New blaze, already has week of data on it

[timmehkuza]

Bought a Blaze off ebay, nice and used/like new. I picked it up from my mailbox and opened it up, but it was still on. Looked at the features and it said it had been tracking movement and supposed caloric burn while it was being shipped across the country. 

I read a few forum posts that said once you made a new fitbit account and sync your fitbit to it that the data would clear up. However, it only deleted the steps taken, not the calories, mileage, or any other data that it somehow garnered from shipping and possibly its' previous owner. In fact, it seems to have added that leftover data to my account. 

How do I reset the last week worth of data on both the fitbit and my account? I want a fresh start on my stats, not someone/something else's.

Even better, how can I factory reset all data from my account and the tracker so I can get accurate records?

Can I delete data?

 Different types of data can be removed from your Fitbit account. For instructions on deactivating your account, see How do I deactivate my account?
HOW DO I DELETE STEPS AND FLOORS?
It is not possible to delete steps and floors, but you can achieve the same result by negating them:
Log into your fitbit.com dashboard.
At the top of the screen click Log > Activity.
Find the data you want to negate by selecting a date range.
In the activity menu, type in "Driving" and enter the duration and start time.
Click Log Activity. Your steps, floors, and calories burned will decrease for the time period you specified.
HOW DO I DELETE PROFILE DATA FROM MY TRACKER?Fitbit uses your height, weight, and age measurements to properly calculate your stride length (which helps determine your distance), calorie burn, and active minutes.

To delete your profile measurements from your tracker, the tracker must be set up to a different account.  Once a tracker is set up to a different account, it will automatically unlink itself from the dashboard and all of the tracker’s stored data will be permanently deleted from the tracker. See How do I set up my tracker? for instructions on creating a new account. HOW DO I DELETE MY GREETING?If you have a tracker with a greeting that you'd like to delete:
Log into your fitbit.com dashboard.
Click the gear icon in the top right corner of the page. 
Click on your tracker name. The Settings page opens.
Find the Greeting field and delete its text. The greeting will disappear from your tracker the next time you sync.
HOW DO I DELETE MY WEIGHT LOGS?To delete weight logs:
Log into your fitbit.com dashboard.
Click Log and find the Food Plan section.
Click the right arrow until you get to the Plan Summary section.
Click Log weight.
Scroll down to the Measurement History section.
Click the "X" next to the weight that you would like removed.

For a factory reset.....

When should I factory reset my Charge or Charge HR?

To restart or reboot your tracker by turning it off and on without deleting any data, follow the instructions in How do I restart my tracker? Restarting is an effective troubleshoot for many scenarios.

The steps below provide a more complicated troubleshoot known as a "factory reset." Only follow these steps if a Fitbit Customer Support agent asks you to do so. You might be asked to do a factory reset if:

• Your Windows 10 device and the Fitbit app for Windows 10 can't detect your Fitbit Charge™ or Fitbit Charge HR™ with Bluetooth.
• You're using an Android mobile device and having difficulty with notifications or syncing.
• You're using the Fitbit app for Android on a device running an older operating system (4.3 or earlier) and the tracker was previously bonded to another mobile device. 

A factory reset deletes any stored data, which includes all data that hasn't synced to your Fitbit account and your alarms, goals, and notifications. After a factory reset you must set up your tracker again.To factory reset your tracker:

1. Plug your tracker into the charger, and make sure the other end of the charger is plugged into a working USB port.
2. Press and hold the button for approximately two seconds.
3. Continue to hold the button while removing the tracker from the charging cable.
4. Continue to hold the button for an additional seven to nine seconds, then release the button and immediately press it again.
5. Your tracker will advance to a screen that says ALT immediately followed by a white screen. These screens may come up quickly and you might miss seeing one of the screens.
6. Press the button after you see the white screen to advance to a screen that says VIBE. Your tracker will begin to vibrate.
7. Press the button again to advance to the Error screen.
   
8. Press and hold the button until you see the “Erase” screen, then let go of the button.
   

The tracker will now turn off. You can turn it back on by pressing the button again or by plugging the tracker into the charger. You'll know the reset happened if the time on your tracker is 0:00. You can now set up your tracker using the instructions in How do I set up my tracker?

There is no factory reset on the Blaze, and once the past days is synced to the account, there is nothing that can be done on the tracker to affect there data on the website.
