Default [Q] Need help on HTC One M8 GPE

So I recently got myself an HTC One M8 Google Play Edition.

I tried to root it and unlocked the bootloader with ADB Commands.

Everything worked fine until I tried to install a custom firmware. It kept me in a bootloop and kept going back into TWRP Recovery.

I found out afterwards that my phone was still S ON.

For some reason, I was able to install Skydragon 3.0.1 custom rom for GPE and I finally got the phone working and usable again.

I thought that it was my chance to try and get S OFF with firewater.

Again, I tried doing so with ADB Command and I got the message that my device is patched by HTC, I am out of luck.

So now I'm stuck on Skydragon 3.0.1 rom. Not to say that it's a bad thing. The rom works GREAT!

But I want to revert back into stock rom and restart anew so I can maybe try and get S off from the beginning because SkyDragon has an OTA.

Apparently it's the OTA that is preventing me completely running firewater.

Is there any way to fix this? Can I still get S OFF from where I am or is there a way to go back to factory settings before all the rooting?

I haven't found any other roms that would install on my phone.

Please help!!!!! =(
