Root [Virgin Mobile] Just some interiging questions and i need tips

[mudflap2020]

Hey guys as you know my phone has been giving me problems so ive finally had enough and am going to use the warranty to get a new one, now I currently am rooted, with stock rom, and stock kernel and stock revoery. Now to be fully stock I need to get rid of the superuserSU, the question is how, without the abilitie currently to put another custum recovery, I cant think of ways to remove it because its like a system app, any response and help would be appreciated.

Next question is whejn I d0 get my new phone, what should I do? I know I will get the mc1 to mg5 update as soon as I boot it up, so I don't know whaether I accept it or put twrp first, any step by step would be a ton o0f help. and are there any other ways of getting Twrp other than odin and adb, I could've sworn the last time I was expirementing with my phone and stuff a while back like in summer when the mg5 update annoyed all of us I somehow got twrp back from having the stock recovery before, I just don't remember or I mustve been tired or dreaming or something, lol but any other ways of getting twrp would be appreciated.
Yet another question, I don't know which twrp is the best, I believe I had twrp 2.1 or something, but ive heard that newer versions are bad and unreliable and/ or brick, and why is the scrolling and everything from twrp soo choppy? thanks for reading and any helpful anwer is appreciated, happy holidays!

BTW the reason why im returning to best buy is because there is a crack from when I dropped it and my phone just shuts down randomly or tries to reboot and fail, all this when my phone has stock rom, stock kernel, stock recovery, my phone is just rooted with everything stock, no apps even, just stock apps. So im getting a new one and im going to trie to root the new one from scratch, brand new hardware, hopefully no problems

SuperSU has an option in-app to unroot. Have you tried that?

When you get the new one just let it update normally. Check in about phone to see if it already is mg5. Then just root like normal with twrp via Odin.
Odin is the only way to add twrp recovery.

Should work as long as it writes to the correct partition. Technically, you can flash a recovery image straight from a terminal window with the DD command. (ie "dd if=recovery.img of=/Dev/mmcblk0pX" where X is recovery partition number which I don't recall offhand.)
