Flash TWRP

Step 1 – Grab your Redmi 3S phone and put it into Fastboot mode. Turn off your phone completely. While your phone is off, press Volume Down  (-) and Power buttons simultaneously until you see MIUI Rabbit or Fastboot logo.

Step 2 – Connect your phone to your computer using its USB cable.

Step 3 – Open up Windows Explorer and go to the folder in which all extracted TWRP Installer files are. Double-click twrp-installer.bat to run it. You will see something like this ;

Step 4 – Now your phone has been in Fastboot mode so you can simply press any key on your keyboard to start flashing TWRP.

Step 5 – Wait till the flashing process completely finished. Once done, your device will automatically reboot into recovery mode which in this case you will see TWRP interface.

Step 6 – The first time you run TWRP, it will ask you permission for system modification. Please keep take this for consideration :

1. “Allowing system modifications” will make TWRP modifying system partition and allows you to gain root access easily – but you won’t be able to flash OTA update.
2. “Keep Read Only” will make TWRP leave system partition unmodified. You will still have OTA update but if you do then TWRP will be replaced.

In this case I will suggest you to do “Swipe to Allow Modifications” so you can proceed with rooting your device.

Step 7 – Once you swiped to allow modifications, go to Advanced Setting >> and choose “Disable dm-verity“. Failed to do so will result to bootloop error / stuck at Mi Logo.

• Via Updater app. Open up Updater app (usually in Tools folder) >> tap on three dots (…) at the top right-hand corner of the screen >> choose Reboot into recovery.

Step 3 – Choose “Install” from TWRP main menu.

Step 4 – Now locate the downloaded SuperSU .zip file and choose / tap that file. Please ignore the SuperSU version in the image below. You can always use latest stable version of SuperSU.

Step 5 – Do “Swipe to confirm flash” and the flashing process shall begin.

Step 6 – Just wait until the flashing process completed.

Step 1 – Finally, choose “Reboot System” to reboot your phone into normal state.
