Hi I just bought a used umx 693cl from someone and they forgot to take there Google account off so it's still locked up and was already factory reset so I tried asking the person for the info and he won't respond how can I unlock it any suggestions.
It is not recommended to bypass Google lock as it may violate terms of service and can be illegal. It is advised to contact the seller again or try reaching out to the manufacturer or service provider for assistance in unlocking the device.
