[Upgrading, Modifying and Unlocking] dhairyak1:
WARNING: this tutorial is specifically for the Redmi Note 4 [ Qualcomm Snapdragon ] variant. Attempt to try it on other devices may brick your phone.

It is slightly technical but a really easy procedure. So carry on only if you have the skill, patience and confidence. I will not be held responsible for your mistakes, because I have tried this on my device and it works perfectly fine.

***NOTE : All links have been disabled since I am a new user. I'll update them as soon as i am over the restriction. thanks for understanding. (Just google the file you want to download, and they'll easily be available )

This takes barely half hour if you have the proper skill and an unlocked bootloader.

So, let's start.

So there are some steps to be followed over here. You need to complete all of the below steps. Links to the files required will be given below.

1. You need an unlocked bootloader.

2. You need the ADB and Fastboot device drivers installed on your PC

3. The ZIP files required for flashing.

So You will need the Mi Flash tool and MiUnlock tool during the bootloader unlock process. ( The MiFlash tool is available for download. but you can download the MiUnlock tool only if you get the permission to unlock your bootloader from Mi. To apply for a bootloader unlock go here : en.miui.com/unlock )

Once the permission is obtained, download the MiUnlock Tool from the same link, and follow the instructions to unlock bootloader.

The unlocked bootloader is mandatory.

You have to follow all the steps given below once, you have an unlocked bootloader.

Before you perform the below steps, make sure you download the adb and fastboot for your Computer. Download them here : ( *** ) [ONLY FOR DEVICES RUNNING WINDOWS ]

Download the TWRP recovery file for Redmi Note 4 from here : ( *** )

NOTE: You can use either SuperSU or Magisk for rooting your phone. I personally prefer Magisk.

Download the SuperSU ZIP file from here : ( *** )

OR

Download the Magisk ZIP file from here : ( *** )

Once all these files are downloaded,

1> Place the SuperSU file OR Magisk file (whichever you choose) inside your internal storage directory of your mobile device.

2> Place the TWRP recovery file in the folder where the adb drivers (Platform Tools folder) have been downloaded on your computer. Then rename it as "twrp".

3>turn off your device. then switch it on by pressing the volume down button and the power button together.

leave the keys once your device vibrates. This will enable the fastboot mode. (For beginners, It will display a green coloured rabbit on your device with fastboot written ) Connect it to the PC once the fastboot mode is enabled.

4> Come back to your Computer and Open the folder where the adb drivers and the twrp recovery file is copied.

Hold down the Shift key on the keyboard and then right click in the empty space of the folder window.

There will be a menu that pops up with some options. You have to click " Open Command Window Here "

This will open up the terminal/cmd on your computer. (NOTE: Steps given for a PC running the Windows OS only. )

5> In the terminal you have to type a few commands. Again make sure your device is properly connected to the computer and with fastboot mode enabled.

Note: Connect only 1 device running fastboot.

To verify connected devices enter command " fastboot devices " This will show available fastboot devices with a string of letters or numbers.

After verification of connected device,

First enter the command " fastboot flash recovery twrp.img"

Then hit enter.

(twrp can change according to your twrp recovery file name, if you have renamed it as i said above, no wories, carry on)

6> The terminal will indicate completion of the command. once this is done, type in

"fastboot boot twrp.img"

7> You device will restart and the twrp recovery will pop up on your mobile. Now you can disconnect your device from the computer.

8> In the twrp recovery screen click on install, and select the supersu ZIP file OR magisk ZIP file which you had placed in your internal storage. Then swipe to confirm the flash. It will be indicated when the flash is completed.

Once it's done, click clear cache/dalvik and swipe to confirm.

And hit reboot.

Voila! You now have a rooted Redmi Note 4 with TWRP recovery installed.

[

If you install the magisk ZIP or SuperSU ZIP, under some rare circumstances the app might not have installed on the phone. So you might have to download the apk once the phone has started.

Grab the Magisk Manager APK file here ( *** )

Grab the SuperSU APK file here ( *** )

[NOTE :

All the steps are important to be followed exactly. Do not mess up the steps or you might brick your device.

Here unlocking the bootloader is key. Do not ignore my Bootloader unlock thread. Otherwise rooting isn't possible.

This thread is a bit long, sorry for that. But it's written in an easy way so it's better for the new users.

Hope this helps guys. Follow the thread accurately, and it'll work perfectly well on your device.

Cheers.
