Approximately how long did the downgrade process run? 10 minutes

When the USB cable was connected, Kindle to PC, could you see the storage on the Kindle? yes
What sort of response did your PC make when you plugged in the Kindle?
It gives me access to the storage, then it disconnects when the "Need repair" screen appears
Did using a USB-2 vs a USB-3 port on the PC make a difference? not checked
Was this same cable and same port working normally before the downgrade? yes
Normally, a Kindle is re-booted without any USB cable connected.
Leave the USB cable connected, Kindle-to-PC, re-boot Kindle (hold power button 40 seconds or more, ignore any pop-up panels seen).
What was the result? Same as above
What OS and OS version in use on your PC:Win 10
USB-2 or USB-3 ports, or both? both
Recovery:
If your PC could 'see' the Kindle storage (even briefly) try putting a file named:
DO_FACTORY_RESTORE
(all caps, no extension, no contents)
into the top level of visible USB storage.
Then use the power button to re-boot the Kindle
describe the result here: it fully recovered to firmware 5.6.1.1
Does the 'hung' Kindle boot far enough to show the main screen, can you access the search bar? no
