I actually did this as there's practically no support whatsoever for that counterfeit phone of mine (yeah I know, you get what you pay for, but I bought this Galaxy S7 clone mostly for science). None of the existing porting tools work for the MT6580, and while manually porting an existing TWRP image to my phone works, it simply isn't cutting it as most of these recoveries are designed for a conventional framebuffer setup, not on devices with flipped LCDs. Fortunately there's this source tree for the Infinix Hot 2 TWRP port, and as the partition setup seems to be largely the same apart from differing capacities and the aforementioned LCD issue, this had to be done.
This should theoretically work on HDC S7 clones and a few others albeit with a few modifications, though I ported this from source with the Z6U030/GXQ6580 in mind. I know the latter isn't as widely known as the HDC model, let alone the original, but oh well...

The recovery should work best on this ROM, but may also work on other devices provided you replaced the kernel with the one that came with your device:

My biggest props to the TeamWin team for making this little project of mine possible, as they're basically the ones who made this in the first place; I merely forked it to account for my device's configuration anyway. I'd also like to thank my pals over at American Girl Adult Collectors especially Amy and Molly, Arnee Libelo and Arturo of Driving Passion, and my buds Andy Vandjick and HardcoreHacker for the fun and expertise they shared.
