So I chatted with ZTE today and it's not looking good for unlocking the bootloader.  I know we've already kinda known this, but I wanted to find out for myself.  I am not a developer in any way, shape or form, I just enjoy root and all things root.  I could tell this guy was just giving canned responses but, anyway, here is the transcript:
		
		
	
	 Justin H.: “Thank you for contacting ZTE’s Chat customer service, we appreciate your business and value our relationship. At the end of this session you will receive a brief three question satisfaction survey on the support you received. Please take the time to provide your feedback on your experience today. Thank you.” 
 Justin H.: Hello, my name is Justin. How can I help you with the bootloader? 
 Erik S.: Hi Justin, I was hoping you could provide me with some assistance in unlocking the bootloader on my ZMAX Pro today. 
 Justin H.: We do not provide information for unlocking the bootloader on the Zmax pro. 
 Erik S.: Okay. Why is that? 
 Justin H.: It would void the warranty. 
 Erik S.: That's fine, I'm not concerned with the warranty. I am a developer and need access to the bootloader. If the bootloader is unlocked, barring any hardware issues I can fix any software related issues myself. 
 Justin H.: I understand, however we do not have information on how to unlock the bootloader on the device. 
 Erik S.: What about access to adb and fastboot? 
 Justin H.: It would be the same thing we do not have information for those items. 
 Justin H.: You can always search the internet for information on how to unlock the device. 
 Erik S.: Okay, someone at ZTE must have that information. Who would I need to speak with? 
 Justin H.: We do not have that information. 
 Erik S.: Someone does. You can't develop and mass produce Android devices without someone in your company knowing about the bootloader. 
 Justin H.: The best you can do is to go onto our Z community and see if anyone would be able to to give you that information. 
 Justin H.: Here is our z community page: 
https://community.zteusa.com/welcome 
 Erik S.: Lol. C'mon now, Justin. You know that effort is futile. Is there a way I can chat with or call your development team? 
 Justin H.: I understand that you are wanting to have us unlock your device. 
 Erik S.: Yes, sir. 
 Justin H.: We do not unlock the Zmax pro. 
 Justin H.: The only device currently that we are working on unlocking the bootloader for is the Axon 7. 
 Erik S.: You've mentioned that before. How can I get in touch with your development team? 
 Justin H.: You can post on the z community forum. 
 Erik S.: I'm sure the development team isn't very active there. There has to be a way to get in touch with your development team directly. 
 Justin H.: The development team is not readily available to talk to customers. 
 Erik S.: I understand if they're not readily available. They are very busy people. They can get in touch with me whenever they have the chance... 
 Justin H.: You can also see about emailing 
mobile@zte.com.cn to see if they can route your question to the development team. 
Erik S.: Or if you guys want to swap my ZMAX Pro for an Axon 7. I am specifically working on an application that is having bugs with ZTE handsets in particular and need need access to the bootloader to pull the logs. 
 Justin H.: Since the Zmax Pro is a carrier device, you would need to return the device to MetroPCS and then order a Axon 7. 
 Erik S.: You've been an incredible help, Justin. Thank you so much for your insight. 
 Justin H.: Are there any other questions I can answer today? 
Erik S.: Not at all. You have a stupendous day!!! 
 Justin H.: Thank you for choosing ZTE. Have a nice day and don't forget the short survey at the end of the chat. Just tap on disconnect at the top of the chat. 
 You have disconnected.
