Are there any ROMs available for the Huwaei Ascend Y530?

[AC Question]

I must have done at least 2 hours of searching the net to find this out, and I'm still not sure! I can't find any separate ROM threads on XDA, just some talk about some "MOD" thing or other. However, there are a number of sites touting a Lollipop ROM for the Y530. The download is nearly 600mb. But I've never heard of these sites and don't trust them! I'm not taking any chances, so I'm hoping someone here can give me the downlow on this great but wildly unpopular phone!
