Default [Q] QMobile A55 stock ROM needed

I am developing a custom ROM for QMobile A55 based on Jelly Bean 4.2.2.
Few things are not working properly in the custom ROM.
I need some files from the stock ROM of QMobile A55, but I have accidentally deleted it from my computer.
Please, could anyone provide the backup of QMobile A55 stock ROM?
I specifically need the contacts, messaging and phone stock apps from it.
