Hi xda!
I have rooted my J5 (2015 6.0.1 Stock) with SuperSU flashed with recovery (SU binary installed in /su/bin/su) and i want unroot
how i can do a unroot?
There are any problems if I already have installed busybox in /su/xbin/ (/su/xbin/busybox) ?

regards.

The only way you can remove root is by flashing stock firmware using odin, and it is the most easiest, note, you can not hide that you have rooted your phone since knox is e fused, which means once you root, no matter what you do, it will always stay 0x1

@jam66 you should install stock only if you care of stock and your warranty but if you don't mind about TouchWiz you're fine with SuperSu uninstall options.
i really don't want flash stock rom.
i not want install and configure my apps again.
i only want know if there is not problem if i use supersu full unroot if i having installed su binary in /su/bin/su and busybox in /su/xbin/

thanks.

First of all, what is the reason you want to unroot?
Most of the people that want to unroot is because they want to take phone to the service, and they need to have phone status 'official' and you can only achieve that by flashing stock rom..
Edit: YOU DON'T NEED TO RECONFIGURE YOUR APPS, YOU DON'T LOSE DATA WHEN FLASHING SAME ANDROID VERSION USING ODIN

There's a "full unroot" option in supersu settings or you can just reflash the stock boot.img with twrp recovery :)
when you say "reflash the stock boot.img" you mean restore a nandroid backup from a backup made by twrp ??? or a boot.img downloaded from somewhere?

Flash stock rom, this way you will fully unroot your phone and you won't lose any data, after that just install magisk and done, easiest way
mmm i don't know what is the correct firmware version for my phone. i have a J5 2015 Dual-Sim (SM-J500M) but it was imported from another country. i don't know what country and for my country/carrier there are not firmware version. in SamMobile or samsung-firmware

some data:
Android: 6.0.1 (Stock)
baseband version: J500MUBU1BPI1
Compilation Number: MMB29M.J500MUBU1BPI2
Android security revision: 1 september 2016.

YOU DON'T NEED TO RECONFIGURE YOUR APPS, YOU DON'T LOSE DATA WHEN FLASHING SAME ANDROID VERSION USING ODIN
Let me see if i understand to you. that mean i can flash for example this 2Gb .tar.md5 file i will have the same stock rom without root and all my config and data intact?

I personally did this way:
Uninstall root totally from SuperSu app itself.
Let BusyBox as is.
Flash the original boot.img of the rom with TWRP.
And then you can flash Magisk or Phh SuperUser choose what you prefer.
You go to Play Store and install BusyBox Stericson app to manage BusyBox and you're done. It's unnecessary flash the rom , but you can choose if you still prefer.

When you're in TWRP there two options flash zip and flash image.
You choose image, so TWRP "ask" you if it will be for boot or recovery. You will choose boot and then swipe to flash and you're done . That's is all.

@jam66 After you uninstall root completely from device you need boot.img because when installing SuperSu it patches the kernel. So to avoid problems with it, it's preferable to flash the "virgin" boot.img of the rom you're using. This way you will get a clean flash with the Superuser zip of your choice.

mmm it make sense...
now i'm thinking, where i find a appropriate boot.img file for flash in my phone?
looking inside /data folder, i found a compressed backup of stock boot.img created the same day i rooted my phone with supersu using twrp. this file might work for flash with twrp as you suggest?

When I flashed TWRP on my J500m the first thing I did was a fresh backup of my system. So I would pick the boot.img of this backup. After that I proceed rooting my phone. SuperSu makes backup of​ img when getting systemless root. You can try with that img it's supposed to be backup of original personally I never have troubles dealing with it because of the first nandroid backup never need to pick that img.
