Don't know if this will help but​, I found that they lock the bootloader under the developer settings!

Has anyone tried a one click root application like KingoRoot ?
Or is this more for doing it on your own without a service like that?

Previously I had tried a series of one click solutions but I haven't found any that support this device yet. Typically they use the same exploits we've tried to use the hard way

After slacking for awhile I was finally able to poke around some of the internals of the phone in FTM mode using qualcomm developer tools. Lots of nifty things in the embedded file system and plenty of opportunities to flash new boot loaders and roms to the device for those of you who have a locked bootloader, but unfortunately I haven't been able to extract a copy of the stock rom or bootloaders. I'm still lacking the information I need to compile a new one for the phone.

Where I stand:
Can create a root shell, cannot remount system as read/write for permanent root in stock rom.
Can install new boot loader, no twrp or other found for this hardware.
Can compile new twrp, no boardconfig files (handy to avoid bricking your phone)
Can explore EFS and access chip via FTM, not sure how or if possible to download current rom / bootloader from here.

Happy for any tips on what to try next!

Can you tell me which tools you used? I looked at the Qualcomm site and there are plenty to choose from.

If you can get those tools off of the site maybe I'll message you about grabbing a few items on my Christmas list! QPST includes the tools necessary, and the tools to backup the 425 should you accidentally brick your phone (basically impossible to truly brick a qualcomm if you have the right tools). Archive.org has a copy, don't remember where to find the driver pack but you'll need that too (and a windows build).

Read through some notes on marshmellow and sounds like you have to remount system from recovery. I'm camping for the next month but will try talking to the TWRP team about porting a bootloader to the phone when I get back.

Let me know if you make any headway!

This page claims to have a root method but does it actually work? I've tried twice with no success.

How's everyone here? I also am awaiting root for this device. It really needs some shine on it's mid levelness. So here is my friend's​ zte warp 7 work for root. He also got some killer roms for the Huawei ascend XT. He does great work. I'm sure if he had a grand x 4 he could move this along. Just a suggestion. This man can this done. Just a suggestion for all of us. https://forum.xda-developers.com/sho...&postcount=246
