    I have debranded and flashed the AR CV ROM on my Lumia 640 a long time back.
    http://www.lumiafirmware.com/ser/RM-1073/guid/059X227

    The firmware version in this ROM is:
    02177.00000.15184.36002 (probably a bit newer after couple of updates from MicroSoft)

    The firmware version in the new ATT official update is:
    02177.00000.15184.36016

    My question is: Are there any major advantages in the newest firmware version? Do I need to re-brand and flash the official ATT ROM?
    I might be mistaken and the firmware version on my AR CV ROM after the updates might already be at 36016 (I don't have the phone near me right now)

    The differences are likely to be the ATT bits only. Shown as just that last series of digits varying.

    Yes, RumoredNow is correct. The only difference is that the firmware for the ATT model ads a bunch of AT&T Bloatware that gets reinstalled after every hard reset.
