Nice to meet you, *****
Your Fitbit might be vibrating at the wrong time because it needs a restart to be plugged into the charging cable, a reboot, or a software update.
It could be that there is an app that is causing the vibration too.

  1. Press and hold down on the Fitbit’s power button.
  2. Let go of the power button once the screen goes black. This should only take a few seconds.
  3. Wait for a few seconds. Once again, press and hold down on the power button until the Fitbit turns back on.

I have done this the screen is dead nothing happens only when I put charger on does the red X come on


I got you.
Well, this usually happens when you performed a factory reset before unpairing the device. Usually, you should unpair your Versa, forget Bluetooth, and perform the factory reset.
To solve this issue, follow these steps in the order shown: Unpair your Versa.

  1. Unpair your Versa.
  2. Unpair from Bluetooth.
  3. Force quit the Fitbit app.
  4. Turn off the Bluetooth.
  5. Shut off your phone and turn it on after 1-2 minutes.
  6. Turn on the Bluetooth.
  7. Set up your device again. https://help.fitbit.com/articles/en_US/Help_article/1873#replace
  8. If there is no connection, restart your Versa once again.
