I turn my kindle fire 1st gen on and it goes to the (white) kindle (blue) fire screen. There's text at the bottom that says "Booting..." but after an hour, the screen doesn't change. It doesn't say its connected to my PC (windows 10). The power button is green and I have tried a hard reset already. It was rooted but it kept shutting down every time I unlocked the device. So i tried to fix it in TWRP and after a little tinkering around with the settings to try and to fix that problem but then I soon realized ... I @*!%ed up and screwed it up. Any solutions/suggestions?
