How to unlock your android without a google account
Switch off your device and remove the sd card, if any.
Press the power button to turn the android off, and then remove the sd card from the device if you have one inserted. This is to avoid it being overwritten during the hard reset process.

Options are:
(a). Wipe all outgoing data from your device. These data are usually deleted by pressing the back or home button, and separating them in safe mode using a small push code.
(b). Put your android device into recovery mode. Different android devices have different methods to boot into recovery mode, but they all employ hardware keys.
(c). Open instagram on your android device. You won't use instagram if you don't have a google account yet.
(d). To get to the sim card, you'll need to replace the sd card in the phone. Press the screen button to turn off the device and then the home screen, and then sign in to your google account.
The answer is:
(b).
