Guide wanted for Rooting stock Oreo and flashing custom ROMS

[denzilignatius]

Hey, fellow members. I'm a complete noob. Well, not exactly. I have rooted a few of my older phones and flashed custom ROMs but I have no idea how to root my current phone. I've been trying to find a perfect solution ranging from Youtube videos to our own forum threads but I guess I am not really good at searching. I'd be really grateful if someone could give me a step by step guide to rooting my phone and IDK, maybe unlocking the bootloader (if that's required) and then flashing a new Pie ROM. I'm using XT1084 Stock Oreo 8.1 with the latest security patch. Your help will be much appreciated. Thank you!

Unlock bootloader first

For rooting, installing custom roms. You need to unlock bootloader first via fastboot using ur PC. Search the thread for bootloader unlocking process. And then download and install TWRP. Join telegram group http://t.me/g5splus for custom roms and all stuffs

I do have another question. I'm currently using Pixel Experience 9.0 which is supposedly a TREBLE ROM. I want to switch to Bootleggers 9.0 which isn't TREBLE. Will there be a problem if I flash a Non-TREBLE ROM on a TREBLE Recovery? I'm using TWRP TREBLE. I know I sound a little foolish especially with the rubbish nomenclature but I hope that everyone is able to comprehend my words and possibly even figure out a solution for me.

Nevermind.
Got it.
It doesn't make any difference whether I use TREBLE or Non-TREBLE TRWP for flashing a Non-TREBLE ROM.
