[Q][HELP][mt6577] How Can I Determine What ROM is Comatible

Hi guys i've been searching this thread for sometime now for a Custom ROM that i can use for my Starmobile Diamond mt6577 and most of the threads that i ran to that has a hint for a possible install for my model give me second thoughts about flashing my unit. im not that knowledgeable when it comes to flashing roms but i know that even though most units have the same board model it doesn't mean that it has the same hardware and drivers right? with that said i was hoping that someone here is kind enough to tell me or direct me to a solution. below i'll provide some details about my phone and hope it'll somehow help.
