Updating TWRP using image file

Hello guys I'm trying to upgrade my TWRP as it's currently on v2.6.3.3. I have accidentally wiped the OS on my HTC M7 Unlocked UK model. I have been using ADB to push the files to the SD Card. I've already pushed the image file into the phone but I'm not sure how to install it like the zip files.

I've already tried installing ROM but I've had no luck stays stuck on HTC logo, I've even tried Nandroid 6.01 but the home screen wouldn't respond to touch.

My HTC has S-ON as I was unable to turn it off.

What are my options?
Thanks
