    Description is fine, thanks for that.
    But for your information, I add to change the IMEI information not in emulator-arm, but in qemu-system-i386.exe (located in sdk/emulator/qemu/windows-x86_64)
    My suggestion to avoid looking at the wrong file is to check what is launched by the avd manager in the task manager.
