I already have root and have tried idones app to unlock, but for some reason, the unlock seems not to be working. The app says the phone is unlocked but when I insert a GSM sim card into the phone, it doesn't get any signal and the hands free activation loops. I was advised to go into settings -> mobile networks -> GSM, but the mobile networks setting disappears when I put in a GSM sim. It comes back if I put my Sprint sim is put back in. I also select GSM on that while my Sprint sim is in but when I take it out, that menu disappears. Is my phone unlocked or is it still locked? If its still locked, what steps can I take to unlock it given my current build and android version?
Idone should b able to help . Go to dialer, dial *#0011# ,
then in service mode press menu > back , then press menu > key input and type "Q" and press enter.
Then press menu > key input and type "0000" thats zero , 4 times .
The rest im copy n pasting from "jayfi" post iver at the us cellular forum
* - UE Settings & Info

* Make these selections above
* *Make sure you use the more button in the upper right corner to go back if needed(Back Key on phone will exit menu)
* Choose choice 7 “LTE/GSM MODE ONLY”
* Reboot
* Go to settings/Wireless & networks/more and it will allow you to add the correct APN

I'm having the same problem. It had worked when I originally unlocked my phone and put a simple mobile card in it. I tried to switch to my metro pcs card and now I'm not getting anything.
Help please.
