All buttons did this. I then tried to run the RUU, and lock the bootloader from command prompt. I entered "fastboot oem lock", and it returned the following:

I am unable to relock the bootloader, therefore I am unable to return to stock. I can't boot, and I have no way of recovering. I am sick and tired of these situations with my phone. What on earth could I possibly do to fix this ****?!
Unfortunately, this indicates an eMMC failure on this model. I highlighted the area for you that is the indicator. The eMMC chip is your phone's "hard drive" so to speak. It holds the operating system and all user data. It can fail completely, slowly over time (rebooting to start out) or partially as seen here. In this case your bad block areas are located further down the primary booting structure which is still allowing you to power the phone on but do nothing else. At the moment, we don't offer an eMMC replacement on this model but we do offer advanced data recovery or logic board replacement on it.
Good luck and hope this answers your questions! NO MATTER OF FLASHING IS GOING TO FIX IT. So your efforts moving forward need to be geared towards replacement of the logic, or the phone.
