I recently updated my Samsung S3 to Android 4.3 Earlier everything was working smooth but now my device is not getting listed in adb shell. It is getting connected but always shown "offline".

I tried all the solutions I found online :

• Changed USB port.
• Changed USB Cable.
• Pulled-out and restarted my device.
• Restarted System / Eclipse.
• Factory Reset of phone.
• Re-installed drivers.

Please HELP.

Answer 1

Try any one of these:

1. Enable the developer option in S3. I think it might be disabled after the update.
2. install Samsung android driver into your laptop.

[Please add any settings if I have missed]
