@EvaBunkevica welcome to our Fitbit Community! I'm sorry for the late response. However, I would like to follow up on the issue that you are experiencing with your Versa since it got locked even though you have unpaired with your phone and deleted the app.
Please follow the troubleshooting steps that shared my friend Ricardo in order to unlock your Versa with your phone. If you already tried this, let me know and I'll be happy to assist you.
Keep me posted on the outcome!
