I have 2 nexus 5's. My first one stopped working(dropped it, no internet connection anymore) so I got the second one. I backed everything up from my old nexus 5. I restored it to my new nexus 5. Without thinking I flashed over the new nexus 5's EFS. Now my IMEI is 0 and I cant connect to the network. (WiFi works just fine).
I have tried resetting my phone to stock but that doesn't do anything.
Is there anything I can do? I have been searching for IMEI changers for the past couple of hours but everything I have tried doesn't seem to work.
Edit: I know changing IMEI's is illegal, but is there something I can do besides that?
