Soft Brick (I hope) of an HTC One (M7).

Hi all,

I apologise for this as it seems there are a few soft brick posts to do with the M7 here. I've tried following them but I'm not having much success.
Last night I decided to root my phone in an effort to find a good ROM that looked good but also didn't have the same battery drain as the stock HTC Lollipop update.
Everything was ok to start with. Got the unlock code, followed a process on HTConeroot.com. Other than TWRP probably not being the latest version, all seemed ok. After SuperSU wouldn't start due to the incorrect binaries, I tried to update it through twrp and the trouble started. It would not start the OS and, being the noob, I pressed 'wipe' on twrp and i have no arrived at the following:

I am currently in a boot loop. It will not start the OS. I cannot gain access to recovery mode in TWRP either as the screen flashes up team winning and then just restarts. I can gain access to the Hboot screen and from there can do a USB fastboot link. However, I can't do anything with ADB as it doesn't recognise any device as being connected. Fastboot prompt works fine though.

In a nutshell, I'm looking to get the phone working again. I don't really need to go back to a stock rom - I was looking at google play edition or cyanogen (though I'm told the latter isn't *that* stable). Is someone able to help me?
