I have read so many posts and tried various things....but I just don't see any way to restore my IMEI and baseband (and get signal back!).
* I have tried a few of the other modems to no avail.
* I tried a restore from a backup I had of CM11 via CWM, but I'm guessing that doesn't backup the NVRAM settings.
* Attempts to use things like *#7284# yields "mobile network not available".
* the S3 doesn't seem to provide a COM port so I don't see how I could use NV-reader-writer even if I had a NVRAM backup file.....
