Fastboot is accessible but refuses all useful commands, OEM unlock switch literally does nothing. As this is on pie, and has dm-verity enabled, the best way to go about doing this to find a CvE that we're vulnerable too. However since this phones secpatch is only a coulple months old, there have only been 2 worthy exploits, but we are not vulnerable to them. In order to root it before a zero-day exploit would to be able to find a zero-day on the device itself, which I don't have the expertise nor patience for.

+ First, I tried all the generic one click crap(KingRoot, Kingo, Etc.) as always since it's a Chinese phone.
+ Tried a few gray area tools like MiracleThunder, Uni-Android tool and such, come up empty handed.
+ I've tried every firehose from similar hardware available and they all seem to be fruitless ruling out EDL mode.
+ Fastboot is available but actively refuses commands.
+ OEM Unlock is a dummy toggle.
+ Hidden activity for "The Factory Upgrade" I haven't looked so much into, as like recovery it's probably looking for a signed zip.
+ CVE-2019-2215 and CVE-2019-10529 are dead ends, seems the kernel was patched correctly. Any older exploits e.g Dirty Cow variants outright fail as it has kernel 4.9+

Other notes: The ROM is buggy as hell, so they messed up somewhere I just haven't found it yet.

I really appreciate everything you guys are doing. This phone is my daily driver and the glitches drive me crazy! Can't wait for root/customer recovery.

Hummm u thought of everything and then a few things I thought of before reading this been playing with it a little oem unlock being dummy toggle is a boost Mobile thing my Stylo 3 had same issue and zte warp 7 if I remember the model name right idk how boost does it but they take something out to make it dummy toggle cuz with Stylo for example the metro pcs version that toggle works I did a little digging on that part also has anyone tried getting into recovery I did and couldn't get any menus to come up no matter what I tried I was half awake but none the less I was also wondering about if it would be possible to push root via abd or something in that way? if all this is dumb then I guess just just ignore it I'm just throwing ideas out atm not too sure where to start to try to get root on this phone

Metro is trying to push updates again. The numbers in the filename are the same. So I think it's the same one they tried to push last time. I still advise against it. The older the sec patch the greater a chance we have of getting in.

screenshot update

It's a button combo, I don't re!ember which I just use adb to reboot recovery, to get past the excliandroid into the recovery menus but adb is disabled other than sideload which still checks for the signature.
