Help me identify this tablet and whether there are custom ROMs for it

I was gifted this one device that I can't find any information online on, despite exhaustive searching. Internally, the tablet claims the following: >* Model number: S7Q >* Android version: 4.2.2 >* Kernel version: 3.0.36+ twp@server71 #525 >* Build number: S7Q_ZTE_PAD_EN.V2014.4 Naturally from this I would assume it is some ZTE device that would be called **S7Q** , but my searching of the internet only turned up that term a couple of times, both cases of a lone person on the XDA forum asking "what is this?" and getting no real answer. More searching seemed to suggest it was a Blade S7, but *Ask Mr Pigfish*, a software meant to identify a ZTE Blade model, reports that I have an "unknown model". I'd really like to figure this one out so I could root it and setup a custom ROM, and I'd appreciate any help!
