So as i was experimenting with the phone i discovered 2 modes the phone can boot in:

1. Hold volume down and power (Phone must be off first): FTM Mode

2. Hold Volume UP and Volume down, Plug in USB Charger (Phone must be off): Download mode???

The second one is a mystery.

Both are a mystery to me. What is FTM mode? Download mode almost sounds like it could be a method to update the os from a ZTE update. That is very similar to how the old LG Optimus M could be reset if bricked.
 
On LG Motion 4G, Download mode is what we use to USB connect to a pc and factory restore the /system. (revert back to stock from a rooted phone)
 
Just to let everybody know what I've found:

Holding Vol down + power goes to FTM mode

Holding Vol up + power goes to Android Recovery

Holding Vol up + Vol down with power goes to a third mode where the screen stays black and the status LED stays on red. According to my computer, this is DFU mode. I have no clue what this is for, but with a little more googling, I'll update on that.
 
Just to update if anyone looks to this as a reference, DFU mode is Device Firmware Update. Its used for when the recovery mode doesn't work.
