[Q] Identify my phone topic

Hi, a couple of yeas ago, I bought a Note 2 from craigslist then later found it was a fake. It was the same size, and model #, but I then started finding fake stuff. Stylus was fake. Screen size was off, cell signal stopped working, etc. It's running android 4.1.1. (baseband version MAUI.11AMD.W12.22.SP.V7.P3,2012/12/27 11:22). AnTuTu Benchmark was preinstalled with fake specs. So, I can't trust any specs I see in Settings, my guess it's some Chinese phone disguised as Note 2.

So, How can I identify the exact specs of the phone in hope that I can install a new ROM or cyanogenmod on it.

Any help is appreciated.
