Hi @Mattimoo ! Warm welcome to the forums ! 
I appreciate your message, and I'm sorry to hear your Sense 2 totally died, battery started to drain really quick, and then you saw a red x a couple of times, and when you tried some troubleshooting you just got the logo for a few seconds and then nothing. 

I understand your concern about this situation, and I'll be more than glad to suggest you some steps. 

Please, in the Fitbit app, try to sync your device : 

• With your Fitbit device nearby, open the Fitbit app.
• From the Today tab, press and hold on the screen and pull down until you encounter a progress bar at the top of the screen.
  Release your finger and wait for the progress bar to fill. (You should be able to see an update banner here). 
  
  If the update banner doesn't pop up: 

• Tap the device's icon  > Your device > Gallery. (You should be able to see a message about some installations). 
  
  Finally, try to restart your device, as shown here : How do I restart my Fitbit device?

Hi,
Many thanks for replying
Have tried to restart but just getting :cross_mark:, tried pairing with my phone but obviously can’t see what the four digit code is to pair it as the devise won’t start/ see the screen?
