Can I root or downgrade?

There's a Google Sheet with Firmware versions and downgrading and rooting info.

Discussion about the Google Sheet

Fire OS 5.3.1.0 was the last rootable version for all Fires,

except the HD 10.

Do not attempt to downgrade. - 7th Oct 2018

Fire OS 5.3.1.0 can be rooted but not rolled back.

5.1.4, 5.1.3 and 5.1.2.1 cannot be rooted (31 May 2016)

but both can be downgraded to 5.1.2 (see restore firmware with stock recovery)

5.1.2 can be rooted by Kingroot

or manually install supersu with a terminal emulator

Word of caution: do NOT reboot after running SuperSume; device will soft brick. Immediately start FlashFire and proceed with rom install. This condition does not apply when using Root Junky's approach/tool to replace KingUser with SuperSU. Also note SuperSU is a prerequisite for using FlashFire on FireOS.

Note: If the Kingroot 4.x app repeatedly fails around the 30% mark, try Restoring firmware in Stock recovery.
