A Code 31 error's caused by ZTE MF192 Modem

A Code 31 error's caused by any number of reasons that prevents Windows from loading the driver for the particular hardware device.

Restart your computer if you haven't done so already.
Hope you installed Zte MF192 Modem drivers/ dashboard before you ran the ZteUnlocker Tool{began your trials} , if you did{Or you've been using it of course} Then re-install the drivers-Uninstall the Orange Modem Drivers/Dashboard from the control panel of course then plug in the Modem for a fresh install-Am saying this probably because there's a likelihood of the drivers getting corrupt.
My last suggestions is that-You can update your entire Windows Operating Systems: if you have access to a fast Internet connection, if not, Use another computer/laptop with Windows Operating System in your trials-maybe a friend's.
The problem's with your Operating Systems and not the Unlocker Tool although an antivirus may be also a factor-like I have stated on this post: some antivirus considers the ZteUnlocker Tool as a virus so it may limit the tool's activity.

-The Zte Unlocker Tool has a 100% unlocking rate-I've unlocked like -9- Zte Mf192 Modems-experienced no problems
