I'll post this again.
go to link below and download 60664.zip, extract, and place the extracted file on your sd card.
PRL 60664 - Download Included - xda-developers
1. you need to put the 60664.prl on the root of your sdcard
2. open up your dialer and dial ##775# (be patient, might take a minute or so)
3. it will ask you to enter your MSL number (Master Subsidy Lock), enter it
4. from the menu it brings up you will be able to update your prl with the file you placed on your sdcard. it will auto recognize it in the dropdown list if it's there.
5. Your phone should auto reboot itself after installing the prl and you should then be good to go.
If you need your MSL number call customer service and politely ask them for it. It's a 6 digit number. You should have no problems getting it from them. If they do happen to ask you why, tell them you need to manually update your PRL.
