reset your tree. Very much including throwing away all your dirty
state (and that you can't get back by going to a previous commit, since
it was never committed!)
