While you guys all downgraded successfully, mine is a sad story.

I was trying to downgrade my KO3(bought recently) from 5.14.1 to 5.13.6 using tools from that guide. All things went well but when the update finished and Kindle reboots, it halts and kept this screen.
[Snip of over-large image]
I've tried all methods rebooting etc. After pressing power button for 40seconds it's screen backlight lit up for 1-2 seconds and then turned off. That's the only "response" I got. BTW, the LED is working as normal, turning green as I press the button.

My guess is that the boot is broken. And a notable thing is that my KO3 was shipped with firmware version 5.13.7.1.
So my guess is that downgrading to a version lower than shipped with will break the device.
So CONSIDER THIS when you buy a new device and try to downgrade with this guide.

Misc information:
Kindle Oasis 3
5.14.1 jailbroken using WatchThis method
trying to downgrade to 5.13.6
shipped with 5.13.7.1
