I rooted my HTC one x and got the MaximusHD 21.0.0 ROM on it. When I turned my phone on everything seemed to be working. I restored all my apps and then rebooted my phone and inserted my SIM card. But I wasn't getting any signal and I remember reading that IMEIs can be lost or something like that so I checked my IMEI and it says unknown. When I turn on mobile data it says disconnected because service unavailable. I think it's a problem with the radio. Plz help me. If there's a way to fix, tell me how plz. If I need to install anything please give the link to download. Btw I'm a noob at these things so explain what to do in detail.
