[help] Locked bootloader, and stuck in bootloop with TWRP installed.

So I just bought a new phone and was getting ready to reset my Nexus 6 back to stock and relock the bootloader. Using Wugs toolkit I for some inexplicable reason relocked the bootloader before going stock. I got myself stuck in a boot loop but was eventually able to get into TWRP. Since I cannot unlock the bootloader without checking the box in the SW I want to flash a rom there but sdcard cannot mount in twrp and I am stuck. What should I attempt next or should I rma with Moto?
