What model of tablet do you have? The when the initial screen is all you see more than likely your tablet/phone is bricked. If this is the case don't worry it can be fixed easily. solution vary from tablet to tablet, to find the proper solution go to Androidcentral.com, go to the forum, find the maker, model of your device then search how to un-brick your device in that section of the forum. Hopefully you will have no problem, I have had SEVRAL tablets and phones all of which I have bricked If I knew the make and model I could possibly help more.
