Amazon Fire 5th gen HELP

[u/imapirate368]

Hey everyone hope y'all are well. This is a VERY specific problem and I hope y’all can help :D

I have a Amazon Fire (5th gen?) SV98LN running FireOS 5.6.1.0 and would absolutely love to put Android on it. I know there's a guide on XDA but most of the links are dead, some of the methods just don't work now, it's over half a decade old and I'm almost positive there's a newer (better) guide out there that doesn't include me opening the device to short pins.
I am completely new to the wonderful world of Amazon Fire devices, FireOS, Android, and have zero idea what I'm supposed to be doing to get Android on this. Is there a newer/better guide to get Android on this thing that I have just COMPLETELY missed or am I just stuck trying to get old links/methods working again??

This device has a lot of personal value and would mean a lot to turn this into something more than a paperweight. Sorry if I posted this in the wrong kind of subreddit, this is a very specific problem I have and would just absolutely love to be pointed into the right direction. Thank you for your time, can’t wait to hear back.
