If you already managed to root (meaning you obtained bootloader unlock and custom recovery) you could try to s-off with firewater. If firewater doesn't work for your M8 you can try sunshine s-off, as I did.

To obtain root you have to unlock bootloader (e.g. via htcdev.com) and install a custom recover (my personal choice was TWRP). After this you can flash root with your "new" recovery.
After this you have to s-off your device (see my answer above).
If you ar finally s-off you can download a stock HTC backup of the European (WWE) ROM as well as the fitting firmware.
Next step would be to perform a TWRP backup of your device and place the above mentioned ROM backup in your TWRP/Backup/H..../ folder on your HTC One M8 and rebooting back into recovery.
In recovery you can now backup to your dowloaded stock ROM and again reboot to bootloader.
The last two steps are to change the CID to a European (WWE) one (e.g. HTC__102) and after this flashing the firmware in RUU mode.
For a more detailed guide just search on this forums, or simply ask your questions. I'll try to help as good as passible. Remenber I'm not to blame for a brick of your smartphones, should something go wrong during one of the steps.
