[Xposed General] Homeboy76:
Two ways to install Xposed on a AT&T Samsung Galaxy S4 (SGH-I337) with DeOdexed ROM

There is a lot of uncertainty about installing Xposed on AT&Ts Samsung Galaxy S4 (SGH-I337) with a DeOdexed TouchWiz Lollipop 5.0.1 ROM. The three questions I had were: 1. Can it be installed? 2. Are there 'installation instructions' to install it using FlashFire? 3. Where can I find DeOdexed, TouchWiz, Lollipop 5.0.1 ROM(s)?

The answer to my questions are: 1. Yes . 2. No. 3. All things AT&T [MK2 NB1 NC1 NI1 NJ4 NJ5 OC3 OC4] and ROM List by guut13, and [How-To] Update to I337_OC4 - 5.0.1 and KeepRoot by muniz_ri.

Actually, there are

two ways to install Xposed on an AT&T Samsung Galaxy S4 (SGH-I337) with a DeOdexed TouchWiz Lollipop 5.0.1 ROM

. One, has 'Installation Instructions': NC1 Flasher

So, for all the AT&T's Samsung Galaxy S4 (SGH-I337) users, I have done the research and written the Xposed 'Installation Instructions' for Flashfire and put all the Xposed 'installation instructions' in one place.

First, I'M NOT RESPONSIBLE FOR BRICKED PHONES OR LOST DATA. YOU ARE RESPONSIBLE FOR ANY POSSIBLE DAMAGE DONE TO YOUR DEVICE AS A RESULT OF CHANGES (FLASHING, ETC.) YOU MADE. I WILL NOT TAKE ANY RESPONSIBILITY FOR BRICKED PHONES, LOST DATA, ETC.

Second, I must give credit to the following individuals for their work and by extension any individual(s) they have given credit too. Their work helped me write the Xposed 'Flashfire' Installation Instructions for AT&Ts Samsung Galaxy (SGH-I337) with a DeOdexed, TouchWiz Lollipop 5.0.1 ROM.

Additionally, I recommend you read their articles for additional insight.
