Root/Recovery/ROM For Polaroid 9 inch Tablet - Android Q&A, Help & Troubleshooting

I got given a Polaroid 902 9 inch tablet for my son.
I want to root it so that I can do some ad-blocking (and other fun stuff).
Does anyone else have it here?
Is there root, custom recovery and roms for it?

I just picked one up at Fred Meyer for $40. Not bad at all for the price, and I'm used to my droid turbo. I was pleasantly surprised by it.
It has a rockchip processor with 4 A7 cores at 1.01GHZ.
I'm not sure what processor model I is though. Cpuz says RK3066 but that model processor was a dual core cortex A9 from over 2 years ago... Only recoveries I've seen fo rockchip processor were for KitKat tablets and earlier

I managed to root it with KingRoot. See the Root Check report below for more info about the device.
