Steps to install the TWRP on Android devices
Step 1: Download the SDK Platform tool from here
Android SDK Platform-Tools is a component for the Android SDK. It includes tools that interface with the Android platform, such as
systrace. These tools are required for Android app development. They’re also needed if you want to unlock your device bootloader and flash it with a new system image or custom image.
Although some new features in these tools are available only for recent versions of Android, the tools are backward compatible, so you need only one version of the SDK Platform-Tools.
Step 2: Once you downloaded the above file extract it and While holding the shift key+ right click on your mice.
Step 3: Click on open power-Shell windows here or Command prompt here.
Step 4: Download the TWRP image of your choice, which is compatible with your device.
Note: I am not responsible for any kind of hard or soft brick of your device.
Step 5: Then connect your device via USB in fastboot mode.
Note: You can hold the power and volume down key to enter the fastboot mod.
Step 6: Once you connected the device type “fastboot flash recovery twrp-2.8.x.x-xxx.img” without quotation marks.
Here modify twrp.img with the name of your TWRP recovery .img file.
Once TWRP is successfully flashed on your device, type this final command to reboot your device “fastboot reboot” quotation marks.
