 On PW4, as long as you're on 5.13.3 or older, you can downgrade to older OTA/customer/production versions (black, any firmware; blue, green, pink, 5.11.2).

 I see, so what you're saying is it is safe to use the amazon provided update bins, as I am on 5.11.2
And when you say 'change the number at the end do you mean literally just renaming the file to a different version?
