So, i tried to install uberion on it and, i didn't put the uberion files correctly. The tablet was stuck at preparing uberion files (or something like that) so i waited 5/10 minutes and..nothing happend i turned it off and removed the sd. Now when i try to turn it on i get a blank black screen.(the green led is turning on too) (now is turning on just by pressing the button..i don't have to hold it) About tablet: WM8650 Android 2.2 Green LED 7 inch What..ca I do to make it work? Please I am so dissapointed of this tablet.
