Full stock Dev Ed M8 won't take OTA or RUU for MM



I have a Dev edition M8 that i zip RUU'ed back to lollipop. i took a security update successfully, then the 3 preinstall updates in prep for marshmallow. however, I now get an error when taking the actual OTA for marshmallow. I am s-off and bootloader unlocked. I then downloaded the RUU from HTC to run the exe, but i always get error 155. I read @Sneakyghost post about firmware and it said it was either region ID's not matching, or the bootloader being unlocked. I don't see why the unlocked bootloader would be a problem when im s-off and its a dev edition, which is bootloader unlocked out of the box. Anyone know what is causing this?
