JB Upgrade Issues

[zephyrgard]

So the issues that I'm encountering are

1. Audio problems with Phone Calls(can't hear the person on the other end)

2. Mobile Data does not work. (It says it's connected but I can't run any apps that requires Internet Connection. Browsers just lags.)

Any ideas how I can revert back to ICS?

Have you tried to reinstall the update using SUS?

Let us know if this problem still remains after reinstall.

The mobile data not working might be caused by faulty settings so please check these with your service provider.
