Sense 2 stuck on Fitbit logo

[SunsetRunner]

Been using Versa 3 for a couple years. Decided to upgrade to Sense 2. Unpacked, charged,  and setup my Sense 2 yesterday. No problems. Today the unit shut off. Holding reset button for 10 seconds till logo appears. Logo blinks for about 10 seconds then a red X appears on screen. It attempts to boot again with same results, then shuts down.

Hi there, @SunsetRunner. Welcome to the Community Forums. Thanks for trying to troubleshoot the issue with your Sense 2 before reaching out. 

Please note the issue you're having comes from performing a factory reset without first unpairing your Fitbit device from your Fitbit account and phone's Bluetooth settings. With that being said, I suggest following the steps below in the order listed:

• Unpair your Sense 2 from your phone's Bluetooth and also make sure it's no longer connect to your Fitbit app. 
• Force quit the Fitbit app.
• Turn off the Bluetooth.
• Shut off your phone and turn it on after 1-2 minutes.
• Turn on the Bluetooth.
• Set up your Sense 2 again.
• If there is no connection, restart your Sense 2.

If you can't get started with your Sense 2, usually a missing requirement is the cause. Carefully review the requirements provided in the help article Why can't I set up my Fitbit device? 

If you continue having difficulties to update your Fitbit device, see Why can't I update my Fitbit device?

Hope that helps.

Not having much luck but not giving up on Fitbit! I've been a FB user for some years starting with Charge 3, then Charge 4, then Versa 3 which I still have. Unpacked and successfully setup Sense 2 yesterday. Today is when the display refused to come on.

Here's what I've done so far:

Validated charger and cable using my Versa 3.

FB app on phone: removed Versa 3 and Sense 2 devices

Completly unistalled FB app.

Unpaired Vesra 3 and Senase 2 on phone bluetooth, then shut phone off for an hour.

Reinstalled FB app on phone

Power up Sense 2. Logo appears but never gets further

App "sees" Sense 2 and prompts to setup device

App asks for Pairing Code displayed on Sense 2 but the display is black. 

I'm not sure where to go from here??

@SunsetRunner   It certainly sounds like you have a defective device.  Contact Support for more help.

I just established a new FB account using wife's email. Also attempted setup using wife's Android tablet. 

Same results so the issue appears to be something with my Sense 2.

So disapppointed.

I have been having a similar problem, although I had been using the device for a couple of months before it started.  I was having a lot of syncing problems, so I was getting in the habit of going right to the force stop fitbit, turn Bluetooth off and back on, and rebooting the device.  I also tried rebooting my phone some of those times.  The problem kept getting worse, with the reboot getting stuck on the Fitbit icon.  It would take several attempts to get a reboot.  Finally, it stopped rebooting entirely.  Twice now, I have tried to reboot, and it has done the blinking, the big red X, followed by a permanent freeze on the Fitbit logo.  It stays there until the battery runs out, then I am able to recharge it again and it will work for a while.  It cannot be rebooted, or this will happen again.  I have tried engaging customer support, without much luck.  At this point, I am pretty sure it is a defective device.  Nobody wants to admit that.  Oh, and I have never done a factory reset, so that is definitely not the problem!
