I have an N7000 running Paranoid Android 2.1, which is based on CM10. As far as I can remember, I've always been able to connect to my phone via ADB, when USB Debugging is enabled in Settings.
The last time I connected was probably some time last week. As of today however, my phone refuses to connect via adb. adb devices gives a blank list and adb shell fails with device not found. The phone shows up fine as an MTP device.
I have all the requisite drivers, and I can connect using adb shell when I'm booted into ClockworkMod recovery.
Additionally, the "USB debugging" option seems to reset every time I reboot my phone.
Does anyone know of a potential solution to this that does not involve a full wipe and restore?
