Download and install SDK Manager. Later, install SDK tools, SDK Platform Tools, Android support library and Google USB driver. Then try again.

Dude that's a m7 recovery
Sent from my HTC One (M8) using XDA Labs
Always check your command syntax is exactly right, when performing fastboot and adb commands.
And yeah, the proper TWRP for your phone would help.

Stuck in the Fastboot/ Recovery

I was trying to root and install a custom rom. When I installed the rom and reboot the device it said no OS installed. I have been trying to send the taimen-opm1.171019.018-factory-e96a86ae.zip file over I realized I have never done that and don't know if there is a fastboot command for push. Any help will be very nice. thanks

You don't send it to the phone but instead you unzip it in a folder with your adb/fastboot files and flash it.

flash the zip? Would I just use fastboot flash image-taimen-opm1.171019.018.zip ?

I found out boot loader was re-locked and I need to unlock it again.
I have my IMEI and Serial, but I need my Product ID to get the code.
How can I get my Product ID?
If someone can get the Product ID it would be appreciated.
