Looking for Lollipop for Irulu X7 tablet.....

I want to run a newer firmware on my kids android Irulu X7 tablets with the sole purpose of being able to run the playstation vue app on them. They run kitkat 4.4.4 right now. I have an HTC One M8 that was rooted and running 4.4.2 and then I unrooted and did the RUU update to Marshmallow 6.0 so I am a little familiar with bootloader and rooting, etc., but by no means an expert. I do have some sdk/adb software on my computer that I was using with the HTC. So once again my goal is either get Playstation Vue running as is on their tablets or update firmware to get it running. Playstation says that the Vue app supports 4.4 and up, but tech couldn't solve my problem. I solved it for my phone, but their tablets don't have as much info. The app just says device isn't supported right now. I mention Lollipop because my wife's moto x is running that and the app works on her's.

Let me know any additional info you need and I'll get it.

PS Big thanks the guys on this forum. Got a lot of info while doing M8 stuff from here.
