[Q] Stock xperia e JB rom for tipo
I was thinking about porting the stock j.b. rom of the xperia e to tipo, because it's a nice rom, with a very nice UI, and also it could be a good upgrade for the xperia tipo, with an "official sony" touch. Since both phones are much alike in specs (they have same amount of ram, almost the same cpu, same screen, same gpu and same camera) I consider that this could be possible. So here's my question: how hard can it be? And also what would I need to make the port on an xperia tipo? Note that I'd like to port the official stock, generic one (rootable, if possible), with no modifications like UI, etc.
