I have forgotten my old gmail I'd as well as lost my old mobile number which was previously linked with my galaxy on 7. As my little cousin has changed password yesterday by mistake & he can not remember it anymore, therefore I had to go for hard reset. But after hard reset, I am not able to re login using my new gmail I'd. Please help me in the regard. Everytime when I tried to login it show a massage that "your device is Locked for 24 hrs for too many attempts.please try again later." But after 24 hrs it is showing the same massage despite of entering correct user I'd and pass for the new account every time.
