Go the location where you’ve stored the Android SDK. In the location where you’ve stored the Android SDK, you will find a folder ‘Platform tools’. Open that folder and copy/cut & paste the TWRP recovery in it.
This will make the process of installing the recovery easier, you can also do that without “copying” the recovery in the Platform tools folder, but then you will have to set the environment variables on your system to proceed. so it is recommended that you just transfer the ‘TWRP recovery file’ to the Platform tools folder inside the Android SDK.

Step 5: Unlock the Bootloader on the Phone & Flash TWRP Recovery.
Now on the phone it will ask you whether you want to unlock the bootloader? Click on Yes/Ok which means you want to unlock the lock by OEM. Once done, again get back on the PC.
