From Petershih:

We have heard you loud and clear. Throughout the last two months on Z-Community you have voiced the desire for an unlocked bootloader for the Axon 7, and today we are making this a reality.

In fact, an unlocked bootloader was something that has been in discussion internally at ZTE for quite awhile. But upon hearing more and more discussions on Z-Community about this topic, your mod team performed the necessary due diligence to present our case with internal stakeholders. After thoughtful debates and discussions, we are truly delighted to share the exciting news that fellow mobile developers have been waiting for: the U.S. versions of the Axon Pro and the Axon 7 will have their bootloader unlocked upon request here on Z-Community!

There are two important things to note: This procedure is reserved for those with a high level of technical expertise and have had experience flashing custom ROMs. Furthermore, unlocking the bootloader will void the device warranty that comes free with each Axon purchase.

To help streamline requests, we have created Developers Lounge sub-spaces within the Axon [Series] Forum. This is the exclusive space for mobile developers to request unlocking and share tips and tricks. Just to reiterate, unlocking the bootloader will void your device warranty.

To wrap up, we want to reinforce our mission behind Z-Community - share in each other’s passion for mobile and shape the roadmap for future products. While we may not comment on each request, suggestion or recommendation, we indeed listen to what our consumers want and make decisions based on that when possible. Lastly, if you’re a mobile developer and excited about this latest announcement, we want to hear from you in the comments section below - in other words, make some NOISE!
