Method 1: Get a SIM card for another carrier and try it
Method 2: Google "Leaked Z10 OS" and see what you get.
Locate and download the leak for your model (-1, -2, -3, -4)
Make sure that you have a GOOD backup made of your Z10 as the leak install process wipes everything - data, apps, everything out.
Proceed at your own risk.
