[AT&T Samsung Galaxy S 4 Original Android Developme] HyeProfile:
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...

#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!
