Info 2 [Q] Force close after signing

Hey frnds, i just decompiled SystemUI.apk from my rom (MiniCM10) with framework installed of same rom..
I then recopiled the apk with touching/editing a single file from that decompiled folder..
And then i signed the apk..
And then i pushed to my system but i got force close.
I used differnt tools for signing apk but same force closes..
also i installed the whole rom with my signed apk bt still the same issue..
Ny solutions?? Plz help!!
