ADB is not starting (no error message)

Question

I am trying to run adb. When I run : "adb start-server" it hangs during a while, and then no message.

After that the command "adb get-state" receive the answer "error: protocol fault (no status)" If I run then "adb kill-server" the answer is "* server not running *"

I am using windows 7. An admin has elevated my rights to local admin, but it did not solve anything.

I used resources monitor to verify if any other app is using the ports of adb, but it is not the case.

on https://developers.google.com/chrome-developer-tools/docs/remote-debugging the step 3 indicates to "Enable USB Web debugging" under Settings > Advanced > DevTools. But on my test phone, there is no "advanced" category in the chrome settings. I couldn't find out either what is the version of chrome installed.

Somewhere on the web I saw a suggestion to change the rights of "tmp/android/" to allow read & write for all users, but in C:\Users\me\AppData\Local\Android\android-sdk\temp there is no android folder.

So I am pretty desperate now, any help would be immensely appreciated.

thanks

EDIT 1: I could't find "Enable USB Web debugging" because it was "android browser" and not chrome (a bit ridiculous yes). I did not know that. Using another device with a proper chrome installed, I could check the option there, but adb is still crashing at startup.

EDIT 2: I did a wild guess that there was some Write issue with the platform-tools folder. So I uninstalled everything using the sdk manager, I deleted the whole adt-bundle-windows-x86_64. Then I unzipped it elsewhere, on c:. Strange thing is, when I launch SDKManager.exe, several packages are already marked as installed :

• Tools>Android SDK Tools
• Tools>Android SDK Plateform-tools
• Android 4.2.2>SDK Plateform
• Android 4.2.2>ARM EABI v7a System Image
• Extras>Android Support Library

I tried deinstall them again, delete the folder, unzip again and re-install, but still same result. It seems that somehow, it is installed wrong, but refuses to uninstall properly. Anyone knows how to force the unistallation ?

EDIT 3 : output of adb start-server after having used set ADB_TRACE=1

Answer 1

Try this,

Open a command prompt with administration permission and type

netsh interface tcp set global autotuninglevel=disabled

This worked for me

Answer 2

Try setting the environment variable ADB_TRACE before starting the ADB server to see if it can provide any clues:

 C:\Android\android-sdk\platform-tools>set ADB_TRACE=1
 C:\Android\android-sdk\platform-tools>adb start-server

Please include the output in your question.

Answer 3

This solution worked for me:

=> Check if adb is running in Task Manager, then kill it. Now Then try to restart it again via following method:

1) Shift + Right click in ...\android-sdk\platform-tools folder and select Open command window here

2) Use these commands: adb kill-server then adb start-server

If this method didn't work and you see something like this in Command window Killing adb...

Then apply following steps:

3) Close eclipse

4) Now kill javaw.exe Java(TM) Platform SE binary in Task manager And follow step 1 & 2 again.

It will surely work. :)
