[How-To] Root G900AUCU2AOA1 4.4.4 (2/3/2015) topic

**Make certain that your reactivation lock in security settings is off before beginning this process**

1. Take the OA1 OTA update.
2. Download and install Towelroot-v3.apk(this version does not require internet access).
3. Place your phone into "Download Mode" (press and hold the Home, Volume Down, and Power keys until the phone powers on and displays warning screen, then press Volume Up key) and flash the G900A_ND3_Stock_Kernel using Odin's PDA slot(AP in Odin v3.09+).
4. Open the Towelroot app from your app drawer and press "Make it Rain" to root your device.
5. Power off then boot into "Download Mode" again and flash the G900A_OA1_Stock_Kernel also using Odin's PDA slot(AP in Odin v3.09+).
6. Install SuperSU to manage root access. Done!

Notes:
1. After flashing the ND3 kernel your phone will run a little wonky and towelroot may not root on the first try. If that happens reboot and try towelroot once again. Once rooted and after flashing the OA1 kernel your phone will once again run like a champ!
2. Following the above process will not affect your User Data or Knox Warranty Flag.
3. Should the OA1 ota update fail consider returning to stock NCE by flashing the G900A_Downgrade_to_NCE.tar using Odin's PDA slot(AP in Odin v3.09+) then taking the OA1 OTA update. Once updated to OA1 continue from Step 2 above.

[How-To] Update to G900VVRU1BOA8 5.0 & KeepRoot (2/3/2015) topic

**You can Odin back to NK2 at anytime after updating to OA8 5.0**

1. Place the G900V_OA8_100%_Stock_Rooted_ROM onto your ext-sdcard.
2. Use Safestrap's "Backup" function to backup your User Data.
3. Next, press "Home" and perform an "Advanced Wipe" and wipe everything but your ext-sdcard.
4. Flash the ROM using the "Stock Slot."
5. Once complete press "Home" then "Restore" and restore User Data.
6. Last, press "Reboot" and reboot into "Download Mode" and flash the G900V_OA8_Stock_Kernel in Odin's PDA slot(AP in Odin v3.09+). Done!

The phone will pause on the Verizon splash screen for about 2 minutes after following the above process before completing booting.

Notes:
1. The above process will not affect your User Data or Knox Warranty Flag.
2. This Custom ROM process will update your Modem, Non-hlos, System, Kernel, Stock Recovery, and Bootloader to OA8.
3. Safestrap will no longer function after updating to OA8 5.0.
4. When flashing the kernel the most common cause of an Odin flash failure is a bad usb port or cable. Please check before reporting a failure!
