¶ What operations does a factory reset perform?

Factory reset mainly resets the device's system configurations (such as network settings, user accounts, app parameters, etc.), unbinds remote accounts, and restores the device's system state to its initial factory state.

During the operation, you can choose whether to format the hard drive data: if you choose not to format, an "olduserdata" directory will be automatically created in the M.2 SSD, and the original data files will be saved in this directory.
