Hi I bought pendo pad 7 4.2 jelly bean tablet model number is PNDPP47GP does anyone know how to boot into recovery mode? I have tried all possible combinations that i can think of, and still have no luck to get into it. only one time i got into recovery mode somehow(it's black screen and connected with different vid and pid usb values) . after then cannot get in anymore. sigh.. now this cheap table is driving me mad!!
