for alcatel t10 maybe you can try to press the power and volume up button simultaneously and release the button when you see the android logo and there is a red triangle above it and wait till it reboot this might work..we have the same problem but difference is it stays on the lock screen and it never allow me to unlock it if you're experiencing the same problem this reset instructions might not work.
