D800 broken download mode

I once bricked my phone by installing a L01F ROM on my phone by accident, and had to manually reflash every partition in windows CMD prompt. I have been using my phone fine since I recovered from the brick but I was going to tot to stock and update to lollipop but my download mode says secure boot error and shows up as qhsusb_bulk in device manager and gives me a ton of partitions. I have been looking around for a solution but cannot find one. The only thing that is broke is my download mode. I have recovery and a booting ROM.
