Smart IP65 Charger 15A/12V not charging, switching between bulk and abs, after firmware update

I don’t remember when I last updated my charger. Maybe the update didn’t complete correctly in my case. If v3.61 is the latest version from a few days ago, is it possible to upload a previous version of the firmware and then update it again to the latest one?
