I tried to enter a visual security pattern on my shiny new A500. Great, but I couldn't really decide which one to choose, so I changed them a couple of times. Suddenly, the tablet asked for the "existing pattern", although I never assumed to have confirmed any code.
Long story short: Now I need to reset the hardware, because I have NO idea, which code the tablet has stored.
The manual tells me about a factory reset, but (of course) the device asks me for the pattern to confirm it. The reset button on the side is not sufficient to restore factory defaults.
Is there any magic HW trick to reset the device?
Oh, and no, I didn't set up any Google account before this whole mess…
Thanks for any pointer!
