adb server versión doest not match client

[tyoungIII]

When running adb devices I received the error:
adb server version (31) doesn't match this client (39); killing.. error: could not install *smartsocket* listener: Address already in use adb server didn't ACK

Already tried: adb kill-server and adb start-server, restarted the device. Did not work.

Hmm.. Try reinstalling ADB and check if it works.

Used the uninstall script and used the install script. No luck.

More about the device. Car multimedia video interface. Uses Allwinner quad-core T7 (arm)

Found out that the device has and in /sbin/adb-ec .

/sbin/adb-ec version
Android Debug Bridge version 1.0.31.5 -EC root

So I think there can be two possible causes of the problem. The first one - your ADB daemon version is not compatible with ADB server version. Second possible cause - you have some problems with PATH environment variable. Type in echo $PATH and post output here.

Likely the device has outdated client, you would need to install am older adb server if there is no update for client
