While the new process for unlocking the bootloader is not fully complete (we are just about done) we've added Build 20 (B20) stock image to the ZTE USA website. This will remove the unlocked bootloader from your device at this time, however you will not be able to update to newer builds just yet if you had originally requested to unlock your bootloader. While we fit the puzzle pieces together, we ask you to give us just a little more time to get everything uploaded and tested so that we can offer you the best experience possible. Thank you for your patience as we get this rolling.

If you are interested in downloading the file which is 2GB is size please visit the following link: and on the bottom left of the page select "Software Updates"

This file is an SD card update and will erase everything on your device internally(SD card will stay intact) and return you to B20. We recommend only users with advanced skills use this file for their development purposes.
