Hi, Friends can any one tell me , is there any way to hard reset a Android based smartwatch like z9 or something just like smartphones hard reset i.e. power button+ volume down button.
In the settings menu - there is an option to factory reset equipment.
This is what is available unless you install custom recovery and wipe and then re-install the rom
Is there any other way to reset .
Not if you do not have TWRP recovery installed - no.
Well - not completely true. You can google reset using ADB interface.
