How to downgrade LG L90 D410 from Lollipop 5.0.2 to KitKat 4.4.2?
LG Source page has your stock images plus the kernels too. Just scroll down the top section to D410, there are 3 different ones: D410, D410H, &amp; D410HN (pick the proper one for your device).

There are many references to downgrading the D410, but those were inconcise/misleading/incoherent. Only relevant one I found was on XDA for downgrading.

For rooting and tools, I recommend to use this reference.

There were a few variables that would have made this answer too lengthy to post here, so links were used instead.
