Hello, I can't access my Fire HD 10 2017 running Fire OS 5.6.0.0 via ADB since I factory resetted it!
When I connect the Fire Tablet to my PC and open a command window and type the command "adb devices" it shows the tablet but it says unautherized!

I am familiar with usb debugging, these are my settings:
unknown sources ON
adb debugging ON
fake location ON

on my pc (Windows 10 Pro 64Bit) I have installed fastboot and adb drivers, the pc recognises the tablet and adb debugging works fine with my phone (onePlus5)

This is what I have tried so far but didn't work:
kill adb-server and restart
restart pc, restart tablet
change usb mode to camera mode
reset adb permissions via developer options
tried another cable, another usb port
uninstalled tablet drivers, reinstalled
reinstalled adb and fastboot
tried to run command window as admin

nothing seems to work...
this is weird because before the factory reset adb debugging worked just fine...
thanks for every advice :D

EDIT:
I SOLVED IT :D
AMAZON PROVIDES INSTRUCTIONS FOR ADB DEBUGGING
https://developer.amazon.com/docs/fire-tablets/ft-set-up-your-kindle-fire-tablet-for-testing.html
after the first steps the dialog "allow usb debugging" showed again :)
