WM 8650 won't turn on

[rvrr]

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

What..ca I do to make it work?
Please I am so dissapointed of this tablet.

Did you run the changer.bat file to install the files to your sd card? If not you need to do so. If you did, try another number. If it didn't install properly, there is no OS on the tablet so that's why the black screen. What color is your audio port? Does it (or did it) vibrate on startup? Does it have 2 point touch? All this information should help you narrow down your options.
