Shit good question can you get any type of emergency dial pad open and use the dialer code for diag test

No but you can use android commander. Google android commander and download it to your computer. You could actually install a new rom threw it
ok, flashed back to the stock recovery to test some things... basically found out that if you didn't have usb debugging checked last time your phone worked, you have no way to use adb that I know of, which means you can't flash cwm recovery.
So that's the question of the day, did you have usb debugging checked (settings/applicaions/development/usb debugging)
if you did, there may be hope for flashing cwm, otherwise if the zte warp update tool doesn't work you are probably looking at needing to get a new phone. (zte has a one year warranty so this would be a real legit reason to call them up and claim it).
if you did have usb debugging checked, you can try some commands from the command prompt from the ultimate warp drive folder:
shut down the phone and plug it into your computer.
Open command prompt in the ultimate warp drive folder
make sure you see a file called fastboot.exe in that folder
from the command prompt type adb reboot bootloader, don't hit enter yet
power on the phone and as soon as you see the boost mobile animation hit enter
if it says waiting for devices, try typing it again and hit enter, try this a few times while it bootloops
If by some miracle the boot stops and it goes to the green android logo type fastboot devices, you should see something like ? fastboot
if you see that, we can flash the cwm recovery, let me know if you get that far...
if you type fastboot devices and enter and nothing is listed you are screwed as far as trying to install cwm.
Also, if it doesn't go back to the green android logo when you do the reboot bootloader command you didn't have usb debugging selected and we can't do adb/fastboot.

if you get no device found while it's bootlooping you most likely didn't have usb debugging enabled, everything relies on that as far as rooting/cwm are concerned as well as the program, if it's not on, we can not talk to the phone from usb without advanced software and commands that probably only zte would know about...
it's probably not impossible but googling and looking around the forums I don't think we have a tool to solve this.
Your only hope is the zte update tool and ftm mode.
I am assuming you were using the zte update tool to try to get back to stock when you say it only got to 7%, right?
Did you make sure it's not a dead battery causing it to die at that point? You can check the battery with a voltometer, it should be 3.7 volts dc.
Kinda running out of ideas if it's not a dead battery causing it to not make it through the update.
