Default Help: how to restore the default framework-res.apk

Hello everyone, I need help on how to restore my stock framework-res.apk in my phone. It shows that some of my built-in app are not working anymore and i could not access the settings. I recently edit my framework-res.apk and push it to the system/framework and I reboot my phone. Maybe there something wrong that in my edited framework-res.apk. And I can not access the root using rootexplorer. How can I fix this using PC.?
