[AT&T Samsung Galaxy S 4 General] RockRatt:
UPDATED 4-08-2015 with NEW ATT MODEM OC3 5.0.1 Modem

A NOTE TO CLARIFY MODEMS AND FLASHING THEM: Your Modem is your BASEBAND. Flashing a Modem will UPDATE your BASEBAND.

Flashing a Modem and Updating your BASEBAND does NOT change or lock down your bootloader at all/any further than it already is.

The BOOTLOADER is what determines how locked down your phone is and WHICH root/recovery method can be used.

IF you are on MDB or MDL BOOTLOADERS then flashing these modems will NOT effect your ability to flash anything or change your bootloader.

If you are on MF3 or Newer bootloader then you can use SAFESTRAP to have its recovery and flash compatible Roms AND these modems.

If you are on MK2 bootloader you can use MK2's version of Safestrap and flash compatible Roms and Any of these modems.

To VERIFY "WHICH BOOTLOADER" you have on your phone you can follow these basic instructions.

1. Get "Terminal Emulator" from the play store.

2. Open Terminal Emulator and then type "su" without the quotation marks.

3. Hit the "x" and close Terminal Emulator once you have granted it Root Permission

4. Open Terminal Emulator app, type "su" without the quotes

5. Type getprop ro.bootloader

6. Look at the first line that shows up which is the installed bootloader. It should read "something like"

I337UCUAMDB/ I337UCUAMDL/ I337***MK2/ etc. etc.

I have put the other ATT Modems here as well for users to find the ATT specific modems in one place or in case you need/want to go back to your previous modem. Flashable in CWM/TWRP Recoveries.

FOR SAFESTRAP MF3 and NEWER USERS

This is what a tester DeadlySin9 did. He flashed the MJ6 Modem and it worked fine. He then tested going back to the MF3 modem. So if your signal becomes worse you CAN flash back to MF3 Modem but IF you have problems you may need to follow his advice below.You can see his comments here:

So give DeadlySin9 a Thanks for testing.

FOR MK2 SAFESTRAP USERS

THANKS to Churapa for letting us know these DO work for the newer safestrap as well. Here is his comments and how he did it.

I am putting these ATT I337 16GB and 32GB pit file here as a repository for anyone that may need it in the future. Please use at your OWN RISK and KNOW WHAT your doing and WHEN to use these to save your phones life. PLEASE do your research before using these to flash with Odin. They CAN ruin your device if used wrong or use the wrong one.

I337 ATT 16GB PIT FILE REPOSITORY

Thanks to "mbonus" and "Beast330" for getting us the 16GB pit files.

I am thinking there is no difference between the 16GB and 32GB pit file as they are exactly the same size and have the same exact md5 even though pulled from different phones.
