Help HTC M8 Stuck in bootloader


May 28, 2017

I have a HTC One M8 which I recently turned on after it being off for a period of time and it is now stuck in a bootloader loop. I was previously unable to access recovery or factory reset mode, I've since unlocked the bootloader using HTCdev and flashed a stock recovery image for my device that I found on the internet and can now access recovery mode, and get a battery bar when the device is off and charging, however it's still stuck in bootload. I have been unable to find a RUU to suit the provider I got the phone from and all of the googling i've done so far leads me to believe that there isn't one. Is there any way to root the device and get S-Off without access to the phone so that I can install a custom ROM? Has anybody else had this issue? I've tried to flash a custom ROM already but get this error message, presumably because the device is S-On:

(bootloader) signature checking...
