Huawei P8 Lite Cannot Communicate with Phone

I have a ALE-L23 and am trying to use Z-Key to sim unlock.
I put the USB Port Settings in Manufacture Mode, installed the drivers, and everything seems to be fine. But when i try to do anything with ZZKey, read phone, sim unlock, or whatever, it throws this error:

ReadFile function failed (Error: 997)
Operation Done.

I even went as far as to unlock the bootloader and root the phone, however nothing changed. Still throwing this error.
Any way around this?
