correct in that you will not be able to downgrade (serious risk of bricking your device).
bootloader is not locked on the S3 AFAIK. (bricked my s3 on mj2 trying to 'unlock' an already unlocked bootloader.).

I agree that the bootloader is unlocked.
I think at times people are calling the newer bootloaders locked because they are unable to downgrade them. Whereas we are calling them unlocked because we can still root them and flash custom/unsigned ROMs.

ATT has been locking the bootloader on other phones such as the Note 3, HTC One XL, and the Moto G so I'm not surprised that owners think their bootloader is locked.

True. I have an ATT S5 and is really annoyed with locked bootloader.

Thanks all for the assurance and support.

I was able to ODIN to stock ROM and SIM unlock the phone.

Background: My ATT S3 i747 was running CM11 Android 4.4.4. Baseband and Bootloader was I747UCDMG2.

Steps:
1. Flashed rooted stock ROM (root66_ATT_I747UCDLK3.7z) using odin from http://forum.xda-developers.com/show....php?t=1739426
Followed the steps in OP.
After flash ODIN showed PASS and phone rebooted. It was stuck in Samsung logo. I booted into recovery. Performed a wipe cache and factory restore.
Phone rebooted successfully after that.
2. Inserted non-ATT SIM and it asked for the unlock code. I had obtained the code from ATT before. Used the code and phone was unlocked.
The same code did not work while I was running CM11.


NOTE: When running stock ROM you can follow steps in below threads if direct unlock did not work for you.

2. http://forum.xda-developers.com/show...5#post38767845 This works only with stock 4.1.1 image (LK3 modem).
See http://forum.xda-developers.com/show...&postcount=323

NOTE: If you need TWRP recovery, see http://forum.xda-developers.com/show....php?t=1739426 and search for "Odin Flashable TWRP Recovery" in OP.
You can download ODIN flashable TWRP from there.
