Hello, first post here.
A friend gave me a Verizon Motorola Droid Razr M model XT907. I'm on the Straight Talk network and they started a bring your own phone. After a little research I found this phone could be used if the GSM block was lifted. I successfully did this using the instructions found HERE. It worked perfectly until two days ago. I clicked on update system, when it finished, I lost connection. It had installed Jellybean v4.1.2. I tried using the RadioComm program to unlock the GSM again, but it doesn't work now. I need to go back to ICS at any cost. I'm without a phone now.
EDIT: this phone is not rooted
Any help will be greatly appreciated,
