I have a Samsung galaxy A600FN 2018 running Android 10 with Samsung's One UI 2.0. I want to flash the Evolution X ROM onto it as I'm constantly low on storage and would like to free up some space with a lighter OS and use my SD card as native storage. How would I do this? What is unlocking the bootloader and do iI need to do that? Do i need to root my phone to flash the ROM? I am new to the android rooting community so all help is welcome.
