Root ZTE Avail 2 (Z992) root help

So here is my issue, I have a ZTE Avail 2, a chromebook, and internet access. The chromebook is useless for running cydia impactor or anything else so I need a root method that does not require a computer. I have tried everything labeled "root no computer" on google and none have worked or bricked my phone. I am running Jellybean 4.1.1 and am not sure if it was ever updated since it is a used phone. If anyone can PLEASE help I understand it is an old phone but I have never had this issue, I have rooted many phones with many methods and have never hit a roadblock this big that not even the threads could help. I want to keep everything stock, the only reason I want it rooted is to delete the bloatware and maybe (if I get to keep THIS phone) tinker with a few other things. Thank you in advance to anyone who can help or knows a 100% successful method.
Just use someone else's computer! I used KingoRoot to root mine and it worked fine. I know a lot of others suggest Cydia Impactor, but I didn't use it because my PC through a fit over its security warnings (my browser wouldn't even let me get the file).
