if u cant get the sim unlocker app to work, follow the below instructions.
1. Download Minimal ADB and Fastboot tool from xda. (http://forum.xda-developers.com/showthread.php?t=2317790) and install
2. This will open a cmd prompt.
3. Enable USB debugging in your phone and enable RSA fingerprint also.
4. In the cmd window type
adb shell
U will be moved to a linux shell prompt in the cmd. there you type
su
you will be moved to root prompt with a # in front
in here you need to type
am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity
and enter, you will get a prompt in the phone , select API and Simlock and you are done.
Restart the phone after this.
This is what happens when I try the Minimal Adb method. What could be the problem?
