Sense 2 - red cross

[Chue]

This problem comes after 15 months my Sense 2. The last firmware is 210.6, it tried to install 300.X but it back to 210.6.

Hi Chue, my Sense 2 is only 10 months old. I was getting the same screens. Now I can't even turn the watch on. I haven't been able to sync my watch to the fitbit app in a week. This is my  3rd fitbit watch.  I never had this much trouble. I'm thinking of going over to Garmin.

I got my Sense 2 just last month, just before my NY Marathon. (My Blaze's battery is gone. It only lasted 30 minutes while jogging!)  When paired with my iPhone Bluetooth, it automatically started installing a version. When I checked the version, it was 210.6. I assumed that's the latest version. 300.X is a beta version? One of Fitbit moderators of this community site posted the general release of the newest version - 210.6 on Sep. 6, 2024, at 11:52. I assume 210.6 is the latest version officially released. You guys must be experienced and advanced Sense 2 users, so you know something not publicly announced.

Hi there everyone!

Thank you so much for informing us about this situation and for all your efforts.

@Chue and @JoeShio Welcome to the Fitbit Community! @Lucyfan It's great to see you here!

Please try to do the following: 

• Sync your watch with the Fitbit app.
• On the Today tab, tap the device icon > your device > Sync Now.
• If Sync Now doesn't display an update banner, try the following: Open the Fitbit app, tap the device icon > your device > Gallery. The app should display a pop-up to install the missing apps and restore the device.
• If the firmware update banner doesn't appear, please try restarting your watch.

So, Is 300.x the latest official version available as a general release or 210.6 is the latest official version?

My fitbit show only logo and x screen. It can not sync I tried  to disconnect  and reconnect again but not work.

Hi, Thank you for getting back to me.  I'm having trouble pairing my Sense 2 to my phone/fitbit app. I go to set up the watch, I get the screen with the 4 boxes asking for the 4 digits. They don't appear on the watch. It's been over a week now since I was able to use and sync my watch. Just a quick note, I'm able to sync my older watch, Charge 2 with no problems. I really miss my Sense 2! Sent from my Verizon, Samsung Galaxy smartphone
