I had to do a Windows 10 resintall on my Jumper EZPad 4s Z83000 tablet. Now it has no touchscreen, no wifi, no sd card, no battery icon or power management, no bluetooth, etc. The drivers on Jumpers website simply do not work. I now have a tablet that is no longer a tablet. If someone can help me with get the real drivers and explain how to properly install them I would be forever grateful.
