**You can begin the following process from any 4.4.x Build/ROM or higher but you must already have Root Access**

**Required** FlashFire - Play BETA - PREVIEW.

**Caution!** The following process is only for the AT&T I337 S4 Variant. Use on any other device may result in a hardbrick!


Downloads:
- I337_OK2_Stock_Rooted_ROM.zip
- I337_OK2_Stock_Rooted_Deodexed_ROM.zip

Attention! Set your screen timeout to 10mins before beginning!

1. Place the ROM onto your device (use either internal or ext-sdcard).
2. Open the FlashFire app and "Agree" to the Terms and Conditions.
3. Press "(+)" twice to bring up the "Actions" menu.
4. Select "Flash Zip or OTA" and locate and select the ROM. Leave "Auto-mount" unchecked under the "Options" menu and press the checkmark to continue.
5. From the main menu Uncheck all options under "EverRoot" and set Reboot setting to "Download."
6. Press the lightning bolt then "Ok" to begin the flash.
7. Once the flash is complete and the device reboots into "Download" mode, flash the I337_OK2_Bootloader.tar.md5 using Odin's PDA/AP slot. Done!

The screen will turn black then display the contents of your system before beginning the flash. FlashFire will pause for about 1 minute while flashing the "system" partition. Once complete your device will reboot and pause on the AT&T splash screen for about 1 - 2 minutes (15 - 20 mins for DeOdexed version) before completely rebooting. Done!

Tip: for blazing fast speed turn off animations from Developer Options and reboot!

Known Issues:
- None!

Optional:
- I337_OK2_TetherAddOn.zip
- I337_OC3_Batch_Debloater (Customizable)

Notes:
1. The above process will not affect your Knox Warranty Flag.
2. The process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery.
3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset.
4. If you are not already rooted (or to unbrick) you must first flash the I337UCUFNB1_Rootable_Full_Odin.tar (use Odin's PDA slot (AP in Odin v3.09+), root with Towelroot, then proceed with the above process.
5. To learn more about FlashFire's capabilities on locked bootloader devices see here: http://forum.xda-developers.com/show...10&postcount=2

Is there a way to root without having to flash back to nj4? I'm already on OC3 and a non-odin method like on nj4 would be pretty nice.

If the folder does not already exist you must first use safestrap to create a nandroid backup and Safestrap will create the folder for you.
2. From Safestrap recovery press "Wipe" then "Advanced Wipe" and wipe everything but your ext-sdcard.
3. From the main menu press "Restore," then select and restore the I337_OC3_Stock_Rooted_Backup.
4. Once complete from the main menu press "Reboot," then reboot into "Download" mode.
5. Last, flash the I337_OC3_Stock_Partitions using Odin's PDA slot (AP in Odin v3.09+) and reboot. Done!

Upon reboot the Safestrap Recovery splash screen will flash a few times before pausing on the AT&T splash screen for about 2 minutes before completely rebooting. **You will no longer be able to access Safestrap Recovery from 5.0 (see notes below for workaround)**

Optional Tethering AddOn:
1. Place the I337_OC3_TetherAddOn onto your ext-sdcard.
2. From Safestrap recovery press "Install," then select and install the I337_OC3_TetherAddOn(Do not wipe prior to flashing!).
3. Reboot. Done!

Notes:
1. The above process will not affect your Knox Warranty Flag.
2. This process will update your Modem, Non-hlos, System, Kernel, Stock Recovery, and Bootloader to OC3 (BusyBox is also pre-installed).
3. Safestrap will no longer function after updating to 5.0. However you can access Safestrap recovery by flashing back the I337_NJ4_Stock_Kernel (reflash the I337_OC3_Stock_Kernel once you are done using Safestrap).
4. The most common cause of an Odin flash failure is a bad usb port or cable. Please check before reporting a failure!
