Fitbit Alta HR, Flex 2, Alta, and Flex, all these models of Fitbit were released before 2018. The first wrist wearable of the Fitbit was released in 2013, and it is the Fitbit Flex.

Resetting the Fitbit Flex

Fitbit Flex is the first wrist-wearable activity tracker developed by the Fitbit company. The process for restarting is quite different from the latest Fitbit fitness trackers.

You will need the Fitbit Flex charger and a paperclip for the restarting process.

The steps for resetting or factory resetting the Fitbit Flex is as follows:

  1. Pull out the band and take the little machine out.
  2. Put that little machine(the Fitbit Flex) in the charger and give it a power source.
  3. On the back of the charger, you will see a small hole. Gently, insert the paper clip into the hole for 4 seconds.
  4. Remove the pin. Also, remove the Fitbit from the charger.

Since this process removes all the user data, we suggest you perform this reset only when the Fitbit Flex is malfunctioning or when you are giving it to somebody.

Factory Resetting The Fitbit Flex

Factory resetting any device is the process of erasing all the data from it. Factory resetting is essential under these conditions:

  1. When the company suggests you do so.
  2. If you want to give your used device to others.
  3. While restarting or rebooting your device is not solving the device malfunctions.

You will need the help of a Fitbit account to factory reset the Fitbit Flex. Take a look at the following steps:

  1. Go to your Fitbit account and remove the Fitbit Flex from the list of paired devices.
  2. Connect the Fitbit Flex to other Fitbit account.

Automatically, the data of Fitbit is deleted when you remove the Fitbit Flex from from one Fitbit account.
