Bought 3 lg Optimus S online to use with ting service. 2 of them worked great but the third one had been rooted and had cyanogenmod installed and was showing a meid for a HTC something or other instead of a lg Optimus S. I managed to unroot the device and return it to factory all except the MEID. can someone help me with fixing this. I found a tutorial online for fixing a corrupt MEID for a samsung phone but it doesn't work with the LG phone.
