Known issues Some SIM cards are not recognized. If you want to help debugging this, do the following: Run adb logcat -d -b radio > replicant_radio_log.txt after the device booted. Install CyanogenMod 13.0 and capture the same log. The output of adb shell dmesg after CyanogenMod has booted could be helpful, too. You can send the logs in a PM as they can contain personal information.
