AT&T S4 i337, Is the OC3 (lollipop stock ROM) bootloader or not? - AT&T Samsung Galaxy S 4 General

Hello,
I'm looking forward to flash OC3 stock firmware into my AT&T S4 i337 using Odin. I currently have NB1 (4.4.2) version. Should I expect any issues?
I also want to know that whether it is bootloader locked or not?

Hi,
Do you have a link for the OC3 firmware?
Thanks.

[Q] Help n915a

hi
how can do flash rom stock for n915G to n915A
i have note edge n915A from AT&T i want change firmware from AT&t to any firmware Stock International plz help me
I don't think you can. The international has the Exynos chip set and the AT&T has the Snapdragon.
Plus the boot loader on the at&t version is locked... You'd most likely brick your phone

You'd better find a custom rom for n915A.

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.

Nb1 i337 to Nougat

I was able to get my i337 down to nb1 and rooted using this guide:
https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078
Can I use that as starting point to upgrade to any stable variant of Nougat? Is there guide available?
Thank you so much
