Sense doesn't power on, after firmware update

[alihabib.in]

I use a FB Sense (been 2 years exactly since activation).

*********************************************************

Last seen charge: 93% (before firmware update)

Charger: Works well, tested with friends FB sense

Lights: No sensor lights flashing

*********************************************************

Recently I updated my Fitbit tracker, with a firm update through the app. After the update, I faced a glitch the device became unresponsive and tried to reboot by pressing it for 10 secs.

The FB logo showed up for briefly, before it went all blank again. After that, I have been trying to power it ON, but with no luck the device doesn't power on.

Post this incident, I have charged it for 30 mins & overnight too. Trying to do all kind of reset, the device just doesn't respond. Exhausted with all DIY options now

FITBIT's response

*********************

Since the warranty is over now, i.e 1 year for them. They will not help any further, 

I don't ACCEPT that resolution, because I am 100% sure, the device malfunctioned after installing their firmware update. Fitbit is however, not helping anymore. 

If anyone faced similar issue, please suggest how can I rectify this.

Hi, @alihabib.in  - it is possible while doing a factory reset that it fails and presumably if the watch loses power during a firmware update it can also fail.

In either case the watch may not be recoverable.

You can try to chat via the Fitbit App, click profile photo, Help & support, Contact Customer support, and get them to take you through a factory reset which if it does not work then your watch is unfortunately dead.

HI @Guy_ - Just noticed, the device sometimes vibrates (1/10 times while pressing power button) but shows nothing on screen. I have discussed this with FB already, they offer no help on this.

If you’ve changed your clock face, have you tried changing the face back to original? The update may not support  the clock face?

*** UPDATE ***

Issue still persists !

For a brief period, the watch powered on for few days, and then went to CONTINOUS REBOOT mode !

Hi there, @alihabib.in.

Thanks for confirming the steps that you've tried so far. I'm glad your Sense started working well and I'll mark your post as the Best Answer to help other users who might have similar issues.

Happy stepping!

I thought the issue was fixed, but all of sudden the Fitbit has gone into a INFINITE reboot mode after the logo. This time i thought, I should wait for few days but now its been a week already. 

Tried Hard Reset, Charging entire day and proper debugging with Fitbit Chat. Nothing works ! I assumed the problem was with Clock Face, but it seems the issue is something else. The last time I saw it active was while doing Payment on watch.

Any help, would be much appreciated

Hi there, @alihabib.in.

Thanks for letting me know about your Sense. I'm sorry this happened again, and I appreciate you for troubleshooting your watch. I went ahead to check your details and it seems you already got in touch with our Support team. Because I don't have access to your case, my best advice is to get back to them in order to receive more information about their resolution.
