Post GT-S7500 ACE Plus

Hi, I'm newbie here, I not really expert with this android method, anyway I've question here

I have 1 my ACE Plus (GT-S7500) now currently running with 2.3.6 GINGERBREAD Original Rom, I would like to update it to Jellybean (Official update) but when I try to google it and make research, I get that no more official update for this device especially Jellybean rom. Then I went to this forum. I saw, some post that told, it could be flashing with another custom rom to jellybean 4.2.2. but there some of function and features as camera flash, video recorder, wifi and etc could not working. Anyone got the perfect custom ROM that without any problem,.. I would like to have it,.. if possible it JELLYBEAN or KITKAT rom
