I reinstalled both frameworks pulled from my phone running Jelly 'Beans' build 14 and then decompiled SystemUI.apk and modified the tw_navi_bar.xml with notepad++ then saved and I get this error..

EDIT: I checked to see if there was a new version of apktool and there was so I downloaded it and put in my C:\APKTool directory and then tried to recompile the apk again and it worked. Thanks for all your help, its much appreciated.
