Sense 2 won't sync and it's stuck on error code 3000

[Kasia1021]

My fitbit won't  sync, can't do a hard reset on watch. Watch screen is stuck on date saying a date of 12*31*1999 and says update in fitbit app. I have cleared Bluetooth, force stopped the app, cleared the cache, Uninstalled the app and reinstalled it and still stuck at this screen. HELP!!

Hi there, @Kasia1021. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that your Sense 2 has stopped syncing and now it's stuck on the wrong date and year. I understand your concern, I will do my best to help you with this!

That 12/31/1999 date usually means the watch has lost its internal timekeeping during a failed update or firmware crash and needs a forceful "button" factory reset rather than a simple restart. Since you've already tried clearing app data and Bluetooth, here are the steps to break the "Data not cleared" or "stuck" loop (do this while not plugged into the charger):

• Hold the side button for about 8 seconds until the screen turns black.
• Release the button.
• Immediately press and hold the button again.
• Wait for the Fitbit logo to appear, then disappear.
• Immediately release the button, then immediately press and hold it again.
• You should feel a vibration. This means the factory reset has started.
• The watch will reboot and show the language selection screen.

Once the above has been done, go to Bluetooth settings on your phone, find the Sense 2, and select "Forget Device" or "Unpair." Open the Fitbit App. Go to your Profile picture -> "Set up a Device" and select Sense 2. Choose to Replace the device if prompted. For more information, see How do I set up my Fitbit device?

Thank you SO MUCH! This helped me unlock my phone, was able to restart it and resync it and now it works. I appreciate your help!

Well, it was a short lived victory.  My watch vibrated, fitbit logo turned green with vertical lines, buzzed some more, and now is not syncing with my phone nor turning on or charging or responding whatsoever. I know my watch was fine up until last night with all of this.
