1st Step : Flashing TWRP Recovery Via Odin

What is Recovery? | The Two Android Recovery Agents (CWM & TWRP)

Here, we will use TWRP Recovery. We will install it on the device using the Odin software.

Required: your phone, Windows PC, USB cable, Odin, and TWRP (.tar file)

1) Boot phone to "Odin Mode, a.k.a. Download Mode" by pressing the buttons at the same time: Volume Down, Power, & Home. When the device vibrates, immediately release the Power button while still pressing the other two until the Download Mode's warning screen appears.

2) Press the "Volume Up" button to continue to Odin Mode

3) In your computer, using WinRar or 7-zip, extract the Odin zip file, then run Odin3 v3.09.exe as Administrator

4) Connect your phone to your PC via USB. It should say "Added" on Odin.

5) On Odin, click the "AP" button, find and select the "twrp_2.8_material.tar"

6) Click "Start" to proceed in flashing the TWRP Recovery. *This takes about a minute.

7) It's partially finished when it says RESET! with these three lines in the message box.

RQT_CLOSE !!

RES OK !!

Removed!!

Then, phone will reboot automatically to OS.

8) Sometimes it takes a few more seconds after the phone has rebooted for you to be able to completely close Odin. Just wait for Odin to change its status from RESET! to PASS! and say All threads completed. (succeed 1 / failed 0), as shown in the picture below.

Then, you may click Exit and disconnect cable.

TWRP 2.8.5.0 Recovery is now installed.​

And this is how to boot to "Recovery Mode". Press the buttons at the same time: Volume Up, Power, & Home. When the device vibrates, immediately release the Power button while still pressing the other two until the SAMSUNG boot-screen appears. See photo instructions below.

By the way, see the pictures below for the difference between the Galaxy Win's stock recovery and TWRP's recovery.

Important : NANDroid Backup

At this point, with TWRP Recovery installed, you can now create a NANDroid backup. It's a backup of literally everything in your phone - System, Cache, Data, EFS, and Boot. It is considered to be the top priority of things to do before messing with your phone i.e. flashing ROMs, kernels, or apps. After you create a backup, the backup file would be located in "sdcard0/TWRP/BACKUPS/" for internally saved backup, and "extSdCard/TWRP/BACKUPS/" if it's saved to the external memory. This file can also be transferred to a different storage, say a hard-disk, if you need to have more space on your phone for something else. You may skip to the actual rooting part. But, in case you do want to create a backup just follow the simple steps below.

1) Boot phone to Recovery Mode

2) Select Backup

3) This part lets you name the backup file with whatever name you want, choose whether to save it internally or externally, and pick which stuff you'd like to backup. And when you're ready, swipe to backup.

*This may take 5-10 minutes depending on how big your whole current installation is.

4) Once done, you may proceed with the 2nd part of this rooting guide.​

2nd & Final Step: Flashing SuperSU

SuperSU allows for advanced management of Superuser access rights for all the apps on your device that need root.

Required: your phone, and SuperSU (.zip file)

1) Boot phone to Recovery Mode

2) Select Install

2) Locate the zip file SuperSU

3) Go ahead and swipe to install SuperSU *This takes just 5-10 seconds.

4) Reboot System
​

You now have root access. Good luck!​
