First you need to know if your bootloader is unlocked or locked.
Next, while the phone is in bootloader mode, hook it to the PC and do a fastboot getvar all and post what it says for the following...
(bootloader) version-bootloader:
(bootloader) revision-hardware:
(bootloader) unlocked:
(bootloader) sku:
(bootloader) cid:
(bootloader) ro.build.id:
(bootloader) ro.build.fingerprint[0]:
(bootloader) ro.build.fingerprint[1]:
(bootloader) ro.build.version.full[0]:
(bootloader) ro.build.version.full[1]:
(or copy/paste the entire output into a post and I'll pick it out).
If the bootloader is locked, you'll only be able to flash Stock ROMs signed by Moto, and made for the same "(bootloader) cid:" as your phone.
Flashing a ROM will not lock a bootloader that has been unlocked. The only time I've seen flashing a ROM re-sim lock is the Sprint XT1056 where a hack is used to sim unlock it.
Btw, ATT phones usually have the ATT carrier branding on the case, even if it was from Moto Maker.
