bought a second hand xperia sp but it had a pin lock code on it when I charged it old owner has forgot code and does not remember google account name or password

I’m not certain but try booting the phone from the Internal low level recovery.

  1. Turn it off
  2. Once off, Hold down a combination of buttons, hold and press Volume Up + Volume Down + Power button until you see a Boot recovery menu. You will notice that your Notification light will turn PINK or RED If that doesn’t work try Holding volume up + power button simultaneously or Volume down + Power button simultaneously. Use Volume up or down to make a selection within the menu, scroll to something that says """"""" Wipe Partition/Factory Reset""""" then Tap the power button to confirm your selection. Do not click anything else but that, you can brick your phone!! Once it boots you have a fresh device :) If you need a Reference, Here is a site that will help: http://www.theandroidsoul.com/boot-sony-… Update me if this helps you, Keep me tabbed :)
