phone model : lava iris 402+
Android version : 4.2.2

my phone is ROOTED. few days back i make a backup of 'download manager' with ES FILE EXPLORE. then uninstall it. then I Reset my phone. but next time when I use play store I can't download or update any app. it just show 'downloading' and nothg happen.

I also try to reinstall download manager from that backup Apk. but it shows 'not installed'.
and my keyboard is also not working after the reset. it shows ' unfortunately keyboard has stop working'

I also try to find some solution on google. but couldn't find much. mostly tells me to install new ROM. that I don't know how to do.

Is there a way in which I don't have to install new ROM.

plz help me solve this problem.

Thanks.
