Thanks to everyone that submitted their Fire TV serial number information, I’ve been able to determine a relationship between the Fire TV’s serial number and the original software version likely on the device. Since the serial number is written on the outside of the Fire TV’s box, it is now possible to know if a particular Fire TV is rootable before purchasing it at a retail store.

The chart below may not be 100% accurate. I did received a few serial number submissions that do not conform to this chart, but I believe those submissions were mistakes by the submitters. If you purchase a Fire TV that does not follow this chart, please email me about it. Also, please continue to submit your Fire TV serial number information whenever you purchase a new unit so that I can keep this chart accurate.

(Via towelroot) Notes 4011-4182 51.1.0

or

51.1.0.1 Yes Rootable, but are more likely to refuse to go past a blocked update during initial setup. See this guide for more information. 4183-4194 51.1.0

or

51.1.0.1

or

51.1.0.2 Yes It's unclear if this range falls into the previous group or the next group, but it is rootable. 4195-4302 51.1.0.1

or

51.1.0.2 Yes Best for rooting because blocking the initial update is less likely to result in an error message and these likely don't require downgrading to install ClockworkMod. 4303-4311 51.1.0.1

or

51.1.0.2

51.1.1.0 Yes It's unclear if this range falls into the previous group or the next group, but it is rootable. 4312-4355 51.1.1.0 Yes Rootable, but not ideal because they require downgrading to install ClockworkMod. Some have newer recovery partitions which block downgrading. My downgrading guide covers how to bypass the downgrading block. 4356 51.1.1.0

or

51.1.3.0 Unknown It's unclear if 4356 falls into the previous group or the next group. 4357-4384 51.1.3.0 No 4385-4411 51.1.3.0

or

51.1.4.0 No It's unclear if this range falls into the previous group or the next group, but it is not rootable. 4412+ 51.1.4.0 No

Regardless of which Fire TV you have, you should follow my Starters Guide for your best chance at rooting.
