Why can't I switch the stock phone and camera icons in the menu to my own icons? I was able to change the gmail and the settings stock icons to the new ones I created... But, I keep getting errors on other icons. All I'm doing is pulling the apps in ADB to my desktop then replacing the icons in the apks with mine then pushing them back to my phone using these commands. I'm also trying to this auto-sign script where you just place the apk in the folder and it signs it for you. I keep getting these errors in ADB: c:\AndroidSDK>adb remount remount succeeded c:\AndroidSDK>adb push Camera.apk /system/app 1186 KB/s (546944 bytes in 0.450s) c:\AndroidSDK>adb install -r Camera.apk 1154 KB/s (546944 bytes in 0.462s) pkg: /data/local/tmp/Camera.apk Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE] ______________________________________________________ c:\AndroidSDK>adb push Phone.apk /system/app 1078 KB/s (701506 bytes in 0.635s) c:\AndroidSDK>adb install -r Phone.apk 800 KB/s (701506 bytes in 0.856s) pkg: /data/local/tmp/Phone.apk Failure [INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION] I don't why this keeps happening...any help would be much appreciated.
