I've got a ZTE Nubia Z5s mini and I'm looking for a good custom ROM for it. Now, my problem is all of the custom ROMs available seem to be for the 403a variant and not the 404h, which I have. My question is, are they cross flashable? Mine is still stuck on 4.3 and it bugs me that when I'm playing games I can't swipe down from the top to check out what notifications came in.
