[Completed] How to Upgrade Andriod from 4.0.4 to 4.4 on Unlocked Samsung Galaxy S3

Hello,
I bought the AT&T Locked Samsung Galaxy S3 having Android version 4.0.4 , After a while I unlocked the phone with AT&T by cancelling the contract and using local service provider and now when I try to update Android version 4.0.4 to 4.4 , its saying current software is up to date.
Can you please explain how to update Android version.
This this thread will show you how. Its a guide for retuning to stock but its the same process as upgrading, provided you pick the latest firmware to download

It seems not that easy according to this thread: Downgrade Verizon Samsung Galaxy S3 SCH-i535 from 4.3 to 4.1.2, is it possible.
And this: [Q] Hwo to downgrade to ML1 from Verizon S3 SCH-i535 JSS15J.VRUCNC1?.
Best to ask in the Verizon Galaxy S III Q&A, Help & Troubleshooting.
Maybe someone with the same device can confirm and/or explain why it's not possible.
(AFAIK, once flashed KK firmware, the bootloader is updated. If the bootloader is locked and only let's you boot into KK, this could be the reason. Just guessing ...)
Thread closed and thank you.
