Rooting a TracFone ZTE Z233 - Android Q&A, Help & Troubleshooting

Hello all, I've come with an interesting problem.
I've recently purchased the incredibly cheap TracFone ZTE Z233, running "3.10.49-gdac61ef-00512-ge30dd04 zte-kerne;@Zdroid-SMT" and have decided to try and root it. After having gone through conventional methods, I would like to ask for your guys's input. I started by attempting the traditional methods, specifically downloading and attempting to run KingRoot.apk on the phone. The resulting message, "Cannot find an app to open this file" sent me to find the google play store. Upon the discovery that there was no google play store, I downloaded and ran the windows version of KingRoot on my PC after connecting the phone. Unfortunately, even though my PC recognized the device and was able to move files on and off of it, KingRoot could not find the phone.

Next, I tried to step through the directions Kingroot gave for enabling USB debugging as you can see in the second image. Unfortunately, I parsed through every single setting in the settings menu of the Z233, and no USB debugging option exists on this device. Upon discovering this, I attempted to find other means of rooting ZTE devices and discovered https://forum.xda-developers.com/showthread.php?t=1319257&page=1 was quite popular. However, this method also requires USB debugging. I won't bore you with the five or six other methods I tried, the issue always boiled down to the solution requiring a feature this phone did not have. The point is, as far as I can tell, there is no way to root this phone by conventional means.
I don't absolutely need to root this, (I bought it as a burner phone) but now I'm interested in rooting it as a project. I'm genuinely curious as to whether or not it can be done. I was hoping you guys would have some leads. I'm not afraid to get my hands dirty or do stuff that would risk bricking the phone (like I said, it was cheap.)
Any thoughts, questions or leads? Thanks!

I have ZTE Cymbal Z-320, which is quite similar to this. I can reach USB debug only in FTM mode (when phone is off, PWR ON + VOL DOWN and you in). Root apps are founding phone, tryying to root, but can't. It running android 5.1.1, read more https://androidforums.com/threads/zte-cymbal-z320-root-hack.1290564/
