[Q] TELUS HTC One HELP, how do i get back to stock? topic

So I am a total NOOB when it comes to HTC and might have done something stupid. I just bought a used HTC one and it was bone stock. I decided that I wanted to install a google play edition rom. I did that and the ROM worked great except that I kept losing signal or not getting it at all. I didn't realize that I was supposed to make a BACK up in TWRP. I am trying to get the device back to stock and have tried flashing a zip file via fastboot only for it to fail.

I am not really sure what to do. I didnt realize it was this complicated to get back to stock. I had a GALAXY S3 before and just had to flash stock image via ODIN.

If anyone can HELP, that would be APPRECIATED.
