Instructions:
1. Extract the I337_OC3_Stock_Rooted_Backup from the .rar archive and place it into the following folder: ext-sdcard/TWRP/BACKUPS/xxxxxx, i.e. the name of this folder will vary. 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 splashcreen 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 from 5.0 by flashing back the I337_NJ4_Stock_Kernel (reflash the I337_OC3_Stock_Kernel once you are done using Safestrap).
