Unfortunately most of the older models do not have a way to root them (AFAICT, I've checked in on this occasionally for years). I have a 2017 fire that I was able to get lineage on, but unfortunately it was a mostly broken "test" device. Another 2017 is slightly different and I fried trying to short to ground during the rooting process. I also have 2 slightly newer models that have no root available at all, and are virtually unusable as the stock OS has become so slow (5+ second lag times per tap).
