Unroot Zuk edge

hi,
Buying my Zuk Edge at Aliexpress which had a custom rom, i decided to flash it with the official rom (CN/EN version). Then, i relock the bootloader.
Unfortunately, i can't update by OTA because when i want to do it by entering in the "System Updates" settings, there is this message :
"Your system has been root, we are unable to provide the latest version of the system"
How must I do to UNROOT my zuk Edge , knowing my bootloader is now relocked and i'm with the stock official rom Zui 2.5.470 eng/cn ?
Thank you in advance for your help.

Going back to stock! (Completely,including unlocking bootloader)

I need a bit of help here
I'm going back to stock after using only custom roms for more than a year now.
I'm thinking to completely go back to stock (locking bootloader)
i need you guys's suggestions,what should I go with?
ZUI 2.5.104 or 3.1.117 or 3.5.389?
Note : I want only qpst version suggestions,that's why i mentioned these three versions.
Thank you!
Edit : I flashed ZUI 2.5.104 through qpst and found that still my phone shows it has been rooted,couldn't get OTA updates. I want OTA updates too,is there any way?

How can I downgrade from Oreo to Nougat? (Want to unlock boot loader)

So I really want to install a custom rom and I know I need to unlock the boot loader and flash it with twrp. But I been reading around here and it seems unlocking the bootloader on Oreo is not possible and the only way to do that is to downgrade to nougat... except I don’t really know how to do this on my device since as previously stated, the boot loader is not unlocked and I don’t know where the stock rom for nougat is even available to download from, or any necessary tools to download to be able to do this (I’m a complete noob). Some info of my device: A2017u, Oreo, B20
Help would be appreciated, thank you
I think you may need to go back to Marshmallow to unlock bootloader and install TWRP but I'm not on an A2017U so won't try to advise you.
I did revert my own A2017G from latest Oreo back to Nougat ok. Since gone back to Oreo. It seems to work when stock but once you meddle with it that's when all the problems start.
