Help please OBQO T8!

[klio80]

good morning to all of you and sorry for my english help me with google!
I bought a mobile obqo on Whis with these features:
4G model number
Android version 6.0
MT6735 base band version
kernel version 3.0.8
hardware version A825E_V1.0
I installed kingRoot and gives me these other info:
4G brand
4G model
Android 4.0.3
CPU sc8825
kernel Linux version 3.0.8

I would like to know if it is a clone of some other mobile phone and how I can do to load other ROMs.
I apologize if I ask trivial questions but I'm a beginner!
Thank you for your precious help

I have tested the apk inside the rar.
It works well.

Do you have enabled "Unknown sources" onto Security ?
