My problem is the same, I have a Samsung Galaxy ACE GT S5830M, I was blocked by introducing too many pattern attempts and asks me gmail account, that does not work is not enabled or the wi fi or data packet. I tried the active call and not working, with the reset by pressing home and menu, either, tried also pressing start and volume and I get a warning with the robot android and says I can disable my phone, something more or less, ask me continue with the volume button up or cancel or resume the button below, gave further and appears as downloading, but then nothing. I gave him my phone down and then was resumed but with the same problem.
