Install the stock kernel and you will unroot. Custom binary count will still be displayed in download mode and you need to use a USB jig to remove it you need to.

Can you explain this procedure please? I have to return a rooted device, too.
But root was necessary for me (firewall, titanium backup) -Thanks

I have a question here. Which one is stock kernel? The Samsung signed one which is included in the stock/default firmware, right? Now it's also been said that to remove the Yellow triangle from boot up it's also needed to flash the stock kernel or a Samsung signed one. So what am I getting wrong here? What's the difference between a Stock kernel and the kernel which is needed to remove the Yellow triangle?
Regards.

Flash full Stock Samsung firmware removes root .
Flash Samsung stock kernel or use recovery jig to remove yellow warning triangle.

Alright. So Post No. 2 makes no sense.
Regards.

Either or both flash a kernel if you still have root flash full firmware .
My method is to simply flash full original branded provider firmware if contemplating a return for any reason.

First of all keep calm.
You will need to use odin to get your phone working back.
See for docky 73's thread in dev section (sticky one). Download your regions firmware and flash with odin. You will get everything there. For how to flash with odin read second post in that thread carefully or read in deadly's guide in general section (it is also sticky)

You can any of those listed for your country/region.
Anything from outside should cause problems like data network not working etc.
You will need to flash csc of your region from odin again to fix that.

I didn't get what you mean.
Your phone is working again?
If yes you can still flash custom kernel/rom and flash back to stock rom via odin anytime.

[help]!!! Help the newbie here!!

Hi everyone, i encounter a problem earlier. Basically i rooted my phone days ago and i m still using stock rom without flashing custom roms. So i eager to try out the mod from Omega thread and install the Omega file from google play. After downloaded the mod (for omega rom) of scrolling wallpaper for TW and i flashed it. Booting up my phone with TW not responding, force close. Try again and again still cant boot into menu. I know i m stupid that didn't do a NAND backup before flashing it, and now i m stuck at this force close thing. So i found out out there there is a stock official rom XXUBMEA, i was previously from XXUAME2, can i flash this rom with odin?What is the complete process i need to do to flash this stock rom? Appreciate that you can help me so i can get back my phone!!

It will not delete the setting apps data etc since u are flashing with odin
However after flashing u make whatever data backup u need and reset the device completely so that the csc will match the new firmware and will work with kies

you can always just flash the stock rom again with odin as long as you can get into download mode but you loose your data.
are you on 4.4.2 kitkat ? because if so, you need a new version of twrp (or use cwm). there is an unoffical version that supports kk and also the original twrp will get an update soon. theres currently a test build, look at the official thread.
dont use it if you are still on 4.3 !
I really really wish people would search and read before messing with their devices... this is the 800th thread on this again.
Take your battery out, and wait for 60seconds, put back in and try to boot into recovery mode, wipe cache and boot up - OR reflash Stock again.
PS: If you have a Hong Kong Note, you need to go off and read... cause you've made a massive mistake playing.

Oh okay then do you know where I can get the original boot loader from. Thanks
I have the firmware ready. Thanks
The original bootloader is installed when you flash a stock ROM via Odin.
BTW, I have never seen a custom bootloader for a Samsung phone.
