[Q] SIM Unlock doesn't work
So I have an HTC One, it's running the latest Android Rev HD version (4.4). Recently my contract with Tmobile expired and I got a Lycamobile sim, along with an unlock code. I'm used to the network unlocking procedures, but for this HTC One, after I\ve typed in the code it says successful, rebooting, but doesn't reboot, simply freezes itself. After a while, it's responsive again, but it's showing the window for the unlock code again. I've tried putting the unlock code multiple times, each times is successful, rebooting but then again freezes and fails. What am I doing wrong? Is it the ROM ?
