I have a kindle fire 6.3.2, and a few years ago my friend rooted it for me. A few days ago it started misbehaving, pulling the notifications down on every touch. So i decided to restore it (with little knowledge), and did a factory settings reset. The problem is that even after the reset the notifications still pull down all the time and the keyboard miss-types often. To get to the point, i tried the kindle fire utility, and whatever i try to do it starts normally but stops and says: <waiting for device>. I tried updating the drivers but an error comes up and the installation fails. I tried getting the stock ROM from amazon.com like another thread suggested, renamed it to update.zip, and according to the instructions i had to reboot. I rebooted and it boots up regularly. I tried many threads on xda, a few youtube videos, tried everything i did 3 times, and made sure the file is a zip file. Can someone please help me.
