1st : I Try All Method To Root This Device But No Luck
2nd : I Reported Successfully This Method (Thanks To xda Developers)
**Make certain that your reactivation lock in security settings is off before beginning this process**
1. Take the NG3 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_NG3_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 may 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 NG3 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 NG3 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 NG3 OTA update (or place the
G900A_NCEtoNG3_OTA.zip onto your ext-sdcard and sideload from stock recovery). Once updated to NG3 continue from Step 2 above.
Alternative Method for Safestrap Users:
1. Place the
G900A_NG3_100%_Stock_Rooted_ROM.zip onto your ext-sdcard.
2. Use Safestrap's Backup Function to back-up User Data.
3. From the Safestrap recovery perform an "Advanced Wipe" and wipe everything but your ext-sdcard.
4. Flash the G900A_NG3_100%_Stock_Rooted_ROM.zip using Safestrap's "Stock Slot."
5. Then press "Home" then "Restore" and restore User Data.
6. Once complete press "Home" then "Reboot" and reboot into "Download" mode.
7. Last, flash the
G900A_NG3_Stock_Kernel.tar.md5 using Odin's PDA slot(AP in Odin v3.09+).
Notes:
1. The G900A_NG3_100%_Stock_Rooted_ROM.zip process will update your
Modem, Non-hlos, System, Kernel, and Stock Recovery to NG3 but does not
include the NG3 Bootloader.
