look at the pictures in my last post, this is a custom ROM made by me. the Mt6573 isn't that fast, but i tried to make a fast ROM for it.
it is working pretty fast right now, no chinese apps and a lot of customization you can do . there are a lot of ROM's out there, some are good, some are pretty bad. like i said, i can make a flashable zip for your device, so you can try out my ROM.
