ads for what ? where do you get the ads? if your set import n not local set?

Block ads kat mana? In downloaded apps? Or mobile browser?

I think RN3 SD set allow user to give root- like permission to intalled apps.

Last time i read can take a look at Security - Permission - apps.

So the apps that can block those google based ads as well in apps? Adaway and adfree? Might try take a look. Playstore got?
Good to know that. Try do wallpaper setting again to correct its positioning. See how it goes.

Xiaomi can still honor your warranty even if you unlocked the bootloader if you know how to revert it back to locked status.

Hell I even opened my phone already upto dismantling a piece of the motherboard so I can revive it back to download mode.  (there's 2 hardware contact points that is needed to be pressed in order to force the phone into download mode when normal ways doesn't work anymore).

There's a tiny warranty sticker on one of the screws inside it and it can be easily removed and stick it back.
I root so I can install better adblock for apps,  browser,  and youtube.

Yep.
Unofficial way. 

Just double check the rom version you're gping to install. And also drivers setup properly.

When you unlocked  and rooted it,  backup your nvram.
