[Q] Chinese phone, custom rom?

Hello,
I bought this phone last month and got it a few days ago.
( ebay. ca/itm/121740001658?_trksid=p2060353.m2749.l2649&var=4207 36758310&ssPageName=STRK%3AMEBIDX%3AIT )

So far, the phone rocks.
However, when i got it it had Android 5.0.5 on it so i would like to find a ROM for either Android 4.2.2 or Android 5.0.5 to flash it with.

However, I can't find any info on the phone other than what's on the eBay page and i don't want to flash it and have a bricked phone... So, What is my best option here?
I was looking at something like SlimBean, Something clean and simple. Like SlimBean but like i said, I would hate to brick my phone.

Thanks,
Sorry if this is in the wrong section.
