sorry searched for you, but for this phone i have no fw
Edit:
found a person here in forum who has same phone as you, his name is "Hammtidammti" i already contact him and gave him the link to this thread, maybe he can help you
maybe you can use mtk droid tools. or just make nandroid backup from recovery. i really need the firmware. my phone is dead now. just bought it two days ago.
