Hi all, Did a n00b thing and never backed up my phone after rooting with z4. I was using Titanium backup to remove bloatware and got going pretty fast. next thing I know I deleted the com.motorola.contact system file....fml. I'm kinda new to the whole rooting thing and was wondering if it was possible just to reinstall that one file or if I could reinstall the whole OS. Also the phone has been having framework errors after I deleted the contacts system file. Any and all help would be greatly appreciated.
