  • SD card corrupt. It isn’t. No phone calls. Shows smn900 not smn900T (No SIM)
    I wouldn’t use this.

    • Hi, restore backup of the previous ROM, or download stock firmware for SMN900T from and flash it via Odin.

  • Are you sure this works on the AT&T variant (N900A)? Everywhere else I’m reading there’s no way to install AOSP-based ROMS on it due to a tightly locked bootloader.

    • Not tested, as we doesn’t have all the variants of each phone, go and check on CyanogenMod official page.
      Also, your mentioned site didn’t posted any cm13, they have only cm11 and 12.1 for note 3. Thanks

    • Also check Source link at the end of this post. This is an unofficial cm ROM, but stable a lot, also for any note 3 with qualcomm snapdragon processor including note 3 at&t.

  • it cant be installed on at&t variant because it has a locked bootloader…………any attempts to flash it on an at&t note 3 will end u in a boot loop… not try to flash it on a sm-n900a
