ROM for my M8S (clone?)

[Lolos21]

Hello guys! I bought m8s. I think it's clone. Look the photos. I asked the seller if they have stock rom for my box and he told me that they don't have... Help me to find stock rom please!
I used this http://www.freak-tab.de/abdul_pt/aml/TWRP_M8.img TWRP to unroot my box and it worked. Do I have m8 box?
If you want any other information about my box, tell me.

Thanks.
