I downloaded some stupid app that could mess with the GPU, and it said it was going to install files, (yes it needed root) and then I think it said there might be a black screen, and to reflash it again or something, and now my screen boots on, and stays black. If i hold the power button to turn it off, it turns back on itself, shows the Note 10.1 2014 edition logo, and stays black... PLEASE SOMEONE HELP PLEASE PLEASE :crying:
