Important Information & Disclaimers
Purpose of thread:
This thread is opened in order to get feedback from flashing and testing the official CM13 releases (snapshots) & nightlies on the AT&T Galaxy S4 SGH-i337 (jflteatt) and the Candian Galaxy S4 SGH-i337m (jfltecan).
CyanogenMod Info:
CyanogenMod 13 (or CM13 for short) is a free, community built, aftermarket firmware distribution of Android 6.0.x (Marshmellow), which is designed to increase performance and reliability over stock Android for your device.
CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.
The AT&T Galaxy S4 SGH-i337 (jflteatt) and the Candian Galaxy S4 SGH-i337m (jfltecan) had separate CM builds until CM11-Snapshot-M3, after which all Galaxy S4 variants were merged into a unified build (jflte). Due to the pain it was to maintain all those devices in one build, CM de-unified the Galaxy S4 line as of CM12.
All the source code for CyanogenMod is available in the CyanogenMod Github repo. If you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.
Disclaimers/Warranty:
Like any other custom ROM installation, needless to say that this will void your warranty and possibly ruin or brick your device. You've been warned...
Code:
#include <std_disclaimer.h>
/*
* Your warranty is now void.
*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you.

Credits/Thanks:
invisiblek has done most of the work, with contributions from FarmGeek4Life. I am just allowing it to benefit those with AT&T & Canadian S4s by providing support where I can, and putting time into testing and debugging when I need to.
Note: Most of this I shamelessly copied from invisiblek's CM12 post on the Verizon Galaxy S4 forums, he's the expert.
Download Links & Installation
CyanogenMod:
Releases/Snapsots: http://download.cyanogenmod.org/?device=jflteatt&type=snapshot
Nightlies: http://download.cyanogenmod.org/?device=jflteatt&type=nightly
Google Apps:
Make sure to get the latest Google Apps from OpenGApps.
Installation limitations & instructions:
The CM13 builds linked above were built for the AT&T variant SGH-i337 (jflteatt). The Canadian variant SGH-i337m (jfltecan) doesn't have any official CM builds since the de-unification in CM12 (see 'CyanogenMod Info' above), but the AT&T variant SGH-i337 (jflteatt) builds should work on the Canadian variant SGH-i337m (jfltecan) since they're basically the exact same hardware (you'll need to work around the Status 7 error when you try to flash a jflteatt build on your jfltecan device by flashing a matching CWM or TWRP recovery for the jflteatt build that you want to flash, as explained on the CM forums).
You might not be able to use this ROM if you're not on certain bootloaders. I would recommend you be on either the UCUAMDB or UCUAMDL bootloader (run this in a terminal to find out: getprop ro.bootloader ).
The CyanogenMod team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!

Thanks! I'm currently running cm13 as jfltexx (Intl) on my Canadian i337m. Is there any advantage to switching to the jflteatt version?
when I try to flash the att version on TWRP it says it's not a jfltecan version and therefore cannot continue.
I have a rooted i337m on CM 12 with bootloader I337MVLUFNE1
My understanding is that to use CM 13 I will need to do the following:
1. Install the UCUAMDB or UCUAMDL bootloader
2. Flash the version of recovery that corresponds to the cm13 version I wish to use
3. Backup, wipe, flash CM13 ROM and GApps
I have no idea how to do steps 1 and 2. I've never messed with the bootloader and can't seem to get twrp manager to flash a .img file.
Help please!

Where did learn these? Does this apply to a phone running CM 11?

After making that post, I did eventually get CM13 on my i337m.
As far as I can tell, all you need is an unlocked bootloader that will allow you to flash roms. If your phone is rooted and you can flash roms, then whatever bootloader you have is good enough.
You do need to have a version of recovery that corresponds to the CM13 rom that you want to flash. If you have an i337m, chances are you have a jfltecan recovery - there is no jfltecan CM13, so you need to change recoveries. If you want to flash the jfltexx CM13, you need jfltexx recovery. If you want jflteatt CM13, you need the jflteatt recovery.
You should be able to change your recovery by changing your phone model in TWRP Manager and using it to reinstall recovery - for some reason this kept failing for me so I stopped trying TWRP Manager and installed an app call Rashr. I set my phone model in Rashr to jfltexx, which allowed me to install the jfltexx recovery. After doing this, I was able to flash the jfltexx CM13 from recovery.
Which One should I flash Nightlies or Snapsot?? plz help asap
hey i cant seem to install cm13. I re-flashed twrp att version and it still says the error is there? how should i fix this?
How does this work with the at&t variant of the galaxy s4? Isn't the bootloader locked so you shouldn't be able to have TWRP?
Hello, I bought an AT&T s4 i337 and I want to install this ROM someone explains step by step that I must install first, I am something new. Has its original firmware (4.4.2 KK)

You need to be on the MDL or MDB bootloader for it to work. Once you've upgraded past 4.2.2 jelly bean, you're stuck using safe strap recovery.

Yep the bootloader is locked and cannot use TWRP. However, if you're on the MDL or MDB bootloader then you can use Loki to bypass the lock and thus can then use TWRP.

You can't. Once you've updated past jelly bean 4.2.2 then you're stuck using safe strap and can only boot touch wiz based ROMs.

new? its missing
I currently have a Oneplus One with Cyanogenmod 12.0, and I am trying to update of rom to Resurrection Remix. Everytime I try to flash it either it being the Marshmallow or Nougat version they all have the error 7, what's odd is the fact that I am using the bacon version of the Rom is there any fix? or what other Rom do you guys suggest that can possibly work?
Thanks in advance
I Found the Solution!!!! I just updated my custom recovery and it worked
What is the latest build for this? I need to flash modem and bootloader.
Anyone have a good Oreo ROM running on their 920i? I keep having g no network or SIM detected. I am running the latest resurrection remix nougat no problem.
Hello, would there be a developer to be able to offer us an update of the Resurrection Remix custom rom?
Currently there is only version 8.6.6 while the current version is 8.7.3, that would be really cool of him!
I find it really unfortunate that no developer is interested in making roms customs for our dear xperia 5II anymore
