1º sorry for my bad english, I'm from Argentina. I need you help please!!! My A500 is absolutely bricked. Battery charges (red light) and the tablet vibrates (and turns on the light) wen I start it but the screen is alwais black. No acer logo, no android logo, nothing. The reset button isn't help at all. Power + vol[+] + lock screen do nothing. Power + vol[-] do nothing. All the magical buttons combinations do nothing. No rooted device. Help!!
