[Q] - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

If i have a unlocked s4 can i flash any rom on it

you must have an UNLOCKED BOOTLOADER. so if you have AT&T not at the moment; other carriers too. which carrier did you purchase it through?
There is rooting, SIM/network unlocking, BOOTLOADER unlocking; not the same thing.

You have to wait until a bootloader unlock is released for the AT&T variant. There isn't one just yet.

The bootloader in International i9500 S4 is NOT locked. Only the AT&T S4 is locked.

Factory unlocked question

I just purchased a factory unlocked note 3, about to unpack it but was wondering if I can flash kernels on this phone being as its not a vzw locked bootloader. If so, where do I go to find a forum for that phone?

Is your phone a Developer Edition?
No. Just a factory Sim unlocked phone. It gas no carrier branding. International version

Model number?
SIM unlocked is different than bootloader unlocked.

Your bootloader is locked. No kernels. Safestrap and TouchWiz based ROMs only.
Is there a way to unlock bootloader? Like on sprint, t-mobile phones?

It tells how you can update your firmware. Since you're rooted the ota probably won't work
