you'll need to re-flash stock backup then repeat the procedure @ https://forum.hovatek.com/thread-116.html
First of all, is your m3 4.2 Old or new OS type (see the pictures @ https://forum.hovatek.com/thread-311.html to compare because this will tell us which MTK backup you should flash)?

My m3 is the old one. I have reflashed the stock ROM using cwm recovery and repeated the process but no progress

you're supposed to flash the MTK backup via Sp flash tool, not CWM backup via clockworkmod recovery.

do you have the MTK backup for old OS m3?
