Stock Android 4.4.4 KitKat for Samsung Galaxy S3?

[NikoJohn]

I currently own the MetroPCS Samsung Galaxy S3 (Model number: SGH-T999N) running Android 4.3.

I was wondering if there was a way to get stock Android 4.4.4 on my device, like the Nexus 5. If not stock then is it possible to install the official Samsung/MetroPCS 4.4.4 version?

Thanks for the help!

You can install a 4.4.4 custom ROM, but there is no official 4.4.4 for the s3.

I don't recommend you to upgrade since it will lock your bootloader and you cannot downgrade your phone or flash 3rd-party ROM any longer.

Since when does Metro lock the bootloaders?
