[HELP] HTC ONE M8 - can't revert back to stock

[jdp2510]

So here's my predicament, a long while ago i had installed a rom to my phone assuming i had done everything correctly. This ROM i installed is the Bad Boys One M8 L Sense 7 v 1.0, it is currently still what I'm currently using. What I've been trying to do for days now to return my phone back to stock. My bootloader is unlocked and s-off. I have been unable to install any ROM whatsoever besides the current bad boyz rom. Also when trying to use sunshine, it seems to also encounter problems. If anyone can offer some help or a method to go about fixing this it would greatly appreciated.

It is currently re-locked, I’ve tried running the RUU after locking it but I still come up with a Error 155. If anyone can offer some help or guidance it would be very much appreciated.

Unlock bootloader.
Install stock recovery
Relock bootloader
Run RUU

Or

Install latest version of custom recovery (in case that ROM uses some crazy method of fetching and downloading "modules") and try to flash new ROM
