PRIMOC or PRIMOU
there are two small over the air update released for OneV. this first one flashes a new radio that has better battery calibration drivers. if you haven't updated the the OTA it might help with battery calibration.
You can not flash OTA zips.
You must have stock recovery.img , stock boot.img and bootloader relocked, (unless S-Off) to complete the OTA, oh and don't forget, stock Rom of course.
