[Fire General] Morvidus:
I've been stuck on the Fire screen for about an hour. This is where it gets stuck:

Plug in your device with a USB data cable.
Please enable ADB debuging in the developer options (Tap Serial Number in Device Options 20 times if it is hidden)
and unlock your device to the homescreen. This script will root your device.
make sure all adb and fastboot drivers are installed if you have problems.
ACCEPT THE PROMPT ON YOUR DEVICE TO ALLOW USB DEBUGGING!
MAKE SURE "ALWAYS ALLOW" IS CHECKED IF THE PROMPT SHOWS!
Press ENTER when you have followed the above steps.
Press any key to continue . . .
