Hi @Ollymax, it's nice to see you again participating here in the Community Forums, welcome back!

Thanks for bringing this to my attention and the details that were shared in your post. To resolve this situation, I recommend you to check our help article: Why don't I see my heart rate on my Fitbit device? and let me know how it goes. Such information was really helpful for other users that were experiencing the same uncommon behavior.

Looking forward to your reply, let me know if you have any additional questions.

It didn’t work and now all that shows is the logo , and it flickers . It doesn’t connect to my phone and basically I only see the logo now

Your update is appreciated @Ollymax.

Thanks for troubleshooting your device with me. Since the steps from my previous post didn't resolve your issue, please try the below ones to perform a factory reset on your Ionic:

1. On the device, hold all three buttons for about 10 to 12 seconds. 
2. When the Fitbit logo disappears, quickly release the bottom right button, continuing to hold down the left and top right buttons (releasing the bottom right button as soon as the logo disappears is time sensitive). 
3. When the device vibrates, release all buttons. 
4. Wait for approximately 1-2 minutes while the device clears all data. Eventually, the Fitbit logo appears and the device boots and displays Fitbit.com/setup.
5. When the device successfully resets, please use the normal out of the box process of updating the firmware. You can check: How do I update my Fitbit device? for more details. 

Take in consideration that a factory reset deletes any stored data, which includes all data that hasn't synced to your Fitbit account and your applications, alarms, etc. 

I'll be here if you need further assistance. Keep me posted.
