ADB error: protocol fault (couldn't read status): Undefined error: 0

I'm trying to get adb to work on a macbook pro, but I can't get it right. I simply want to see the devices attached and continue from there, but I'm running into the most informative error message ever:

adb devices * daemon not running; starting now at tcp:5037 * daemon startenter code hereed successfully List of devices attached error: protocol fault (couldn't read status): Undefined error: 0

What I've tried: - Install android studio including sdk-tools

  • Delete Android studio completely and manual install sdk platform-tools (Current state)
  • Check .bash_profile for correct path (some left-overs still there. At the moment only the platform-tools folder exists):
export ANDROID_HOME=Users/r.dekker/Library/Android/sdk

export PATH=${PATH}:/$ANDROID_HOME/tools:/$ANDROID_HOME/platform-tools:/$ANDROID_HOME/tools/bin/
  • start virtual device from android studio, doesn't run.
  • A lot of google and stackoverflow searches. Didn't find anything that resembles my problem. Did find more logging. Does this make sense to anyone?
export ADB_TRACE=all

  • Vysor also doesn't recognise any device
  • Used different devices, different cables

Does one of you have an idea about a log I can check, something I can try again? To me it looks like nothing works and I'm forgetting something. Any ideas?

Try this. Disable Debugging option and enable again, check the USB port of android and clean it, same for cable and try again, and change mode from charging to file transfer.

The issue is not on the device, but on the development computer.

I resolved the issue by updating my Platform Tools from the SDK Manager in Android Studio.

With the issue:

$ adb --version
Android Debug Bridge version 1.0.41
Version 30.0.2-6538114

After upgrading:

$ adb --version
Android Debug Bridge version 1.0.41
Version 30.0.5-6877874
