Hi there, @rajniaknt123in. It's nice to see you around 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 is stuck on the Fitbit logo. I understand your concern, I will do my best to help you with this!

Since the steps you tried did not work, I suggest performing a factory reset. Important: Take into consideration that a factory reset deletes any stored data, which includes all data that hasn't synced to your Fitbit account, your applications, alarms, etc. 

With that in mind, please try the steps below in the order listed:

1. Hold the back button for about 8 seconds. 
2. When the Fitbit logo disappears:
   1. Release the button briefly (for less than 2 seconds). 
   2. Hold the button again until you feel a second, longer vibration, which indicates you initiated the factory reset. 

At this point you can set up the watch again. For instructions, see How do I set up my Fitbit device?
