TWRP is usually the go-to choice when it comes to backing up mobile devices, installing custom ROMs or flashing ZIP files. In order to replace the stock recovery you will need to know if you have an unlocked bootloader and you will have to check and see if your device is supported. As always, be careful when tinkering with your phone to prevent doing damage.
