[Q] How do I unroot the Arc S

So I rooted the phone a few weeks ago using the zergRush method. However, my phone has developed a physical fault and want to send it off for warranty repair (the screen on the lower left side feels loose and creaks when I press on it.)
So obviously I would not be able to send it off in a rooted state, so how do I unroot it and erase all traces of a root from the phone?

You can use flashtool to unroot I believe (though I've not done that myself)..
or.. you can simply repair the f/w using SEUS. that will remove the root..

What's SEUS? Is that PC Companion? Will that fully unroot the phone.

You could flash with Flashtool, don't matter if your BL is locked or unlocked.
Or you could use repair function in PCC/SEUS and the root is also gone.
Or if you have rooted your FW with DooMLoRD's zergRush exploit, look in the thread, for the unroot script.

Hmm, which is the easiest/safest?

SEUS is the Sony Ericsson Update Service - HERE
Use it to repair your phone - will complete remove all traces of root.. and is dead simple to use.. even for a noob!

There was no repair option, however there was an update + restore option, and it does seem like my phone is completely back to its original state. However, how do I confirm that it is actually unrooted?

Try running an app that needs root. You won't get the pop up asking for root permission, and the app won't work fully.

Open Terminal Emulator, type in 'su' and hit <RETURN>. You should get a message that the app has been granted root access. Or not.

Thanks for the answer, but not correct
The real problem was the unlocked bootloader, I had to re-lock it.

@mchaals You're wrong. Flashtool method works for both unlocked and locked bootloaders.

That's right, but it not solves my problem.
I have flashed couple of stock roms and kernels with FlashTool, even with official Sony flashtool, but I can't use SEUS to revert to factory state.
If you want to do that (for warranty issues in my case) you have to upgrade via SEUS or PPC - which is not possible because of the error caused by the unlocked bootloader.
Sorry if I was not clear
BTW I used this method to relock the bootloader:

Custom ROMs for stock kernel

I'm curious on how difficult it is to fix a ROM to run on stock kernel? Does anybody know of a good tutorial? I love my ion but unfortunately can't unlock the bootloader which leaves me with a stock kernel

It's because you have a carrier locked Xperia S. The above method wont work with it, also if you have the SIM unlock code the bootloader wont unlock. Do one thing,mail your carrier and sony asking if unlocking bootloader is possible.
BTW you can still root your device and install custom ROMs just search the forum.

Your bootloader in still unlocked. Here is the status:-
Bootloader Unlocked - Yes ( this means that the bootloader is UNLOCKED)
Bootloader unlock allowed - Yes (this means the bootloader is LOCKED)
So here is what to do:-
1. Flash stock Acro S ICS FTF.
2. Don't power on the device, just close flashtool again and reopen flashtool and flash the bootloader relocking thing.
3. Still don't power on the device and flash the stock ICS FTF again.
4. Power on and check if it says "Bootloader unlock allowed:- Yes" in the service menu.

Don't worry about that download music info not working. It never works at all. Didn't work for me even on my phone's first day. No idea about Bravia Engine though.

Do a backup just to be sure nothing goes wrong, but you should be on the safe side, relock it if you want, you will not lose sms,data,music...etc.

Good luck. Anytime.

as far as i know, relocking the bootloader wipes everything..but i could be wrong..so be sure to make backups of the important stuff like contacts and wifi APs and photos
