Samsung Galaxy A-510 FD Root Help

[umeryamin]

Hello, I have an A-510FD Duos version. I am bored of TouchWiz UI and want a new UI without installing a launcher. Currently my phone is on 6.0.1 with the latest security patch installed. I want a step by step guide on how to root it with the latest Odin version i.e 3.12.3 as I am a noob when it comes to these things. I have never ever rooted before. Also after a successful root I want help in choosing the right ROM. I would like to upgrade to Android 7.0 and a stock Android UI like in the pixel with Google assistant if possible. Thank you
