fast boot oem unlock does nothing. No output
I finally got it to work. I tried flashing the recover using the command:

fastboot -i 0x2A96 flash recovery twrp.img


That didn't work. So instead I booted directly into the recovery mode using: 

fastboot -i 0x2A96 boot twrp.img

Once I was in the recovery mode I was able to flash the ROM normally.
