In the following steps we explain how to format the Tengda N9300-B to erase all your information and make it totally clean as it came out of the store.

Before doing a factory reset, we recommend deleting all the accounts on the device, specifically it is useful to unlink the Google account if you are going to sell, donate, or give away your N9300-B.
