**You can begin the following process from any previous Build/ROM but you must already have root and Safestrap installed. Make certain Reactivation lock is unchecked!**

Instructions:
1. Extract the G900A_OC4_Stock_Rooted_Backup from the .rar archive and place it into the following folder: ext-sdcard/TWRP/BACKUPS/xxxxxx, fyi...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 G900A_OC4_Stock_Rooted_Backup.
4. Once complete from the main menu press "Reboot," then reboot into "Download" mode.
5. Last, flash the G900A_OC4_Stock_Partitions_wOA1_BL using Odin's PDA slot (AP in Odin v3.09+) and reboot. Done!

After completing the above process your device will pause on the AT&T splash screen for 5 - 10 minutes before completely rebooting.

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

Notes:
1. The above process will not affect your Knox Warranty Flag.
2. This process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery to OC4 and your Bootloader to OA1 (BusyBox is also pre-installed).
3. Safestrap will no longer function after updating to 5.0.
4. The most common cause of an Odin flash failure is a bad usb port or cable. Please check before reporting a failure!
