I need to replace my digitizer on the tablet asus transformer pad tf300t-1e018a. The problem is i did not know there were 4 versions of it before i threw the old one out. Is there a way i can find out from the model number, serial number, or any other specification present on the mainboard or other parts of the tablet except the digitizer ribbon, which version i need to order? Maybe someone with the exact same model can tell me which digitizer they have?
