Yes, that was my case and this payed method is the ONLY ONE available for Arc S phones that have "bootloader unlock allowed: no" (for the moment ?).

This method is also recommended for those who want to keep there DRM keys even if there bootloader is marked as "unlock allowed : yes".

My story :
I bought an "Omnius Single Android Unlock licence" on gsmserver (because there was a sale and it was the less expensive one I found). You do not need to create an account on Omnius before buying the licence because, the licence you buy gives you the id and the pass to use with Omnius software (it is also possible to change both of them after purchase, I did this).

The instructions given by the Omnius software are very clear but, as noob as I am, I failed to follow them and 4th time was the good one. When you fail, the process simply stop in the middle, so you just have to cancel and try it again.

Your licence is consumed once you succeed (I did not buy 4 licences !), and you see that very quickly on the log that the Omnius Software shows you on screen.

But I don't know if this "Omnius Single Android Unlock licence" does SIM unlock. Previously, before buying that licence and applying Omnius Unlock, I entered the unlock code officially provided by my previous mobile telephone operator.

I confirm that my phone shows : "bootloader unlock allowed: yes"
I confirm that this method preserve the DRM keys so you are able to run Track ID, Wise Pilot, etc...
I installed stock firmwares, as well as other custom roms and kernels with no problem (not AOKP or CM yet because HDMI is unavailable with it).

So... I didn't try and I can't see the benefit to do this as Sony stock firmwares are available on Xda forums => it's not a problem at all.

Hope this helps.

Did you try fastboot 9.7.0 ?
Did you turn "MTP mode" on ?
Did you enable "USB Debugging" ?

Hello Thank for the Thread,
I succeeded unlocking the bootloader of my Xperias arc S (LT18i)!
I only had a problem when connecting the usb cable to the device: the device driver installation didn't succeed and I had to go through the device manager to install it manualy:
* commands below are approximate because translated from french: my system is in French*
1. locate the device in error called QHSUSB_DLOAD (easy, there is a ! sign)
2. right click on it and choose 'update the driver'
3 choose locate the driver on the computer and go to this location (if installation by default):
C:\Program Files (x86)\Omnius for SE\Drivers\USB Flash v2.2.0.5
4. Click next.
One done, it succeeded smoothly.

Hope this can help.

I think the best way to check that is to install Omnius for SE (downloaded from Omnius official site) and plug your phone in your pc. You do not need to purchase anything to do this. I remember that Omnius will detect your phone version and is able to know if it is possible to unlock bootloader or not.
Give it a try.

This guide was very good. I successfully unlocked the bootloader (from allowed: no to allowed: yes) and flash custom kernels.

I have two questions:
1. if I lock the bootloader do I have to pay to unlock it again?
2. can I use SEUS with unlocked bootloader? (I want to use repair section)
